张 (zhāng) is one of the first specific measure words worth mastering, because it covers so many everyday objects. Its core image is a flat surface — something with a broad, thin, spreadable face. A sheet of paper, a ticket, a map, a photo, a table top, a bed: picture each as a flat plane and you can predict that it takes 张. English has no grammatical equivalent — the closest is the counter phrase "a sheet of paper," "a slice of…" — but where English uses "sheet" for paper alone, Chinese uses 张 as a whole category of flat things. Getting 张 right instead of defaulting to 个 is one of the quickest ways to sound less like a beginner.
The flat-surface image
The unifying idea behind 张 is a surface you could spread out or lay flat. Once you see the image, the membership list stops feeling arbitrary:
| Noun | With 张 | Meaning |
|---|---|---|
| 纸 (zhǐ) | 一张纸 (yì zhāng zhǐ) | a sheet of paper |
| 票 (piào) | 两张票 (liǎng zhāng piào) | two tickets |
| 地图 (dìtú) | 一张地图 (yì zhāng dìtú) | a map |
| 照片 (zhàopiàn) | 一张照片 (yì zhāng zhàopiàn) | a photo |
| 桌子 (zhuōzi) | 一张桌子 (yì zhāng zhuōzi) | a table |
| 床 (chuáng) | 一张床 (yì zhāng chuáng) | a bed |
| 卡 (kǎ) | 一张卡 (yì zhāng kǎ) | a card |
| 画 (huà) | 一张画 (yì zhāng huà) | a painting |
Note the two members that surprise English speakers: 桌子 (table) and 床 (bed). They are solid furniture, not thin at all — but Chinese classifies them by their defining flat top, the surface you use. This is the logic to internalise: 张 tracks the functional flat plane, not the total thickness of the object.
请给我一张纸，好吗？
qǐng gěi wǒ yì zhāng zhǐ, hǎo ma?
Could you give me a sheet of paper? (polite) — the prototypical 张 noun.
我买了两张电影票。
wǒ mǎi le liǎng zhāng diànyǐngpiào
I bought two movie tickets. (informal) — tickets are flat, so 张.
墙上挂着一张世界地图。
qiáng shang guà zhe yì zhāng shìjiè dìtú
There's a world map hanging on the wall. (neutral) — maps spread flat: 张.
Beds, tables, and other "flat-top" objects
The furniture cases deserve their own note because they trip people up. A table is classified by its top; a bed by its sleeping surface. This extends to a few other broad-surfaced items:
这张桌子太大了，搬不进去。
zhè zhāng zhuōzi tài dà le, bān bú jìnqù
This table is too big — it won't fit through. (informal) — 桌子 takes 张 for its flat top.
宿舍里有四张床。
sùshè li yǒu sì zhāng chuáng
There are four beds in the dorm. (neutral) — beds are counted with 张.
他递给我一张名片。
tā dì gěi wǒ yì zhāng míngpiàn
He handed me a business card. (neutral) — cards, like paper, are 张.
Modern life keeps feeding new members into 张 by analogy: a bank card (一张银行卡, yì zhāng yínhángkǎ), a SIM card, a subway pass, a boarding pass — all flat rectangles, all 张. A sofa is often 一张沙发 (yì zhāng shāfā) by the flat-seat image, though 个 is also heard.
The "flat expanse" extension: mouths and faces
By a natural stretch of the same image, 张 also counts a mouth and a face — the broad, openable expanse of the front of the head. This feels poetic to English speakers, but it's completely ordinary Chinese:
她有一张很甜的笑脸。
tā yǒu yì zhāng hěn tián de xiàoliǎn
She has a very sweet smiling face. (neutral, slightly literary) — 脸 (face) as a flat expanse takes 张.
这孩子一张嘴就把大家逗笑了。
zhè háizi yì zhāng zuǐ jiù bǎ dàjiā dòuxiào le
The moment this kid opens his mouth he has everyone laughing. (informal) — 一张嘴 here doubles as 'open the mouth', built on the 张 = mouth image.
