What size wiper blades for GMC Acadia?

Typically, replacement wiper blades for a GMC Acadia are 28 inches on the driver's side and 22 inches on the passenger side for the front, with a rear blade around 12 to 14 inches depending on the year and model.

To ensure you choose the correct sizes for your specific vehicle, identify your year and trim and verify with the owner's manual or an official GM parts catalog. This article provides the general sizes and a quick method to confirm your exact blade length.

Front wiper blades: standard sizes

Most GMC Acadias use a two-blade front setup. This section covers the typical lengths you’re likely to need when replacing the front windshield wipers.

• Driver-side front blade: 28 inches


• Passenger-side front blade: 22 inches

These front sizes cover the vast majority of models built in recent years. If your Acadia seems to require different lengths, double-check with your vehicle's year-by-year specifications.

Rear wiper blade: size guidance

The rear wiper on many Acadias is shorter than the front. The exact length varies by year and configuration, but the common range is roughly 12 to 14 inches.

• Rear blade length is typically 12 inches on older models; newer models often use about 14 inches.

Using the right rear blade size ensures proper fit and effective wiping, since a blade that's too long or too short can skip or miss areas of the rear window.

How to verify the exact size for your Acadia

To ensure accuracy, check one of these reliable sources:

• Owner's manual under the wiper blade replacement section


• GM official parts catalog or the GM Parts website by entering your year, make and model


• Measure the current blades if you still have them: remove and lay them flat on a ruler or tape measure to confirm the length

By confirming the precise measurements for your specific year and trim, you’ll avoid buying the wrong size and ensure optimal wipe performance.

In summary, most GMC Acadias require 28" driver and 22" passenger front blades, with rear blades typically in the 12–14" range. Always verify using the owner's manual or a trusted parts lookup for your exact year and trim.
