Slope vs Course Rating in Golf

Terms in golf are used for many different purposes. The most popular concepts are Slope vs Course Rating.

They play a crucial role in determining the surrounding environment and tactics to make the most of their strengths.

To learn more about these two concepts, please refer to the article below.


What Do These Terms Mean In Golf? 

The United States Golf Association has given three types of indicators,

Course, Bogey, and Slope, to determine the difficulty of a golf course system.

Those terms are some of the essential concepts that every golfer should know, including Course Rating and Slope Rating.

The USGA recommends system member golf courses with their course difficulty updated.

A new golf course management should be updated every three years for the first ten years, then every ten years. 

When assessing the difficulty of a golf course, factors like: is it easy or difficult to put the ball on the fairway, the probability of hitting the green area from the fairway, the ability to fall and save the ball from the rough area, etc., are considered hindering factors.

So, They will be evaluated from 0 to 10 and then aggregated into “The level of obstacles caused to the player”.

+ Courses vs Slope Ratings: Things To Know For Handicap Golfer

Courses Rating is the most common rules metric to describe the difficulty a member of golf course’s that every professional or amateur golfer must know.

Golfers will use these numbers to estimate the number of strokes they need to complete 18 holes in standard weather and surface conditions. 

Slope ratings are related to two factors: bogey and course rating.

The Bogey rating is an index showing the difficulty of a bogey golfer, assuming that the pitch and weather are standard.

Like the Courses Rating, the Bogey rating indicates the number of strokes a bogey player needs to hit to complete the round through decimal numbers.

This stat depends on the length of the shot, the effectiveness of the shots, and the obstacles.

Slope rating is calculated from the difference between Bogey rating and Course rating on each type of tee.

A golf course with standard difficulty will have a Slope rating of 113, which is also a constant in the calculation of HDC for players at different difficulty levels.

These two indicators also target two different types of athletes.

While the course rating is used to measure the difficulty of the course for professional players, the Slope rating refers to the difficulty level of the general player level.

+How to Know About Slope Rating And Course Rating With Golfers?

The rating team staff usually has four or more golfers consisting of 2 standard golfers (one male, one female) and two bogey golfers (one male, one female).

They will play all tees and score points, to sum up, the calculation using the formula:

  • Course Rate = Standard player’s yardage rate + The Level of obstacles inflicted on the standard player.
  • Bogey Rate = Yardage rate of bogey player + Level of obstacle caused to the standard player.

Slope rating calculation is somewhat more complicated when distinguishing between men and women clearly.

  • Men’s Slope rate = 5,381 x (Bogey rate – Course rate)
  • Women’s Slope rate = 4.24 x (Bogey rate – Course rate)

Both the Course rating and slope rating are calculated using averaged division calculations performed on a computer system.

Athletes with different fitness will compete under other weather conditions so that the computer can collect the most accurate data. 

After all, data is available, the USGA’s world handicap system will automatically calculate and store the correct index.

New course rating, including slope, is coming - what you must know!

All golfers know these metrics are quite crucial for calculating HDC.

A golf course with a Course Rating of 73.7 means that a “standard player” will take an average of 73.7 strokes to complete the round under moderate weather and fitness conditions. 

Most golf courses rating is from 60 to 75.

Amature male scratch golfers must have an HDC of 0, averaging 250 yards, and be able to hit two green strokes on the road at 470 yards. 

If they are female, they must have a tee shot 210 yards and put the ball on the green with two strokes at a distance of 400 yards.

This is an important criterion to help golfers change plans and set training goals that are best suited to their fitness.


Slope vs Course ratings are two indicators that show the difficulty level of a golf courses for amateur and professional golfers.

however, the Slope rating is not closely related to the player’s number of clubs but like Course.

These are two essential metrics that all golfers should know.
