Estimate golf club carry distance from swing speed and club loft. Map driver through wedge distances for bag gapping and on-course club selection.
Calculate USGA/WHS golf handicap index from score differentials. Enter recent round scores, course rating, and slope to estimate your official handicap.
Calculate golf round statistics including gross score, net score, stableford points, and fairways hit. Track scoring averages and handicap posting.
Smash factor peaks around 1.50 for optimized drivers and 1.30–1.38 for irons. Center-face contact with proper loft maximizes energy transfer.
Ball speed = Club speed × Smash factorSimplified correlation for average launch (12–14°) and spin (2400–2800 rpm). Optimal launch monitor fitting improves accuracy over this estimate.
Carry (yd) ≈ Ball speed × 2.5 − 25 (flat, sea level)Compare your driver speed to benchmarks: PGA Tour average ~113 mph, LPGA ~94 mph, male amateur average ~93 mph, female amateur ~78 mph.
Percentile vs PGA avg (113 mph driver)Updated: July 2026
Speed training increases driver club speed from 90 to 95 mph — expect ball speed gain of 7–8 mph and carry increase of roughly 12–15 yards with maintained smash factor.
A 14-year-old at 85 mph driver speed with 1.43 smash produces ~121 mph ball speed and ~275 yard carry potential as strength and technique develop.
Consistent 100+ mph driver speed suggests stiff or extra-stiff shaft flex. Enter iron speeds separately since iron shaft flex may differ from driver recommendation.
Club head speed is the primary driver of distance, but ball speed and launch conditions determine actual carry. Enter measured or estimated club head speed with club type to calculate expected ball speed, smash factor, and carry distance for driver and irons.
