Most Hummer H3 models use a two-blade front setup with a 22-inch driver-side blade and a 20-inch passenger-side blade. Exact sizes can vary by year and market, so verify your vehicle’s specification before purchasing replacements.
Common front-wiper sizes for H3
Two front blades are standard on the H3. The sizes below reflect the most commonly reported configurations across model years 2006–2010, with some variants using small deviations. Use this as a baseline and verify on your vehicle.
- Driver-side blade: 22 inches

These sizes cover the majority of H3s produced during the model's run. If your H3 is a special export variant or a custom build, sizes could differ by 1–2 inches.
How to confirm the exact size for your H3
To ensure you order the correct blades, use one of these verification methods:
- Check the current blades for size markings (often printed on the blade or adapter).
- Look in the owner's manual or the vehicle's window sticker for blade lengths recommended by the manufacturer.
- Use an auto parts retailer's fitment tool—enter your year, make, and model to see compatible blade sizes.
- If in doubt, measure the blade length from end to end or bring the old blade to the store for comparison.
Verifying the exact size helps prevent purchasing mistakes, especially for export variants or special trims of the H3.

For the Hummer H3, the typical front-wiper blade sizes are a 22-inch driver-side blade and a 20-inch passenger-side blade. Confirm with your owner's manual, the current blades, or a reputable retailer's fitment tool to ensure you have the correct sizes for your specific year and market. Regular replacement with quality blades keeps visibility clear and driving safer.
