What Is GIR in Golf? Greens in Regulation Explained

GIR stands for greens in regulation, and it counts how often you reach the putting surface in the expected number of strokes, which is par minus two. That means the green in one on a par 3, in two on a par 4, and in three on a par 5, always leaving two putts for par. It is the single stat that best predicts your score, because reaching greens in regulation is what gives you birdie and easy par chances.

Track one number to understand your game, and greens in regulation is the one to track.

What greens in regulation actually means

The “regulation” figure is built from the idea that par allows two putts. Subtract those two putts from par and you get the number of shots you are supposed to need to reach the green. Hit the surface in that many strokes or fewer and you have a GIR.

Worked out by hole:

• Par 3: on the green in 1 stroke.
• Par 4: on the green in 2 strokes.
• Par 5: on the green in 3 strokes.

The ball only has to be on the putting surface, not close to the hole. A 60-foot GIR counts exactly the same as one to three feet. The point of the stat is to isolate your long game, tee to green, from your putting.

GIR and FIR: the two regulation stats

GIR has a partner, FIR, which stands for fairways in regulation. FIR measures whether your tee shot finds the fairway on par 4s and par 5s (par 3s are excluded because you are aiming at the green, not a fairway). The two stats work as a chain: FIR tells you how well you drive it, GIR tells you how well you drive and approach combined, and putts per round finish the story. Weakness in one usually explains a run of bogeys better than a general sense that you “played badly.”

What a good GIR is by handicap

Expectations should scale with ability. The figures below draw on published amateur datasets from Shot Scope and Arccos, which track millions of real rounds, alongside PGA Tour averages. Treat them as typical, not exact.

Player level	Greens in regulation per round	Percentage
PGA Tour average	12 to 13	65 to 70%
Scratch (0 handicap)	10 to 11	55 to 60%
5 handicap	7 to 8	39 to 44%
10 handicap	4 to 5	25 to 30%
15 handicap	3	17%
20 handicap	2	11%

The steep drop from scratch to a 10 handicap is the clearest picture of where amateur golf is won and lost. It is not that mid-handicappers cannot putt; it is that they reach far fewer greens and scramble for the rest.

Why GIR predicts your score so well

Every green you hit in regulation is a hole where two putts guarantee par and one putt makes birdie. Every green you miss forces a chip or pitch just to save par, and that recovery fails more often than it succeeds for most golfers. So GIR does not just measure ball-striking; it measures how many stress-free pars you set up before you ever pull a wedge.

That is why touring pros obsess over it and why the gap between a 15 handicap and a scratch player is mostly a GIR gap, not a putting gap. Improve your greens hit by two or three per round and your scores fall even if nothing else changes.

How to raise your GIR

The fastest gains come from honesty about distance. Amateurs routinely miss greens short because they overclub their own carry numbers. Knowing your true carries and building a reliable golf club distances chart lets you take enough club to reach the middle of the green rather than the front edge you rarely clear.

Aiming at the fat of the green rather than the flag matters too. A shot at the centre turns a slightly pushed approach into a 30-foot GIR instead of a missed green in the bunker. Pair that with the kind of course management that also protects a good golf score, and your GIR climbs without any new swing at all.

The number worth chasing

Greens in regulation is reaching the green in par minus two, and it is the stat most tightly linked to how you score. Aim for the middle of the green, know your real carry distances, and watch the number rise. Start counting your GIR next round and you will quickly see whether your scores are made in the long game or lost in the short one.
