4 iron distance

At tour speed

The anchor row for the 4 iron is the published tour average: 96 mph of club head speed, 137 mph of ball speed, a smash factor of 1.43 and 203 yards of carry, which rolls to about 211 yards on a fairway landing. Carry is ball speed multiplied by 1.48 yards per mile per hour, the club’s own ratio from that row, and ball speed is club head speed multiplied by smash factor.

By swing speed

Slower swings strike the ball a little less cleanly, so the model eases smash factor by 0.01 for every 5 mph below the tour speed, floored at 90 percent of the tour value. The table runs the 4 iron from 55 mph to 100 mph; each row has its own page with the rest of the bag at the same speed.

4 iron carry by club head speed

By handicap

The handicap model ties driver speed to handicap (106 mph for scratch, less 0.95 mph per stroke) and swings every club at the same fraction of its tour speed. The last column prices the yards behind scratch on the published fairway table: every approach played from that much further back than a 150 yard reference.

4 iron carry by handicap

By age

The age model peaks club head speed in the twenties and eases it by decade, anchored to a 15 handicap at 30. A 4 iron at 20 carries 158 yards on the model; at 60 it carries 140 yards, 17 yards shorter.

4 iron carry by age

The clubs either side

For a 15 handicap the 3 iron carries 168 yards and the 5 iron 154 yards, so the 4 iron owns the band from about 157 yards to 164 yards: a gap of 7 yards above it and 7 yards below. Gaps near ten yards are what a well built bag looks like; a gap over 20 is the one to fix.

From 161 yards in the fairway the tour average needs 2.98 strokes to hole out and 3.23 from the rough, so a 4 iron approach that finishes 25 feet from the hole is worth +0.05 against the tour average for a 15 handicap, and one that finishes 40 feet away -0.07.

In PinFlag

Import a launch monitor session and PinFlag turns your 4 iron into a pattern of your own carries, labeled Measured, that stands behind every target you price on the course. Shot Cloud draws the real shots around the spot you are considering, on the hole in front of you, so a tucked pin is compared with the middle of the green on your real spread, not a single yardage.

Every shot you log with the 4 iron on the course records the target and the result, so the pattern keeps growing from real rounds, and Insights shows the club’s proximity, the shots it cost and the shots it won across a season.

Every figure on this page is computed from the published baselines, the same ones PinFlag prices your shots with.
