How to Measure
Finding the right belt size is simple. Whether you’re shopping for men’s or women’s belts, the process is the same:
Option 1: Measure an existing belt
Measure from the inner edge of the buckle to the hole you use most frequently which should be the middle hole. This length will correspond to your waist size.
Note: The size printed on the belt may not accurately reflect its true measurement.

Option 2: Measure your waist
Use a tape measure around the part of your waist where you normally wear your trousers (high-waisted, standard, or low-rise)

Choosing the Right Size
- If your measurement falls between two sizes, we recommend selecting the larger size.
- All Robert Charles belts are sized from the base of the buckle to the third (central) hole, which is considered the ideal fastening point.
- Most of our belts (with the exception of elastic styles) can be easily shortened for a precise fit.
- If in doubt, we suggest ordering a size up and adjusting as needed.
