Clothing Size Converter for US, UK, EU, JP & KR
The Clothing Size Converter turns a size you already know into its equivalent across US, UK, EU, JP (Japan), and KR (Korea) standards, so shopping from international brands stops being a guessing game. It is built for anyone buying tops, bottoms, or dresses online — for women or men — who wants the right fit the first time.
Each chart pairs the label sizes with real body measurements in centimeters, so you can match by your size or by your bust, waist, hips, and chest. Because every country built its own system, a US Women's 6 lands near a UK 10 and EU 38, while Asian sizing (JP, KR) tends to run smaller — this tool lines all five up side by side so you never have to convert in your head.

Frequently Asked Questions
How do I convert US clothing sizes to UK or EU?
Pick your gender and garment type, then use Quick Convert: set From to US, choose your size, and the table highlights the matching UK, EU, JP, and KR equivalents in the same row. For example, a US Women's 6 lines up with a UK 10 and an EU 38.
Are these size conversions exact?
The conversions are approximate guidelines based on common international standards. Real sizing varies between brands, manufacturers, and even product lines within the same label, so always check a specific brand's size guide when you can — and cross-reference the centimeter measurement columns for the closest match.
Why do Asian sizes (JP, KR) seem smaller?
Japanese and Korean systems are calibrated to different body proportions, so a "Medium" in JP or KR usually fits a smaller frame than a US or EU Medium. This is exactly why matching against the body measurements in centimeters gives the most reliable result.
How should I measure myself for the best fit?
Use a flexible tape over light clothing. Measure bust/chest around the fullest part of the chest, waist around the narrowest part of the natural waistline, and hips around the fullest part of the hips. Compare those numbers (in cm) with the measurement columns in the chart.
What if I'm between two sizes?
When your measurements fall between two sizes, it is generally safer to size up for structured garments like jackets and dress shirts. For stretchy fabrics, the smaller size often works fine.
How do I convert women's versus men's sizes?
Women's and men's sizing use separate charts, so switch the gender toggle first. Women's covers tops, bottoms, and dresses, while men's covers tops and bottoms — each with its own set of US, UK, EU, JP, and KR equivalents.
Does this cover children's clothing sizes?
No. This converter focuses on adult women's and men's clothing. Children's sizing follows different standards (often by age or height) and needs its own conversion charts.
