Iron Distance Calculator — Head Speed, Spin Rate, and Club-by-Club Estimates
Estimated Carry Distance by Club
Below are estimated iron distances by head speed. Smash factor is assumed at a standard value for each club, with spin rate at an ideal value.
| Club | HS 33 m/s | HS 36 m/s | HS 40 m/s | HS 43 m/s |
|---|---|---|---|---|
| 5I | approx. 125 yd | approx. 140 yd | approx. 160 yd | approx. 175 yd |
| 6I | approx. 115 yd | approx. 132 yd | approx. 150 yd | approx. 165 yd |
| 7I | approx. 108 yd | approx. 124 yd | approx. 140 yd | approx. 155 yd |
| 8I | approx. 100 yd | approx. 114 yd | approx. 130 yd | approx. 143 yd |
| 9I | approx. 90 yd | approx. 105 yd | approx. 120 yd | approx. 132 yd |
| PW | approx. 80 yd | approx. 95 yd | approx. 110 yd | approx. 120 yd |

The Relationship Between Spin Rate and Distance
Unlike with a driver, a moderate amount of backspin is essential for irons to stop the ball on the green. However, excessive spin causes significant carry loss and makes the shot more vulnerable to wind due to what's known as "ballooning."
Adjust the spin rate slider (3,000–10,000 rpm) in this tool to see the effect on trajectory height and carry distance in real time. If you know your actual spin rate from a TrackMan or GC Quad, enter that value and compare it against your real-world carry distance.
