Once you've learned that 개 is the all-purpose counter for objects, the next step is discovering that Korean would rather you be more specific. A book isn't ×한 개 — it's 한 권. A ticket isn't ×한 개 — it's 한 장. Korean has a working set of specialized counters, each tied not to what a thing means but to what shape or class it belongs to, and using the right one is a large part of sounding fluent rather than translated. This page teaches the everyday five — 장, 권, 병, 잔, 대 — and a quick fan-out of the next most useful ones. All of them take native numbers (한, 두, 세 …).
The counter encodes physical form, not meaning
Here's the mental shift for English speakers. English marks the shape of a thing only sporadically and optionally: a sheet of paper, a loaf of bread, a bar of soap, a head of lettuce. Most of the time we just say "two papers, three breads" and let context sort it out. Korean makes the shape-word obligatory and systematic. You choose the counter by asking what form does this object have — is it flat, is it bound, is it a bottle, is it a mechanical device? — not by what the object is for.
That's why a book (한 권) and a bottle of beer (한 병) take different counters even though both are "things you buy": one is a bound volume, the other is a bottle. Learn each counter as a shape category and the assignments stop feeling arbitrary.
장 — flat, thin sheets
장 counts anything flat and sheet-like: paper, tickets, photos, cards, boarding passes, sheets of seaweed (김), even a pizza.
종이 두 장만 주세요.
jong-i du jangman juseyo
Just give me two sheets of paper, please.
영화표 두 장 예매했어요.
yeonghwapyo du jang yemaehaesseoyo
I booked two movie tickets.
사진 몇 장만 찍어 주세요.
sajin myeot jangman jjigeo juseyo
Please take just a few photos (of us).
권 — bound volumes
권 counts bound reading material: books, notebooks, magazines, comic volumes. The thing that matters is that it's bound between covers — a stack of loose pages would be 장.
책 세 권을 다 읽었어요.
chaek se gwoneul da ilgeosseoyo
I finished reading all three books.
공책 두 권하고 펜 한 개 샀어요.
gongchaek du gwonhago pen han gae sasseoyo
I bought two notebooks and one pen.
병 — bottles
병 is the noun for "bottle" doing double duty as a counter. It counts liquid by the bottle you buy: beer, water, soju, wine, soda.
물 한 병만 사 올게요.
mul han byeongman sa olgeyo
I'll just grab one bottle of water.
잔 — cups and glasses of a drink
잔 counts a served portion of a drink — a cup of coffee, a glass of water, a shot of soju in the glass in front of you. This is the counter that pairs with drinking, whereas 병 pairs with buying.
커피 한 잔 주세요.
keopi han jan juseyo
One coffee, please.
맥주 두 병하고 콜라 한 잔 주세요.
maekju du byeonghago kolla han jan juseyo
Two bottles of beer and one glass of cola, please.
The 병/잔 split is worth pausing on: you order beer by the 병 (bottle) but drink it by the 잔 (glass). The two counters describe the same beer at different stages, and swapping them changes what you're actually asking for — see the mistakes below.
대 — machines and vehicles
대 counts things with an engine or mechanism: cars, bikes, computers, phones, TVs, cameras, airplanes, air conditioners. If it's a machine or a vehicle, it's 대.
주차장에 차가 두 대밖에 없어요.
juchajang-e chaga du daebakke eopseoyo
There are only two cars in the parking lot.
컴퓨터 한 대하고 자전거 세 대가 있어요.
keompyuteo han daehago jajeongeo se daega isseoyo
There's one computer and three bicycles.
The one-of-each reference table
| Counter | Class | "One _" |
|---|---|---|
| 장 | flat sheet | 종이 한 장 (a sheet of paper) |
| 권 | bound volume | 책 한 권 (a book) |
| 병 | bottle | 맥주 한 병 (a bottle of beer) |
| 잔 | served drink | 커피 한 잔 (a cup of coffee) |
| 대 | machine/vehicle | 차 한 대 (a car) |
A quick fan-out: five more you'll use constantly
Beyond the core five, a handful of counters come up daily. Each is keyed to a class:
- 켤레 — pairs of footwear or socks (shoes and socks come in twos): 신발 한 켤레, 양말 두 켤레.
