You probably don’t hit your 7-iron as far as you think

Do amateur golfers really overestimate how far they hit the ball? Eight years after Claude Harmon III made a rather provocative claim about golfers’ distances, millions of shots recorded by Arccos and Shot Scope allow us to answer the question far more accurately. And the numbers can be brutal: depending on handicap, golfers may miss a green short ten to fifteen times more often than they miss it long. Yet this is not simply about ego. It is about how we measure distance, remember our best shots and, above all, make decisions on the golf course.

Back in 2018, Claude Harmon III asked a remarkably simple question: “When was the last time you hit it over the back of a par 3?”

The coach, who has worked with some of the best players in the world, argued that most golfers “vastly over-estimate how far they hit the golf ball”. His advice was almost deliberately simplistic: if you think it is a 6-iron, hit a 5-iron; if you think it is an 8-iron, hit a 7-iron.

Behind the provocative wording was an observation already emerging from the first generation of shot-tracking data: recreational golfers were finishing short far more often than they were finishing long.

At the time, Harmon’s statement could still be interpreted as the empirical observation of an experienced coach. In 2026, we have enough data to go considerably further. Shot-tracking systems have now recorded hundreds of millions — in some cases more than a billion — golf shots. They allow us to compare what golfers think they do with what they actually do.

And that comparison is not always comfortable.

The number that should make golfers think: 69% versus 4%

Shot Scope data published in 2025 provides a fascinating picture of approach-shot misses from more than 50 yards. As handicap increases, the imbalance between short and long misses becomes increasingly dramatic.

A 15-handicap golfer therefore finishes short roughly eleven times more often than long. At a 20 handicap, the ratio approaches fifteen to one. At 25, it exceeds seventeen to one.

Even scratch golfers miss short more than four times as often as they miss long.

The trend becomes even more striking as the shot gets longer. Beyond 150 yards, Shot Scope recorded 50% of approaches short for 20-handicap golfers compared with only 4% long. For 25-handicap golfers, the figures were 63% and 4%.

Beyond 200 yards, the numbers reached 78% short versus 1% long for a 20 handicap, and 95% versus 1% for a 25 handicap.

There is, however, an important caveat. These figures do not mean that every short miss is caused by choosing the wrong club. A ball can finish short because it was hit fat, struck off-centre or played into the wind. A golfer might deliberately favour the front of a green because trouble lies behind it. And from 200 yards, many recreational golfers simply do not possess a club they can reliably hit far enough to reach the green.

But an imbalance of this magnitude still tells us something important:

our management of distance is anything but neutral.

The 20-handicap golfer’s 5-iron: 187 yards in theory, 152 yards in reality

An Arccos study based on more than six million shots produced one of the clearest examples of the problem.

For a scratch golfer using a 5-iron, the average starting distance was 194 yards. Yet the median distance actually travelled by shots recorded with that club was 176 yards.

That is already an 18-yard difference for a scratch player.

For a 20-handicap golfer, the gap became much larger. The 5-iron was selected from an average starting distance of 187 yards, while the median distance actually achieved with it was only 152 yards.

That is a 35-yard gap.

Across all the approach shots studied by Arccos, 40% finished short of the green while just 5% finished beyond it — an eight-to-one ratio.

Arccos co-founder Sal Syed identified one of the reasons: golfers tend to make decisions based on their best shots.

And that may be the real issue.

Your 7-iron doesn’t have one distance

Ask ten golfers how far they hit their 7-iron and most will give you a number.

140 yards. 150. 160. Perhaps 170.

But the question itself is flawed.

A 7-iron does not have a distance.

It has a distribution of distances.

Imagine a golfer who says he hits his 7-iron 160 yards. He may be absolutely right. He might have hit numerous shots that distance. He may even have produced a perfect strike that travelled 165 or 170 yards.

That does not mean 160 yards should be the number around which every decision is built.

A slightly off-centre strike might carry 145 yards. A decent strike could travel 151. A very good one might reach 158. The exceptional shot could fly 165.

