The GIR Definition — Hole by Hole
The regulation number of strokes is always par minus two. The logic: two putts are assumed to make par from anywhere on the green, so any shot that reaches the green and still leaves two putts to make par qualifies as a GIR.
One important rule: the ball must be on the putting surface itself. The fringe — the thin strip of slightly longer grass surrounding the green — does not count as a GIR, even though most golfers choose to putt from it. This is one of the most common sources of confusion about the stat.
Does the fringe count as a GIR?
No. Your ball must be on the putting surface — not the fringe, collar, apron, or rough around the green. Even if you decide to putt from the fringe, the hole does not count as a green in regulation.
How to Calculate Your GIR Percentage
Tracking GIR is simple. After each hole, mark whether you hit the green in regulation with a circle or checkmark on your scorecard. After 18 holes:
- Count the total number of holes where you hit the green in regulation
- Divide by 18 (or however many holes you played)
- Multiply by 100 to get your GIR percentage
Example: You hit 6 greens in regulation in an 18-hole round. 6 ÷ 18 × 100 = 33% GIR.
You can also calculate GIR on the course in real time by asking: have I reached the green and still have two putts to make par? If yes, you have a GIR. If you've already used more shots than par minus two to get to the green, the hole is already out of regulation before you even putt.
GIR Targets by Handicap
This is where GIR becomes genuinely useful for your game. Rather than comparing yourself to tour professionals, compare your GIR to what golfers at your handicap level actually achieve. The data below comes from Arccos, which has tracked over 600 million golf shots across 13 million rounds.
| Handicap | Avg GIR per round | GIR % | Benchmark |
|---|---|---|---|
| PGA Tour | 11–12 | ~65% | Professional baseline |
| Scratch (0) | 10–11 | ~58% | Elite amateur |
| 5 handicap | 8 | ~44% | Low handicapper |
| 10 handicap | 6 | ~33% | Mid handicapper |
| 15 handicap | 4–5 | ~22–28% | Average club golfer |
| 20 handicap | 3 | ~17% | Higher handicapper |
| 25+ handicap | 2–3 | ~16% | Beginner / developing |
The gap in the table is striking. A 5-handicapper hits almost three times as many greens per round as a 25-handicapper. Each extra GIR is a birdie opportunity and one fewer scrambling situation — and scrambling drains strokes fast.
Why GIR Is the Most Important Golf Stat
GIR has the strongest correlation to handicap of any traditional golf statistic. The logic is direct: every green you hit in regulation gives you two putts to make par and one putt to make birdie. Miss the green and you're chipping or pitching — a significantly harder task — just to save par.
High-handicap golfers are constantly scrambling because they miss greens. Low-handicap golfers score well because they consistently give themselves birdie putts. Tracking GIR doesn't just tell you your score — it tells you why your score is what it is and exactly where to direct your practice.
GIR vs Strokes Gained — which should you track?
GIR is a simple, intuitive yes/no stat per hole. Strokes gained is more precise — it accounts for shot distance and difficulty on every single shot. For most recreational golfers, GIR is the better starting point: it's easy to track on a scorecard, highly correlated to handicap, and immediately actionable. Once you're below a 10 handicap, strokes gained gives you deeper insight. Track both if you can.
How to Improve Your GIR
Every extra GIR per round is worth roughly half a stroke off your score. Here are the most effective ways to hit more greens:
GIR and FIR — Two Stats Worth Tracking Together
FIR stands for fairway in regulation — it tracks whether your tee shot lands in the fairway on par-4s and par-5s (par-3s are excluded since you're aiming for the green). GIR and FIR are highly correlated: hitting more fairways almost always leads to hitting more greens.
Analyzing both together reveals exactly where your game breaks down:
- High FIR, low GIR: Your tee shots are solid but your iron play needs work — approach shot accuracy is the issue
- Low FIR, low GIR: Fix driving accuracy first — everything else follows from the tee
- Low FIR, high GIR: Your scrambling and recovery shots are excellent — unusual but encouraging
