# Golf at 100 mph swing speed

A driver swung at 100 mph carries about 239 yards and totals 258 yards on the published tour table, with 145 mph of ball speed at a smash factor of 1.45. At the same fraction of tour speed a 7 iron carries 150 yards. The speed maps to about a 6 handicap on the handicap model and above the peak the age model gives a golfer in their twenties; 5 mph more is worth about 14 yards of carry.

## Key figures

- A driver at 100 mph carries about 239 yards and totals 258 yards, with 145 mph of ball speed; a 7 iron at the same fraction carries 150 yards.
- Five mph more, at 105 mph, is worth about 14 yards of carry, or 0.05 of a stroke per approach on the published fairway table.

## Scope

- The carries are the published tour anchors scaled to 100 mph with smash factor easing below the tour speed; the handicap and age mappings are the models stated on the page.
