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.
