Clothing Size Converter (XS–3XL ⇄ JP / US / UK / EU)
Cross-reference clothing sizes across Letter (XS / S / M / L / XL / XXL / 3XL), Japan (号 or cm), US, UK and EU. Switch between four charts (Men × Women × Tops × Bottoms) — tops use chest, bottoms use waist, both shown with the body measurement in cm. Useful when shopping at Amazon US / ASOS / H&M / Marks & Spencer from Japan or vice versa. Type a value to highlight the matching row. Tables are a composite of UNIQLO / MUJI / Marks & Spencer / H&M, with the usual 0.5–1 size brand variation (see FAQ). Runs entirely in your browser — no uploads.
How to use
1) Pick gender (Men / Women) and garment (Tops / Bottoms) with the radios. 2) The chart shows the full size table with Letter / Japan (号 or cm) / US / UK / EU / body measurement (cm). 3) Search by size — type a value (e.g. US 6 → '6') to highlight the matching row.
FAQ
- Why are Tops and Bottoms separate Modes?
- Tops are sized by chest, bottoms by waist — different base measurements. Country-specific number scales also map differently per garment, so a single chart would be confusing.
- Why do brands feel different at the same label?
- UNIQLO and MUJI (JP), Marks & Spencer (UK), H&M (EU) and GAP (US) all use slightly different actual measurements for an 'M', and Asian vs. Western fits differ in shoulder, sleeve and torso ratios. Always compare with the brand's own body-measurement chart in cm.
- What is Japanese 9 号?
- A traditional women's size grade: 9 号 ≈ bust 81–85 cm, equivalent to most M sizes. The full scale runs XS=5 / S=7 / M=9 / L=11 / XL=13. Men typically don't use 号 — they use letters (S/M/L/LL/3L) or chest/waist in cm.
- Why are US and UK women's sizes different?
- Historical divergence — UK ≈ US + 4 (UK 6 ≈ US 2). EU runs on yet another scale that roughly approximates body measurements in cm minus 30–40 (EU 36 ≈ 84 cm bust).
- Larger sizes than 3XL?
- We list up to 3XL. 4XL / 5XL continue with the same 1-size step, but actual measurements diverge a lot per brand at the high end. Always cross-check with the brand's own chart for 4XL+.
- Is my input uploaded?
- No. The search runs entirely inside your browser; nothing is sent over the network.
