What is a slope rating in golf courses?
The slope rating is a number that indicates how challenging a golf course is for a bogey golfer. Of course, nothing in golf is quite that simple, so the slope rating is not as easy to figure out as the course rating.
How do you calculate slope on a golf course?
Slope (men) = 5.381 x (bogey rating – USGA course rating) Slope (women) = 4.24 x (bogey rating – USGA course rating) So, once the golf course is rated, the bogey rating and the scratch rating are determined for each set of tees, leading to determining the slope number. What is USGA Golf Course Rating and Who Rates It?
What is the average slope of an 18 hole golf course?
The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.
What is the difference between a handicap and a course slope?
Handicaps, and course rating and course slope go hand-in-hand. Handicap is a number assigned to a golfer, indicating the number of strokes over par they are on an average round of golf. For instance, a golfer with an 18 handicap would typically shoot 18-over par during a round of 18 holes.
What does the slope of a course mean?
The Course Slope predicts the difficulty of a course for a “bogey” golfer, someone who shoots 18 over par or 90. Course Slope is a number between 55 and 155, with 113 being the average. The higher the number the more difficult the course. As with course rating each set of tees will have a slope rating.
How do you interpret course rating and slope?
Slope merely tells you how “proportionately” more difficult that particular set of tees plays for the higher handicapped golfers as opposed to lower handicapped golfers. The more difficult the tees play proportionately for the higher handicappers, the greater the Slope rating that will be issued. That's it!
What does the slope represent?
We call m the slope or gradient of the line. It represents the change in y-value per unit change in x-value. For example, consider the line given by the equation y = 2x + 1. Here are some points on the line.
Does higher slope mean harder course?
The higher the slope number, the harder the course is for the bogey golfer relative to the difficulty of the course for the scratch golfer. Slope numbers can range anywhere between 55 and 155 with the average slope in the United States being 120.
What does a slope rating of 130 mean?
From Tom's tees, a slope of 130 gives him a 12 Course Handicap.
How does course rating and slope affect handicap?
When you play a course with a Slope Rating higher than 113, your Course Handicap will be higher than your USGA Handicap Index. When you play a course with a Slope Rating lower than 113, your Course Handicap will be lower than your Handicap Index.

What is a good golf course rating?
A par-72 course that is easy might have a course rating of 68.9; one that is difficult might have a course rating of 74.5. That means that a scratch golfer should be expected to average 68.9 strokes in his better rounds at the easier course; and 74.5 at the more difficult one.
What is a difficult slope rating in golf?
What is a hard slope rating? If we know that the average slope rating of a golf course is 113, we can deduce that any golf course with a slope rating higher than 113 is more difficult than the average course. Don't be intimidated if you see a slope rating that is above 113.
How do they rank golf courses?
The Course Rating is calculated from the effective playing length and obstacle factors for 9 or 18 designated holes. The Course Rating is expressed in strokes to one decimal point and represents the expected score for a scratch player. The Bogey Rating represents the expected score for a bogey player.
What is the slope of a golf course?
The Course Slope predicts the difficulty of a course for a “bogey” golfer, someone who shoots 18 over par or 90. Course Slope is a number between 55 and 155, with 113 being the average. The higher the number the more difficult the course. As with course rating each set of tees will have a slope rating. For example, the blue tees might be 123, the white tees 119, and the red tees 114.
What is the slope of the second course in golf?
The second course is also rated at 72 but has a slope of 135. The increased Course Slope could be a result of the length of the course. A longer course can wreak havoc on a bogey golfer. He is hitting long irons or woods into most greens, which will usually result in a missed green.
What is the score of a bogey golfer on a second course?
So while the par golfer will still shoot 72 on the second course, the bogey golfer will have a score above 90.
What is a course rating?
Course Rating. Course Rating indicates the difficulty of a course for a “par” or scratch golfer. For example, if a course has a par of 72, the Course Rating might be 71.4. This is the score the scratch golfer is expected to shoot on the course. The number goes up with the difficulty of the course.
Do you have to record your score when you turn in a score?
