Quick answer
Measure your waist where your trousers sit, then convert to inches. Men's jeans and trousers use that number rounded to an even size: an 84 cm (33-inch) waist is size 34. Women's jeans sizes also follow the waist in inches, so a 76 cm waist is size 30. Your belt size is your trouser size plus 2 inches.
How to measure
- Measure around your waist where your trousers or jeans usually sit.
- Keep the tape snug but not tight, and breathe out normally.
- Read your sizes for each type of clothing.
