Golf Club Distance Calculator: Full Bag Mapping

From a published TrackMan swing-speed chart: each club has a typical carry factor per 1 mph of driver clubhead speed — driver 2.40, 3-wood 2.17, 5-wood 2.05, hybrid 2.01, 4-iron 1.81, 5-iron 1.73, 6-iron 1.63, 7-iron 1.54, 8-iron 1.43, 9-iron 1.32, pitching wedge 1.21. Multiply by your driver swing speed: at 95 mph, a driver carries 2.40 × 95 = 228 yards and a 7-iron carries 1.54 × 95 = 146.3 yards. Gap, sand, and lob wedge factors (1.10, 0.99, 0.88) are extrapolated from standard 10–12 yard wedge gapping and are editable, as is every baseline number on the page.

Smash factor is ball speed divided by clubhead speed — a measure of strike quality. TrackMan PGA Tour averages give typical values: driver 1.48 (167/113), 3-wood 1.48, 5-wood 1.47, hybrid 1.46, 4-iron 1.43, 5-iron 1.41, 6-iron 1.38, 7-iron 1.33 (120/90), 8-iron 1.32, 9-iron 1.28 (109/85), pitching wedge 1.24. This calculator pre-fills those defaults and scales carry when you edit them: at 100 mph driver speed with smash 1.48, ball speed is 100 × 1.48 = 148 mph and baseline carry is 2.40 × 100 = 240 yards.

Carry is how far the ball flies through the air before first touching the ground; total adds the roll after landing. This calculator shows both: total = carry × (1 + roll%), with typical default roll of 12% for the driver, 7% for the hybrid, 3.5% for a 7-iron, and 0.5% for a lob wedge — all editable for firm or soft conditions. Example: a 228-yard driver carry with 12% roll gives 228 × 1.12 = 255.4 yards total.

Three published rules of thumb, each editable in the advanced settings. Elevation: about 1.5% more carry per 1,000 ft (published range 1–2%), so a 228-yard carry at 5,000 ft becomes 228 × 1.075 = 245.1 yards. Wind is asymmetric: a 10 mph headwind costs about 5.2% (228 × 0.948 = 216.1 yards) while a 10 mph tailwind adds about 3.6% (228 × 1.036 = 236.2 yards), matching Frank Thomas's measured 13/9-yard figures on a 250-yard drive. Temperature: about 0.9% per 10°F above 70°F (≈2.25 yards on a driver), so that 228-yard carry at 90°F becomes 228 × 1.018 = 232.1 yards.

A common fitting rule: 10–15 yards between irons and wedges, 20–25 yards at the top of the bag. This calculator flags any gap under 10 yards (clubs bunch up — consider dropping one) or over 20 yards (a scoring hole — consider a hybrid or utility). Example at 95 mph driver speed: the 7-iron carries 146.3 yards and the 8-iron 135.85 yards, a 10.5-yard gap — right in the healthy window.

Enter the distance you need and it finds the club whose adjusted carry is nearest, then suggests a swing percentage: swing% = target ÷ carry × 100. Example: needing 150 yards with a 95 mph driver swing, the 7-iron (146.3-yard carry) is nearest at 150 ÷ 146.3 × 100 = 102.5% swing. Anything outside 80–105% gets flagged — take more or less club instead of forcing an awkward swing.
