Shoe sizes in Korea

Shoes in Korea are labeled by foot length in millimeters, in 5 mm steps: 230, 235, 240 and so on. It is the most logical system in the world — measure your foot from heel to longest toe and you have your size. Most women wear between 225 and 250, most men between 255 and 280.

In a shop, the staff may ask 사이즈가 어떻게 되세요? (saijeuga eotteoke doeseyo?) (What size are you?) or 발 사이즈가 몇이에요? (bal saijeuga myeochieyo?). Answer with the number: 이백사십이요 (ibaeksasibiyo) (240). Numbers for sizes are Sino-Korean.

Clothing sizes in Korea

Korea uses three kinds of clothing labels. Women's clothes often use 44, 55, 66, 77, 88 (from XS to XL). Both women's and men's clothes use chest sizes in centimeters: 85, 90, 95, 100, 105, 110. And many brands simply use S, M, L or 프리 (free size). Korean fits tend to be slimmer than US fits, so many visitors go one size up.

Pants are labeled by waist, in inches (26, 28, 30…) or centimeters (66, 71, 76…). Try things on when you can: 입어 봐도 돼요? (ibeo bwado dwaeyo?) (Can I try it on?).

Ring sizes and cosmetics volume

Rings are sized by number + 호: 12호 (12ho). Couple rings are popular in Korea, and many jewelry shops will resize a ring for you. Korean cosmetics are labeled in milliliters (ml) and grams (g): a 50 ml cream is 1.69 fl oz, and carry-on liquids on flights must be 100 ml (3.4 fl oz) or less per container.

Frequently asked questions

How do Korean shoe sizes work?

Korean shoe sizes are your foot length in millimeters: 250 means a 25 cm foot. A women's US 7 is about 240, and a men's US 9 is about 270. Japan uses the same scale in centimeters (24 = 240).

What does size 55 or 66 mean in Korean clothes?

Women's clothes in Korea are often labeled 44, 55, 66, 77 and 88. 55 is roughly S and 66 roughly M. Many shops also use chest sizes (85, 90, 95, 100), and men's tops are almost always labeled this way: 95 is M, 100 is L, 105 is XL.

What is “free size” in Korea?

프리 사이즈 (peuri saijeu) (often written F or FREE) means one size, usually cut to fit about Korean 55–66 (S–M). Loose items like sweaters fit many people; fitted items may run small.

How do I ask for a size in Korean?

Say the size + 사이즈 있어요?: 240 사이즈 있어요? (240 saijeu isseoyo?) (Do you have 240?). Shoe sizes are read with Sino-Korean numbers: 240 is 이백사십. To ask for a bigger or smaller one: 더 큰 거 있어요? (deo keun geo isseoyo?) / 더 작은 거 있어요? (deo jageun geo isseoyo?).

What is my ring size in Korea?

Korean ring sizes are numbers followed by 호 (ho), on almost the same scale as Japan: size 12 is about 52 mm around the inside, close to US 6. Use the Rings tab, or measure the inside of a ring that fits you.
