A quick check against the rule’s main numbers, not an inspection. Local rules can add more.
How to use it
- Pick the rule
The rule for your country, and for stairs whether it’s a home or a public building.
- Type the sizes
The height to climb and the ramp’s length, or floor to floor and the tread depth.
- Read the check
Each number shows whether it’s within the rule, with the reason when it isn’t.
Tips
- Make it longer
A ramp that fails gets gentler with more length: the shortest allowed length is shown.
- Even risers
Every riser in a flight should be the same height. The calculator splits the height evenly.
- Measure what’s built
Lay your phone on a built ramp or stair with the level to read its real slope.
