Clothing Size Converter - US, UK, EU and International Sizes

A clothing size converter compares apparel size labels across common systems, including US, UK, EU, and international letter sizes. It helps you translate the size printed on one chart into the closest label on another chart.

The tool is most useful when shopping from another country, buying gifts, checking vintage labels, or comparing a marketplace listing with your usual size. It also shows body measurement ranges so the label is not the only clue.

• • Convert women's, men's, and kids' clothing labels.
• • Compare US, UK, EU, and international sizes in one table.
• • Review fit notes before relying on a size label.

To compare footwear labels too, use our Shoe Size Converter for US, UK, EU, and CM shoe sizes.

This US to UK clothing size converter uses ordered lookup tables for each apparel group. When you choose a source system and size, the calculator finds the matching row and returns the equivalent labels from the same row.

Clothing sizing is different from exact unit conversion. The ISO 8559-1:2017 standard focuses on body measurement designation, which is why measurements are more reliable than labels alone.

To switch between inches and centimeters while checking a retailer chart, open our Height Converter for quick measurement comparisons.

An international clothing size conversion chart is a guide, not a promise. Systems may share similar numbers while measuring different things, so choose the correct apparel group before interpreting the result.

The ISO 8559-2:2017 sizing reference highlights primary and secondary body dimensions, which explains why charts often ask for more than one measurement.

When a chart lists fractional inches, try our Inches to Fraction Calculator to read tape-measure values cleanly.

Use this EU to US clothing size converter when you know one label and need the closest equivalent in another region. Stay within the same apparel group because men's, women's, and kids' systems are not interchangeable.

If waist and hip measurements are part of your fit check, use the Waist-to-Hip Ratio Calculator for a separate body-measurement comparison.

A clothing size converter by measurements helps reduce guesswork before checkout. It is especially useful when a store lists only one regional chart or when a secondhand listing uses unfamiliar labels.

• • Compare international labels before ordering from overseas stores.
• • Check whether a gift size is likely to match the recipient's usual size.
• • Reduce avoidable returns caused by reading the wrong regional chart.
• • Use measurement ranges as a second check when labels are ambiguous.

For another everyday sizing workflow, the Recipe Serving Size Scaler helps resize quantities when a simple label or serving count is not enough.

Men's shirt size conversion US UK EU charts often look cleaner than women's fashion charts because many men's sizes are tied to chest or collar measurements. Even then, a slim-fit shirt and relaxed shirt can feel different at the same label.

For measurement-unit context, the NIST SI Units resource explains the metric system used by many international charts.

To convert body measurements between unit systems, use our Length Converter before comparing the final size chart.
