In golf, a green in regulation (GIR) is a statistic that measures a golfer's performance. It is achieved when a golfer gets their ball onto the putting green in two strokes fewer than the par of the hole. The par number for a hole includes two putts, so achieving a GIR gives a golfer two putts to make par. GIR is an important statistic for golfers of all skill levels as it is highly predictive of a golfer's score and handicap. Tracking GIR stats can help golfers identify areas for improvement and set benchmarks for their game.

| Definition | A "green in regulation," often abbreviated GIR, is a statistical category on the professional golf tours, as well as a popular method for amateurs and recreational players to rate their rounds. |
| Objective | The objective is to get the ball in the hole with the least number of strokes and getting "greens in regulation" is the best way to do this. |
| Par | Each hole has a predetermined number of strokes (every time you hit it counts as 1) from the tee box to the cup (in the hole) this is called PAR. Most courses are made up of par 3's, 4's, and 5's. |
| GIR Strokes | On a par-3, the first stroke; on a par-4, the second stroke; on a par-5, the third stroke. |
| GIR Statistic | A green in regulation (GIR) is a golf statistic that measures whether or not your ball finishes on the green in two strokes fewer than the par of the hole. |
| GIR Percentage | A scratch golfer hits 59% of their greens in regulation on average, while a 25-handicapper hits only 9%. |
| PGA Tour Record | The PGA tour record is 69 out of 72 holes in a tournament. |

Greens in regulation (GIR)
Each hole on a golf course has a predetermined number of strokes, or 'par', which includes two putts on the green. A golfer is considered to have achieved GIR when any part of their ball is touching the putting surface, and the number of strokes taken is at least two fewer than the par for that hole. For example, on a par-4 hole, a golfer's first stroke is from the tee box, and the second stroke, known as the approach shot, would ideally land on the green, counting towards a GIR.
GIR is one of the most important statistics in golf, highly predictive of a player's score and handicap. It is a key differentiator between low, mid, and high-handicap players. A scratch golfer, for instance, hits 59% of their greens in regulation on average, compared to just 9% for a 25-handicapper.
To improve their GIR, golfers can work on their accuracy and distance off the tee, as well as their iron play. This can be achieved through speed and distance training, as well as seeking guidance from a golf instructor.

Par and scoring
Par is a fundamental concept in golf that dictates the strategies used throughout the game. Each hole on a golf course is assigned a "par" score, representing the number of strokes an expert golfer is expected to need to complete the hole. Par can vary by hole and course, typically ranging from 3 (par-3) to 5 (par-5), with the total par for 18 holes usually being around 72 strokes for a standard course.
Golf courses feature three main types of holes, each with its own par value: Par 3, Par 4, and Par 5. On a Par 3 hole, golfers are expected to reach the green in one stroke and sink the ball with two putts. These holes range from 100 to 250 yards for men and under 220 yards for women, testing accuracy and putting skills. Par 4 holes, which can be over 500 yards long, require golfers to reach the green in two strokes and make two putts to complete the hole. The longest holes, Par 5s, are designed for golfers to reach the green in three strokes, although professional golfers often aim for two strokes to add excitement to the game.
Understanding par is crucial for crafting a successful golf strategy. Each hole's par sets expectations, and adjusting your strategy based on the hole's par will help maximise your performance. For example, on Par 3 holes, focus on precision; on Par 4 holes, balance challenge and strategy; and on Par 5 holes, aim for power and distance.
Golf scoring introduces colourful terminology to describe performance relative to par. Achieving a score of one stroke under par on a hole is called a "birdie," while two strokes under par is an "eagle." An albatross or double eagle refers to three strokes under par, and a condor is a hole-in-one on a Par 5. Conversely, a score of one stroke over par is a "bogey," and two strokes over par is a "double bogey." These terms add a layer of excitement and achievement to the scoring process, motivating players to strive for lower scores.
Additionally, golf utilises a handicap system to ensure fair competition among players of varying skill levels. A handicap is a numerical measure of a golfer's ability, calculated based on recent scores and adjusted for course difficulty. Lower-handicap players are expected to have a higher likelihood of scoring closer to par than higher-handicap players. By tracking their handicap and GIR (greens in regulation) percentages, golfers can work towards improving their performance and lowering their scores.

