What is Regional Clothing Converter?
The same body doesn't wear the same size number in every country — a US size 8 is roughly a UK 10, a EU 40, and very different again on a Japanese or Chinese size chart. This converter maps general apparel sizes across five regional systems at once.
Pick your size band (XS through XXL) in any one region, and instantly see the equivalent labels used in the other four — useful before ordering from an overseas retailer or packing for a trip abroad.
This converter covers 5 regional sizing systems — US, EU, UK, Japan (JP), and China (CN) — across the standard XS–XXL apparel size range. Because exact sizing varies by brand and garment type, treat the results as a close estimate and check the retailer's own size chart for a precise fit.
When to Use This Calculator
- Shopping online from an international clothing retailer that lists sizes in an unfamiliar system.
- Traveling abroad and need to buy clothing using the local sizing system.
- Comparing your usual size across two brands based in different regions.
- Gifting clothing to someone in another country and need to translate their usual size.
- Studying or working with international sizing standards for a fashion or retail role.
- Double-checking an imported garment's tagged size against your home country's sizing before ordering.
Steps:
- Select your starting region (US, EU, UK, JP, or CN) from the first dropdown.
- Select your size within that region's sizing system.
- The equivalent size in each of the other four regions appears instantly.
- Compare all five regional sizes side by side before ordering or packing.
- Remember that exact fit varies by brand — use this as a starting reference, not a guarantee.
Formula
Apparel sizes don't convert by a single mathematical formula — each region defines its own size bands based on different body-measurement ranges and grading conventions. This converter uses a standard size-band lookup table (XS, S, M, L, XL, XXL) mapping each band to its typical US, EU, UK, JP, and CN label, based on common general-apparel sizing conventions. China's CN sizing additionally reflects height/chest in the format "height/chest+body-type" (e.g., 165/88A means 165 cm height, 88 cm chest, body type A).
Use Cases

- Understanding an imported garment's foreign size label relative to your home country's sizing.

- Covers the full standard size range from XS to XXL.
- Removes the guesswork when ordering clothing from an overseas retailer.
- Useful for travelers who need to buy clothing abroad in an unfamiliar sizing system.
- Shows all four other regions at once instead of one conversion at a time.
- Free, no registration required, works offline after the first load.
Pro Tips
- Always check the specific retailer's own size chart in centimeters or inches when it's available — it's more reliable than a general size-band conversion.
- When in doubt between two adjacent sizes, sizing up is usually safer for structured garments like jackets or trousers.
- Chinese CN sizes include a body-type letter (A, B, C) reflecting build, not just height and chest — check which letter matches your body type if shopping CN-labeled brands.
- Japanese sizing tends to run smaller than US/EU sizing for the same body measurements, not just a different label for the same fit.
- Use this converter as a starting point before ordering, then compare your own body measurements against the brand's chart in centimeters or inches for a precise fit.
- Keep in mind that this converter shows general apparel sizes, not category-specific charts like shoes, bras, or children's wear, which use entirely different scales.
Common Mistakes to Avoid
- Assuming size conversions are exact across every brand — general size-band tables are an approximation, not a guarantee.
- Ignoring the CN body-type letter (A, B, C) and only matching the height/chest numbers.
- Comparing a converted size label instead of comparing actual body measurements (in cm or inches) when a precise fit matters.
- Assuming JP and CN sizes follow the same scale just with different labels — they represent different typical body proportions, not just relabeled US/EU sizes.
- Forgetting that garment type (dress, jacket, jeans) can shift sizing even within the same brand and region.
- Treating this general apparel converter as accurate for shoes, bras, or children's clothing, which use separate, unrelated sizing systems.
