Can I use a 21 wiper blade instead of 20?
The short answer is that you can generally use a 21-inch wiper blade instead of a 20-inch one, as long as the 21-inch blade fits your vehicle's wiper arm. However, there are a few important considerations to keep in mind when making this substitution.
Wiper Blade Size Compatibility
Wiper blades come in a variety of sizes to fit different vehicle models. The size refers to the length of the blade, not the width. Most passenger vehicles use wiper blades that range from 16 to 26 inches in length. 1 2
When replacing a wiper blade, it's important to match the size to what the vehicle manufacturer recommends. This ensures the blade will properly fit the wiper arm and provide full coverage across the windshield.
Using a Slightly Larger Wiper Blade
In some cases, you may be able to use a wiper blade that is slightly larger than the recommended size. For example, if your vehicle calls for a 20-inch blade, a 21-inch blade may work as a replacement. 4
The key is that the larger blade must still fit securely on the wiper arm without any gaps or overlaps. It should also provide full coverage across the windshield without leaving any uncovered areas.
Potential Drawbacks of Mismatched Sizes
Using a wiper blade that is significantly larger or smaller than the recommended size can lead to several issues:
- Poor windshield coverage, leaving streaks or uncovered areas
- Improper fit on the wiper arm, causing the blade to wobble or come loose
- Increased wear and tear on the wiper arm and windshield
- Potential safety hazards from reduced visibility
Therefore, it's generally best to stick to the manufacturer's recommended wiper blade size whenever possible. Only consider a slightly larger size if it's a close match and provides a secure, full-coverage fit.

Can I use shorter windshield wipers?

Do wiper blades have to match?
Though some vehicles have wipers that are the same length, most have subtle differences between the left and right side. This is evidenced through the fact that when buying new blades, most come with the driver and passenger side separately labeled.
Can you oversize wiper blades?
Using a larger wiper blade than what is advised for your car can reduce visibility and put additional stress on the wiper motor.
Do wiper blades have to be the exact size?
Windshield wiper blades are vehicle specific. On some vehicles, both wiper blades are the same size. On other vehicles, the two wiper blades are different sizes. The optimal wiper blade size is determined by the manufacturer and selected for proper fit to clear as much of the windshield as possible.
Can you cut wiper blades to size?
Tip: If you cannot find refills that match the length of your blades, buy the closest to your size and cut them using a knife to match your length. Ensure the width of the wiper refill matches your blade width.
What happens if you use the wrong size wiper blade?
Using the wrong size wipers can lead to inadequate coverage, streaking, or even damage to your windshield.

Does Size Really Matter? Size matters to a point, just as long as you are about 1 inch higher or lower than your current wiper blade size. If you buy wiper blades that are too big, they might overlap or touch which will cause them to break.
Does it matter what wiper blades I use?
There are conventional blades, but there are also beam and hybrid designs. All three of these types work with all vehicles and there is no right choice. Depending on your budget, the climate you live in, and how long you want them to last one type may be a better choice than the others.