The verb 张 (zhāng, "to open wide," as in 张嘴 "open the mouth," 张开 "spread open") is the same character and the historical source of the classifier — 张 originally meant "to stretch a bow / spread flat." Knowing that root makes the whole category feel motivated rather than memorised.
Contrast with 个
The single most common mistake is using the all-purpose 个 (ge) for these flat items. 个 will be understood — it's the general default — but it flattens the vividness that native speakers hear, and in some cases it sounds clearly off. The contrast to keep sharp is 张 vs the neighbouring classifiers for thick bound things and long thin things:
| Object | Right classifier | Why |
|---|---|---|
| 一张纸 (a sheet of paper) | 张 | flat, thin surface |
| 一本书 (a book) | 本 (not 张) | thick, bound — see 本 |
| 一条路 (a road) | 条 (not 张) | long and narrow, not a broad plane |
| 一个盒子 (a box) | 个 | a 3-D lump, no defining flat face |
The cleanest test case is paper versus book: a single loose page is 一张纸, but the moment those pages are bound into a volume it becomes 一本 (see 本 for bound volumes). The physical form changed, so the classifier changed.
桌子上有一张纸和一本书。
zhuōzi shang yǒu yì zhāng zhǐ hé yì běn shū
There's a sheet of paper and a book on the table. (neutral) — 张 for the loose sheet, 本 for the bound book, side by side.
Common Mistakes
1. Defaulting to 个 for flat things. 个 is understood but sounds unpolished for prototypical 张 nouns like paper, tickets and photos.
❌ 我买了两个票。
Marginal — 票 is flat; native speakers say 两张票.
✅ 我买了两张票。
wǒ mǎi le liǎng zhāng piào
I bought two tickets. — 张 is the natural classifier for tickets.
2. Using 张 for a book. A book is bound and thick; it takes 本, not 张. Only a single loose page is 张.
❌ 我在看一张书。
Incorrect — a book is bound, so it takes 本, not 张.
✅ 我在看一本书。
wǒ zài kàn yì běn shū
I'm reading a book. — 本 for the bound volume.
3. Forgetting that furniture like tables and beds take 张. Learners assume solid furniture must be 个, but Chinese classifies these by their flat top.
❌ 房间里有一个床。
Marginal — a bed is counted by its flat surface: 一张床.
✅ 房间里有一张床。
fángjiān li yǒu yì zhāng chuáng
There's a bed in the room. — 张 for the bed's flat sleeping surface.
4. Using 二 instead of 两 before 张. For "two" in front of a measure word, it's 两, never 二.
❌ 二张地图
Incorrect — before a measure word 'two' is 两, not 二.
✅ 两张地图
liǎng zhāng dìtú
two maps — 两张, not 二张.
Key Takeaways
- 张 (zhāng) classifies things with a flat surface: 纸 (paper), 票 (tickets), 地图 (maps), 照片 (photos), 卡 (cards), 画 (pictures).
- It also covers flat-topped furniture — 桌子 (tables) and 床 (beds) — classified by their defining surface, not their thickness.
- By extension it counts a mouth and a face (一张嘴, 一张脸), from the root sense "spread flat / stretch open."
- The sharpest contrast: a loose page is 一张纸, but bound pages become 一本 (book); don't let 个 blur these.
- Use 两, not 二, for "two": 两张票.

- 条 (Long & Thin)HSK 1 — 条 (tiáo) is the measure word for long, thin, flexible or winding things — fish, roads, rivers, trousers, scarves, snakes, dogs and even a piece of news: 一条鱼, 一条路, 一条裤子.
- Choosing the Right ClassifierHSK 2 — A decision procedure for picking the right Chinese measure word: default to 个 when stuck, otherwise match the noun by shape, category, or the respect it deserves — plus a reference table of the ~15 classifiers that cover most everyday nouns.
- The Default 个HSK 1 — 个 (gè, usually neutral-toned ge) is the general-purpose measure word — the safe fallback when you don't know the specific classifier — and it correctly covers people, many everyday objects, and abstract nouns; the goal is to graduate to specific classifiers while keeping 个 for the nouns that genuinely take it.
