Ramp Calculator

Calculate ramp run, slope percentage and angle from rise and a chosen slope ratio.

Project inputs

Enter your project values, then press Calculate.

How this calculator works

Calculate ramp run, slope percentage and angle from rise and a chosen slope ratio.

run = rise × N; slope% = 100 ÷ N

How to use the Ramp Calculator

1. Enter project inputs

  • Vertical rise (m)
  • Slope ratio 1:N

2. Review the results

  • Required horizontal run
  • Ramp length
  • Slope
  • Angle

3. Check the calculation

The calculator uses the following core relationship:

run = rise × N; slope% = 100 ÷ N

Estimating note: Actual material quantities can vary with site conditions, detailing, product dimensions, installation method, and waste.

Ramp Calculator FAQ

What does the Ramp Calculator calculate?
