Expect ±1 size variation by brand and country. The same mm can fit differently by width and heel, and women's 44/55/66 labels date from a 1980s standard body, so actual measurements vary by brand. Check the brand's own size chart before ordering.

What this tool does
The Korean size converter maps Korean clothing and shoe sizes to US, EU, UK, and Japanese sizes at a glance. Shoes use mm (foot length); clothing uses chest-cm-based Korean labels (men 90/95/100, women 44/55/66) compared to international sizes. Reduce sizing mistakes when shopping K-fashion overseas or on Korean shopping sites.

Size basis
Shoes (mondopoint): Korea and Japan use foot length in mm. 260 = 26.0 cm. US ≈ (mm−180)/5; EU ≈ mm × 1.5 + 2 (approx). Men's 260 ≈ US 8 / EU 41 / UK 7.5 Women's 240 ≈ US 7 / EU 37.5 / UK 4.5 Clothing (chest cm based): Men's 90(S)=90cm chest, 95(M)=95cm, 100(L)=100cm Women's 44(XS), 55(S), 66(M), 77(L), 88(XL) traditional labels → mapped to US/EU standard labels
Real examples
Example 1: Men's shoe 270 → US 9
Korean 270mm = 27.0cm = US 9 / EU 42.5 / UK 8.5 / JP 27.0. Pick US 9 when buying Nike or Adidas.
Example 2: Women's clothing 55 → US 4
Korean women's 55 = S = 85cm chest ≈ US 4 / EU 36 / UK 8. Choose S or US 4 on Zara or H&M.
Example 3: Men's clothing 100 → L
Korean men's 100 = 100cm chest = US L / EU 50 / UK 40. American brand L or EU 50.
Frequently asked questions
Why are Korean shoe sizes numbers like 250, 260?
They are foot length in mm (mondopoint). 250 = 25.0 cm foot length. Japan uses the same (in cm). It's the most intuitive measure of the foot, used across Korea and Japan.
What do women's 44/55/66 mean?
Traditional labels from 1980s standard body measurements. 55 is the standard (S), 44 is smaller (XS), and 66/77/88 are larger. The numbers themselves don't carry literal meaning — they're entrenched labels.
Brands differ — is this chart accurate?
This chart uses KS standards + international references as general values. Actual fit varies ±1 size by brand and cut (slim/oversized). Cross-check the brand's cm measurements when possible.
Are US shoe sizes different for men and women?
Yes. For the same foot length, US labels differ by gender (women ~1.5 larger). This chart separates men and women, so use the right category. EU is unisex.
Are children's sizes included?
No, this chart is for adults. Children's sizing uses a separate system (foot mm is the same, but clothing is height/age-based).
Any tips for sizing up/down when importing?
Shoes are usually true to size, but US brands sometimes run large — size down 0.5 for narrow feet. Clothing from US/EU runs larger than Asian fit, so consider sizing down. Reviews and cm measurements are safest.
