Belt Size for a 40 Inch Waist (Inches, cm, Letter)
For a 40-inch trouser waist, buy a size 42 belt: about 105 cm in EU sizing, and usually XL on letter-sized belts. Belts are sized about 2 inches above the trouser waist, so the buckle closes on the middle hole.
| Trouser waist | Belt size | Belt (EU cm) | Letter |
|---|---|---|---|
| 40 in | 42 in | 105 cm | XL |
Good to know
- Belt size is measured from the buckle fold to the middle hole. Your old belt's middle hole, measured with a tape, gives the same number.
