Ramp Calculator – Smart & Accurate Slope Tool

Ramp Slope Calculator

Compute angle, grade %, run, and ramp length from your rise or ratio. All fields sync.

Ramp Specifications

Application

Rise-to-run ratio

Set when “custom” is selected. Ratio is rise : run.

Ramp type

Straight 90° turn (dog-leg) 180° turn (switchback)

Type is noted for design context; calculations use pure geometry.

Rise

Ramp Details

Slope angle

Elevation grade

Run

Ramp length (hypotenuse)

Step-by-step derivation

References

Right-triangle trigonometry: ( theta=arctan(text{rise}/text{run}), L=sqrt{text{rise}^2+text{run}^2} ).
Accessibility guidance commonly cites slopes such as 1:12, 1:16, and 1:20; select the ratio that applies to your design or local code.
