How to measure your belt size
Measure a belt you already wear, or take your waist and add two inches. Both give you the belt length that fastens comfortably on the middle hole.
There are two easy ways to find your belt size: measure a belt you already wear, or measure your waist where the belt sits and add a couple of inches. Both get you to the same number.
If you measure your body, wear the trousers you would wear with the belt so the tape sits where the belt will.
- Measure an existing belt. Lay a belt you like flat and measure from the fold at the buckle to the hole you fasten most often. That length is your belt size.
- Or measure your waist. Wrap a tape around your waist where the belt sits, over your trousers, keeping it level and comfortably snug.
- Add two inches. Add about two inches to your waist measurement to get the belt length that will fasten on the middle hole.
- Match to the chart. Find your figure in the chart and read the belt length in inches and centimetres and the EU number.

Measuring questions
How do I know my belt size?
Add about two inches to your trouser waist size, or measure an existing belt from the buckle fold to your usual hole. Match that length to the chart for US, UK inch and EU centimetre sizes.
Where should a belt fasten?
On the middle of five holes, so you can loosen or tighten by a hole either way. If it only reaches the last hole, the belt is too small.
