Slope Rating Calculator

Calculate a golf course slope rating based on scratch and bogey ratings

๐Ÿ‡ฉ๐Ÿ‡ฐ All calculations are based on Danish rules, rates, and currency (DKK). This calculator is translated for convenience but applies exclusively to Denmark.

Calculate slope rating

Slope rating measures a golf course's relative difficulty for bogey golfers compared to scratch golfers. It is calculated from the difference between bogey rating and scratch rating multiplied by 5.381.

What is slope rating?

Slope rating ranges from 55 to 155, with 113 as the standard. A higher slope means the course is relatively harder for weaker players. Slope is used in calculating course handicap.

Scratch vs. bogey rating

Scratch rating is the expected score for a scratch golfer (handicap 0). Bogey rating is the expected score for a bogey golfer (handicap ~20-24 for men). The difference reflects how much the course penalises weaker players.

Difficulty levels

Courses with slope below 90 are considered easy. 90-110 is moderate, 110-130 is difficult, and above 130 is very difficult.

Frequently Asked Questions

What is a typical slope rating?

Most golf courses have a slope between 100 and 130. Standard is 113. Par 3 courses and easy courses typically have slope below 100. Championship courses can have slope above 140.

Who determines slope rating?

Slope rating is determined by the national golf union through an official course rating process. Trained course raters evaluate the course based on obstacles, length, terrain and other factors.

How is slope rating used in practice?

Slope rating is used to calculate your course handicap: Course Handicap = Handicap Index ร— Slope / 113 + (Course Rating โˆ’ Par). This ensures all players get a fair number of extra strokes regardless of course difficulty.
