Full Answer
While course ratings are a measure of the difficulty of a course, slope ratings are a measure of how much more difficult a course is for a high handicap golfer versus a lower one. For example, if you have two courses that each have a course rating of 72, they should be the same difficulty for a scratch golfer.
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.
The “standard” or base slope rating is 113, meaning a course that is rated at 113 will play to a standard difficulty level. From there, the ratings can go up and down all the way from 55 up to 155. 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.
While course ratings are a measure of the difficulty of a course, slope ratings are a measure of how much more difficult a course is for a high handicap golfer versus a lower one. For example, if you have two courses that each have a course rating of 72, they should be the same difficulty for a scratch golfer.
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.
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.
Most scorecards will have the slope rating printed on them. There is a separate slope rating for each of the different tee boxes on the course. The average slope rating of a golf course is typically 113. If the slope of a golf course is less than 113, the course is easier than the average golf course.
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.
155KIAWAH ISLAND / S.C. / 7,356 YARDS / PAR 72 (Eight of our top 50 were created by the man they call the "Marquis de Sod.") The Ocean has the highest combination of Slope Rating (155) and Course Rating (79.6) in America, according to the U.S. Golf Association.
The higher the Slope Rating, the harder the course is for the bogey golfer, relative to the difficulty of the course for the scratch golfer. Slope Ratings can range anywhere between 55 and 155, with the average slope rating in the United States being approximately 120.

The handicap index is an average of golf round scores and has its own calculation. This formula requires you to sum your differentials and divide these by the number of differentials used, and then multiply the result by 0.96.
A Bogey Golfer is one with a Course Handicap of 20 (24). He (she) can hit tee shots an average of 200 (150) yards and can reach a 370 (280)-yard hole in two shots.
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.
Slope Rating is calculated by subtracting the Course Rating from the Bogey Rating and multiplying it by a constant.
The Slope Rating for a golf course tells you how difficult the golf course is for a bogey player (about a 20 handicap for a male golfer) compared to a scratch player. The higher the Slope Rating, the harder the course is for the bogey golfer, relative to the difficulty of the course for the scratch golfer.
Augusta National Golf Course The 18-hole "Augusta National" course at the Augusta National Golf Club facility in Augusta, Georgia features 7,270 yards of golf from the longest tees for a par of 72. The course rating is 74.0 and it has a slope rating of 135 on Bermuda grass.
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
A slope edition rangefinder gives you the distance to the flagstick, and the degree of elevation to the target. The change in elevation (Slope) will give you a 'Play like' yardage, so you can calculate the right club for the shot based on the yardage and slope.
The average slope rating is 120, according to Dean Knuth, also known as “the pope of slope,” the man who invented the system in 1982. In conclusion, course ratings and slope ratings are useful and objective measures of golf course difficulty.
Authorized by golf associations and using USGA standards, course rating teams closely study a golf course and collect a lot of data, including on each hole.
A female scratch golfer can hit 210-yard tee shots on average and reach a 400-yard hole, at sea level, in two shots. Meanwhile, the USGA says bogey golfers have a course handicap of 20 for men and 24 for women on golf courses of standard difficulty. Average yards off the tee are 200 for men and 150 for women.
This begs another definition. Namely, the bogey rating. In a nutshell, it’s the playing difficulty of a golf course for a bogey golfer.
And what is a scratch golfer? According to the USGA, a scratch golfer is a man or woman who can play to a course handicap of zero on all rated golf courses. In others words, he or she can shoot a score that nearly matches the course rating from his or her designated tees.
One thing that makes golf different than other sports is the “playing field.”. Whether long or short, hilly or flat, no two golf courses are alike. And while they’re all challenging in their own way, some golf courses are harder than others. In fact, some courses are like childhood bullies who will steal your lunch money ...
Plus, courses change, which is why they must be re-rated at least every 10 years.
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. To put it another way: USGA Course Rating ...
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does).
The minimum slope rating is 55 and the maximum is 155 (slope does not relate specifically to strokes played as course rating does). The higher the slope, the more difficult the course is. 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. Some do, but the real-world average is higher than 113. (However, a slope of 113 is still used in certain calculations within the handicap system.)
