Waist Measurement Converter
Convert waist measurements between inches and centimetres. Distinguish body circumference from flat garment width before choosing shorts.
Convert inches to centimetres by multiplying by exactly 2.54, or convert centimetres to inches by dividing by 2.54. For example, 33 inches equals 83.82 centimetres. Results are displayed to two decimal places. Unit conversion does not change a body measurement into a garment measurement or assign a shorts size.
Enter your body-waist circumference to begin.
Use body circumference, not the width of shorts laid flat. This does not determine hip fit, garment length or competition eligibility.
From measurement to your pair
- Measure your waist with a flexible tape and record the unit.
- Enter the circumference and choose its unit to see the conversion.
- Review the exact product guide, then choose a design or ask us about fit.

No. Conversion changes the unit only. Use the relevant product chart or our size finder to compare a body-waist target.
