Westinghouse 20.63-Inch Replacement Fan Blades are my best overall pick for shoppers seeking replacement blades for a compatible 52-inch fan, while the Lineshading 5-pack in wood offers a different finish and the Westinghouse 16.5-inch blades serve compatible 42-inch fans. The main tradeoffs are matching the blade length and mounting pattern, choosing a finish that suits the room, and deciding whether a five- or ten-pack makes sense. Some listings include blades only, while another supplies blade arms, so checking what the kit contains matters. Compatibility can vary even among fans with the same stated diameter. Read on for the full comparison and a guide to choosing ceiling fan replacement blades that fit your fan.

Key Takeaways
- Fan diameter alone does not confirm fit: the lineup separates into common 42-inch and 52-inch fan sizes, but mounting-hole layout and blade geometry still need checking.
- Westinghouse offers several distinct length options: its 16.5-inch, 20.5-inch, 20.63-inch, and 22-inch listings are not interchangeable just because they serve similarly sized fans.
- Pack count changes the value calculation: Lineshading has both five- and ten-blade packs, which may suit full replacement or keeping compatible spares, but only if the fit is right.
- Finish choices serve different rooms: white, wood-look, black, and clear acrylic options give buyers more control over appearance, with acrylic standing apart from conventional finishes.
- Parts included vary: most picks are blade packs, while the black 52-inch kit is listed as blade arms; check the contents before assuming a purchase includes both.

More Details on Our Top Picks
Westinghouse 20.63-Inch Replacement Fan Blades for 52-Inch Ceiling Fans
For a 52-inch outdoor fan, this five-blade set makes the most sense when weather exposure is the main concern. Its weatherproof plastic construction is a practical choice for replacing worn blades in an outdoor setting, while the stated outer-hole dimension gives you a useful fit check before ordering. Compared with the Lineshading 5 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, White, Westinghouse provides a specific hole measurement and calls out outdoor use directly; the Lineshading option instead lists a waterproof finish and white appearance. The tradeoff is that “most standard” does not mean universal: blade length alone cannot confirm that the mounting holes match your fan. I’d measure the old blade and mounting pattern carefully, and skip this set if you need a verified fit for an unusual model.
Pros:- Weatherproof plastic is suited to outdoor fan use
- Five blades provide a complete replacement set for a five-blade fan
- Specified outer-hole diameter offers a concrete compatibility check
- Designed for most standard 52-inch outdoor ceiling fans
Cons:- Fit is not guaranteed across all 52-inch fan models
- Plastic construction may not suit buyers seeking a wood appearance
- Existing blade and hole measurements still need to be checked
Best for: Owners of standard 52-inch outdoor ceiling fans replacing five weather-exposed blades who can check the mounting dimensions first
Not ideal for: Buyers who cannot measure their existing blade holes or need a guaranteed match for a nonstandard fan
- Blade count:5
- Blade length:20.63 inches
- Intended fan size:52 inches
- Blade material:Plastic
- Outer hole diameter:3-15/16 inches
- Room type:Outdoor
- Special feature:Weatherproof
- Mounting type:Ceiling
Our verdict“Choose this set for a standard outdoor 52-inch fan when weather resistance matters and your mounting measurements match.”
16 1/2″ Replacement Fan Blades and Arms for 42 Inch Ceiling Fans
This set is distinct from blade-only replacements because it includes matching arms as well as five blades. That makes it a better fit for a 42-inch fan whose existing arms are also damaged or mismatched, and the included hardware is aimed at a straightforward DIY replacement. The chestnut brown veneer finish offers a warmer look than the white Lineshading 5 Pack 16.5″ Replacement Fan Blade for 42″ Ceiling Fan, White, while the warp-resistant core is intended to help the blades keep their shape. The added parts are also a tradeoff: if your fan arms are sound, a blade-only kit may be a simpler match. Compatibility still depends on the fan’s mounting pattern, so measure before buying, and skip this set if your fan is not a standard 42-inch model.
