Piano is easier to make a correct sound on and teaches reading in both hands; guitar is easier to carry and more immediately social. Fit matters more than either — a guitar too large to hold gets abandoned quickly.
What piano gives a young learner
Both hands reading at once, visible logic in the layout, and no discomfort in the fingertips.
What guitar gives
Portability, a repertoire of songs within a few chords, and the social side that keeps teenagers playing.
The deciding factor
Whether the instrument fits and whether it can be played where the child actually lives. Both come before the choice of instrument.
The questions players ask
What size guitar for a child?
Match the body and scale to the player rather than the age, and pay attention to body depth — a child can often reach the frets of an instrument they cannot comfortably hold.
Does a keyboard need to be full size?
Full-size keys, yes, so the hand learns the right distances. Sixty-one of them is plenty to begin with.
