Compare L1, L2 and L3 labels, take a starting measurement and check the handle with the overgrip you use on court.
Read the size label
Grip size describes handle circumference, not diameter. Labels may use numbered sizes such as L1, L2 or L3, or a circumference in inches. Check the manufacturer’s chart for the model; the same size number can feel different with a different handle shape.
What do L1, L2 and L3 mean?
These labels describe handle circumference. In Babolat’s size chart, L1 corresponds to 4 1/8 inches, L2 to 4 1/4 and L3 to 4 3/8. One size step is 1/8 inch: about 3.2 mm around the handle.
Measure before trying a racket
Babolat’s starting method measures from the middle palm crease to the tip of the ring finger. Compare that distance with the manufacturer’s hand-size chart. Keep hand length and handle circumference separate when reading the columns.
Account for Grips and Overgrips
The replacement grip is the main wrap on the handle; an overgrip is a thin extra wrap over it. Changing the main grip’s thickness or adding an overgrip changes the finished circumference and feel. Try the racket with the wraps you expect to use.
Try normal grip changes
Move between forehand, backhand and serve grips. The handle should feel secure without needing to squeeze constantly. Handle shape differs between models, so circumference alone is not the whole story.
When You Are Between Sizes
Try both sizes before modifying a frame. Small changes are easier to assess one at a time. If playing causes persistent pain, stop and seek suitable professional advice rather than relying on a grip change as treatment.
