BELTS SIZE GUIDE
There are two methods to measure your waist or a belt:
- Take a tape measure and measure at the point where I typically wear my belt.
- Alternatively, measure a belt that you already wear by measuring from the end of the buckle to the most frequently used hole, which is usually the middle hole.
The most reliable solution is to measure your waistline.
