The size you need is the blade length specified for your vehicle. Check the owner’s manual, inspect the current blade for its length, or use an online parts finder by year, make, and model.
Ways to determine the correct size
To determine the correct rear wiper blade size, use these reliable methods. They cover official specifications, physical measurements, and smart shopping tools.
- Check the owner's manual or the vehicle manufacturer's website for the rear wiper blade size recommended for your model.
- Look at the current blade or its packaging for a printed length or part number that you can cross-check.
- Remove the blade and measure its length with a tape measure, from the mounting point to the tip of the blade, including only the blade itself.
- Note any OEM part number on the blade and use it to look up the exact size on the manufacturer’s site or a reputable parts retailer.
- Use an online “blade finder” tool by entering your year, make, model, and trim to get a recommended size.
- If you’re unsure, visit a parts counter or service department with your VIN or the old blade to confirm the correct size.
Following these steps will help you identify the correct rear wiper blade size for your vehicle and reduce the chance of buying the wrong length.
Confirming fit and understanding mounting styles
Mounting styles and adapters
Rear wiper blades attach to a variety of arms, including hook-style and pin-type adapters. Some blades come with universal adapters to fit multiple arms, but you must still match the correct length. Check the blade packaging for compatibility notes, and if your arm uses a special connector, choose a blade model designed to fit that connector or ensure the included adapters match your arm.
When replacing, ensure you select a blade that matches both the length and the mounting style of your existing arm. A wrong length or an incompatible adapter can cause poor wiping performance or damage to the arm.
Summary
In short, the right rear wiper blade size is the blade length your car requires. Start with the owner’s manual or current blade, verify with a part number, measure if needed, or use an online vehicle lookup tool. Confirm mounting compatibility before purchasing, and you’ll ensure a clean, streak-free rear sweep every time.
