4 iron distance at 65 mph

A 4 iron swung at 65 mph carries about 131 yards and totals 137 yards on the published tour table, with a smash factor of 1.37 and 89 mph of ball speed. The tour average for the club is 96 mph and 203 yards of carry, so 65 mph sits -31 mph and -72 yards from it.

The number

Ball speed is club head speed multiplied by smash factor: 65 multiplied by 1.37 is 89 mph. Carry is ball speed multiplied by the club’s 1.48 yards per mile per hour from the published tour row: 131 yards. Roll adds 4 percent on a fairway landing, for 137 yards total. The smash factor sits 0.06 below the tour value of 1.43 because the model eases strike quality by 0.01 for every 5 mph below the tour speed.

Speeds either side

The same club 5 and 10 mph either side, which is the range a golfer moves through across a season.

What strike is worth

At 65 mph a strike that moves smash factor by 0.02 moves ball speed by 1 mph and carry by about 2 yards with a 4 iron. Speed is the expensive way to add distance; strike is the cheap one, and a launch monitor session shows which of the two is limiting yours.

The rest of the bag

A golfer who swings a 4 iron at 65 mph swings a driver at about 77 mph on the model, since every club runs at the same fraction of its tour speed. That driver speed maps to about a 31 handicap on the handicap model and about age 74 on the age model. The bag below is every club at that fraction.

In PinFlag

Import a launch monitor session and PinFlag turns your 4 iron into a pattern of your own carries, labeled Measured, that stands behind every target you price on the course. Shot Cloud draws the real shots around the spot you are considering, on the hole in front of you, so a tucked pin is compared with the middle of the green on your real spread, not a single yardage.

Every shot you log with the 4 iron on the course records the target and the result, so the pattern keeps growing from real rounds, and Insights shows the club’s proximity, the shots it cost and the shots it won across a season.
