How To Build A Ramp For A Shed On A Slope?

How do you calculate the angle of a shed ramp?

Ideally, you want 2 inches of rise for every 12 inches of run. This will give you a slope of 11 to 12 degrees. For instance, if you have a shed door that is 4 inches above ground level, you need a ramp that is 2 feet long.

What is the maximum allowable slope for a ramp?

The maximum recommended slope of ramps is 1:20. Steeper slopes may be allowed in special cases depending on the length to be covered (fig. 4). Ramps should be provided with landings for resting, maneuvering and avoiding excessive speed.

How do you install a shed on a slope?

  1. Determine the degree of unevenness on the shed site.
  2. Solve modest slope problems by excavating a high side and building up the soil on a low side so foundation blocks are set with tops level.
  3. Use pier and beam construction for steeper slopes.
  4. Move the shed location if the uneven site is an area of heavy water runoff.

How do you calculate the length of a ramp?

Determining Ramp Length:



Measure total rise (how many inches from lower level to upper level) and divide by the slope.

How do you cut a stringer for a ramp?

Use a circular saw to cut triangular stringers based on your rise and slope measurements. The nominal size of the boards you select depends on the ramp rise. For example, 2- x 6-inch lumber could be used as stringers if the rise is less than 5 1/2-inches; a rise greater than that would require a 2- x 8-inch board.
