it's just right
🎯 恰 exactly + 到 reach + 好 good + 处 spot = hitting exactly the right spot
恰到好处 stacks 恰 (precisely) and 到 (arrive at) onto 好处 (a good point or benefit), so the whole means landing precisely at the good point: not too much, not too little, just right.
到 — 刂 knife + 至 (phonetic, 'arrive')
到 is a semantic-phonetic compound. 至 ('to arrive') gives both meaning and sound, while 刂 (knife) was added later, likely as a phonetic reinforcer or to distinguish the written form. The core sense 'to arrive, reach' comes directly from 至, and 到 has carried that meaning since early script forms.
好 — woman 女 + child 子
好 is an associative compound showing a woman 女 beside a child 子, depicting a mother with her baby. From this image of maternal affection it came to mean 'good, fine, pleasing.' The reading hǎo means 'good'; read hào it means 'to like.'
处 — 夂 (foot) + 几 (low table/stool)
Originally depicted a person stopping (夂, an inverted foot) beside a stool (几), suggesting someone settling down in a place. From 'to dwell/stay' the meaning broadened to 'place, location' (chù) and 'to handle, deal with' (chǔ). The simplified form drops the older 虍 top found in 處.
