Golf Grip Sizes: What's the Difference?

Golf grips are commonly available in Undersize, Standard, Midsize, and Jumbo/Oversize. In general, the installed grip diameter increases from Undersize → Standard → Midsize → Jumbo/Oversize. However, these names represent general size categories rather than exact, universal size standards across all grip brands and models.

The Same Size Label Can Have Different Actual Dimensions

Two grips labeled Midsize may not have exactly the same installed diameter if they are made by different brands or have different designs. When comparing grips from different brands or models, check the manufacturer’s stated grip size and specifications rather than assuming the same size label will produce exactly the same installed diameter.

What Affects the Final Installed Grip Size?

The final installed grip diameter is not determined by the size label alone. It can also be affected by grip design and core size, shaft butt diameter, and tape build-up. For example, adding build-up tape under the same grip increases its installed diameter, while a difference in shaft butt diameter can also affect the final installed size.

Bottom Line

Undersize, Standard, Midsize, and Jumbo/Oversize are general grip size categories, with installed diameter typically increasing in that order. The final installed size can vary depending on the specific grip, shaft butt diameter, and tape build-up. If actual dimensions matter, check the manufacturer’s specifications rather than relying on the size label alone.