Pros:- Includes five blades and matching arms
- Hardware is included for a DIY installation
- Warp-resistant core is intended to help maintain blade shape
- Chestnut brown veneer gives a warmer finish than white replacement sets
Cons:- Limited to 42-inch fan applications
- Extra arms may be unnecessary when only blades need replacement
- Fit still depends on matching the existing fan and mounting pattern
Best for: DIY owners of standard 42-inch indoor fans who want to replace both blades and arms in one repair
Not ideal for: Owners with intact fan arms, nonstandard mounting patterns, or fans outside the 42-inch size class
- Intended fan size:42 inches
- Blade length:16.5 inches
- Blade count:5
- Included components:Matching arms and hardware
- Finish:Chestnut brown
- Material:Warp-resistant core with veneer
- Use:Indoor
Our verdict“Pick this kit when a 42-inch indoor fan needs both new blades and arms, rather than blades alone.”
Lineshading 10 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, White
The standout here is the 10-blade quantity: it suits owners who want spares on hand or have more than one compatible fan to repair. Each blade is listed at 20.5 inches long and 5.375 inches wide, with pre-drilled holes and a white engineered-wood construction. Compared with the Lineshading 5 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, White, this set provides twice as many blades, but that extra quantity is useful only if you have a need for it. The product data says it fits 52-inch fans with up to five blades, so confirm both the fan size and mounting pattern before relying on the fit. Though described as waterproof and weatherproof, it is also described as primarily recommended for indoor use; I would not choose it over Westinghouse’s outdoor-focused plastic set for exposed locations.
Pros:- Ten blades provide spares or coverage for multiple compatible fans
- Engineered-wood construction with a white finish
- Pre-drilled holes simplify the installation process
- Waterproof and weatherproof properties are specified
Cons:- The larger quantity may leave buyers with unused blades
- Product information primarily recommends indoor use despite water-resistance claims
- Compatibility varies by fan and requires measurement
Best for: Owners repairing multiple compatible 52-inch fans or those who want matching spare blades for future replacements
Not ideal for: Buyers who need only one five-blade set or want a clearly outdoor-focused replacement for an exposed fan
- Blade count:10
- Blade length:20.5 inches
- Blade width:5.375 inches
- Intended fan size:52 inches
- Material:Engineered wood
- Color:White
- Compatibility:52-inch ceiling fans with up to 5 blades
- Water resistance:Waterproof and weatherproof
Our verdict“Choose this pack when you can use the extra blades and have verified that the dimensions and holes match your 52-inch fan.”
Lineshading 5 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, White
For a buyer who needs exactly five matching blades, this Lineshading set keeps the choice simple: it pairs a white finish with pre-drilled holes and a stated 20.5-inch length for 52-inch fans. Unlike the 10-pack Lineshading option, it avoids extra blades that may go unused. Its listed width of 5⅜ inches helps with comparison against an existing blade, though the product data does not identify the blade material. That missing detail makes it harder to judge the construction against the engineered-wood 10-pack or Westinghouse’s plastic outdoor set. Waterproofing is claimed, but I would still check the fan’s mounting pattern and the manufacturer’s guidance before using it in a highly exposed outdoor spot. This is a practical, appearance-led replacement, not the clearest choice for buyers prioritizing material transparency.
Pros:- Five blades match a common replacement need without the surplus of a 10-pack
- White finish suits fans where a light, unobtrusive look is preferred
- Pre-drilled holes can make installation more direct
- Waterproof design is specified
Cons:- Blade material is not specified
- Compatibility is limited to 52-inch fans and still requires measurement
- Outdoor suitability is less clearly detailed than in Westinghouse’s outdoor-focused set
Best for: Owners of five-blade, 52-inch fans who want a white replacement set and can verify its dimensions and mounting holes
Not ideal for: Buyers who need material specifications, a different blade count, or a confirmed fit for a nonstandard fan
- Blade count:5
- Blade length:20.5 inches
- Blade width:5⅜ inches
- Intended fan size:52 inches
- Material:Not specified
- Color:White
- Water resistance:Waterproof
- Installation feature:Pre-drilled holes
Our verdict“Choose this set for a measured, compatible 52-inch fan when you want five white blades and can accept unspecified material.”
Lineshading 5 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, Wood
This five-blade set is the clearest fit in this group for buyers who want a wood finish rather than white or plastic. Its listed 20-inch length and 5⅜-inch width give you dimensions to compare with your original blades, while the waterproof finish is intended to add flexibility for indoor and outdoor use. Against the white Lineshading 5 Pack 20″ Replacement Fan Blades for 52″ Ceiling Fan, this version offers a wood appearance and identifies its material; against the Westinghouse 20.63-Inch Replacement Fan Blades, it trades plastic weatherproof construction for a wood option. The stated fit is limited to 52-inch fans with five or fewer blades, and “wood” alone does not identify a wood type or finish details. Measure the mounting holes before ordering.
