Ramp Length Calculator
Calculate horizontal ramp run and sloping length from rise and target gradient.
Horizontal run
9 m
Sloping length
9.03 m
Slope
8.33%
How this works
Horizontal run = rise × gradient denominator; slope length follows Pythagoras.
Worked example
A 0.75 m rise at 1:12 needs 9 m horizontal run before landings.
FAQ
What is the Ramp Length Calculator used for?
Calculate horizontal ramp run and sloping length from rise and target gradient. It is intended for quick planning, checking, and everyday decisions.
Can I use the result for a final contract or design?
Use it as a planning estimate. Landings, handrails, edge protection, width, headroom, and local accessibility rules also govern design.
How can I improve the accuracy?
Use measured quantities, current supplier or lender rates, the correct units, and compare the result with drawings, invoices, or professional advice where the decision is safety-critical.
