What does slope rating really mean for a golf course?
The slope rating of a golf course is a measure of its difficulty for bogey golfers. The term comes from the likelihood that when playing on more difficult courses, players’ scores will rise more quickly than their handicaps would predict. The “slope rating” of a course thus predicts that rise.
What is golf slope rating and how is it determined?
How to Calculate Slope Rating
- Use the Bogey Rating of the course. Ask at the golf course or contact the regional golf association that did the on-site rating.
- Locate the USGA Course Rating. The rating for each set of tees is usually on your scorecard, or you can ask staff at the course for this information.
- Subtract the Course Rating from the Bogey Rating. ...
How is the slope of a golf course determined?
Slope rating takes into account the USGA par rating of the course as well as the expected score of a higher handicap golfer. The difference between the two multiplied by 5.381 is the calculation used to determine the mens slope rating for a golf course.
How do you calculate golf handicap and slope?
Handicap differential = (Adjusted Gross Score-rating of the course) X 113 / Course slope ratings. The course rating is simply the scores of a new golfer on a normal course under a normal playing condition. Slope rating is the rating of 113 for a course based on the standard difficulty.
Is a 130 slope rating hard?
If you see a slope rating that falls anywhere in the double digits, you can expect that course to play rather easy, even for a bogey golfer. On the other hand, taking on a course with a slope rating in the 130's or 140's is going to present a serious challenge to a player with a mid or high handicap.
How do I calculate my 2021 course handicap?
The Course Handicap formula: Handicap Index x (Slope Rating of Tees Played/113) + (Course Rating - par). For example, your Handicap Index is 16.7 and the tee box slope is 127, the course rating is 70.5 and par is 72.
What determines Slope Rating?
Playing length and obstacles impact higher-handicap players more than lower-handicap players, and Slope Rating measures the relative difficulty of a golf course for players who are not scratch players compared to those who are scratch players. It is determined by comparing the Course Rating™ to the Bogey Rating™.

What is Slope Rating?
Slope Rating is described by the USGA as demonstrating the “measurement of the relative playing difficulty of a course for players who are not scratch golfers, compared to scratch golfers”. The higher a course’s Slope Rating, the higher the expected difference of scoring between a scratch golfer and a bogey golfer.
How is Slope Rating Calculated?
To determine the Slope Rating for a course requires two key numbers – Course Rating and Bogey Rating. The Course Rating is the evaluation of the playing difficulty of a golf course for the scratch player (0 handicap.) The Bogey Rating is the evaluation of the difficulty of a course for a bogey player of 20-24 handicap.
What Does a Slope of 113 Mean?
113 is the average Slope Rating signifying a course of standard relative difficulty. The number 113 is used in calculating a player’s Course Handicap. Each player with a WHS Handicap Index can calculate their Course Handicap for any course by dividing the Slope Rating of that course by 113 and multiplying that number by their Handicap Index.

What does slope number mean in golf?
Thus, the slope number converts a golfer’s handicap into a course handicap. In this way, it is made sure that a bogey golfer is allowed to play at an equal level to a scratch golfer, and it helps them obtain enough strokes from the same set of tees. This is the mathematical formula of how it is derived:
What is USGA rating?

