Measure the length of the rubber blade with a ruler to determine the wiper blade size. Here is some information about wiper blades: 1. The technical name for a wiper is "Windshield Wiper," a blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Its primary function is to clear rain, snow, and dust that obstruct visibility on the windshield. 2. If the wiper arm does not indicate the model or length, you can measure the rubber blade's size. Lay the wiper flat and use a ruler to measure the length at both ends. Unit conversion: 1 inch is approximately equal to 2.5 cm.

Last time I changed my wiper blades, it was quite a hassle. Measuring the size isn't actually difficult—the simplest way is to check the vehicle's manual; the maintenance parts list in the last few pages will definitely have the wiper specifications. If you find that troublesome, you can measure it directly: gently lift the wiper arm (be careful not to let it snap back and hit the glass), measure from the metal clip to the top of the rubber blade, and only measure the length of a single blade—the driver and passenger side blades might differ by a few centimeters. Nowadays, many new wiper packages list compatible car models, and online shopping platforms can automatically match them based on your license plate number. However, I recommend verifying the measurements when the product arrives. Once, I encountered a case where the labeled size was 1 cm shorter than the actual requirement, which affected the wiping performance. Remember to check the rubber blades for wear every six months, and replace them promptly if they don’t wipe cleanly.

Using a tape measure is the most reliable method: After turning off the engine, move the wipers to the service position. Start measuring from the metal bracket connection point of the wiper, following the rubber blade to the farthest end. The sizes for the driver and passenger sides may differ, with most cars using combinations like 26+16 inches or 28+14 inches. If that's too troublesome, check the steel imprint on the side of the rubber blade—numbers like '650mm' indicate the length. Once, while helping a neighbor, I found that half of the factory-printed number on his original rubber blade was worn off. In such cases, you'll need to remove the wiper and check the label at the connection point. Nowadays, wipers sold in supermarkets specify compatible models on the packaging, such as 'Fits Corolla 2017-2022.' Buying based on this information is usually foolproof.

Here's a tip: When searching for wiper blades on Taobao, simply enter your car model and year, and the system will automatically recommend the matching size. However, it's best to double-check three things: first, the numbers engraved on the side of the old wiper rubber strip from your car; second, the label near the base of the driver's side wiper; and third, the parts page in the user manual. I've encountered cases where online purchases labeled as 'universal for Honda' turned out to be half a centimeter shorter. Wiper blades aren't better just because they're longer—if they exceed the windshield range, they can hit the bottom frame, and if they're too short, they won't reach the edges. If you're replacing them yourself, remember to place a cloth under the wiper arm when lifting it to avoid accidentally cracking the glass if it slips.

When cleaning the windshield this morning, I noticed a crack on the right wiper blade. Remember these three points when measuring the size: Remove the wiper, lay it flat, and measure the full length of the rubber for the most accurate measurement; Check the type of connecting clip (U-hook or straight plug varies by car model); Search for maintenance posts on car forums using your phone, like searching 'wiper size' in the Volkswagen Lavida forum for detailed data. Last time I borrowed a friend's car, I found the wiper packaging box still in the glove compartment, printed with 26'/16'. A reminder for southern car owners: Always check your wipers before the rainy season. When the rubber strips age, they can skip, shake, and make squeaky noises, which is especially dangerous when driving at night.
