Golf Club Distance Estimator

The Physics of the Swing

The most common question amateur golfers ask is, "Which club should I hit from here?" To navigate a golf course effectively, you must know your "carry distances" — exactly how far the ball flies in the air before hitting the ground.

While professional golfers use $20,000 Trackman radar systems to map their bags to the exact yard, you can estimate your entire bag with a high degree of accuracy if you know just one metric: the absolute swing speed of your driver.

The Smash Factor and Trajectory

A golf ball flies based on clubhead speed, the loft angle of the clubface, and how efficiently the club transfers energy to the ball (known in physics as the 'Smash Factor').

Because a pitching wedge has a massive loft angle (roughly 45 degrees), most of the clubhead speed is converted into height and backspin, resulting in a short distance. A driver has very little loft (9 to 11 degrees), converting nearly all of the speed into pure forward distance.

The Estimation Formula

Through thousands of radar data points, the industry has established standard multiplier ratios based on driver swing speed.

General Baselines

For an amateur with a perfectly average 90 mph swing speed:

• Driver: ~216 yards (90 * 2.4)
• 5 Iron: ~146 yards (Driver distance * 0.68)
• Pitching Wedge: ~97 yards (Driver distance * 0.45)
