Racket Head Size. Whether it be for control, balance, power or stability, the size of the head racket determines what the player is looking for. Most head sizes range from 85 to 135 square inches. Larger racket head appeals more to beginner up to intermediate players who are looking for power and stability.
Currently, 29 inches (73.66 cm) is the maximum length allowed for competitive play under the official rules of tennis. As mentioned earlier, the standard length for a tennis racquet is 27 inches or 68.58 centimeters. As such, you’ll find the vast majority of adult tennis racquets with this length.
In practice, top players tend to prefer rackets with modestly-sized heads. This is due to the fact that they can already generate plenty of power, and what they are looking for is control and maneuverability, which they will get from rackets with smaller heads.
Yes, tennis rackets do make a difference. Most rackets targeted at advanced players have a smaller head size and heavier weight. For a beginner, a size reduction can have a large impact as the sweet spot is reduced.
The smaller the head, the more maneuverable and control-oriented the racquet will be; the bigger the head, the more margin for error and power a racquet will have. Most beginners should use a racquet with a head size between 100 and 115 sq. inches – consider the smaller end of the spectrum if you’re coordinated and/or looking to develop long, fluid swings through practice and lessons.
Racquets that measure between 19 and 23 inches tend to be best for players age 8 and under. Racquets between 23 and 25 inches long are the best for players at the 9 and 10-year-old age level. The 26-inch racquet is best for players adjusting to the 78-foot court.
Many men looking for tennis racquets will find themselves choosing between a size 3 (4 3/8 in) and size 4 (4 1/2 in) grip. If you’re on the fence between the two, I’d encourage you to go with 4 3/8 because it’s much easier to build up a grip than reduce it and the difference between the two is only 1/8 inch or 3.2 mm.
If the racket is of the correct grip size, the distance between your palm and longest finger should approximately be the width of a finger (pictured below). If the gap is too small it means you will need a larger grip size, and if the gap is too big you will need a smaller grip size.
