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.
While the course rating indicates the difficulty of a course for a scratch golfer, the slope rating, by contrast, indicates how difficult the course should be for a bogey golfer (or someone who averages +18 for 18 holes). Also unlike course rating, slope values can range from 55 to 155 with 113 being the average.
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.
Course Ratings represent the difficulty of a golf course for the scratch player under normal conditions. Slope Ratings represent the difference in difficulty for all other players, compared to the scratch player. Course Ratings are carried out by qualified teams, and assume normal course and weather conditions.
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.
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.
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.
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 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.
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.
Slope ratings are calculated as a multiple of the difference between the expected good score for a bogey golfer (handicap in the range 20 to 24), called the bogey rating, and the expected good score for a scratch golfer (zero handicap), called the USGA Course Rating.
KIAWAH 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.
Bogey Golfer-A player with a USGA Handicap Index of 17.5 to 22.4 strokes for men and 21.5 to 26.4 for women. Under normal situations the male bogey golfer can hit his tee shot 200 yards and can reach a 370-yard hole in two shots.

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. When we looked at the course rating, you saw that the number kind of coincided with what par is on the course. The bogey rating or slope rating is much different.
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.
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 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.
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.
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;
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.
While the course and slope ratings of a golf course are unlikely to change dramatically, they are usually re-evaluated every 4-5 years.
It turns out that that statistically, no matter how easy or hard a course is, scratch golfers will almost always shoot in the high 60’s to low 70’s. While this might not seem like a big deal, having a very narrow spread of scores even on courses that are much easier or harder than average ones creates a rating that underestimates changes in course difficulties for the rest of the golfing population. However, they also realized that this phenomenon was the exact opposite for mid-high handicap golfers. While one course might only play slightly harder in the eyes of a scratch golfer, less proficient golfers might find their scores to be significantly higher on this new, harder course.
If you’re interested in calculating your handicap for a particular course, multiply your handicap by the course rating divided by 113. This will adjust your handicap to the difficulty of the course.
This scorecard shows the course rating (first number) and slope rating (second number) for each set of tees at a course.
As you may have figured out already, golf is a difficult game and contains a very wide range of golfers, each with very different levels of skill. In the mid 80’s the USGA started to catch on to this big divide between scratch or professional golfers and mid to high handicap golfers.
These two factors of change, both physical change and increased experience, frequently work against each other and often times nearly cancel out most changes in ratings, however, the possibility is always there. Although many of us spend very little time considering the ratings of courses we play, looking at courses through a different lens, such as how a scratch versus bogey golfer might play a hole, is actually a great way to improve your course management skills.
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.".
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.
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:
Therefore, the course rating provides scratch golfers information about the course difficulty, while the slope rating delivers the same information to bogey golfers. In other words, the USGA slope rating indicates the additional playing difficulty of the course for average golfers compared to scratch players. The dominant factor that defines the course difficulty is the golf course rating, not the slope rating.
The standard procedure to calculate the slope rating is to multiply the difference between the bogey rating and the USGA score rating. The score you get when the expected good score for a Scratch golfer (a zero handicapper) is multiplied by the expected good score for a bogey golfer (a Mid handicap golfer with a range from 18 to 30).
When rating the course, the team evaluates the landing area for a bogey golfer the first 200 yards off the tee. They measure the width of the fairway, consider any existing bunkers, and estimate the distance from the fairway center to the nearest boundary/hazard line or trees. The same measurement is applied for scratch golfers, adding 50 yards to the landing area off the tee. The process continues until the team reaches the green. There, the rating team measures the depth and the width of the Putting green, the bunkers and the water hazards, and the distance to the boundary line.
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:
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.
A golf course slope is a USGA designated rating number that indicates the difficulty of a specific course for bogey golfers. This number is used to calculate a player’s handicap index. The value is between 55 and 155, and the average standard slope number ranges from 113 to 120. The higher the slope number, the more difficult the golf course is for average golfers.
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 ...
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.
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.
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.
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, ...
Handicappers use the term ‘de-sloped’ for this and it is achieved using that number, the actual gross score – which has been adjusted for net double bogey – and the Slope Rating of the course on which that score was recorded.
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.
