How to Measure Your Belt Size

Most of our belts are sized from the Buckle Fold to the Middle Hole. A 36” belt will have a middle hole at 36” and two holes on either side of the center spaced 1” apart each. A 36” belt can be worn as small as 34” and as big as 38”.

There are several options to determine your ideal belt size.

The ideal way is to measure your waist through your belt loops. This measurement is the size of belt you should purchase (i.e. if you have a 34” measurement, order a 34” belt).

How To Measure Your Belt Size

An alternative option is to measure your old belt from the  Buckle Fold to the Hole you use. If your belt measures 38” from buckle fold to the hole you use most; then order a 38” belt. This will give you a belt with 2 holes either side of the hole you use most.
