Belt Size Calculator
A belt needs to be longer than your waist, because the buckle and the hole you use take up some of its length. Enter your waist to see a starting belt size.

How it works
Take the waist measurement in inches and add two inches, then round to the nearest even inch, the way most belts are sized.
The answer is a starting length. Check a belt size chart before you buy, since sizes differ between makers.
Worked example
A waist of 34 in takes a belt about 36 in long.
Questions
Should I measure over my clothes?
Measure where you usually wear the belt, with the tape snug but not tight, and over the trousers you plan to wear it with.
Why add two inches?
The buckle and the hole you use take up length. Two inches is a common rule of thumb, not a standard.
Does the belt size match my trouser size?
Not always. Belts and trousers are sized on different scales, so the numbers can differ.
