7 iron distance at age 20

A golfer of 20 carries a 7 iron about 134 yards on the age model, at 72 mph of club head speed, and totals 139 yards on a fairway landing. That is the peak of the model; every later decade sits behind it.

The model

The age model puts driver club head speed at 90 mph for a golfer of 20: it peaks in the twenties, eases slowly to 30 and then falls about 0.35 mph a year, anchored to a 15 handicap at 30. Every club swings at the same fraction of its tour speed, which gives the 7 iron 72 mph, a smash factor of 1.30, 93 mph of ball speed and 134 yards of carry on the published tour row.

By decade

The same club across the age bands. Distance ages slowly and then quickly: the last column is how far each decade sits behind the peak.

What the yards cost

At the peak there is nothing to give back. What the later decades show is how much the same golfer loses per approach on the published fairway table as every shot starts further from the hole, and the table below the fold on each later page prices it.

From 134 yards in the fairway the tour average needs 2.89 strokes to hole out and 3.13 from the rough, so a 7 iron approach that finishes 25 feet from the hole is worth -0.04 against the tour average for a golfer of 20, and one that finishes 40 feet away -0.17.

The bag at 20

Every club at the same age, so the 7 iron reads against the rest of the set.

In PinFlag

Import a launch monitor session and PinFlag turns your 7 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 7 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. The scope of the figures: The age model eases a peak club head speed by decade and swings the 7 iron at the same fraction of its tour speed; the carry is the published tour anchor at that speed, and your own launch monitor carries replace it in the app.
