The grip is the only physical contact the golfer has with the club. Therefore, the club feeling comfortable in the golfer’s hands is essential to consistently strike the ball. Changing your golf grips can improve your game by 3-5 shots per round. The wrong size grips can actually have the opposite effect.

Determining your proper grip size is very easy, and can be done in a short period of time. While using sample grips to determine your proper grip size is the best way, using the guide below can get you to the proper size. If you need to size your grip incorrectly, I suggest you err on the large side, as most players I’ve ever dealt with do better with larger grips.


Hold a club in the playing position.
Raise the club to between waist high and chest high. Remove your right hand from the club (this is for right-handed golfers). If you are left-handed, just reverse the hand described. Maintain your grip on the club with your left hand.


I would recommend that you repeat this step with longer or shorter clubs just to confirm your results.
Turn the club so that you can see your fingertips. Take special care not to move your hand or oversqueeze the club.
Observe the middle, ring and pinkie finger’s relationship with the pad of your palm. Your fingertips should just be lightly brushing your palm pad. If there is a gap, the grip is considered too large. (The only exception would be if you have arthritis, then you would need the larger grips to alleviate pain.) If your fingertips are digging into your palm pad, the grip would be considered too small.
Measure the grip at a point that is 2 inches from the grip cap end with a vernier caliper. This gives you the decimal grip size; then you can use the chart to determine size. If the grip on your club is too big, you’ll need to use your judgment to determine how much too big the grip is. If your grip is too small, continue to step 7.
Use masking tape (or you can use cloth tape) to build up the grip's size. Then repeat steps 1-5 until you create the proper size. When you reach the proper size, repeat step 6.

Finally, here's the chart:

Men’s/Ladies

.869 = -1/32”/under .819 = -1/32”
.885 = -1/64”/.835 = -1/64”
.900 = Standard/.850 = Standard
.915 = +1/64”/over .865 = +1/64”
.931 = + 1/32”/.881 = + 1/32”
