How long doesyour ramp need to be?
Enter the height of your step and the calculator draws your ramp to scale. It shows the type of ramp you need, how long it will be, and where it needs a flat landing.

A step ramp
For a single step up to 190 mm, no longer than 1.9 metres. A rubber ramp or a small built ramp suits. If you have the room, a 1:14 ramp is easier to push up.
See rubber ramps| Type | Gradient | Min run | Status |
|---|---|---|---|
| General access ramp | 1:14 | 2.52 m | Allowed for this rise |
| Step ramp | 1:10 | 1.80 m | Allowed for this rise |
| Threshold ramp | 1:8 | 1.44 m | Not suitable |
This is a guide based on the Australian Standard for access (AS 1428.1), not a design. A safe ramp also depends on its width, rails, edges, surface, and the door at the top. That is why we measure and design every ramp on site.
Understanding the numbers
What each gradientmeans for you.
A long, gentle ramp (1:14)
For anything higher than one step. The ramp rises 1 cm for every 14 cm of length. It needs a flat landing at least every 9 metres, and at a home it usually turns at a landing to fit the space.
A step ramp (1:10)
For a single step up to 190 mm. It rises 1 cm for every 10 cm, and can be no longer than 1.9 metres. Good where space is tight, though a gentler ramp is easier to push a wheelchair up.
A threshold ramp (1:8)
Only for a door sill up to 35 mm, and no longer than 280 mm. It is the steepest slope the standard allows, and only for this.
Landings and turns
A flat landing is at least 1.2 metres long. Turning a corner needs a landing at least 1.5 by 1.5 metres, and turning right around needs one at least 2.07 by 1.54 metres. There must be at least 1 metre of clear space between the handrails.

Rubber ramps
For a doorway lip or a single step. Nothing is fixed down, and it is often in place the same day.
All ramps
Every ramp we fit, from small aluminium ramps to timber and composite, and how we choose.
Wheelchair access ramps
For anything higher than one step. Built on site, with flat landings and rails on both sides.
