How it works
Express a ground slope as a percentage and angle.
THE CALCULATIONgrade = rise/run × 100; angle = arctan(rise/run)
Using this calculator
Enter vertical change (m), horizontal distance (m). grade = rise/run × 100; angle = arctan(rise/run).
What to keep in mind
A quantity estimate using your measurements, not a structural design, building-code check or purchasing specification. Allow for real shapes, cutting and the product instructions.
Frequently asked questions
Are my entries saved?
No. Calculator inputs remain in the current page and are cleared when you reload or leave. The tools do not upload your entries.
Why are results rounded?
The display is rounded for readability. Calculations use unrounded intermediate values. An estimate should not be interpreted as an exact measurement.
