What Size Of Wiper Blades Should I Buy For My Car?


The wiper blades of your car are a safety feature, whose importance you always forget until you encounter driving in rain or snow. An unclear windshield is truly a hazard while you are driving. It is also a known fact that majority of the accidents that happen are a result of poor visibility.

Your wiper blades do have their service life, during time when their performance would be highly efficient. They eventually tend to get worn out and do not work properly as they are on a constant exposure to harsh physical conditions of weather and atmosphere. It is extremely important to change your wiper blades as and when required to ensure a safe driving experience. Knowing what size wiper blades would be necessary for your car helps to a greater extent.

When Should You Change the Blades?


It is time to change the wiper blades of your car when you notice the following symptoms:

  • Streaking noise when they wipe the moisture off your windshield
  • Improper wiping of the surface
  • ​Your wiper leaves a milky film of material while wiping
  • When you turn the wipers on, they do not move as they are stuck to the glass

The rubber material used in your wiper blades wear out easily with usage. It is advisable to change your wiper blades twice in a year and also based on the type of blades used. Rubber wiper blades do not last long, and they need to be replaced regularly. Halogen-hardened rubber blades last a little while longer, whereas Silicone blades have the longest lifetime. The cost of these blades also varies according to the durability.

Why Not Just Change the Rubber Blades?

The rubber blades of your wiper are available in the market, which is cheaper. If you opt to get them changed, instead of replacing your entire wiper blade, it is cost effective. But you should also remember that fitting the rubber blade over your wiper is a tedious task, and you can easily change the entire wiper instead of put your effort and time on to fitting the rubber blade.

How to Choose the Wiper Blade Size for Your Car?


The wiper blades of your car operate in a semicircular motion, thus clearing the surface and promoting a better visibility. When you observe the wiping action of your blades, you will realize that the top corner of the passenger side and lower corner of the driver’s side of the windshield are not cleaned properly.

This is because of the size constraint of the wiper blades. Hence you might think it is better to get bigger sized wiper blades when you are about to replace them. But is it a good idea? What size wiper blades would best suit your car? Let us see how to choose them.

1. Refer to Your Car’s Manual


The size of the wiper blades is specific to a car’s model. Hence grab your car’s manual and look for the data on what size wiper blades are used. This will help you to buy the exact size of the blades which are suitable for your car.

If you replace your car’s wipers with smaller sized blades, they do not wipe out effectively. They even miss wiping the critical visibility areas, thus not serving the purpose. If you replace the wipers with larger sized blades which protrude outside your windshield, then there are chances that the two wipers collide with each other while wiping. They also tend to wear out prematurely.

2. Use an Online Blade-Size Finder

You can use the www.rainx.com Rain-X website or any other Wiper blade manufacturer’s portal such as TricoProducts.com, which is incorporated with a wiper blade size calculating tool. This online calculator computes the optimal wiper blade size that is required for your car.

You will have to input the year, make and model name of your car before hitting the ‘Find my Blade’ button. You will be provided with detailed information about the required blade size, design, model, where to buy, installation information and more information regarding the same.

3. Get Your Measuring Tape

You can measure the wiper blade size manually by using a measuring tape. To measure the length of the wiper blade, lift the blade away from the windshield. Press the blade, so that it extends to become straight from its curved position. Measure its length from one end to the other in inches. Also take measurements of the driver side and passenger side wiper blades separately, as their sizes are different.
