How Belt Size Conversion Works
Belt sizes are based on your waist measurement. Different regions use different numbering systems, but they all correspond to the same physical waist circumference. Our converter maps between these systems using standardized measurements.
The most universal measurement is the waist circumference in centimeters or inches. If you know your waist measurement, you can find your size in any system using our converter above.

Important Notes
- •Belt size is not the same as pants size. Belts are typically 2 inches larger than your trouser waist size.
- •Sizes can vary between manufacturers. When in doubt, measure your waist or an existing belt.
- •EU sizes are rounded to the nearest 5 cm. Actual measurements may fall between listed EU sizes.
