Greens in Regulation (GIR)
In short
Greens in regulation, or GIR, shows in golf whether you reach the green in the expected number of strokes. That means the ball is on the green after two strokes fewer than par: after the first stroke on a par 3, after the second on a par 4 and after the third on a par 5.
Greens in regulation (GIR): the rule explained
Every hole has a par. Par is the number of strokes a very good player plans for the hole, and it always includes two putts on the green. Take those two putts away and you are left with the number of strokes a player should need to reach the green. That is the regulation, the expected number of strokes.
The calculation is always par minus two. A green is hit in regulation if at least part of the ball touches the putting surface after you have played that number of strokes. If the ball is on the green earlier, it still counts. If it only reaches the green later, it is not a GIR.
On scorecards and in stats apps you tick one box per hole: green hit or green missed. At the end of the round this gives a number between zero and eighteen.
Examples: GIR on par 3, par 4 and par 5 holes
A few examples show how the count works:
- Par 3: the tee shot finishes on the green. One stroke is par minus two, so the green is hit in regulation.
- Par 4: tee shot to the fairway, second shot onto the green. Two strokes are par minus two, so this is a GIR.
- Par 5: tee shot, second shot and third shot onto the green. This is also a GIR. On a par 5 good players have a little more room, because three strokes are available.
A counter-example: on a par 4 your tee shot finds the fairway, your second lands in a greenside bunker and your third, played from the sand, finishes on the green. The green is reached after three strokes, not two. No GIR. A good putt can still save par, and in the statistics the hole then counts as a successful scramble.
The reverse is interesting too: a birdie does not have to come from a GIR. It can come from a holed chip. Most of the time, though, a GIR is behind it.
What counts as the green? Fringe, penalty strokes and overshoots
Three points often confuse beginners.
First, the fringe. This is the short-cut strip around the green. If the ball only lies there and does not touch the putting surface, it does not count as a green hit. If even a small part of the ball touches the putting surface, it counts. Some stats providers also publish a separate figure for greens or fringe in regulation so that you can compare both.
Second, penalty strokes. In the usual statistics they count as strokes. If you hit your tee shot into the water on a par 4, you have already used two strokes after the penalty and the drop, and you play your third. Even a perfect third shot onto the green is then not a GIR.
Third, the ball that runs past the green. It only counts if it stays on the putting surface. A ball that lands on the green and ends up in the rough behind it is not a GIR.
GIR percentage: how many greens do pros and amateurs hit?
The GIR percentage is the share of holes on which you hit the green in regulation. If you hit twelve greens in an 18-hole round, your percentage is about 67 per cent.
For PGA Tour players the tour statistics show a figure of a little over 65 per cent. In 2019 the average was about 66 per cent, which is just under twelve greens per round. Even the best players in the world do not hit every green, and the leaders are at around 70 per cent and slightly above.
Amateurs are well below that. The higher the handicap, the fewer greens are hit in regulation. Beginners often hit only a few greens per round. That is completely normal, because reaching the green takes two accurate shots and both distance and direction have to be right.
One more point for context: the percentage also depends on the course. On a short course with large greens it is higher than on a long course with small, well defended greens.
Why GIR is not enough: putts, scrambling and strokes gained
The percentage says a lot about your approach play, but not everything about your score. Two players can have the same GIR percentage and score very differently. The reason is the length of the first putt. At three metres a birdie is realistic. At twenty metres a par is already a good result.
That is why GIR is usually read together with two other figures:
- Putts per GIR: how many putts do you need once you have hit the green?
- Scrambling: how often do you save par after missing the green? There is more on this under up and down.
Strokes gained is more precise still. It rates every shot by how much it gained compared with an average benchmark. There you can see whether an approach from 150 metres was good even if the ball finished just beside the green. GIR, by contrast, is a simple yes or no figure, which makes it easy to record and easy to understand.
For everyday use, GIR is a good first measurement because you can note it without any technology.
How to improve your GIR percentage
More greens usually come from better distance control, not from more length. Some approaches have proved their worth:
- Know your carry distances. How far does the ball really fly through the air with a 7, 8 and 9 iron? If you only remember the total distance including roll, you often misjudge by a few metres.
- Aim for the middle of the green. Flags are often placed close to bunkers or water. With the middle as your target there is more margin for error.
- Take one more club. Many recreational players finish short because they treat their best strike as the normal one.
- Play the approach from a good position. Greens are easier to hit from the fairway than from the rough.
- Practise approach shots at set distances, for example 80, 100 and 120 metres, and note how often the ball lands on the green.
Above all, measure your dispersion. A ball that always finishes five metres left of the target is easier to correct than a ball that flies left one time and right the next. A coach can work with you to find out whether swing, alignment or club choice is holding your percentage back.
Try it at Golf Lounge
To hit more greens you need to know how far your approach shots really go. At Golf Lounge Resort Hamburg, TrackMan III measures the ball flight by radar, at every hitting bay on the range and in the simulator boxes. You see values such as carry distance, launch angle, ball speed and spin, and so find out how far your 7 iron actually flies. The range has 32 hitting bays on two levels. V1 Pro video analysis is available as a complement.
Frequently asked questions
What does greens in regulation (GIR) mean in golf?
GIR means you hit the green in the expected number of strokes: par minus two. That is one stroke on a par 3, two on a par 4 and three on a par 5. It is enough if part of the ball touches the putting surface. The figure shows how good your approach play is.
How do you calculate the GIR percentage?
You divide the number of greens hit by the number of holes played. Twelve greens on 18 holes is about 67 per cent. Some players track the figure per round, others over several rounds. For a reliable value the average of several rounds is worth using.
Does a ball on the fringe count as a green in regulation?
No. A green only counts as hit if the ball touches the putting surface. A ball on the fringe is not a GIR. Some statistics therefore also show greens or fringe in regulation so that near misses become visible.
What is a good GIR percentage?
PGA Tour players hit a little over 65 per cent of greens on average, and the best around 70 per cent. For amateurs every increase is progress. Going from a few greens per round to several usually means clearly better scores. The percentage also depends on the course.
What matters more, GIR or putting?
They belong together. Hitting many greens gives you many chances for par and birdie. Putting decides how often those chances turn into a good score. For beginners it is worth looking at both figures, because then you can see whether strokes are lost on the way to the green or on the green.
