The junior rackets are for little kids, around 10 years and younger. It's so that the kids don't hurt themselves handling heavy rackets. If a racket is too heavy for its user, it can also mess up or bring hitches into the player's strokes. Also, using those little rackets and cheap strings allow the kids to focus on getting the sweet spot every time. so when they go to the adult rackets, their ball will be penetrating and good.
Adult racquets are usually longer and heavier than junior racquets
The age range for junior tennis racquets depends on the size of the racquet. A 17-19 inch racquet is for children from the ages of three to five. A 21-23 inch racquet is for children from six to eight years of age. A 25 inch racquet is for kids from eight to ten years of age. A 26-27 inch racquet is for children who are eleven and up.
