Every golf course is unique, with differences in terrain, grass type, scenery, and weather.
One of the lesser-known measures of a course’s difficulty is its slope rating.
A slope rating evaluates the playing difficulty of a course for both scratch golfers and bogey golfers under normal playing conditions. A higher slope rating indicates a more challenging course, while a lower rating suggests an easier course.
Slope ratings are particularly useful for golfers with handicaps. Course length and hazards affect higher-handicap players more significantly than low-handicap players. By combining slope ratings with the handicap system, golfers can better understand how a course will challenge them compared to their skill level.
Slope ratings are calculated by subtracting the course rating from the bogey rating and then multiplying the result:
Each tee box on a course receives its own slope rating, as difficulty varies depending on whether you play from the back or front tees.
Key terms to know:
To calculate these ratings, courses consider their effective playing length and 10 obstacle factors for each hole, including:
While slope and course ratings are often listed on scorecards, understanding them is crucial. They help golfers assess their ability relative to their playing partners and choose the most suitable tee boxes.

Woodhall Spa Golf Club in Lincolnshire, England, has the highest slope rating in the UK at 152, making it one of the toughest courses in the country.
The hardest slope rating in golf is 155, representing the maximum difficulty a course can have.
A higher slope rating means the course is more challenging and will test golfers’ skills more than average.
Any slope rating above the standard 113 is considered difficult, with 155 being the highest and most challenging.
A slope rating between 55 and 113 is generally considered easy to average, with 55 being the easiest and 113 representing a standard course difficulty.
