The quickest and easiest way to determine the grip size is to use your height. This type isn’t as accurate as those that need hand measurements and printouts, but for the most part, it’s easy and clear to use: A 4″ grip is needed if you are under 5’2″. Use a 4 14″ handle if you’re 5’3″ to 5’8″. Use a 4 12″ handle whether you’re 5′ 9″ or taller.