The exact numbers will obviously vary enormously between golfers. The point is not the numbers themselves.

It is the dispersion.

Modern tracking systems have gradually changed the way they present this information for precisely this reason. Arccos, for example, uses both Smart Distance and Smart Range. Rather than simply presenting the longest shot a golfer has hit, the system attempts to estimate typical performance while filtering abnormal shots and recovery situations. The range then provides an indication of the distances over which properly struck shots tend to finish.

That distinction matters.

“How far have I hit my 7-iron?” and “What distance can I reasonably expect from my 7-iron?” are two completely different questions.

The first may flatter the golfer.

The second may save shots.

We remember the 165-yard 7-iron

There is also a very human element to the problem.

Imagine hitting ten 7-irons. Two are poor. Five are ordinary. Two are very good. The final shot comes straight out of the middle of the clubface, produces that unmistakable sensation of perfect contact and flies ten yards farther than normal.

Which shot are you going to tell your friends about in the clubhouse?

Probably the last one.

And which shot is in danger of becoming your mental reference for that club?

Again, probably the last one.

This is reinforced by the language golfers traditionally use when discussing distance. Saying “I hit my 7-iron 160 yards” rarely means that the golfer has calculated a statistically robust average from dozens of shots.

More often, it describes a distance the golfer knows he is capable of reaching.

But maximum capability and probable outcome are not the same thing.

On-course tracking removes some of this selective memory because it records the ordinary shots as well as the spectacular ones. Those are the shots nobody talks about at the bar.

A golfer does not necessarily discover that he is shorter than he thought.

He discovers something more useful:

his best shot is not his normal shot.

Carry and total distance are not the same thing

There is another common source of confusion: carry distance versus total distance.

A shot might carry 150 yards and roll to 160. On a dry fairway, those additional ten yards are real.

But if your next shot needs to clear a bunker whose front edge is 155 yards away, your club no longer “goes 160”.

For the decision you are facing, it goes 150.

The distinction sounds obvious. On the golf course, it is surprisingly easy to forget.

Distance is also affected by wind, temperature, elevation, lie, slope and quality of contact. Modern systems increasingly attempt to account for these variables when calculating adjusted distances.

This leads to a broader point.

Knowing your distances does not mean owning a piece of paper containing 14 numbers for the 14 clubs in your bag.

You need to understand your carries, your dispersion and how those numbers change with conditions.

Tiger Woods did almost exactly what amateurs don’t

Tiger Woods provides an illuminating comparison.

In an analysis published by GOLF.com using a model developed with statistician Lou Stagner, Woods’ fairway approaches from 150 to 200 yards were examined according to how far they finished relative to the hole.

The result was remarkable:

49.9% finished beyond the hole.

Which, of course, means that almost exactly half finished short.

His distance dispersion was effectively centred on pin-high.

PGA Tour players are extraordinarily precise compared with recreational golfers, yet the Tour average in the same analysis still finished almost two yards shorter than Woods.

The lesson is not that Tiger Woods deliberately tried to hit the ball beyond every flag.

It is far more interesting than that.

His margin of error was distributed around the correct distance.

Compare that almost symmetrical distribution with the 69% short and 4% long recorded among 25-handicap golfers.

Clearly, we are comparing golfers with completely different levels of ball-striking ability. But the contrast illustrates the difference between building a decision around a probable outcome and hoping your best strike appears at exactly the right moment.

Tiger Woods could not know precisely where every ball would finish.

Nobody can.

What he understood exceptionally well was the area around which his shots were likely to be distributed.

Should you simply take one more club? Not so fast

This is where Claude Harmon III’s original 2018 advice needs some qualification.

“If you think 7-iron, hit 6-iron” can be an excellent experiment for some golfers.

It is not a universal law.

Imagine a 30-yard-deep green. The front is 140 yards away, the flag is at 150 and there is plenty of room beyond the putting surface. A deep bunker protects the front.

