Roger Federer uses a 4 3/8-inch grip size. This may seem small. However, the smaller grip size gives Federer the ability to get more wrist snap on his serves. Many other top players also like to downsize on the grip including Nadal who uses a 4 ¼ grip.

There have been many conversations in recent years regarding Rafael Nadal’s and Roger Federer’s grip sizes. Nadal uses a 4 ¼ inch grip, while Federer uses a 4 3/8 inch grip. Both professional players use overgrip, which does increase the grip size by about a 1/16 inch, but by the end of a match, this width has gone back down due to wear.