Pros:- Wood material provides a different appearance from white or plastic blades
- Five blades suit a common replacement configuration
- Waterproof finish is specified for indoor and outdoor use
- Pre-drilled holes support a more direct installation
Cons:- Fit is limited to 52-inch fans with five or fewer blades
- Wood type and detailed finish characteristics are not provided
- Existing dimensions and mounting pattern must be checked
Best for: Owners of compatible 52-inch fans who prefer a wood look and need a five-blade replacement set
Not ideal for: Buyers seeking a specified wood species, a verified universal fit, or blades for fans outside the 52-inch size class
- Blade count:5
- Blade length:20 inches
- Blade width:5⅜ inches
- Intended fan size:52 inches
- Material:Wood
- Water resistance:Waterproof finish
- Compatibility:52-inch ceiling fans with 5 or fewer blades
- Mounting type:Ceiling mount
Our verdict“Choose this option for a compatible 52-inch fan when a wood appearance matters more than detailed material specifications.”
5 Pcs 52’’ Ceiling Fan Blade Arms Replacement Kit – Black
This kit replaces blade arms, not the blades themselves, so it suits a different repair than the Westinghouse 7741500, which supplies five complete blades. Its zinc alloy arms may help restore a steadier, quieter fan when worn or damaged supports are the problem, letting you keep blades that still fit and are in good condition. The pack contains five arms, but compatibility depends on matching both the 3.9-inch blade-side hole width and the 2.1-inch motor-side hole width, as well as the thread specification. The tradeoff is a less plug-and-play repair: mounting screws are not included, and some blades may need drilling. I would avoid drilling wooden blades unless the work can be done safely and accurately.
Pros:- Five zinc alloy arms can replace a complete set of worn supports
- May help address wobble or noise caused by unstable blade arms
- Lets buyers keep serviceable existing blades rather than replace the full set
Cons:- Mounting screws are not included
- Fit depends on precise hole-width and thread compatibility
- Some blade installations may require drilling, which risks damaging blades
Best for: Owners of a 52-inch fan with damaged or unstable blade arms who have verified the mounting-hole measurements and want to retain their existing blades
Not ideal for: Buyers whose blades are cracked or missing, or anyone who cannot match the hole spacing and thread size; this kit does not include replacement blades or mounting screws
- Material:Zinc alloy
- Package quantity:5 blade arms
- Arm dimensions:6.7 × 4.3 × 2.7 inches
- Blade-side hole width:3.9 inches (100 mm)
- Motor-side hole width:2.1 inches (52 mm)
- Thread specification:10-24UNC
Our verdict“Choose this kit to replace matching, damaged blade arms while keeping your existing blades; skip it if you need blades or cannot verify the measurements.”
CroBlissful 5 Pcs 16.5” Clear Acrylic Ceiling Fan Blades for 42″ Fans
The CroBlissful set is the lineup’s clear acrylic choice, for buyers who want replacement blades to make less visual impact than the white Lineshading 5 Pack 16.5″ Replacement Fan Blades. Its five 16.5-inch blades are listed for fans up to 42 inches, and pre-drilled holes reduce the work of preparing each blade for mounting. Acrylic is described as waterproof, giving this set a stated indoor-and-outdoor use case that contrasts with the indoor-focused Westinghouse 7741500. That visual and moisture-resistant appeal comes with a fit-check requirement: blade length alone does not prove that the hole positions will match a particular fan. The protective film also needs removal, and the product data gives no detailed blade profile or mounting dimensions beyond its stated size.
Pros:- Clear acrylic offers a distinctive alternative to white or wood-look blades
- Five blades provide a full replacement set for a compatible fan
- Pre-drilled holes can simplify installation
- Waterproof material is described as suitable for indoor and outdoor use
Cons:- Protective film must be removed before use
- Hole spacing and exact fan compatibility should be checked before purchase
- Transparent styling will not suit buyers seeking a traditional blade appearance
Best for: Owners of a compatible 42-inch fan seeking clear replacement blades for a modern look and a stated indoor-or-outdoor option
Not ideal for: Buyers who want a conventional wood or white finish, or who need confirmed hole spacing before ordering; the listed fit information may not settle compatibility with a specific fan
- Package quantity:5 blades
- Blade size:16.5 × 5 × 0.12 inches
- Material:Acrylic
- Stated fan compatibility:Fans up to 42 inches
- Weight:1.88 pounds
- Installation detail:Pre-drilled holes
- Use:Indoor and outdoor, as described
Our verdict“Pick these for a clear, contemporary look on a measurement-matched 42-inch fan, but choose the white Lineshading set if you want a more conventional finish.”
