Size recommendations are estimates, not guarantees. Always check the product size chart and return policy before buying. Clothing Size Calculator is independent and not affiliated with the listed brands unless stated otherwise.

Convert clothing sizes across regions

UK, US and EU labels do not always convert perfectly because brands use different fit models and product cuts. This converter gives you a practical estimate by combining size labels with measurement ranges.

Why size conversion is approximate

A conversion chart can translate labels, but it cannot guarantee fit. A UK 10, US 6 and EU 38 may not fit the same across every brand. Always check the product cut, fabric and size chart before buying.

Size converter FAQs

How do I convert UK sizes to US sizes?

Choose UK as your current region and US as the target region where available. The converter will show the closest label based on size chart data.

Are UK, US and EU sizes the same across brands?

No. Size labels can differ by brand, product type and fit. Use conversions as a guide, not a guarantee.

Does this converter work for shoes?

Yes. For shoes, foot length is usually the most important measurement.
