Clothing Size Converter
Convert men's and women's clothing sizes between US, UK, and EU sizing.
How it works
This converter looks up your size in a standard sizing chart to translate men's or women's clothing sizes between the US, UK, and EU sizing systems, which each use different numbering conventions for the same actual garment dimensions.
US and UK sizing for women's clothing typically differ by a consistent offset — a US size is commonly about 4 sizes smaller than the equivalent UK size (a US 8 is roughly a UK 12), though this offset can shift slightly depending on the specific garment category and brand.
EU sizing uses a different numbering system entirely, often based on body measurements in centimeters rather than the more arbitrary US/UK numbering — EU women's sizes commonly run from around 32-34 (equivalent to a US 0-2) up through larger sizes, with roughly a 2-number EU step corresponding to one US/UK size step.
Men's sizing tends to be somewhat more standardized across regions for certain categories (like shirts sized by neck measurement in inches or centimeters, or pants sized by waist measurement), but jacket, suit, and general apparel sizing still varies by region and follows the same US/UK/EU conversion pattern as women's wear.
These conversions are necessarily approximate rather than exact, because clothing sizing isn't governed by a single universal standard the way, say, length units are — different brands and manufacturers use their own size charts, cut garments differently, and "vanity sizing" trends (brands sizing generously to make customers feel smaller) have shifted numbering over time within regions too.
For online shopping across international sites, checking a specific brand's own size chart (usually based on body measurements like bust, waist, and hip in inches or centimeters) alongside a general conversion like this one gives the most reliable result, since brand-specific variation is often larger than the general regional conversion difference.
Children's clothing sizing adds yet another layer of complexity, often based on age ranges or height/weight combinations rather than the adult numbering conventions this converter focuses on — a reminder that "clothing size" isn't one universal system but several overlapping ones depending on the garment category and target age group.
Are these sizes exact?
No — sizing varies between brands and manufacturers. Use this as a general starting reference, not a guarantee of fit.
How much smaller is a US women's size than the equivalent UK size?
Typically about 4 sizes smaller — a US size 8 is roughly equivalent to a UK size 12 — though this offset can vary slightly by garment type and brand.
Why does EU sizing use different numbers than US or UK?
EU sizing is generally based more directly on body measurements in centimeters, producing a different numbering scale than the more historically arbitrary US and UK size numbers.
Is men's clothing sizing more standardized than women's?
Somewhat, for certain categories — shirts sized by neck measurement and pants sized by waist measurement use fairly consistent numbers across regions, but general apparel sizing still varies similarly to women's wear.
Why do two garments with the same labeled size sometimes fit differently?
Different brands and manufacturers use their own size charts and cut garments differently, so the same nominal size can correspond to different actual measurements between brands.
What is 'vanity sizing'?
A trend where brands label garments with smaller size numbers than their actual measurements would traditionally suggest, to appeal to customers — this has shifted size numbering within regions over time, adding to sizing inconsistency.
What's the most reliable way to size clothing when shopping internationally?
Check the specific brand's own size chart based on body measurements (bust, waist, hip) alongside a general regional conversion, since brand-specific variation is often larger than the general conversion difference.
Does this converter account for different garment categories (dresses vs. pants vs. tops)?
It provides general US/UK/EU size equivalents; for the most accurate fit, cross-check against a brand's specific chart for that particular garment category.
Does this converter cover children's clothing sizes?
No — this focuses on standard adult US/UK/EU sizing; children's clothing typically uses separate age-range or height/weight-based sizing systems.
Why is clothing sizing so much less standardized than something like shoe length?
Clothing fit depends on multiple body dimensions (bust, waist, hip, and more) and garment cut simultaneously, giving brands much more room for variation than a single-dimension measurement would allow.