- 그릇 — bowls of food (the noun "bowl" as a counter): 밥 한 그릇, 국수 두 그릇.
- 송이 — blossoms on a stem: 장미 한 송이, 꽃 세 송이.
- 벌 — sets/suits of clothing (an outfit counts as one unit): 옷 한 벌, 정장 두 벌.
- 채 — buildings/houses (large standing structures): 집 한 채, 건물 두 채.
신발 한 켤레 사고 싶어요.
sinbal han kyeolle sago sipeoyo
I want to buy a pair of shoes.
배고픈데 밥 한 그릇 더 주세요.
baegopeunde bap han geureut deo juseyo
I'm hungry — please give me one more bowl of rice.
어머니께 장미 한 송이를 선물했어요.
eomeonikke jangmi han song-ireul seonmulhaesseoyo
I gave my mother a single rose as a gift.
Common Mistakes
1. Flattening everything to 개. The single most common beginner tell is reaching for 개 when a specific counter exists. A book is 권, not ×개.
- ✗ 책 세 개 주세요.
- ✓ 책 세 권 주세요. — chaek se gwon juseyo — "Give me three books."
2. Confusing 병 (bottle you buy) with 잔 (glass you drink). They're not interchangeable — each describes a different thing.
- If you order 맥주 한 잔, you get one glass poured (often draft). If you order 맥주 한 병, you get a whole bottle. Saying 잔 when you wanted a bottle gets you a fraction of what you expected.
맥주 한 병 시켰는데 잔이 없어요.
maekju han byeong sikyeonneunde jani eopseoyo
I ordered a bottle of beer but there's no glass.
3. Using 개 for a machine instead of 대. Cars, computers, and phones are 대.
- ✗ 차 두 개 있어요.
- ✓ 차 두 대 있어요. — cha du dae isseoyo — "There are two cars."
4. The Sino-number slip. These counters all take native numbers.
- ✗ 종이 삼 장
- ✓ 종이 세 장 — jong-i se jang — "three sheets of paper"
5. Counting flat and bound the same way. Loose paper is 장 (a sheet); a bound book is 권 (a volume). Don't mix them.
- ✗ 잡지 두 장 (a magazine is bound)
- ✓ 잡지 두 권 — japji du gwon — "two magazines"
Key Takeaways
- Korean prefers a shape-specific counter over the generic 개: 장 (flat), 권 (bound), 병 (bottle), 잔 (served drink), 대 (machine/vehicle).
- Choose the counter by the object's physical form, not its meaning — that's why a book (권) and a beer bottle (병) differ.
- 병 vs 잔 is a buying-vs-drinking distinction: order beer by the 병, drink it by the 잔.
- All these counters take native numbers in bound form: 한 장, 두 권, 세 병 — never ×삼 장.
- High-value extras: 켤레 (pairs), 그릇 (bowls), 송이 (blossoms), 벌 (outfits), 채 (buildings).

- 개: The General Counter for ThingsTOPIK 1 — 개 is Korean's default all-purpose counter for inanimate objects, taking native numbers — 한 개, 두 개, 세 개. When you don't know a specialized counter, 개 is the safe fallback — but never for people (명) or animals (마리).
- Counters (Measure Words): Why You Can't Count Bare NounsTOPIK 1 — Korean can't quantify a noun directly — it inserts a counter (분류사), like English 'two sheets of paper' but obligatorily and for everything. The frame is Noun + Number + Counter: 사과 세 개, 학생 네 명, 커피 두 잔.
- Native or Sino? Which Counter Takes WhichTOPIK 2 — The master rule for Korea's two number systems: if you could point and tally the things, use native numbers (개, 명, 마리, 시, 살); if it's an abstract unit, measure, rank, or calendar/clock unit, use Sino (분, 원, 년, 층, 인분). Plus the clash cases that break learners.
- Word Order and Spacing: 사과 세 개TOPIK 1 — The counted phrase is Noun + Number + Counter — 사과 세 개, 학생 네 명 — the noun leads and the quantity trails, the reverse of English 'three apples.' Plus the two mechanics: the number takes its determiner form (세, 두) and a space goes between number and counter (세 개, never ×세개).
