Junior tennis racquets are recommended for beginners from 4 up to 15 years old.
21 inch racquets are for the smallest group of kids 4-6 Years old.
23 Inch long racquets are for 5-7 Years old beginners.
25 Inch long racquets are for 8-10 years old beginners or for smaller kids who can already play a little.
26 inch long racquets are for advanced smaller kids or for junior players up to 15 Years old who can not handle the adult racquet yet. From our experience some smaller ladies are using better 26 inch junior racquets too.
Most of the tournament level kids who started early beginning at 7-8 years old are using light adult racquets .
