In English, you say “three books” or “two cats” — the number goes right before the noun. In Korean, it’s not that simple. Korean uses counters (also called classifiers or counting units) — special words that go between the number and the noun to describe what type of thing you’re counting. And there are different counters for people, animals, flat things, round things, drinks, books, and more.
This is one of the trickiest parts of Korean for English speakers, but the good news is that a handful of common Korean counters cover the vast majority of everyday situations.
How Do Korean Counters Work?
Korean counters follow the pattern: Noun + Number + Counter. For example, “three books” is 책 세 권 (chaek se gwon) — literally “book three [book-counter].” The counter 권 specifically means “volumes/books,” and you can’t use it for anything else.
Important rule: counters almost always use native Korean numbers (하나, 둘, 셋…), not Sino-Korean numbers (일, 이, 삼…). If you need a refresher on the two number systems, the Korean numbers 1-100 guide breaks down exactly when to use which.
One more thing: when native Korean numbers 1-4 appear before a counter, they change form:
- 하나 → 한 (han)
- 둘 → 두 (du)
- 셋 → 세 (se)
- 넷 → 네 (ne)
So “one person” is 한 명 (han myeong), not 하나 명.
The 10 Most Common Korean Counters
Master these ten and you’ll be able to count almost everything you encounter in daily Korean life:
1. 개 (gae) — General counter for things/objects
This is the all-purpose counter. When you don’t know the specific counter for something, 개 usually works. Think of it as the “default” counter.
- 사과 두 개 (sagwa du gae) — two apples
- 달걀 세 개 (dalgyal se gae) — three eggs
2. 명 (myeong) — People (polite)
- 세 명 (se myeong) — three people
- 학생 다섯 명 (haksaeng daseot myeong) — five students
3. 마리 (mari) — Animals
- 고양이 한 마리 (goyangi han mari) — one cat
- 개 두 마리 (gae du mari) — two dogs
4. 권 (gwon) — Books/volumes
- 책 한 권 (chaek han gwon) — one book
5. 잔 (jan) — Cups/glasses of drinks
- 커피 두 잔 (keopi du jan) — two cups of coffee
- 맥주 세 잔 (maekju se jan) — three glasses of beer
6. 병 (byeong) — Bottles
- 물 한 병 (mul han byeong) — one bottle of water
7. 장 (jang) — Flat/thin objects (paper, tickets, photos)
- 종이 세 장 (jongi se jang) — three sheets of paper
- 사진 한 장 (sajin han jang) — one photo
8. 대 (dae) — Machines and vehicles
- 차 한 대 (cha han dae) — one car
- 컴퓨터 두 대 (keompyuteo du dae) — two computers
9. 벌 (beol) — Sets of clothing
- 옷 한 벌 (ot han beol) — one set/outfit of clothes
10. 번 (beon) — Times/occurrences
- 세 번 (se beon) — three times
- 한 번 더 (han beon deo) — one more time
Korean Counters for Food and Restaurants
If you’re ordering food in Korean, these additional counters come up constantly:
- 그릇 (geureut) — bowls of food: 비빔밥 한 그릇 (bibimbap han geureut) — one bowl of bibimbap
- 인분 (inbun) — servings/portions: 삼겹살 이 인분 (samgyeopsal i inbun) — two servings of pork belly
- 조각 (jogak) — pieces/slices: 피자 세 조각 (pija se jogak) — three slices of pizza
Ordering at a Korean restaurant typically sounds like: 비빔밥 두 그릇 주세요 (bibimbap du geureut juseyo) — “Two bowls of bibimbap, please.”
What Happens If You Use the Wrong Counter?
Nothing terrible. Koreans will understand you perfectly even if you use 개 (the general counter) for everything. Using the wrong counter sounds a bit off — like saying “three pieces of dogs” in English — but it doesn’t cause confusion. As a beginner, it’s much better to speak with the wrong counter than to freeze up trying to remember the right one.
That said, getting counters right is one of those details that makes your Korean sound noticeably more natural. Start with 개, 명, and 마리, and add more as they come up in your studies.
