By subtracting the bogey rating from the course rating, then multiplying by either 5.381 for men, or 4.24 for women, you arrive at the course’s Slope Rate. Easy! The slope rating doesn't necessarily tell you how hard or easy a particular course is. But it does tell you how much more difficult it is for a bogey golfer compared to a scratch golfer.
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 a slope rating on a golf course?
A golf course's slope rating is a mathematical representation of the course's difficulty. USGA par rating is taken into account as well as the projected score of a higher handicap player when calculating the course's Slope rating. In order to calculate the men's slope rating, multiply the difference between the two numbers by 5.381.
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 golf slope and why is it important?
Here is a simple explanation of what it is and why golf slope is important for your game. 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.
What is a good slope for a golf 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 is the difference between course rating and slope?
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. Course rating tells scratch golfers how difficult the golf course will be; slope rating tells bogey golfers how difficult it will be.
How do you get a slope rating?
Multiply the difference between course rating and bogey rating according to gender. For male golfers, multiply the difference by 5.381; for women, multiply it by 4.24 and round to the nearest whole number. This is the slope rating.
How do you calculate the slope of a 9 hole line?
The actual calculation is as follows: 9-Hole Score Differential = (Adjusted Gross Score for 9 holes x 113/Slope Rating + second nine par + 0.5 x Course Handicap) – Course Rating.
What is the slope of Augusta National?

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.
What is golf slope formula?
Slope Rating is calculated by subtracting the Course Rating from the Bogey Rating and multiplying it by a constant.
How does the golf slope system work?
Every set of tees on every course will have a Slope Rating and those numbers will vary between 55 and 155. The higher the Slope Rating, the greater the difference expected between the scores of those scratch and bogey golfers. A higher rating doesn't necessarily mean that the course is more difficult than another.
How does golf slope work?
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!
Is 44 a good golf score for 9 holes?
A golf score of 45 is considered to be good for a game of 9 holes. This is a realistic score for most golfers to aim for. Any score below 40 is considered excellent.
What is a good handicap for 9 holes?
On the 9-hole course, it should be 18.2 for men and 20.2 for women.
Is golf handicap based on 9 or 18 holes?
Each golf course that has an 18-hole Course Rating™ and Slope Rating® also has nine-hole Ratings. These can be found in the Course Rating and Slope Database™. You have a Handicap Index® which is designed to convert to a Course Handicap™ for 18-hole play.
What Course Rating means?
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.
How does Course Rating and slope affect handicap?
Slope Ratings range from 55 to 155, with the average being 113. 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.
Does higher slope rating mean harder course?
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 you calculate handicap with 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.
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.
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:
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.
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.
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.
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.
What does USGA course rating mean?
To put it another way: USGA Course Rating tells the best golfers how hard a golf course actually plays; USGA Slope Rating indicates how much harder the course plays for "regular" (meaning not among the best) golfers.
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.
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.
Myth No. 1 – Slope is the primary indicator of difficulty or, to put it another way, the higher the Slope, the more difficult the course
Wrong! As the above example confirms, it is the Course Rating and not the Slope, which is the more dominant factor in defining course difficulty.
Myth No. 2 – Slope ratings can he compared between courses
Wrong! I wish I had a dollar for every letter, E-mail or phone call I have received criticizing existing ratings on the basis of the Slope only. In short there is nothing more dangerous than trying to draw any sort of meaningful conclusions by comparing Slope Ratings from one course to another.
So what is 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.