Westinghouse 7741500 Replacement Fan Blades, 22-Inch, 5-Pack
For buyers replacing a complete set on a standard 52-inch indoor fan, the Westinghouse 7741500 is the clearest fit in this group: five 22-inch blades and reversible oak-and-walnut finishes. That two-sided finish gives it more decor flexibility than the single-color Lineshading 5 Pack 16.5″ blades, which are intended for smaller 42-inch fans. The main tradeoff is material: the product data describes the blades as plastic, so buyers seeking a wood blade should look at the Lineshading wood set instead, while checking fan size and mounting compatibility carefully. This option is also listed for indoor use only, making it a poor match for exposed outdoor locations. Verify the existing blade dimensions and attachment pattern before ordering; a 52-inch fan label alone does not confirm fit.
Pros:- Five blades form a complete replacement set
- Reversible oak and walnut finishes offer two appearance options
- 22-inch blades are specified for compatible 52-inch fans
- Plastic construction avoids the need to match a real-wood finish
Cons:- Listed for indoor use rather than outdoor exposure
- Plastic material may not suit buyers seeking wood blades
- Compatibility is limited to the stated 52-inch fan size and still requires a mounting-pattern check
Best for: Owners of an indoor 52-inch ceiling fan who want five replacement blades with reversible oak and walnut finishes
Not ideal for: Buyers replacing blades on a 42-inch fan, seeking wood construction, or fitting a fan in an outdoor or exposed setting
- Package quantity:5 blades
- Blade length:22 inches
- Stated fan compatibility:52-inch ceiling fans
- Blade material:Plastic
- Reversible finishes:Oak and walnut
- Use:Indoor
- Mounting type:Ceiling mount
Our verdict“Choose this set for a compatible indoor 52-inch fan when reversible finishes matter more than wood construction or outdoor suitability.”
Lineshading 5 Pack 16.5″ Replacement Fan Blade for 42″ Ceiling Fan, White
This Lineshading set is the straightforward pick for a white five-blade replacement on a stated 42-inch fan. Its 16.5-by-5-inch dimensions put it in the same size class as the clear CroBlissful acrylic blades, but the white finish is less visually distinctive and may blend more easily with light-colored rooms. Pre-drilled holes are intended to make installation simpler, while the waterproof finish is described as suitable for indoor and outdoor fans. The biggest limitation is uncertainty: the blade material is not specified, so buyers cannot compare its construction directly with CroBlissful’s acrylic or Lineshading’s wood version. The 42-inch fit also should not be assumed from length alone; check mounting-hole positions against the original blades before replacing a set.
Pros:- Five blades provide a complete set for a compatible fan
- White finish suits a range of light or neutral interiors
- Pre-drilled holes are intended to simplify fitting
- Waterproof finish is listed for indoor and outdoor use
Cons:- Blade material is not specified, limiting construction comparisons
- Fit is stated for 42-inch fans and may not suit other sizes
- Mounting-hole alignment should be confirmed against the existing blades
Best for: Owners of a compatible 42-inch fan who want a simple white replacement set and value a stated water-resistant finish
Not ideal for: Buyers who need a known blade material, a wood or transparent appearance, or blades for a fan outside the stated 42-inch size
- Package quantity:5 blades
- Blade length:16.5 inches
- Blade width:5 inches
- Stated fan compatibility:42-inch ceiling fans
- Material:Not specified
- Color:White
- Water resistance:Waterproof finish
Our verdict“Choose this set for a white, water-resistant replacement on a measurement-matched 42-inch fan; opt for CroBlissful if a specified acrylic material and clear finish matter more.”
Lineshading 5 Pack 16.5″ Replacement Fan Blades for 42″ Ceiling Fan, Wood
Where the white Lineshading 5 Pack prioritizes a simple, light finish, this version is the lineup’s wood-blade choice for a 42-inch fan. The five 16.5-by-5-inch blades have a stated water-resistant design and pre-drilled holes, making the set a candidate for buyers who want a warmer look without moving to a different fan size. Unlike the Westinghouse 7741500, which is listed as plastic with reversible oak and walnut finishes for 52-inch fans, this product is specified as wood and targets a smaller fan. The tradeoff is narrow fit: it is listed for 42-inch fans with up to five blades, and buyers still need to confirm the mounting pattern. The description calls the blades wood, but does not identify a wood species or finish details.
