Swing speed to distance chart
Driver carry and 7-iron carry at common driver speeds, from the same model as the calculator. “Average” uses a typical amateur strike; “Tour” uses a centered tour strike. Tap a speed to load an example bag. Distances are in yards.
Distances in yards. Speeds above 115 mph and below 96 mph are extrapolated from the tour data.

Driver loft and shaft flex for 94 mph
Driver loft
9–11°
Slower swings need more loft to get the ball high enough to carry. Most drivers are sold at 9°, 10.5° or 12°, and an adjustable hosel moves that a degree or two.

Shaft flex
Stiff (S)
Typical driver shaft weight for this speed: 60–75 g. Flex labels are not standardized between brands, and a quick transition can call for a stiffer shaft than speed alone suggests. Light flex is often labeled A or Senior.

How the estimate worksTour anchors, contact assumptions and limits+
How the estimate works
Two real bags as anchors. The model uses TrackMan’s 2023 tour averages (published in 2024), with launch data for every club on the PGA Tour (115 mph driver speed) and the LPGA Tour (96 mph driver speed). At those two speeds with tour-level contact, the calculator returns TrackMan’s numbers exactly.
Driver carry from ball speed. Your club speed becomes ball speed through the tour smash factor (about 1.49), reduced for your contact level using TrackMan’s amateur averages. Carry per mph of ball speed rises with speed, from 1.56 yards at 143 mph to 1.65 yards at 171 mph, so the line through those two tour drivers turns ball speed into carry.
Every other club. Each club keeps the share of driver carry that tour players get, blended between the LPGA and PGA bags. Below 96 mph the LPGA proportions apply, and above 115 mph the PGA proportions apply.
What it leaves out. Launch angle, spin, altitude, temperature, wind and ball type. The same speed can produce different carries when strike and launch change. A launch monitor session tells you more than any chart.
Questions
How far should I hit my driver at 90 mph?
About 192 yards of carry with typical amateur contact, and about 205 yards with a centered tour strike. At 100 mph the numbers are about 220 and 235 yards.
How many yards does 1 mph of swing speed add?
About 2.5 yards of driver carry at 70 mph, 2.8 yards at 94 mph and over 3 yards at tour speed. TrackMan puts it at up to 3 yards per mph.
What is a good driver swing speed?
TrackMan’s averages: 94 mph for the average male amateur (14.5 handicap), 110 mph for scratch players, 79 mph for a 15-handicap female amateur, 96 mph on the LPGA Tour and 115 mph on the PGA Tour.
Why do I hit it shorter than this?
Usually contact and launch. Off-center strikes lose ball speed, and a low launch with high spin costs carry. Speed readings also vary between devices, so compare numbers from the same one.
