21 Inch Rackets - 4-6 Years

Kids' tennis rackets in the 21 inch size, which suits most children aged 4 to 6. Junior frames are sized by length rather than age, and length is the number that matters. Too long and they cannot swing it; too short and it is outgrown within a season. Most children move up to a 23 inch frame once they can swing through the ball without the head dropping.

A bigger head is more forgiving on off-centre hits; a heavier frame is more stable against pace but slower to swing. Both figures are on every listing. You might also want junior tennis balls and junior tennis racket bags.
