Among the many techniques employed by golfers, the Rule of 12 stands as a powerful tool for honing their short game. 

The Rule of 12 is a simple yet effective method that golfers employ to estimate the distance their ball will roll when executing shots around the greens. It provides a guideline for choosing the right club and making precise adjustments for different situations. 

This blog post delves into the intricacies of the Rule of 12 and how it can help you become a more proficient golfer around the greens. 

What is Rule of 12 In Golf?


The Rule of 12 in golf is a technique used by golfers to help them choose the appropriate club to use when hitting a short shot around the green. 

It involves taking the distance from the ball to the hole and subtracting it from 12 to determine the desired landing spot of the ball on the green. 

For example, if the ball is 10 feet away from the hole, subtracting 10 from 12 gives a result of 2, indicating that the ball needs to land approximately 2 feet onto the green to reach the hole.

By using this technique, golfers can ensure that they choose a club that will allow them to hit the ball the appropriate distance and achieve the desired result. 

It is particularly useful for shots where there is little room for error, such as when the ball is close to a bunker or water hazard. 

The Rule of 12 is easy to remember and can be a helpful tool for golfers of all skill levels to improve their short game.

How Do You Calculate The Rule Of 12 In Golf?

The Rule of 12 in golf is a simple technique used to estimate how much a golf ball will roll on the green after landing.

It helps golfers make more accurate judgments when choosing a club and planning their shots around the green. 

Here’s how you can calculate the Rule of 12:

Step 1: Assess the Distance

Stand on the green and assess the distance between your ball and the hole. You can use your feet, strides, or a rangefinder to estimate the distance accurately.

Step 2: Determine the Stimp Rating

The Stimp rating refers to the speed of the green. It is a measure of how fast the ball rolls on the putting surface.

The average Stimp rating is around 10-11, but it can vary depending on the golf course and its conditions. 

If you’re unsure about the Stimp rating, you can ask the golf course staff or fellow golfers for an estimate.

Step 3: Divide the Stimp Rating by 12

Take the Stimp rating and divide it by 12. For example, if the Stimp rating is 10, dividing it by 12 gives you approximately 0.83.

Step 4: Calculate the Estimated Roll

Multiply the result from the previous step by the distance you assessed in Step 1. This will give you an estimation of how far the ball will roll on the green. 

For example, if you assessed a distance of 20 feet and the Stimp rating is 10, the calculation would be: 0.83 (Stimp rating divided by 12) multiplied by 20 (assessed distance) equals approximately 16.6 feet of roll.
