When it comes to sizing windshield wiper blades, every vehicle is different. Some vehicles, for example, have two wipers of the same size. Others, though, might have a larger driver-side wiper blade and a smaller passenger-side blade. And don’t forget: Many hatchbacks, SUVs and minivans also have a smaller, rear-window wiper blade.

If it’s time to replace your wipers, chances are you’re wondering how to determine the size of blades that you will need.

It’s important that you find the accurate size. Installing new windshield wipers that are the wrong size will result in reduced functionality, and at worst, might even damage your wiper system. Fortunately, there are a few ways drivers can determine the size of the wiper blades for their vehicle.

Tips for Choosing and Sizing Wiper Blades

Before you determine size, it’s often best to take a look at the connection of your wiper blades. There are three main types – including side post, J-hook and bayonet wipers – and this refers to how the new blades are installed. For example, J-hook wiper blades are attached to the blade holder, which is attached to the windshield, by clamping a J-shaped hook. This is an important differentiation, as J-hook wiper blades won’t fit in a side post or bayonet system and vice versa. In addition, you’ll also want to consider the performance of the blades.

Plus, drivers should consider the performance of the blade. Research has shown that wiper blades typically last 6 months to 1 year, regardless of price, and there are different types for different seasons. Drivers in rainy environments would benefit from wipers designed to handle heavy rain, while those in winter climates would benefit from winter blades.

Finally, once you’ve determined the style and performance of the blades, you can figure out what size works. Here are three strategies:

• Measure Existing Blades: Typically, wiper blades are available in various sizes measured in inches. Thus, you can measure your existing blades and then purchase blades of the same size. Be careful to get as accurate a measurement as possible and to measure both blades. Many vehicles use two wiper blades of differing sizes.
• Consult Owner’s Manual: Your vehicle’s owner’s manual contains valuable information about your wiper blades, including the sizes used and connection type. Plus, the owner’s manual will also inform you have to replace and install new wiper blades.
• Use an Online Parts Locator: Auto parts stores and online retailers typically have parts locators available. You enter the make, model and year of your vehicle, and the database returns the type and size of blades that will fit your vehicle.
