Jeans Size Calculator

What this calculator does

Jeans are often sold as waist by leg length, especially in denim sizing. This calculator converts centimetre measurements into approximate W and L sizes.

Formula used

Waist and inseam measurements are converted from centimetres to inches and rounded to practical jeans sizes. Fit preference adds a note about sizing up or down.

How to read the result

Denim stretch, rise and cut change fit. Use the result as a first size, then check garment measurements where available.

Assumptions

• Uses body measurements in centimetres.
• Returns approximate inch-based W and L sizing.
• Does not replace brand-specific garment charts.
