Korean Counter 장: How to Count flat objects/sheets

Use native Korean numbers with 장 to count paper, tickets, photos.

The Rule

장 is the counter for flat objects/sheets: paper, tickets, photos. In Korean, you can't just say a number + noun. You MUST use a counter word between them. This is like English "two SHEETS of paper" or "three CUPS of coffee" — except Korean does this for EVERYTHING. Even "three apples" needs a counter: 사과 세 개.

Why English Speakers Get It Wrong

English only uses counters for uncountable nouns ("a glass of water", "a piece of cake"). Korean uses counters for ALL nouns — even ones English counts directly. The second trap: Korean has TWO number systems. 장 uses native Korean (하나, 둘, 셋...) numbers. Using the wrong system is a common mistake that sounds immediately wrong to Korean ears.

How It Works

Pattern: Noun + Number + 장 Native Korean numbers (shortened before counters): 한(1), 두(2), 세(3), 네(4), 다섯(5), 여섯(6), 일곱(7), 여덟(8), 아홉(9), 열(10) Note: 하나→한, 둘→두, 셋→세, 넷→네 when placed before a counter. The counter 장 comes right after the number. The noun can come before or after the number+counter, but before is more natural in conversation.

Real Examples

• 종이 다섯 장이 필요해요. (jongi daseot jangi piryohaeyo.) — "I need five sheets of paper." [Thin, flat items] • 사진 한 장 찍어 주세요. (sajin han jang jjikeo juseyo.) — "Please take one photo." [한 장 = one shot]

Common Mistakes

❌ Using Sino-Korean numbers with 장 ✅ Use native Korean numbers: 종이 다섯 장이 필요해요. → 장 always takes native Korean numbers. Mixing number systems is one of the most common counter mistakes. ❌ Saying the number without a counter (e.g., "사과 세") ✅ Always include the counter: 종이 다섯 장이 필요해요. → Dropping the counter sounds incomplete in Korean, like saying "three of" without finishing the phrase in English.

Quick Tip

Start with the 5 most common counters: 개 (things), 명 (people), 마리 (animals), 잔 (cups), 병 (bottles). Once these are automatic, add 장 to your toolkit. Practice counting things you see daily: "커피 두 잔", "사람 세 명". The more you use counters in real situations, the faster they become natural.
