By increasing the diameter of the grommet holes, this technology achieves 26 degrees of string movement, for a bigger sweet spot. Since the string bed is allowed to flex more when impacted by the ball, the result is a smoother feel and added power.

Junior rackets typically come in smaller sizes than adult racquets. The average head sizes for junior racquets are: [19"—82 sq. in.], [21"—90 sq. in.], [23"—98 sq. in.], [25", 26"—100 sq. in.]. Sizes smaller or larger than average can be selected using the browse option.
Weight is related to resistance to movement in a straight line. For example, the racquet resists your lifting efforts until you apply a force equal to its weight; only then can you lift it. You can feel the racquet’s weight by picking it up by the tip or handle, allowing the other end to hang down, or by picking it up at its balance point. Weight influences balance and swingweight, but it is rarely what the player experiences directly when interacting with the racquet.
An alternate way of measuring balance. A 27 inch racquet is evenly balanced at 13.5 inches. If the balance point were at 12.5 inches, the racquet would be 1 inch, or 8 points, head-light; a 28 inch racquet with a balance point of 15 inches is 1 inch (or 8 points) head-heavy. Static balance ultimately affects swingweight (q.v.)—a dynamic measure of racquet maneuverability.
The number of mains—strings running from handle to head—and crosses—strings running from left to right—in the string bed. A denser string pattern puts more strings in contact with the ball. If you want more control over your shots and are less concerned with power, you want a dense string pattern, such as 18 mains × 20 crosses. An open string pattern, like 14 mains × 18 crosses, gives more power but less control.
