ちょうどいい

ちょうどいい
adjective
just right; perfect (amount/size/timing)
1. just right; exactly right; perfect
Describes something that is exactly the right amount, size, timing, or degree — neither too much nor too little.
このサイズはちょうどいい。
This size is just right.
ちょうどいいタイミングで電話(でんわ)()た。
A phone call came at just the right time.
(あじ)つけがちょうどいいので、(なに)()さなくていい。
The seasoning is just right, so you don't need to add anything.

A very common colloquial expression combining ちょうど (exactly) with いい (good). Used constantly in everyday conversation to describe things that fit perfectly — temperature, timing, amount, size, distance, etc.

COMMON COLLOCATIONS:

  • ちょうどいい(おお)きさ: just the right size
  • ちょうどいい(りょう): just the right amount
  • ちょうどいいタイミング: perfect timing
  • ちょうどいい距離(きょり): just the right distance
  • ちょうどいい温度(おんど): just the right temperature

USAGE:
Can be used as a predicate (ちょうどいい) or as a modifier before nouns (ちょうどいい + noun). Unlike many い-adjectives, this is a fixed phrase and does not conjugate as a single unit — the いい part conjugates normally: ちょうどよかった (was just right), ちょうどよくない (not quite right).

SIMILAR WORDS:

  • ぴったり: fits perfectly (emphasizes exact fit, often physical)
  • 適切(てきせつ): appropriate (more formal, used in writing)
