How to use this tool

  1. Enter vertical rise, horizontal run.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Grade = rise/run × 100%. Angle = arctan(rise/run).

A WORKED EXAMPLE

Using vertical rise = 0.3 m, horizontal run = 6 m, the result is 5 %. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Does not determine accessibility or code compliance. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

Which inputs does this calculation need?

Find grade percentage and slope angle from rise and run. Enter vertical rise in m, horizontal run in m. The filled example is editable and is not a saved personal record.

How should I interpret the result?

Does not determine accessibility or code compliance. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
