Lay the belt flat on a straight surface
Measure from the buckle fold or buckle prong start to the hole you use most often
If there is no buckle, measure the full length from end to end
Use a flexible measuring tape or a ruler
Record the measurement in inches or centimeters
Compare the measurement to the belt size chart if needed
For a replacement belt, measure an existing belt that fits well
For a waist fit, measure around the waist where the belt will be worn
Choose a belt size that is slightly longer than the waist measurement