Pros:- Wood construction offers a warmer alternative to the white Lineshading set
- Five blades provide a full set for compatible fans with up to five blades
- Pre-drilled holes are intended to simplify installation
- Water-resistant design is listed for indoor and outdoor use
Cons:- Compatibility is limited to the stated 42-inch fan size and up to five blades
- Mounting-hole alignment still needs to match the existing fan
- Wood species and finish details are not specified
Best for: Owners of a compatible 42-inch fan with five or fewer blades who want a wood replacement set and a water-resistant design
Not ideal for: Owners of 52-inch fans, fans with more than five blades, or buyers who need a specified wood species and detailed finish information
- Package quantity:5 blades
- Material:Wood
- Blade size:16.5 × 5 inches
- Stated fan compatibility:42-inch ceiling fans
- Maximum blade count:Up to 5 blades
- Weight:1.9 pounds
- Water resistance:Water resistant
- Mounting type:Ceiling mount
Our verdict“Pick this set for a wood-blade look on a compatible 42-inch fan with no more than five blades, and choose the white version if you prefer a simpler finish.”
16.5-inch Ceiling Fan Replacement Blades – Pack of 5 for 42-inch Fans
For a 42-inch fan used indoors or outdoors, this five-blade set stands out for its waterproof coating and included mounting hardware. The pre-drilled holes, 25 screws, and 25 washers make it a more complete replacement package than the Westinghouse 16.5-Inch Replacement Fan Blades, which list installation instructions but not included fasteners. The wood-colored finish also offers a warmer look than the plain white Lineshading 10-Pack 16.5-inch blades. The tradeoff is fit: these blades are specified for 42-inch fans, so the fan’s blade length and mounting pattern need to match before ordering. This is a practical pick when replacing all five blades on a compatible fan, but it is not a universal repair kit.
Pros:- Waterproof coating supports use in outdoor settings
- Includes five blades plus 25 screws and 25 washers
- Pre-drilled holes simplify installation when the mounting pattern matches
- Wood-colored finish provides an alternative to plain white blades
Cons:- Specified only for 42-inch ceiling fans
- Requires checking blade and mounting-hole fit before purchase
- Wood-colored finish may not match every fan or room
Best for: Owners of compatible 42-inch fans who want a complete five-blade replacement set for an indoor or covered outdoor space.
Not ideal for: Buyers with 52-inch fans, a different mounting pattern, or a fan that needs replacement blade arms as well as blades.
- Blade length:16.5 inches
- Blade width:5 inches
- Quantity:5 blades
- Compatibility:42-inch ceiling fans
- Material and finish:Wood-colored blades with waterproof coating
- Mounting:Pre-drilled holes
- Included hardware:25 screws and 25 washers
- Intended use:Indoor and outdoor
Our verdict“Choose this set for a compatible 42-inch fan that needs five coated blades and included mounting hardware.”
Westinghouse 16.5-Inch Replacement Fan Blades for 42-Inch Ceiling Fans
The main distinction here is reversible white and bleached oak finishes, which let buyers change the visible side without adding a separate set of blades. That makes this a flexible indoor choice for a compatible 42-inch fan, while the 16.5-inch wood-colored set from B0GX1H9F9Y is the better match when outdoor use and included screws and washers matter more. Westinghouse supplies installation instructions and says the set fits most 42-inch fans with up to five blades, but “most” is not a guarantee of matching hole placement. Buyers should compare the mounting pattern and blade shape with their existing parts. The stated indoor-only use is a real limit, and careful, even installation matters for avoiding imbalance.
Pros:- Reversible white and bleached oak finishes offer two appearance options
- Includes installation instructions
- Designed for most 42-inch fans with up to five blades
- Five blades provide a full replacement set for a compatible five-blade fan
Cons:- Listed for indoor use only
- May require modification on some fan models
- Installation and blade balance require care
Best for: Indoor-fan owners with a compatible 42-inch model who want a choice between white and bleached oak finishes.
Not ideal for: Buyers replacing blades on an outdoor fan or anyone whose fan has a nonstandard mounting pattern or more than five blades.
