How to use it
Estimating quantity or time, or stating a degree (including a low degree, "that's the least ~").
- Use 1 — ESTIMATION: 「三十分ぐらいかかります」(it takes about 30 minutes). This is the most common way of giving an approximate quantity in conversation.
- Use 2 — STATING A LOW DEGREE, implying "that's the least you could do": 「自分の部屋ぐらい掃除してください」(at least clean your own room). ほど does NOT carry this nuance — this is the second important distinguishing point after negative comparison.
- A quick comparison with ほど: (a) negative comparison "not as ~ as" → only ほど; (b) belittling, "that's the least ~" → only くらい; (c) everyday quantity estimation → くらい sounds more natural, ほど more formal; (d) stating a strong degree (painful to the point of ~) → both work.
- くらい and ぐらい are identical in meaning. In practice, Japanese speakers say ぐらい more often after a counted number (三つぐらい), while くらい is more common after この/その/あの (このくらい).
Examples
駅まで歩いて十分ぐらいかかります。
It takes about ten minutes to walk to the station.
自分の部屋ぐらい掃除してください。
At the very least, please clean your own room.
毎日どのくらい日本語を勉強しますか。
About how long do you study Japanese every day?
Keep in mind
- Don't confuse this with ころ/ごろ: ごろ is used for a POINT IN TIME (三時ごろ — around 3 o'clock), くらい is used for an AMOUNT of time (三時間くらい — about 3 hours).
- どのくらい = "about how much/how long" — a very commonly used question.
Common mistakes
-
Wrong正確に三時くらいに会いましょう。
Let's meet at exactly 3 o'clock.
Correct三時ごろに会いましょう。
正確に (precisely) contradicts くらい (approximately, not exact) within the same sentence — if you want an exact time, drop くらい; if you want an approximate time, drop 正確に and use ごろ.
-
Wrong弟は兄くらい背が高くないです。
My younger brother isn't as tall as my older brother.
Correct弟は兄ほど背が高くないです。
The negative comparison "not as ~ as" only uses ほど, not くらい.
Exam tips
- Classic trap: 三時ごろ (around 3 o'clock) ↔ 三時間くらい (about 3 hours) — check whether 間 is present or not.
