Belt Sizes in CM: Conversion Chart and How to Measure
· Trevor Wing
To convert a belt size from inches to centimeters, multiply by 2.54. A size 36 belt is about 91 cm. A 110 cm belt is about a size 43, which suits a pant waist around 41. Brands label differently, so confirm what the number measures before you order.
The short version
- 1 inch = 2.54 cm.
- Belt size is usually your pant size plus 2 inches.
- 100 cm is about a size 39. 110 cm is about 43. 115 cm is about 45.
- Some brands list belt length, some list waist. Check which.
- Measure a belt you already own for the surest answer.

Belt size is about 2 inches larger than the pant size. That rule of thumb works, though it is only a starting point.
What 100, 110 and 115 cm mean
- 100 cm is about 39 inches. A belt size 39, so a pant waist near 37.
- 110 cm is about 43 inches, which suits a pant waist near 41.
- 115 cm is about 45 inches, which suits a pant waist near 43.
If the listing sizes by waist instead of belt length, the number is already your waist. Read the chart on the listing before you buy.
How to measure
- Best: lay a belt that fits you flat. Measure from where the strap folds at the buckle to the hole you use. That is the belt size.
- Second best: measure your waist where the belt sits and add 2 inches. Use a flexible tape, not a rigid one.
- Convert the result with the chart.

Why brands differ
There is no single world standard. Some list the total strap length. Some list the center hole length. Some list the waist. That is why a chart is worth reading and why two 100 cm belts can fit differently.
Try the belt on before you exchange it. That is the moment to fix the size. People often order a size that is too large and never try it on.
Length also needs a fit check
A belt that is the right size also needs the right tail. See how long should a belt be.