Every time you turn in a score you are required to record the Course Rating and Slope for the course and set of tees you played. Many golfers are familiar with the terms Course Rating and Slope, but don’t really know what they mean.
Is 72 a long course?
The course rated at 72 with a slope of 113 is probably not a long course. Or maybe it has wide fairways and with few hazards. So the par golfer still shoots par on this course and the bogey golfer shoots 90. The second course is also rated at 72 but has a slope of 135.
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 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 the average slope rating for golf courses?
The United States Golf Association established the average slope rating to 113, but it has later increased to about 120 as there aren’t many 18-hole golf courses with slope ratings set that low. As has been observed, most golf courses worldwide have average slope ratings of about 120.
How many strokes does a par 72 golf course have?
It is expressed in strokes, so an easy par-72 golf course could have a 68.9 course rating, while the more difficult one is likely to have a rating of 74.5. In other words, an average golfer should expect to play 68.9 strokes when the course playing difficulty is rated ‘easy,’ while on a challenging course, the same golfer is expected ...
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.
What are the slope and course rating in golf?
While frequently unused by new or casual golfers, slope and course rating are two of golf’s most important, and most commonly confused numbers. These two numbers might be a seemingly random arrangement of numbers on your scorecard, but in reality , they are two of the great equalizers in the game of golf.
How often are golf course slope ratings re-evaluated?
While the course and slope ratings of a golf course are unlikely to change dramatically, they are usually re-evaluated every 4-5 years.
What is the slope rating of a bogey golfer on a course?
However, if bogey-golfers on course A averages a score of 90 while bogey-golfers on course B average a score of 95 the slope rating for course B would be higher than for course A; indicating a higher level of difficulty for higher handicap players.
What is a course rating?
The simple answer is, a course rating is a number that indicates what a scratch golfer (a golfer that averages par for a round) should shoot on this particular course. So, while the par for a particular course might be 72, a course rating of 70.1 would indicate that a scratch golfer should be almost two under par on average.
What is the slope of a golf course?
Course slope is a figure that indicates the difficulty of a course in relation to a golfer who averages a bogey on every hole, and therefore, averages 18-over par on any given round.
What is a course rating?
Course rating is a figure that indicates the difficulty of a golf course to a golfer who averages even par on a round of 18. For instance, a course rating of 72 would portend that a "scratch golfer" would shoot 72 on that particular course.
What is a golf handicap?
Handicap is a number assigned to a golfer, indicating the number of strokes over par they are on an average round of golf. For instance, a golfer with an 18 handicap would typically shoot 18-over par during a round of 18 holes. On a course with a course rating of 72, this golfer would be expected to shoot 90. Meanwhile, a golfer with a 20 handicap would be expected to shoot 92 on this same course.
What is slope rating?

What is USGA course rating?
USGA Course Rating is an evaluation of the difficulty of a golf course for scratch golfers. (More specifically, the number is an estimate of the average scores of the best 50-percent of rounds played by scratch golfers at the course being rated.) Course rating is very easy to understand because it is expressed in strokes.
What is the role of slope in golf?
The most important role of a slope is leveling the playing field for players of different skill levels. For example, let's say Player A and Player B average 85 strokes each for 18 holes. But Player A's average is established on a very difficult course (say, a slope rating of 150), while Player B's average is established on a much easier course (say, a slope rating of 105). If handicaps were simply estimates of golfers' average scores, then these two players would have the same handicap index. But Player A is clearly the better golfer, and in a match between the two Player B would clearly need some strokes.
What is slope rating in golf?
Slope rating (a term trademarked by the United States Golf Association) is a measurement of the difficulty of a golf course for bogey golfers relative to the course rating.
Why is the handicap index lower for A and B?
Because he plays on a course with a higher slope rating, Player A's handicap index will be lower than Player B's (when it is calculated using the slope ratings), despite the fact that they both average scores of 85. So when A and B get together to play, B will get those extra strokes he needs.
What is the minimum slope rating for 18 holes?
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does). When the slope rating system was first put into effect, the USGA set the slope for an "average" golf course at 113; however, not many 18-hole golf courses have slope ratings that low.
