Everything You Need to Know About Green in Regulation (GIR)

Updated On December 13, 2023

Green in Regulation (GIR) is an essential metric for golfers looking to improve their game and measure their performance on the course. It evaluates a player’s ability to reach the green within the designated number of strokes, considering factors such as distance, accuracy, and course conditions.

By understanding and tracking GIR, golfers can identify areas of strength and weakness, ultimately enhancing their strategy and increasing their chances of success. 

Why Are Greens in Regulation Percentages So Important?

Greens in Regulation (GIR) hold immense importance in the world of golf for several key reasons:

Performance Indicator: GIR serves as a reliable performance indicator, reflecting a golfer’s ability to reach the green with accuracy and precision. A higher GIR percentage often correlates with better scores and a more consistent game.

Course Management: Understanding GIR helps players identify areas where they can improve their course management. By analyzing GIR data, golfers can make informed decisions on club selection, shot execution, and strategic adjustments to navigate golf courses more effectively.

Ball Striking Skills: A high GIR percentage often indicates strong ball striking skills, which is crucial for success in competitive golf. Improving GIR can boost players’ confidence and help them develop a well-rounded game.

Short Game Relief: Players consistently hitting a GIR puts less pressure on their short game, as they are more likely to have easier putts for birdie or par. This can lead to lower scores and less stress during play.

Comparison with Peers: GIR allows golfers to compare their performance with peers and professionals, offering valuable insights into areas needing improvement. Monitoring GIR statistics can also foster motivation and friendly competition among fellow golfers.

When is a golf ball considered on the green?

A golf ball is considered on the green when it comes to rest on the putting surface of the hole being played. The putting surface is typically a smooth, well-manicured area of grass surrounding the hole. Once the ball is on the green, the golfer can use a putter to attempt to roll the ball into the hole. It’s important to note that if the ball is on the fringe or apron (the closely mown area immediately surrounding the green), it is not considered on the green, and the player may choose to use a putter, wedge, or other clubs to approach the hole.

How Do We Calculate Greens in Regulation?

Greens in Regulation is calculated by dividing the number of greens a golfer reaches in regulation by the total number of holes played. For example, if a golfer plays 18 holes and reaches 12 greens within the designated strokes, their GIR percentage would be 12/18 * 100 = 66.67%.

GIR by handicap – Greens in Regulation stats

Understanding how Greens in Regulation (GIR) percentages vary across different handicap levels can provide valuable insights into your own performance and help set realistic goals for improvement. 

Greens in Regulation percentage by handicap level

GIR percentages typically increase as a golfer’s handicap decreases. Here’s a rough breakdown of the average GIR percentages based on handicap levels:

Low Handicap (0-5): Around 50-65% GIR

Mid Handicap (6-15): Approximately 30-50% GIR

High Handicap (16+): Roughly 10-30% GIR

These figures are not absolute but serve as a general guideline for golfers to assess their performance and set achievable targets for improvement.

Final Thoughts

In conclusion, focusing on Greens in Regulation (GIR) is a key factor in elevating your golf performance and achieving lower scores. A higher GIR percentage reflects improved ball striking, better course management, and increased consistency – all essential components of a successful golfer.
