Slope: 10.00% (ascending, 5.71 deg)

  • A 10.00% grade equals an angle of 5.71 degrees from horizontal.
  • Expressed as a ratio, this is 1:10.0: one m of rise for every 10.0 m of horizontal run.
  • This is a moderate slope. Residential driveways are typically limited to 10-12% by local codes, and mountain bike trails in this range are rated blue (intermediate).

Next stepCheck your local road, building, or accessibility code for the maximum permitted grade in your application.