Playing for 155 or even 160 yards may be perfectly rational.

Now reverse the situation. There is no serious trouble short, but out of bounds begins just a few yards behind the green.

Suddenly, favouring the short side can be an excellent decision.

General statistics do not know the architecture of the hole, your lie, wind direction, your lateral dispersion or the relative cost of different misses.

More importantly:

taking an extra club does not repair poor contact.

A golfer who repeatedly finishes short because he selects his “160-yard 7-iron” for a 160-yard shot when his normal carry is actually 150 has a decision-making problem.

A golfer who finishes short because he regularly hits the ball fat has primarily a strike problem.

Both balls may finish in exactly the same place.

The diagnosis is completely different.

Beyond 200 yards, the problem changes

The Shot Scope figures from beyond 200 yards deserve a different interpretation.

Among 20-handicap golfers, 78% of these approaches finish short and only 1% long. For 25-handicap golfers, 95% finish short.

Should those players simply take more club?

Not necessarily.

At 200 yards, many recreational golfers simply do not possess a club that can reliably produce the required carry. Pulling a 3-wood does not magically transform a 190-yard shot into a reliable 205-yard shot. It may simply increase dispersion and the potential cost of the miss.

The best decision may therefore be not to attack the green at all.

This is the distinction between required distance and available distance.

When the golf course asks for a shot that a player does not reliably possess, strategy is no longer about finding a club that might theoretically reach the target. It becomes about identifying the position from which the next shot will be easiest.

Knowing your distances is therefore also about knowing when not to go for it.

So how far do your clubs really go?

There is a simple principle: stop looking for records.

Useful gapping should ideally be performed with a launch monitor or another system capable of measuring carry. A handful of shots is not enough. The goal is to build a representative sample over time, identify obvious mishits without conveniently deleting every imperfect strike, and examine the resulting distribution.

What you want to avoid is this:

7-iron: 160 yards.

Something closer to this is far more useful:

7-iron: typical carry on a solid strike, normal distance window, exceptional-strike distance.

Those numbers can then be compared with what actually happens on the golf course.

The course matters because it introduces everything a perfect practice mat removes: uneven lies, rough, slopes, wind, pressure and ordinary contact.

Your real golf game is not made entirely of perfectly struck balls from a perfectly flat lie.

Ask a different question before your next approach

Most golfers still make their decisions something like this:

“I have 155 yards. Which club goes 155 yards?”

That may be too simplistic.

A more rational process starts by establishing the distance that absolutely has to be carried, the distance to the flag, the amount of room behind it and the severity of the hazards short and long.

Only then should those numbers be compared — not with the maximum distance of a club — but with its likely distribution.

A bunker at 150 yards does not require you to know which club can reach 155.

It requires you to know which club carries beyond 150 often enough.

It sounds like a subtle distinction.

It completely changes the decision.

Golf then becomes less about hitting exact numbers and more about managing probabilities.

Claude Harmon was right — but the data now takes us further

When Claude Harmon III argued in 2018 that golfers vastly overestimated how far they hit the ball, the first generation of shot-tracking technology was already giving him evidence for what coaches had observed for years.

Millions of recorded shots since then have reinforced the underlying pattern: recreational golfers finish short far more frequently than they finish long.

But the data now allows us to describe the problem more accurately.

A golfer does not necessarily overestimate the distance of every shot.

When somebody says he hits his 7-iron 160 yards, he may be telling the truth. Some of his shots really do travel 160 yards.

The mistake is turning a possibility into a prediction.

That may be one of the most important distinctions in course management.

Your 7-iron is not the perfect shot you hit last Sunday.

It is not even necessarily an average.

It is a distribution of outcomes, with a central tendency, misses, extremes and different probabilities of reaching different distances.

So the next time your rangefinder reads 155 yards, perhaps the most useful question is no longer:

“Which club goes 155 yards?”

It is:

“Which club gives me the best probability of finishing in the right place?”

That may be less flattering to the ego.

But it is probably much better for the scorecard.
