The truth is, there is not a single answer to how many dimples are on a golf ball. That’s because the number of dimples varies depending on the model and manufacturer. Most often, the number of dimples per golf ball falls between 300 and 500.
Golf manufacturers don’t put dimples on golf balls because it looks good. There is real science behind their use. A flat or irregular object moves through the air in an inconsistent, fluctuating manner because of how air flows over it. So golf balls without dimples would travel unpredictably through the air. Essentially, golfers would have little hope controlling a smooth golf ball.
When dimples are added to a golf ball, it creates a tiny layer of air around the golf ball that significantly cuts down drag. This forces the air to flow over a larger portion of the ball, which results in a much smoother ball flight. (Note: Dimple science doesn’t just work for golf balls, apparently it works for cars, too.)
Finally, golf balls have dimples for the purpose of lift. As much as half of the lift a golf ball receives is caused by a backwards spinning motion. When a ball spins backwards, the air pressure underneath it is greater than above it, so the ball rises in the air. Dimples magnify this effect, contributing as much as 50% to the total lift.
