How to Measure Wiper Blades?

Choosing the right wiper blades for your vehicle is crucial for maintaining visibility and driving safety, especially in rainy conditions. If you're unsure how to measure them, don't worry—this guide will help you get it right.

To measure your wiper blades, you'll need to know their full length, including both the rubber and the frame. This measurement ensures the blade fits correctly and clears your windshield effectively. Let's dive into how to measure and select the right wiper blade size for your vehicle.

Understanding the correct way to measure your wiper blades is the first step to ensuring they work effectively. Let’s break down the details of each question so you can confidently choose the right wiper blades for your vehicle.

How do I know what size my wiper blades are?

Knowing the size of your wiper blades is essential for ensuring they fit your vehicle correctly. If you’ve never measured them before, it can be tricky to know where to start.

The easiest way to determine your wiper blade size is to check the vehicle manual or measure the length of the blade. If you're unsure, most auto part stores offer guides based on your car make and model to help you find the right fit.

To determine your wiper blade size¹, follow these steps for accurate measurement:

1. Check the Vehicle Manual

Most vehicles have a recommended wiper blade size mentioned in the manual. This is the easiest way to find out what size you need without any measuring. However, if you don’t have access to the manual, don’t worry—you can measure the blades yourself.

2. Measure the Wiper Blade

To measure the wiper blade² yourself, you’ll need to measure the full length, including both the rubber and the frame. Take a measuring tape and stretch it from one end of the wiper blade to the other, making sure to include the entire length of the blade. This measurement will give you the correct size.

3. Check for a Match

Once you have the measurement, it’s time to match it to the size offered by wiper blade manufacturers³. Sizes are typically listed in inches, so be sure to round the millimeter measurement to the nearest inch.

1. Check Manual	Look for the recommended size
2. Measure Blade	Measure from tip to tip
3. Match Size	Round millimeters to nearest inch

Can you use a 17-inch wiper blade instead of a 16?

You may be tempted to swap out your wiper blades for a different size if you don’t have the exact replacement. But is it okay to use a 17-inch blade instead of a 16-inch? Let’s find out.

In most cases, you should avoid using a wiper blade that’s a different size from the original. A size mismatch can affect performance and cause uneven wiping, leading to poor visibility. Let's discuss the impact of switching to a different size.

When it comes to wiper blades⁴, size matters. Even a small difference in size can significantly affect how well the wiper performs. Here's why it's important to use the correct size⁵:

1. Fitment Issues

A wiper blade that is too long may extend past the edge of the windshield, causing it to not make full contact with the glass. This can lead to gaps in coverage, leaving areas of your windshield unswept. Additionally, longer blades may obstruct the wiper’s range of motion, causing unnecessary stress on the wiper system.

2. Uneven Pressure

If the blade is too short, it might not cover the entire windshield, leaving streaks or areas that aren’t wiped properly. On the other hand, a blade that's too long can exert uneven pressure, causing it to wear out more quickly. This can result in uneven wiping and decreased cleaning performance.

3. Increased Wear and Tear

Using the wrong size can cause the wiper system to work harder, leading to increased wear and potentially damaging the motor or linkage over time. Always stick to the manufacturer-recommended size⁶ for optimal performance.

Factor	16-Inch Blade	17-Inch Blade
Wiping Coverage	Full coverage	May miss areas
Pressure Distribution	Even	Uneven
Wear and Tear	Normal	Increased wear

How do you measure your window wipers?

Measuring window wipers might sound simple, but it’s important to ensure the measurement is accurate to avoid choosing the wrong size. Here’s a straightforward method for measuring them.

To measure your window wipers, you need to measure from one end of the blade to the other, including both the rubber and the frame. Accurate measurement is essential for finding the right replacement.

Here’s a step-by-step guide on how to measure your window wipers:

1. Remove the Wiper Blade

Before measuring, lift the wiper arm away from the windshield. This allows you to get a precise measurement of the blade itself. Carefully remove the blade from the arm, if necessary, to measure it separately.

2. Measure from Tip to Tip

Using a tape measure, stretch it along the entire length of the wiper blade⁷, including the rubber part and the metal frame. This measurement will give you the total length of the blade.

3. Check Your Results

Once you have the measurement, round the length to the nearest inch⁸ for the correct size. Keep in mind that wiper blades come in standard lengths, and your measurement should match one of these sizes.

Step	Action
1. Remove Blade	Lift wiper arm, remove blade
2. Measure Blade	Measure from tip to tip
3. Check Results	Round measurement to nearest inch
