Greens in Regulation
A green in regulation, usually shortened to GIR, is when a golfer reaches the putting surface in the number of strokes equal to par minus two. It is one of golf’s oldest performance stats and one of the clearest indicators of solid ball-striking.
What is a green in regulation?
The shorthand is simple: par minus two. Every hole on a golf course has a par number, and that par assumes the player will need two putts once on the green. Subtract those two putts from the total, and the remaining strokes are what a player has to reach the putting surface in regulation.
So on a par 4, a player has two strokes to find the green. On a par 3, just one. The point of the stat is to isolate ball-striking from putting. A player who lands the ball on the green within the regulation count has done the harder part of scoring well: getting from tee to green efficiently. What happens next is a putting question, not a ball-striking one.
The PGA Tour has tracked GIR as an official statistic since 1980, and Jack Nicklaus led the tour the year it was introduced. Today, the stat is used at every level of the game, from professional tours to weekend players using a phone app to log rounds.
GIR by hole type
Because GIR is tied to par, the threshold changes depending on the hole. The breakdown is straightforward.
| Hole type | Strokes to hit GIR | Example |
|---|---|---|
| Par 3 | 1 stroke | Tee shot finds the green |
| Par 4 | 2 strokes or fewer | Drive plus approach |
| Par 5 | 3 strokes or fewer | Drive, layup, and approach |
| Par 6 | 4 strokes or fewer | Rare; same par-minus-two rule |
Hitting the green in fewer strokes than the regulation count still counts. Driving the green on a short par 4 in one shot, for example, is recorded as a GIR. The same applies to reaching a par 5 in two. Par 6 holes are uncommon but do exist on a handful of courses, and the same par-minus-two rule applies.
What counts and what does not
For a shot to count as a GIR, the ball has to come to rest on the actual putting surface. The fringe and apron around the green do not qualify, even though they sit right alongside it. According to the PGA Tour’s definition, any portion of the ball touching the putting surface after the GIR stroke is enough to qualify, but a ball sitting fully on the fringe does not count, even if it is two inches from the edge.
This rule frustrates plenty of golfers because a ball just off the green can be much easier to two-putt than one sitting 80 feet away on the green itself. The stat does not care about proximity to the hole. It only cares about whether the ball is on the putting surface within the regulation stroke count.
Penalty strokes also count toward the GIR total. If a player drives into a water hazard on a par 4, takes a penalty drop, and then hits the green, that is three strokes, one too many for a GIR.
How to calculate GIR percentage
Tracking GIR over a round or a season makes more sense as a percentage than as a raw count. The formula is:
GIR % = (Greens hit in regulation ÷ Total holes played) × 100
A player who hits 6 greens out of 18 holes has a GIR of 33.3% for that round. The same formula works for a 9-hole round: divide the greens hit by 9 and multiply by 100. Most golf scorecards leave a column for tracking GIR alongside fairways and putts, and most stat-tracking apps log it automatically.
Average GIR by skill level
Skill level shows up clearly in GIR data, and the gap between handicap brackets is wide. Data from Break X Golf, drawn from 3,788 rounds across 1,116 golfers, shows the spread:
| Handicap | GIR percentage | Greens per round (approx.) |
|---|---|---|
| Scratch | 56.8% | 10 |
| 5 | 46.1% | 8 |
| 10 | 37.3% | 6.7 |
| 15 | 26.4% | 4.7 |
| 20 | 22.4% | 4 |
| 25 | 18.7% | 3.4 |
Other large data sets agree on the broad pattern. Shot Scope reports the typical 10-handicap hits 6.3 greens per round, and the average 15-handicap hits 4.14. Golfshake’s data on a 15-handicap median player puts the figure at 5.22 greens per round (22.77%).
The PGA Tour average sits between 65% and 68%, depending on the season. The 2025 PGA Tour leader was Michael Thorbjornsen at 73.56%, with Patrick Fishburn (74.21%) and Scottie Scheffler (74.47%) leading the previous two seasons. The highest single-season figure since the stat became official belongs to Tiger Woods, who hit 75.15% of greens during his 2000 campaign.
The four-round tournament record is 69 greens out of 72, shared by Peter Jacobsen at the 1995 AT&T Pebble Beach National Pro-Am and Jerry Kelly at the 1996 Walt Disney World/Oldsmobile Classic.
GIR vs. fairways in regulation
Plenty of golfers confuse GIR with FIR (fairways in regulation), which counts how often a player’s tee shot finds the fairway on par 4s and par 5s. Par 3s do not factor into FIR.
The two stats measure different parts of the game. FIR is about driving accuracy. GIR is about approach play and overall ball-striking. GIR also has a stronger statistical link to scoring: hitting more greens correlates more directly with lower handicaps than hitting more fairways does, because finding the green creates a chance for par or better, while finding the fairway only creates a chance to find the green.

Frequently Asked Questions
Does the fringe count as a green in regulation?
No. Even though many golfers putt from the fringe, the ball must come to rest on the actual putting surface for the shot to count as a GIR. Landing on the collar or apron does not qualify.
What is a good GIR percentage for an amateur?
For most amateur golfers, anything above 33% (about 6 greens per round) is a strong figure. Single-digit handicaps tend to hit 40-50% or more. Anything in the 50% range puts a player in scratch territory.
Does driving the green on a par 4 count as a GIR?
Yes. Reaching the green in any number of strokes at or below the regulation count is a GIR, including a drive that finds and stays on a short par 4 green.
Who has the PGA Tour record for GIR percentage in a season?
Tiger Woods, with 75.15% during the 2000 season. That mark has stood since the start of his historic year and remains the highest figure recorded since the PGA Tour began tracking the stat in 1980.
Do penalty strokes count toward GIR?
Yes. Every stroke counts, including penalty shots. A player who hits into a hazard, takes a drop, and then finds the green has used those three strokes against the GIR threshold.
