[edit] Slope Steepness

There are two ways of measuring slope steepness. The first is a measurement using degrees, which measures the angle of the slope in degrees from the horizontal. The second is a percentage.

There are two ways of measuring slope steepness. The first is a measurement using degrees, which measures the angle of the slope in degrees from the horizontal. The second is a percentage.

This is calculated using the formula 100*rise/run. Rise is the vertical change and run is the horizontal distance. A 100% slope is angled at 45 degrees.

  • 10% is equivalent to 5.71º
  • 20% is equivalent to 11.31º
  • 30% is equivalent to 16.7º
  • 40% is equivalent to 21.8º
  • 50% is equivalent to 25.67º
  • 75% is equivalent to 36.8º
  • 100% is equivalent to 45º

A beginner slope is typically between 6% and 25%. Intermediate hills range from 25% to 40%, and expert is 40% plus.
