Smash factor is ball speed divided by club speed. Drivers typically achieve 1.48–1.50; irons range 1.25–1.38 depending on loft and strike quality.
Ball speed ≈ Club speed × Smash factorEmpirical correlations from TrackMan data link ball speed and launch conditions to carry. Lower loft clubs with higher ball speed produce longer carry; higher loft trades distance for descent angle.
Carry (yd) ≈ Ball speed (mph) × Loft factor × 2.3Compare calculated carry for each club in your bag. Gaps wider than 15 yards suggest a missing club; gaps under 8 yards indicate redundant clubs.
Ideal gap = 10–15 yd between consecutive clubsUpdated: July 2026
At 95 mph driver speed with 1.45 smash factor, expect ball speed near 138 mph and carry around 230–240 yards depending on launch angle and spin.
Hit 5–10 shots with each iron, enter average ball speeds, and compare calculated carries to find whether your 6-iron to 7-iron gap is too tight or too wide.
Reference your calculated 7-iron carry of 150–160 yards to choose the right club for a pin at 155 with a slight headwind.
Knowing your carry distances for each club eliminates guesswork on the course and reveals gapping problems in your bag. Enter club head or ball speed with club type and loft to estimate carry distance based on launch monitor correlations and typical amateur smash factors.
