Example: Waist 32.4", Hip 40", Inseam 31.6" → Men’s W32/L32. Closest women’s size: US 12 (waist 31", hip 41").

Frequently Asked Questions
Why don’t my measurements match the size I usually wear?
Many brands use vanity sizing. This calculator gives a measurement-based baseline; adjust for brand preferences and fabric stretch.
How can I convert to EU or UK jeans sizes?
Convert the waist measurement to centimeters (multiply by 2.54) and consult brand charts. Many EU labels use waist measurement directly.
What if my hips are much wider than my waist?
Try curvy-fit jeans. You may need to size up for hip room and tailor the waist for a snug fit.
Can I use this for children’s jeans?
This calculator is optimized for adult sizing. Children’s jeans use age-based and height-based charts.