When did the slope rating start?
USGA introduced the slope rating measurement in the 1980s as a system of fairness directed to bogey players. Namely, they observed that a bogey golfer is likely to increase the number of strokes considerably more when playing on a course with a higher level of difficulty than a scratch golfer. This led to creating a slope handicap system ...
Do golf courses affect the slope number?
Yes, they do. However, the course rating impacts the golfer’s index considerably more than the slope number. It often happens that players become too focused on the slope number while ignoring the golf course number.
Course Rating
Course rating is one of the foundations of the golfing handicap system. Without course rating, players wouldn't be able to post scores or maintain a handicap index.
Many Many Features
The features of a golf course that the course rating team have to measure include:
Thousands of Figures
There are generally a set of 26 evaluations applied to each set of tees on each individual hole.
Taking Stimps
In order to work out the speed of a putting green, a simple tool called a Stimpmeter is used.
Now for Some Algebra
If you cast your mind back to your High School algebra classes (sorry...but this bit is important!) you will remember that the slope of a line is a function of its length and its height.
Golf Course Slope Rating
The first use of slope is essentially a measure of how difficult a course is relative to others. You might be playing on a par 72, but that doesn’t make it as much of a challenge as say, Augusta National and its par 72. A slope number simply allows you to know, at least to some extent, what the difference really is.
How is Golf Course Slope Calculated?
Well this is all well and good, but how is this number calculated? Well technically, the number represents how much more difficult a given set of tees is for a bogey player in relation to scratch handicapper. You might think that this difference is fairly constant, but that isn’t the case at all.
Who Rates the Course?
There is obviously a deal of subjectivity in this rating. After all, golf isn’t an exact science.
Rangefinder Golf Slope Explained
This might seem relatively straightforward, at least in theory, but this is when we hit problem. Slope is also used to mean something completely different. Confusing, right? Slope is part of a variable when calculating distance as I explained in another article.
Calculating Distance with Slope
This is where our second definition of slope comes into play. You may have heard of a slope function on a rangefinder. This gives you an adjusted yardage based on the difference in elevation between where you are and where you want to go by using some fancy tech to essentially give an angle up or down which is used to adjust the distance.
What is slope rating?
The Slope Rating reflects the relative difficulty of a course for players who are not scratch golfers in comparison to scratch golfers. Golfers use the Slope Rating, a trademark of the United States Golf Association, to calculate handicap differentials. The rating falls between 55 and 155; the higher the number, the more challenging the course.
Do golfers have access to slope ratings?
Golfers typically don't have access to the information used to calculate the Slope Rating, but understanding the formula makes the rating less confusing.
Why is it important to know the slope of a golf ball?
This is because, while you may calculate the distance between you and the flag in a straight line, you do not hit the ball in a straight line. The ball is hit at an arc and with a trajectory that effects how far it actually goes.
What does it mean when you walk uphill or downhill?
Anytime you walk uphill or downhill you are walking up or down a slope. Think of triangle on its side and you’ll see a slope. On the course, we deal with this all the time because a shot that goes from one point to another that is at the same height is the exception rather than the rule.
Can a rangefinder be used in a golf tournament?
According to Appendix IV of Rule 14-3 no measuring device that calculates for slope may be used during tournament play. This does not mean, however, that your rangefinder cannot be used at all. The USGA does allow for a Local Rule to permit a “stipulated round” in which measuring devices like rangefinders can be used.
Does not taking slope into account hurt your score?
But we can certainly say that failing to account for slope will certainly hurt your score. This is because you will likely be under or overhitting the ball. As you get better with adjusting and factoring in slope, you should see some improvement in your overall score.
Can GPS calculate slope?
While GPS might be able to give some indication of your relative elevation, it won’t be able to calculate slope for your specific situation. This doesn’t make it useless, but means that a course with a lot of height changes will reduce its effectiveness quite a bit.
Can a GPS track slope?
So, a GPS device will not be able to calculate for slope, but only estimate your distance to different predetermined locations on the course.
Is it harder to play golf without knowing the slope?
What is clear is that playing without knowing the slope is a whole lot harder. This also depends on how much the course you play changes in elevation. A relatively flat course will not factor in much slope at all. On very hilly courses, failing to factor for slope could cost you dozens of strokes.
What is a rating of slope?
A rating of slope in contrast, is a number (typically between 55 and 155) describing the relative difficulty of a course for a bogey golfer compared to a scratch golfer.

How does weather affect golf scores?
Since golf is a game that is played outdoors, weather or other conditions can significantly affect a player's scores. As such, in an effort to more accurately represent a player's scores, an adjustment, referred to as the Playing Conditions Calculation (PCC), based on playing conditions for the course is included. This involves factoring in a number, ranging from -1 (when conditions make the course easier) to 3 (when conditions make the course more difficult), into the score differential calculation, depending on the conditions of the course for the given day.
What is a golf handicap?
A golf handicap is intended as a measure of a golfer's potential playing ability. The higher the handicap of a golfer, the poorer the golfer's ability relative to that of a person with a lower handicap.
