In detail: This sizing is common for the 2001 Suburban (GMT-400). However, production changes, trim differences, or aftermarket replacements can yield variations.

Front wiper blade sizes
The two front blades on a 2001 Suburban are typically different lengths: 22 inches on the driver’s side and 20 inches on the passenger side. This arrangement provides adequate coverage across the windshield. If you see different lengths, it could be due to aftermarket replacements or an unusual service part.
Rear wiper blade size
The rear window blade is generally 12 inches in length for the 2001 Suburban. This size fits the rear wiper arm commonly found on GMT-400 models of that era. If another length is installed, confirm compatibility with your vehicle’s year/model.
How to verify exact lengths
To ensure you order the correct blades, measure your current blades end-to-end or refer to the owner's manual or a GM parts catalog using your VIN. When shopping, look for front blades labeled 22 in and 20 in, and a rear blade listed as 12 in for this model year.
Summary
For a 2001 Suburban, use 22-inch driver-side front blades and 20-inch passenger-side front blades, plus a 12-inch rear blade. If in doubt, verify through measurements or official documentation to accommodate any aftermarket substitutions.
