FORMATION:
(おお)きい (big) → (おお)きさ (size). The ~さ suffix converts い-adjectives into nouns expressing degree or extent: (たか)い → (たか)さ (height), (なが)い → (なが)さ (length), (ひろ)い → (ひろ)さ (width/spaciousness).

COMMON PATTERNS:

  • (おお)きさが(ちが)う (to differ in size)
  • (おお)きさが(おな)じ (to be the same size)
  • (おお)きさを(はか)る (to measure the size)
