Measurement guide
Calculate your size from measurements
The calculator works best when you enter the measurements that matter most for the product you are buying. For jeans and trousers, waist, hips and inseam are usually most helpful. For tops, shirts, jackets and dresses, bust or chest and waist are important. For shoes, foot length is the key measurement.

Clothing size calculator FAQs
Which measurements do I need?
It depends on the product. Jeans and trousers usually need waist, hips and inseam. Tops, shirts and jackets usually need bust or chest, waist and sometimes shoulders or sleeve length. Shoes usually need foot length.
Can I use inches and pounds?
Yes. You can choose imperial units or metric units.
What if I only know some measurements?
You can still use the calculator with partial measurements. Adding more relevant measurements can improve the estimate.
What if I am between sizes?
If your measurements sit between sizes, check the product’s fit notes. Choose the smaller size for a closer fit and the larger size for a roomier fit.
