Slope rating measures how much harder a course is for a bogey golfer (18 handicap) compared to a scratch golfer. The standard slope is 113; higher slope (up to 155) means the course is proportionally more difficult for higher handicappers. Slope is used to convert a handicap index to a course handicap: Course Handicap = Handicap Index × (Slope ÷ 113). A high slope course has many penalty areas, length and narrow fairways that punish inconsistency disproportionately.
- Standard slope = 113
- Higher slope = disproportionately harder for higher handicappers
- Used to calculate course handicap
- Range: 55 (easiest) to 155 (hardest)

Slope rating measures how much harder a golf course plays for a bogey golfer relative to a scratch golfer, on a scale from 55 to 155 (113 is the 'standard' average difficulty) — this is the key input that converts a golfer's portable Handicap Index into a course-specific Course Handicap, ensuring players of different skill levels compete fairly regardless of which course's difficulty they're facing.
FAQ
What does a slope rating number mean?
It measures relative difficulty for a bogey golfer compared to a scratch golfer, ranging from 55 to 155, with 113 representing standard average difficulty — higher numbers indicate a course that's disproportionately harder for higher-handicap players.
How is slope rating used in calculating a golfer's handicap?
It's the key factor that converts a golfer's Handicap Index (a portable measure of ability) into a Course Handicap specific to that course and tee, under the World Handicap System.
