What is the size of my windshield wipers?

Most passenger cars use two front blades, typically about 22–24 inches on the driver's side and 18–22 inches on the passenger side. The exact size for your vehicle should be verified in the owner's manual, on the sticker inside the driver’s door jamb, or on the packaging of the replacement blades you plan to buy.

How to find your exact blade size

Use these steps to confirm the correct lengths for your car, which helps you avoid buying the wrong size and ensures optimal wiping performance.

1. Check your vehicle’s owner’s manual or the manufacturer’s website for the recommended front blade sizes for your model.


2. Inspect the current blades for length marks or a part number printed on the blade or on the mount.


3. Measure the blades if markings are not available: remove the blade and measure from tip to tip with a tape measure; do not measure just the rubber edge.


4. When in doubt, use an OEM or reputable aftermarket replacement finder by entering your vehicle’s year, make, and model to get exact sizes.

Following these steps will help you identify the correct blade lengths and ensure you purchase the right replacements.

Typical blade sizes by vehicle type

Sizes vary widely by model, but the ranges below reflect common configurations you’ll encounter in the market:

• Passenger cars (compact to midsize): driver’s blade often 18–24 inches; passenger blade commonly 16–22 inches, with examples including 22/18, 24/18, or 20/16 inch pairings depending on the model.


• SUVs and crossovers: driver’s blade commonly 22–26 inches; passenger blade 18–22 inches; many models use 26" and 18" or 24" and 18" configurations.


• Trucks and full-size SUVs: driver’s blade frequently 26–28 inches; passenger blade 20–22 inches.


• Rear wipers: typically 10–14 inches, varying by design.

These guidelines are general; always confirm with official specs for your specific vehicle to ensure proper fit and performance.

Practical tips for replacing windshields

Buy the right sizes in pairs

Most cars require two different front-blade lengths. If you replace one blade, verify that the other remains the correct length, or replace both to ensure balanced clearing and even wear.

Check compatibility and features

Consider blade technology (beam vs. conventional), winter-specific blades, and install method compatibility with your vehicle’s wiper arms and sensors. A proper fit also matters for preventing streaks and ensuring even pressure along the windshield.

Summary

To determine the size of your windshield wipers, consult your owner’s manual or the vehicle’s official specifications, examine the current blades for length marks or part numbers, or measure the blades directly. Sizes typically range from about 18 to 28 inches for front blades, with two different lengths common on many cars and shorter rear blades. Using the correct sizes ensures clear visibility in rain, snow, and sleet, and makes replacements straightforward.

How do I find out what wiper blade I need?

You can also find the right replacement wiper blade by looking in your car's owner manual, on the side of the old blade or potentially even on the box of your new blades – just look for your cars make or model on the packaging or leaflet.

How do I know my windshield wiper size?

You can find your windshield wiper size by checking your owner's manual, using an online wiper size finder tool on an auto parts store's website, or by measuring the blades currently on your car. It's important to note that the driver and passenger side blades may be different lengths, so check both. 
Method 1: Check your owner's manual

• Your vehicle's owner's manual should list the correct sizes for the front and rear wipers. 
• Look for a section about the windshield wipers or maintenance. 

Method 2: Use an online tool

How to find the correct size

Can I use 24 instead of 22 wiper blades?

Using a larger blade might introduce unwanted stress on the wiper motor, as it wasn't designed to accommodate the extra weight and drag. This can potentially lead to premature wear or even failure of the motor system, which isn't cheap to replace.