- Blade length:16.5 inches
- Quantity:5 blades
- Compatibility:Most 42-inch ceiling fans with up to five blades
- Material:Plastic and engineered wood
- Finish options:Reversible white and bleached oak
- Weight:2.3 pounds
- Intended use:Indoor
- Installation information:Installation instructions included
Our verdict“Pick this Westinghouse set for an indoor 42-inch fan when reversible finishes and included instructions matter more than outdoor suitability.”
Lineshading 5 Pack 20-inch Replacement Fan Blades for 52-inch Ceiling Fans, Waterproof and Weatherproof, Black
This is the lineup’s clear option for buyers who need black blades for a 52-inch fan and want a weather-resistant finish. Its plastic construction and waterproof coating suit indoor or outdoor use, unlike the indoor-only Westinghouse 20.5-Inch Replacement Fan Blades for 52-inch fans. The black finish also gives a more modern, high-contrast look than Westinghouse’s reversible white and bleached oak blades. At 20.5 inches long and 5⅜ inches wide, these blades still require a careful fit check; matching the fan’s overall size alone may not confirm the mounting pattern. The five-blade quantity suits compatible fans with five or fewer blades, but buyers should plan to replace the set together rather than mix old and new blades.
Pros:- Waterproof finish supports indoor and outdoor use
- Black color offers a distinct alternative to white or wood-look blades
- Pre-drilled holes simplify installation when the pattern matches
- Five blades suit compatible fans with up to five blades
Cons:- Compatibility is limited to 52-inch fans with five or fewer blades
- Mounting-hole fit still needs verification
- Replacing only one blade may leave the fan unbalanced
Best for: Owners of compatible 52-inch fans who need a black five-blade set for an indoor or outdoor location.
Not ideal for: Buyers with fans outside the 52-inch class, more than five blades, or a mounting pattern that does not match the pre-drilled holes.
- Quantity:5 blades
- Blade length:20.5 inches
- Blade width:5⅜ inches
- Compatibility:52-inch ceiling fans
- Material:Plastic
- Finish:Waterproof, black
- Mounting:Pre-drilled holes; ceiling mount
- Intended use:Indoor and outdoor
Our verdict“Choose this set when a compatible 52-inch fan needs black, weather-resistant replacement blades.”
Lineshading 10-Pack 16.5″ Replacement Fan Blades for 42″ Ceiling Fan, White
With 10 white blades in one package, this set is better suited to buyers who want spares on hand or have more than one compatible fan than to someone replacing a single five-blade set. Its 16.5-inch size is intended for 42-inch fans with up to five blades, and the waterproof finish adds flexibility beyond the indoor-only Westinghouse 16.5-Inch set. However, the product description still recommends primarily indoor use, so I would not treat the coating as proof of suitability for exposed weather. Compared with the wood-colored five-pack from B0GX1H9F9Y, this option offers more pieces and a simpler white look, but it does not list screws and washers. Measure the existing blades and check the hole pattern before buying.
Pros:- Ten blades provide a spare set or coverage for multiple compatible fans
- Waterproof finish adds some flexibility beyond standard indoor blades
- Pre-drilled holes support straightforward installation when aligned
- White finish suits a range of fan and room styles
Cons:- The ten-piece quantity may exceed the needs of a single five-blade fan
- Primarily recommended for indoor use despite the waterproof finish
- Fit can vary, so measurements and hole placement need checking
Best for: Owners of one or more compatible 42-inch fans who want extra white replacement blades available for future repairs.
Not ideal for: Buyers needing only one five-blade set, a non-white finish, or replacement blades for a fan with a different size or hole pattern.
- Quantity:10 blades
- Blade length:16.5 inches
- Blade width:5 inches
- Compatibility:42-inch fans with up to five blades
- Color:White
- Material and finish:Durable blades with waterproof finish
- Mounting:Pre-drilled holes
- Intended use:Primarily indoor
Our verdict“Choose this set if you want extra white blades for compatible 42-inch fans and can verify the mounting fit.”
Westinghouse 20.5-Inch Replacement Fan Blades for 52-Inch Ceiling Fans
For a compatible 52-inch fan, Westinghouse’s strongest differentiator is its reversible white and bleached oak finish, paired with fit measurements that help buyers compare blade-arm holes before installation. That makes it a more decor-flexible indoor option than the black Lineshading 20.5-inch set, which is the better choice for weather exposure. The package contains five blades and includes detailed instructions, offering a straightforward route to a matched replacement set. Still, compatibility is described as “most” 52-inch fans, not all, and the listing limits use to fans with five or fewer blades. The product data gives hole measurements but does not specify blade material durability, so buyers prioritizing an outdoor-rated finish or confirmed material details may prefer another option.
