💡 Practical Tips
Measure on a relaxed hand
Keep your fingers loose so the calculator starts from a neutral fit, not a clenched grip.
Use layers for small changes
One overgrip or sleeve step is often enough to fine-tune comfort without overcorrecting.
Use this tennis racket grip size calculator to compare hand measurements, current handle size, and overgrip build-up, then confirm a comfortable starting point before your next session.
The grip size of a tennis racket is the measurement of the circumference of the racket handle. The grip size of a racket will determine in what way that a person hold the racket. If the racket grip size is too small for that individual, it is possible that the racket handle will slip from that players hand, and the hand muscles will cramp if the racket size are too small.
If the racket size is too large for the individual, that persons wrist may become locked when gripping the racket, and that player may have difficulty in controlling the racket with such a large grip size. To determine the correct racket grip size for an individual, you must measure the dimension of that persons hand. The player fingers should be stretched out across a flat surface, as their hand will be relaxed.
How to choose the right tennis racket grip size
The length of the hand can be measured from the wrist to the tip of the longest finger of that player, the width of the palm can be measured across the knuckles, and the span of the fingers can be measured from the base of the middle finger to the crease of the palm. These measurements will help determine the appropriate racket grip size for that individual; those with long and narrow hands tend to have similar grip size than those with short and wide hands. In addition to the dimensions of the players hand, you must consider the current state of the racket handle.
The racket handle may have layers on it that contribute to the thickness of the handle; overgrips are thin layers that can be wrapped around the handle to increase its thickness by approximately one-sixteenth of an inch each. Sleeves are thicker than overgrips and increase the thickness of the racket handle more than overgrips do. Therefore, if a player add many overgrips or many sleeves to a racket handle, the handle will become thicker.
The type of player that an individual is may also impact the grip size of the racket that they use. For instance, an individual that play with a one-handed backhand may have a different grip size preference then an individual that plays with a two-handed backhand. An individual that serves with both hands may prefer a racket grip size with more cushioning than an individual that plays mostly at the net.
Racket handles are not made up of perfect cylinders; they are made up of octagonal shape with eight edges, called bevels. An individuals racket grip size is measured along these bevels. Additionally, if the racket grip size is too small for an individual, it is possible to increase the thickness of the racket handle with overgrips; however, if the size of the racket grip is too large for an individual, it is more difficult to make the racket handle thinner.
There are several factor that may lead to an individual incorrectly selecting the racket grip size that will be best for themselves. For instance, if an individual measures their hand while their hand is tense, the measurements will be incorrect. If an individual does not consider the amount of sweat that may be on their hand when selecting their racket grip size, the racket handle may slip while they are playing tennis.
Finally, if an individual adds too many overgrips or sleeves to their racket handle, the bevels may blur, making it difficult for that individual to control their racket. In order to ensure that an individual has set the racket grip size to the correct thickness, the player should of test the racket while they are on the tennis court. If the individual grips the racket and begins to hit a few forehand shots with the racket, the player can evaluate their grip size.
If the player experiences their fingers splaying when hitting the ball, their racket grip size is too small for that individual; they should add overgrips to increase the thickness of the handle. Additionally, if the player experiences that their hand begins to cramp while playing tennis, their racket grip size is too large; they should decrease the thickness of the racket grip. The addition of only one overgrip is a common adjustment in changing racket grip size for an individual to test the difference.
It is important to recieve the right feel for the handle so you dont struggle during a match. Actually, many people dont realize how much the grip matters. If you want to play more comfortabley, you should check your equipment.
Its easy to overlook this, but the right size can help a lot. Using a moddern racket doesnt help if the grip is wrong.
