In practice
When you’d convert waist in centimeters to jeans waist
Measure your natural waist, or the waistband of a pair that fits, in centimeters, and read the W. 71 cm is W28, 76 cm is W30, 81 cm is W32 and 86 cm is W34.
Common mistake: Measuring over thick clothing or low on the hips. Jeans sit on the hip but the W is the waistband of the garment, so measure a pair that fits you flat and double it.
Flat across the waistband: 36 cm doubled is 72 cm, a W28; 38 cm doubled is 76 cm, a W30; 40.5 cm doubled is 81 cm, a W32. Between two sizes, take the larger for rigid denim and the smaller for stretch.
