What Does the Slope Rating of a Golf Course Mean?

Despite golf being such an accessible sport, it’s full of jargon that can confuse a simple round on the green. If you’re not getting used to the names of equipment, shots, or phrases like “fore”, you’ve got the enigmatic slope score to understand.

However, don’t let this overwhelm you. While it might initially seem like a random number, the slope rating of a course is there to help and guide you so you know what to expect from your round on the green. 

Read on to discover what it means and why it’s so essential. 

What Is a Golf Course Slope Rating?

A slope rating differs from a score such as a film review; it’s a mathematical measurement assessing the difficulty of a golf course. Many factors go into this rating, including the USGA par rating and the predicted score of a handicapped golfer. 

So before you visit a green, you can assess how challenging it will be. Typically, a course rating lets you scratch golfers (who typically shoot at or better than par) how tricky the course will be. Meanwhile, the slope rating informs the bogey golfers how challenging the course will be. 

Generally speaking, bogey players reference players who get an average bogey score. Still, under the USGA, a bogey player has a handicap index of approximately 20 for men and 24 for women. 

What Is an Easy Slope Rating?

It’s all well and good knowing that a slope rating determines the difficulty of a golf course, but what’s the use of that if you can’t understand the score itself? When you arrive at the course, the first thing to do is check the scorecard, which will tell you the slope rating (usually printed on it). 

Every tee box will have a different score, and the average rating of a course is typically 113. If the green is less than 113, you know it’s easier than the middle green. 

What Is a Hard Slope Rating?

Remembering 113 is important because once that number sticks in your mind, you can assess if you’re on a more challenging green should the rating be higher than 113. If your course is higher than 113, don’t panic and think you won’t be able to complete it. 

Either see it as a good challenge or play the green from the forward tee boxes to make it easier for yourself. 

How Is Slope Rating Calculated for a Golf Course?

The slope score is a mathematical calculation and is slightly different for men and women. For men, it’s 5.381 x Bogey rating minus the USGA course rating, whereas for women, it’s 4.24 x Bogey rating minus the USGA course rating. 

Remember that course rating differs from slope score, as that is a difficulty measured for scratch golfers and is done via strokes. If you’re wondering whether you’re a scratch or bogey golfer, chances are you’re the latter. But if in doubt, you can check your golf score. Yet, the USGA only class 1% of all amateur golfers as scratch golfers, so there are two different calculations. 

It’s not just anybody who can do this calculation, however. You need to be a professional course rater, as hundreds of variables are used to determine this rating, including length, hazards, roughness, topography, and obstacles such as trees. If the process sounds complicated, that’s because it is, but the rating itself is easier to understand. 

Why Is Slope Rating Important?

Ultimately, slope score is essential to understand so that you know, before stepping foot on the green, how challenging the round will be. It’s crucial to understand this so that if your progress isn’t as good as the last time you played, you can assess if this is down to the difficulty of the course or not. 

Frequently Asked Questions

What Does a Slope Rating of 130 Mean?

The average difficulty of a course is 113. If you’re playing on a 130 course, you know that round will be considerably more complicated than a 113 or less course. This allows you to push yourself and be aware of the challenge. 

Is a Higher or Lower Slope Rating Harder?

The higher the score, the more complex the course. However, that being said, it’s important to remember that the average difficulty is 113. So if you’re playing a course that is 100, while that’s a high number (generally speaking), it’s an easier-than-average course. 

Final Thoughts

Slope ratings and course ratings can get confusing. But for the 99% of golfers out there, you want to note the slope rating (not the course rating). Some golfers will want to know this in advance to determine if they wish to give the course a go, while others will want to know so they can factor the slope number into their overall performance analysis. 

Whatever the score, it’s always best to be prepared out on the green. So why not discover Stitch Golf’s gear and apparel so that you have everything you need for the perfect round?