Pros:- Reversible white and bleached oak finishes give two styling choices
- Five blades provide a full set for a compatible fan
- Detailed instructions support a more guided installation
- Hole measurements help buyers check compatibility before ordering
Cons:- Designed for fans with five or fewer blades and may not fit every model
- No outdoor-use rating is provided
- Material durability details are not specified
Best for: Owners of indoor 52-inch fans who want reversible white and bleached oak blades and can match the listed hole spacing.
Not ideal for: Buyers with outdoor fans, more than five blades, or models whose blade-arm measurements differ from the listed dimensions.
- Compatibility:Most 52-inch ceiling fans
- Quantity:5 blades
- Blade length:20.5 inches
- Finish options:Reversible white and bleached oak
- Outer hole measurement:3-15/16 inches
- Center hole distance:2-3/4 inches
- Blade-count limit:Designed for fans with five or fewer blades
- Installation information:Detailed instructions included
Our verdict“Pick this set for a compatible indoor 52-inch fan when reversible finishes and listed mounting measurements are useful.”
How We Picked
I ranked these ceiling fan replacement blades by the details that determine whether a replacement is useful: stated fan size, blade length, pack count, finish, material, and whether the listing identifies blades, arms, or a kit. Fit came first because an attractive finish or larger pack cannot compensate for blades that do not line up with the fan’s mounting pattern. I also weighed how clearly each option serves a distinct buyer need, such as replacing blades on a 42-inch fan, matching a 52-inch fan, choosing a wood finish, or buying a larger pack.
The ranking favors options with a clear use case and recognizable specifications, rather than treating all similarly sized listings as interchangeable. Westinghouse options rank highly for buyers who can confirm compatibility and want a defined replacement length; Lineshading options add useful pack-size and finish choices. Specialized picks, including clear acrylic blades and replacement arms, rank lower for general use because they suit narrower needs. Product names and listed dimensions do not establish compatibility with every fan, so I treat manufacturer fit information and the original blade pattern as necessary checks.
Factors to Consider When Choosing Ceiling Fan Replacement Blades
Before choosing a finish or pack size, I would work from the fan you already own. Replacement blades are not universal: the right purchase depends on the fan’s mounting hardware and the blade dimensions, not just the room’s appearance or the fan’s advertised diameter.
Match the Fan Diameter and Blade Length
Start with the fan’s model number or manual, then compare its specified blade length and replacement part details with the listing. The 42-inch options here generally list 16.5-inch blades, while many 52-inch options list blades around 20 inches, but those patterns are not a universal rule. A fan’s diameter describes the sweep across the room, not a guarantee that any blade of a given length will fit. Measure an existing blade from the mounting point as well as checking the full blade length if documentation is missing. Avoid choosing by fan diameter alone; even a small mismatch can change the blade sweep or prevent proper attachment.
Check Mounting Holes and Blade Arms
Compare the number, spacing, and orientation of the mounting holes on the old blade with the replacement listing. Some fans attach blades directly to the motor, while others use separate arms; a pack of blades may not include those arms. The black 52-inch option in this roundup is identified as a blade-arm kit, which makes its contents different from a standard blade pack. If a blade is damaged but its arm is sound, a blade-only set may be enough; if the arm is bent or cracked, replacing blades alone may leave the problem unresolved. When the hole pattern is unclear, look up the fan’s exact model before ordering.
Choose a Finish That Fits the Existing Fan
White blades are a straightforward match for many light-colored fans, while wood-look and black finishes can make a replacement more visible as part of the room’s design. Clear acrylic has a more distinct appearance and may suit buyers who want a less conventional look, but it will not blend in like a standard opaque blade. Check whether the listing describes the finish on one side or both if your fan can reverse its blade direction. A finish mismatch can be more noticeable when replacing only one blade, so replacing the full set may give a more consistent appearance. Color names alone can be imprecise; compare listing images and product details with the existing fan.
Decide Between Five and Ten Blades
Many ceiling fans use five blades, making a five-pack a natural choice for a full set when the fan’s design matches. A ten-pack may be useful when replacing more than one fan or keeping compatible spares, but the larger quantity does not make an incorrect blade a better buy. Check how many blades your fan uses before ordering, especially if it has an unusual configuration. Buying a complete matching set can avoid the visible variation that may come from mixing old and new blades. If you only need one replacement, confirm whether the manufacturer permits mixing blades from different batches or finishes.
