Option 1: Most Accurate Way
Option 2: If you Don't have a Belt to Measure:
Pick a pair of pants that fit well and add 2 inches to the waist size on the tag to get your belt size. Example: If you wear a 36 waist pants... order a 38" belt size. If you have multiple size pants we would recommend measuring a current belt per option 1's directions. FYI....Jeans are normally sized large. We recommend using this method with dress slacks or khakis. It's common for size 36 men to fit in size 34 jeans.
