Everything You Need to Know About Wiper Blade Size

By CarsFellow 4 Min Read

As a car owner, one of the essential parts of your vehicle that you should regularly maintain is your wiper blades. Wiper blades help you to see clearly when driving in rainy or snowy weather. However, not all wiper blades are created equal, and it is important to understand the correct size of wiper blades for your car. In this article, we will discuss everything you need to know about wiper blade size, including H2 and H3 built points.

Why Wiper Blade Size Matters

The size of your wiper blades matters because the wrong size can affect their effectiveness in cleaning your windshield. If the wiper blade is too small, it may not effectively clean the entire surface of your windshield, leaving streaks and potentially dangerous blind spots. On the other hand, if the wiper blade is too big, it may not fit correctly, leading to poor performance and damage to the blade or the windshield.

How to Determine the Correct Wiper Blade Size

To determine the correct size of wiper blades for your car, you need to refer to your car owner’s manual or use an online tool such as the wiper blade finder. The owner’s manual will have information on the size of the wiper blades you need for your specific make and model. Alternatively, the wiper blade finder can provide you with the exact wiper blade size you need by inputting your car’s make, model, and year.

Common Wiper Blade Sizes

Wiper blade sizes vary depending on the make and model of your car. However, there is some common wiper blade size that you can find in most vehicles. These include 16 inches, 18 inches, 20 inches, 22 inches, and 24 inches. Some cars may require two different sizes for the driver’s side and passenger’s side wipers, so it is important to check your owner’s manual or use the wiper blade finder tool.

Tips for Replacing Your Wiper Blades

Replacing your wiper blades is a simple and inexpensive process that you can do yourself. Here are some tips for replacing your wiper blades:

Check Your Owner’s Manual

Before purchasing new wiper blades, check your owner’s manual to determine the correct size and type of wiper blades for your car.

Choose Quality Blades

Invest in quality wiper blades that are designed to fit your car’s make and model. Cheaper wiper blades may not fit correctly or provide adequate cleaning, leading to poor visibility.

Replace Both Blades

It is recommended to replace both wiper blades at the same time, even if only one is showing signs of wear. This ensures that both blades are working effectively and reduces the risk of one blade wearing out faster than the other.

Regularly Replace Your Wiper Blades

It is important to replace your wiper blades every six months to a year, depending on their usage and wear. Over time, wiper blades can become damaged or worn, leading to reduced effectiveness and potential damage to your windshield.


In conclusion, understanding the correct wiper blade size for your car is crucial for maintaining good visibility while driving in inclement weather. By referring to your owner’s manual or using an online tool, you can determine the correct size of wiper blades for your specific make and model. Remember to invest in quality blades, replace both blades at the same time, and regularly replace your wiper blades for optimal performance.