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.
Course rating is very easy to understand because it is expressed in strokes. 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;
The slope values can range anywhere from 55 to 155. The average golf course is 113. This may seem like an odd number for a bogey golfer to have to remember and base their golf round off of. The United States Golf Association came up with these systems, and they work pretty well, but there is undoubtedly a learning curve involved.
A golf course rating is a number that tells you what a scratch golfer should be shooting at that golf course. Scratch golfers are known for their ability to shoot par on a golf course. However, not all golf courses are made to be the same difficult.
If a scratch golfer plays this course and shoots a 74, the player’s handicap differential would still be zero. Therefore the golfer’s handicap index is not going to be adjusted or changed all that much because they were playing a more challenging golf course.
A higher golf course rating means that the course raters have decided that it is much harder for a scratch golfer to shoot par at the golf course. Chances are the course rating is closer to 74 or even 75, and therefore that is what a typical scratch player would shoot.
The handicap system allows bogey golfers to have a fair match against scratch golfers, which makes golf such a special and vital sport.
The concept of the USGA course rating system is to help ensure that you can play any golf course and have a good idea of what you are getting yourself involved in.
The handicap index is created by calculating an average of 20 score differentials of a player. The score differential is the difference between your adjusted gross score and the course rating. Therefore if you are a golfer that shot 90 on a course with a 72.5 rating, your score differential would be 17.5.
You calculate slope rating by finding the bogey rating, which is like the course rating, but measured for a bogey golfer. Then subtract the course rating from that figure. Then multiply that figure by 5.381 for men and 4.24 for women. Then round up to the nearest whole number.
A golf course rating tells you what a scratch golfer would be expected to shoot from the tees they're playing on a particular course under normal conditions. The rating is different for men and women.
The golf course slope is a measure of a course's difficulty, but it is not considered the better of the two measurements. Golf course slope is actually derived from the golf course rating. Slope is a measure of a golf course's difficulty in a relative comparison of a scratch golfer to a bogey golfer (someone who shoots around 90 for 18 holes).
A male scratch golfer, for rating purposes, can hit tee shots an average of 250 yards and can reach a 470-yard hole in two shots.". A scratch woman can "can hit tee shots an average of 210 yards and can reach a 400-yard hole in two shots at sea level.".
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.
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.
Course and slope rating can impact final scores in scramble tournament play.
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.
Course and slope rating are both used in determining a handicap differential. The course rating is an estimated average score for a scratch golfer. It’s usually a number between 67 and 77. Slope Rating is also an estimated average, but it’s for what an average or bogey golfer would shoot on that course. Let’s take a look at slope rating in action:
Slope Rating [Infographic] A golf course’s slope rating is listed on their score card, along with the par for that course and the course rating. These numbers are intended to help golfers determine the difficulty of the course. Course and slope rating are both used in determining a handicap differential.
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.
Slope Ratings are described by the USGA as indicating the “measurement of the relative playing difficulty of a course for players who are not scratch golfers, compared to scratch golfers”. Every course in the UK is being assessed using a course rating system, which focuses on scratch and bogey golfers.
That probably doesn’t sound like much to you, but using that neutral rating means you can compare your WHS handicap index, and your potential, against any golfer in the world – regardless of whether they play at Pebble Beach or Powfoot. When WHS comes into effect, every score returned by every player, from every course, ...
A bogey golfer is classed as about a 20 handicapper for a man , and 24 for a woman. The Slope Rating is then created by taking the difference between those two ratings and multiplying it by a predetermined factor. Every set of tees on every course will have a Slope Rating and those numbers will vary between 55 and 155.
England Golf, who are charged with bringing in the WHS in this country, say: “The most significant factors involved in determining Slope Rating are length, trees, rough and water hazards.
The course rating is produced by considering the number of strokes a scratch player would be expected to complete a round in under normal playing conditions.
For most of us, Slope will be a huge factor when we play a round under the new World Handicap System. Steve Carroll explains how it works
