How to use the Clothing Size Converter
- Choose Women or Men.
- Pick the garment type: tops, jeans or shoes. A t-shirt M and jeans FR 38 do not use the same chart.
- Choose the source country or format, for example US by default, Letter for S/M/L, or FR when you know a French store size.
- Choose the target country or format, for example EU, UK, FR, IT, DE, ES or JP.
- Enter a measurement in centimetres when you know your bust, chest, waist, hip, neck or foot length and want the closest chart matches.
- Use the full reference chart below to spot-check the result or to compare nearby sizes before ordering.
The major international size systems
Clothing and shoe sizes are not standardized worldwide, which makes online shopping confusing. The main systems in this converter are:
- US, uses numbers (0, 2, 4 ... for women; chest in inches for men) plus letters (XS, S, M, L, XL, XXL).
- UK, close to US but typically four points higher for women (US 8 ≈ UK 12). Shoes are usually one to one and a half sizes lower than US.
- FR, French store sizing. Women's clothing and jeans commonly use 34, 36, 38, 40 and higher; men's tops can use jacket/chest numbers such as 42, 44, 46, or letter sizes for t-shirts.
- EU, European reference sizing. It can match FR for some categories such as shoes, but it is shown separately to avoid hiding country differences.
- IT / DE / ES, country-specific labels often used by Italian, German and Spanish retailers. Some categories match another European scale, but the tool keeps them visible for shopping clarity.
- JP / Mondopoint, Japan uses centimetres of foot length for shoes, and chest centimetres for clothing. It is the most physically meaningful scale.
Tips for ordering the right size online
- Always measure yourself, a soft tape measure is ideal. Record bust, waist, hip, inseam and foot length once for life.
- Compare to the brand's chart, even within the EU, brands cut differently. Use the brand's chart and our tool to pick the closest match.
- Beware of vanity sizing, luxury brands sometimes label garments smaller than reality. Older Levi's jeans run larger than newer cuts.
- Check returns policy, when in doubt, order two sizes and return the one that does not fit.
Frequently asked questions
Why are women's UK sizes so much higher than US?
Women's UK sizes look higher because the two systems evolved with different commercial offsets, not because the garment is physically much larger. A UK 12 dress is usually close to a US 8, while a UK 8 is usually close to a US 4. The converter keeps both labels visible so you can compare the row, then use the bust, waist or hip reference to check the actual fit.
Why do men's French tops start at 42?
For men's tops, numeric French and European sizes often follow jacket, shirt or chest-based sizing, so the range commonly starts around FR 42 or FR 44. That does not mean French t-shirts start at 42 in every shop. Casual t-shirts, hoodies and sportswear often use letters such as S, M, L or XL, so the converter shows both numeric and letter references when they are useful.
What does Mondopoint mean?
Mondopoint is an international shoe sizing method based on foot length, normally shown in millimetres or centimetres. Japan and many athletic brands use the length part of that idea, which is why JP shoe sizes look like 24.5 or 27.0. It is often more reliable than country labels because it starts from the physical foot measurement rather than a national numbering tradition.
Why does my number differ from a friend's, even at the same height?
Garments are designed around body proportions, not height alone. Two people can be the same height but have different bust, chest, waist, hip, inseam or shoulder measurements, which changes the best size. Use the converted country label as a fast reference, then compare the measurement row with your own body. To convert measurements between centimetres and inches, use the Unit Converter.
Should I size up when I am between two sizes?
Usually yes for fitted clothing, non-stretch denim, structured jackets and shoes worn with thick socks, especially when the brand is known to run small. For loose cuts, stretchy fabrics or intentionally oversized styles, the lower size may feel better. The closest match in this tool is a starting point, so check the measurement difference, product reviews and return policy before making the final choice.
Is my size information saved or uploaded?
No size information is uploaded because the converter runs in your browser after the page loads. Your current choices and temporary measurements are kept only for this tab so the tool does not reset while you compare rows. Closing the tab clears those tool values. The site does not need an account, a server calculation or a stored shopping history to convert sizes. Your data is never used to train AI models or improve machine learning systems.
What sources are used for measurements?
Clothing size labels are commercial references and can vary by brand, cut, country and product line. The conversion rows are cross-checked against public retailer and competitor size guides, then paired with standard body-measurement principles from ISO 8559-1:2017. Centimetre and inch references use official SI length definitions from NIST. For final purchases, always compare the result with the retailer's own chart.
