What is the windshield wiper size conversion chart?
2 Answers
Windshield wiper size and length conversion: 14"--350mm; 16"--400mm; 18"--450mm; 20"--500mm; 21"--525mm; 22"--550mm; 24"--600mm; 26"--650mm. For every additional inch in wiper size, the length increases by 25mm. Methods for selecting windshield wipers: 1. Wiper type: First determine the specific wiper model your vehicle uses by consulting the owner's manual. 2. Compatibility: Check whether the connection method between the wiper arm and the wiper blade matches your vehicle. Some arms are secured with screws while others use snap-on locks. 3. Inspection: Lift the wiper and run your fingers along the cleaned rubber blade to check for damage and elasticity. If the rubber shows signs of aging, hardening, or cracking, the wiper needs replacement.
Actually, the wiper sizes vary for each car model, and there's no universal reference table to rely on. I've replaced my wiper blades several times and found that the most reliable method is to check the owner's manual, which usually lists the wiper specifications in the last chapter. For my Volkswagen Lavida, the driver's side is 26 inches and the passenger side is 19 inches. I once mistakenly bought a pair of 24-inch blades, and they couldn't clean the corners properly. If you can't find the manual, here's a tip: remove the existing wiper blades and check the side of the rubber strip—it often has the exact size engraved on it. Those so-called reference tables online are often inaccurate. Last time, I bought wipers based on data from a platform, and they ended up colliding when installed. The safest way is to measure the original wiper size with a tape measure, then allow for a 3mm margin of error when purchasing new ones.
