Golf ball
A regulation golf ball has a minimum diameter of 1.68 inches (4.27 cm) and a maximum weight of 1.62 ounces (45.93 grams), as specified by the Rules of Golf. This page covers the exact dimensions, weight limits, and how a golf ball compares to other small sports balls.
Dimensions
| Measurement | Inches | Centimeters |
|---|---|---|
| Minimum diameter | 1.68 | 4.27 |
| Circumference | 5.28 | 13.4 |
Unlike many sports balls, golf ball regulations set a minimum diameter rather than a fixed range, and manufacturers generally produce balls very close to this minimum to maximize aerodynamic efficiency and distance.
Weight
A golf ball may not weigh more than 1.62 ounces (45.93 grams). There is no minimum weight specified, but nearly all golf balls sold are manufactured very close to the 1.62 ounce maximum, since a heavier ball generally travels farther when struck.
Dimple count
A typical golf ball has between 300 and 500 dimples on its surface. These dimples reduce air resistance and create lift, allowing a golf ball to travel roughly twice as far as an equivalent smooth ball struck with the same force.
Golf ball vs tennis ball
| Ball | Diameter (in) | Weight (oz) |
|---|---|---|
| Golf ball | 1.68 | 1.62 |
| Tennis ball | 2.57 to 2.70 | 1.98 to 2.10 |
A golf ball is smaller and lighter than a tennis ball. Its compact, dense construction is built for distance off a club face rather than compression against a racket string bed.
Frequently asked questions
What is the diameter of a golf ball?
A minimum of 1.68 inches (4.27 cm), the smallest size permitted under the official Rules of Golf.
How much does a golf ball weigh?
A maximum of 1.62 ounces (45.93 grams). Most golf balls are manufactured close to this limit.
How many dimples does a golf ball have?
Typically between 300 and 500, though the exact number varies by manufacturer and model.
Why do golf balls have dimples?
Dimples reduce air resistance and generate lift, allowing the ball to travel significantly farther than a smooth ball hit with the same force.
Is a golf ball smaller than a tennis ball?
Yes. A golf ball’s 1.68 inch diameter is noticeably smaller than a tennis ball’s 2.57 to 2.70 inch diameter.
