Clothing Size Converter
Choose men's or women's, tops or bottoms, and a size from XS to XXL, and this tool shows the equivalent US, UK, and EU size ranges as a general sizing reference.
How It Works
Online shopping is the main reason this kind of conversion comes up. A shopper browsing an overseas retailer's website often only has their own country's size to go on, and guessing wrong means a return or exchange across international shipping. It is also handy while traveling, when trying on clothes labeled in a system you are not used to, or when reading a size chart shared by a friend or family member abroad.
This tool looks up your chosen international letter size (XS through XXL) in a general reference table and shows the roughly equivalent US, UK, and EU size ranges for that category of garment.
Clothing sizing varies significantly by brand. This is a general reference guide, not a brand-specific size chart.

Frequently Asked Questions
Is there one universal clothing size standard?
No. Clothing sizing varies significantly by brand, country, and even by garment cut within the same brand. This chart is a general reference guide, not a brand-specific size chart.
Why do men's and women's size charts look so different?
Men's clothing is often sized by body measurements in inches (like chest or waist size), while women's clothing commonly uses a separate numbered scale. Both are mapped to the same XS to XXL letter sizes here for easy comparison.
Should I size up or down between brands?
If a brand runs small or large, check that brand's own size chart and customer reviews when available. This general chart is a helpful starting point, not a guarantee of fit for any specific label.
Do bottoms and tops use the same size scale?
They are shown on the same XS to XXL scale here for simplicity, but a person's top size and bottom size do not always match, since body proportions vary.
Why do US, UK, and EU sizes differ so much for the same garment?
Each region historically built its own sizing standard around different body measurement surveys and labeling conventions, so the same physical size ends up with a different number depending on where the clothing was designed and sold.
What should I do if I am between two sizes?
Consider the fit you want. Sizing up usually gives a more relaxed, comfortable fit, while sizing down gives a closer, more fitted look. Checking the brand's specific measurements against your own body measurements is the most reliable approach when it matters.