Tracking your GIR stats
Golf is a game that relies on a lot of different variables, and tracking your progress can be difficult. Tracking your GIR stats is a great way to monitor your performance and set goals for improvement.
GIR, or "greens in regulation", is a golf statistic that measures whether your ball finishes on the green in two strokes fewer than the par of the hole. For example, on a par 4 hole, your first stroke is from the tee box, and the second stroke is an approach shot. If this second stroke lands on the green, it counts towards a GIR.
There are several ways to track your GIR stats. Firstly, you can use a golf stat-tracking app, such as 18Birdies, which offers real-time stat monitoring and automated data collection. The GHIN app is another popular choice for tracking GIR, as it allows you to mark the direction of your shots and see how well you're hitting your approach shots. You can also use a complete on-course game-tracking system like Shot Scope, which is considered the global leader in on-course stat tracking.
Additionally, some golfers prefer to use a golf journal or spreadsheet to track their GIR stats. This method allows you to organize your data in a way that works best for you and helps you identify patterns in your performance. For instance, you can track the distance of your approach shots, the location of the pin, the club used, and whether you hit or missed the green.

Improving accuracy
In golf, a "green in regulation", often abbreviated to GIR, is a statistical category that measures a golfer's performance. A GIR is achieved when a golfer gets their ball onto the putting green in two strokes fewer than the par of the hole. For example, on a par-4 hole, a golfer would need to get their ball onto the putting surface in two strokes to achieve a GIR.
GIR is an important statistic in golf because it is one of the biggest differentiators between low, mid, and high-handicap players. A scratch golfer hits 59% of their greens in regulation on average, while a 25-handicapper only hits 9%. Therefore, improving one's accuracy and increasing their GIR percentage is key to improving one's golf game and shooting lower scores.
To improve accuracy and increase your GIR percentage, it is important to first identify your current swing and game. The best way to address this is through the help of a golf instructor, who can help you determine the areas you need to work on. If you are consistently missing greens due to errant tee shots, improving your driving accuracy off the tee can help you hit more greens in regulation. This can be done by selecting the right club to hit from the tee box, such as choosing a club that gives you confidence. Additionally, working on your iron play can also improve your accuracy, as irons are the clubs most often used when hitting or missing a GIR.
Another way to improve your accuracy and GIR percentage is to focus on distance control. Hitting the ball farther off the tee can increase your chances of hitting greens in regulation, but it is important to maintain a high level of accuracy. PGA tour players like Tiger Woods and Rory McIlroy balance distance with supreme short-game skill, allowing them to hit the green with their second stroke or be green side in two. Therefore, it is important to not sacrifice your short game and touch on the putting green in favour of distance alone.

Club selection
Par 3s: On shorter holes, such as par 3s, the complexity of the shot is reduced, and even novice golfers have a good chance of achieving a GIR. In these instances, club selection is typically limited, and a shorter club is often the preferred choice. By teeing the ball up, you can make cleaner contact, increasing the likelihood of reaching the green with your first shot.
Par 4s: On a par 4, an expert player is typically expected to use two shots to reach the putting surface. The first stroke is the drive, followed by an approach shot into the green. Selecting the appropriate club for the drive is critical. Most golfers make the mistake of choosing the wrong club to hit from the tee box, so opt for a club that gives you confidence. Improving your accuracy off the tee will enhance your chances of achieving a GIR.
Par 5s: For par 5s, achieving a GIR in two strokes is more challenging. Professional golfers, such as Tiger Woods and Rory McIlroy, can reach the green in two strokes due to their ability to balance distance with short-game skill. As an amateur golfer, you may need to adopt a different strategy. Focus on achieving good accuracy and distance control to increase your chances of hitting the green in three shots.
Iron Play: Irons are the clubs most commonly used when approaching a GIR. If you consistently fall short of achieving a GIR, it may be beneficial to work on your iron play with the guidance of a golf professional. Improving your iron play will provide you with the skills and confidence needed to make those crucial shots that determine a successful GIR.
Distance and Accuracy: Achieving a balance between distance and accuracy is essential. Increasing your driving distance can be advantageous, but it should not come at the cost of sacrificing your short game. Focus on maintaining a high level of accuracy while gradually working on improving your distance through dedicated training routines.