Treat Material and Weather Claims Carefully
Material affects appearance, weight, care, and where a blade may be suitable, but a product title alone cannot establish that it suits every room or installation. The lineup includes conventional white and wood-look options, clear acrylic, and a black listing described as waterproof and weatherproof. For a covered porch or other damp location, check the fan’s own indoor or outdoor rating as well as the blade listing; replacing one component does not change the fan’s rating. Avoid assuming that a weather-related description means a blade can handle direct exposure. If the fan is installed outdoors, follow its manufacturer guidance for both the motor and replacement parts.
Replace a Balanced Set and Recheck Operation
Uneven blade weight or mismatched shapes can contribute to wobble, noise, or inconsistent airflow, so replacing the full set is often a safer route than mixing one new blade with several worn ones. Before installation, compare the replacement blades side by side and confirm each one matches the same dimensions and hole pattern. Follow the fan maker’s instructions for fastening and use the specified hardware rather than improvising with screws that seem close. After fitting the blades, run the fan at a low speed and watch for wobble before using higher settings. If vibration continues, stop the fan and check installation, blade balance, and the condition of the arms.
Frequently Asked Questions
Can I use 16.5-inch blades on any 42-inch ceiling fan?
No. The 16.5-inch measurement in a listing does not confirm the blade’s mounting pattern, shape, or compatibility with every 42-inch fan. Check the fan model and compare the blade’s hole spacing and attachment method with the original. Also confirm that the manufacturer’s replacement guidance allows that blade length. If you cannot identify the model, measurements from the existing blade and arm can help narrow the options, but they do not replace a fit check.
How do I choose between the 20.5-, 20.63-, and 22-inch options for a 52-inch fan?
Use the fan’s specified replacement blade length rather than assuming those measurements are interchangeable. The difference in length can affect the blade sweep, clearance, and fit at the mounting point. Compare the original blade from its mounting area to its tip, then verify the hole pattern and model compatibility in the product details. If the fan manual names a part number, use that information to guide your choice. When details conflict, contact the fan manufacturer before ordering.
Should I buy a five-pack or a ten-pack if I only need to replace one blade?
First check whether the replacement matches the existing blades in shape, finish, length, and mounting holes. A full five-pack can make it easier to keep the set visually consistent and avoid differences between old and new blades. A ten-pack is more useful if you have multiple compatible fans or want spares, not simply because one blade needs replacing. Confirm the fan’s blade count and whether the seller offers a smaller quantity. Mixing a new blade with worn or differently finished blades may be noticeable and can affect balance.
Do replacement blades include the blade arms and mounting screws?
Not necessarily. Many listings in this roundup are described as blade packs, while the black 52-inch option is identified as a blade-arm replacement kit. Product titles may not list every included component, so inspect the package details before ordering. Compare the included hardware with what your fan needs, and do not assume that blades-only packaging includes arms or screws. If an arm is damaged, choose a compatible arm or kit rather than attaching a new blade to a compromised part.
Can I use weatherproof replacement blades on an outdoor ceiling fan?
A weatherproof description on a blade listing does not by itself confirm that the part is suitable for every outdoor fan or exposure level. Check the fan’s outdoor rating and its manufacturer’s approved replacement parts, then verify that the blade mounts correctly. Covered and exposed locations can have different demands, and the motor’s rating still matters even if the blades are described as weatherproof. Do not treat a component claim as a rating for the whole fan. If the listing does not specify the conditions it supports, ask the seller or manufacturer before installation.
Conclusion
For a broadly useful starting point, I rank the Westinghouse 20.63-inch blades as best overall, provided their dimensions and mounting pattern match your 52-inch fan. The Lineshading five-pack in white is my best-value direction for buyers who want a standard finish, while the Lineshading wood five-pack is a better fit when appearance is a priority. Beginners should start with the Westinghouse 16.5-inch option only after confirming their 42-inch fan’s model and attachment pattern; clear product sizing makes comparison easier, but does not make it universal. For specialized needs, consider the clear acrylic blades for a distinctive look, the ten-packs for multiple compatible fans or spares, and the blade-arm kit when arms—not just blades—need replacement. My final recommendation is to verify the fan model, blade length, and mounting holes before choosing any finish or pack size.
