What is My Grip Size? The popular method for finding your tennis racquet grip size is to follow these simple instruction. On your playing hand, your palm has three main creases. Hold your hand flat, with the fingers alongside one another. Measure from the middle crease of your palm, up the line between your middle and ring fingers, to a point equal to the height of the tip of your ring finger. Typically women will measure between 4 1/8 and 4 3/8, men between 4 3/8 and 4 1/2.
