A practical Australian guide to measuring a doorway rise, choosing the right rubber threshold ramp height, checking clearances and creating a stable, slip-conscious transition.
A small step at the front door can make everyday access harder than it needs to be. The right rubber threshold ramp creates a smoother transition for prams, trolleys, walkers and mobility aids while helping protect the doorway. The key is choosing a height that matches the threshold and a slope that suits the way the entrance is used.
1. Measure the rise, not the doorway width
Start by measuring the vertical rise from the lower surface to the top of the threshold. Measure in millimetres at a few points because older floors and door frames are not always perfectly even. Record the highest measurement and choose a ramp made for that rise. A ramp that is too low leaves a lip; one that is too high can rock or stop the door from opening freely.
2. Match the ramp height to a comfortable gradient
Ramp length affects how easy the transition feels. As a practical guide, a longer ramp gives a gentler gradient and more room for wheels to roll smoothly. For a frequently used or public entrance, consider the access requirements in the current AS 1428.1 and any project-specific guidance before ordering. If you are unsure, send us the rise and available length so we can help you compare options.
3. Check width, clearance and door swing
Measure the clear opening and check where the door lands when it swings. The ramp should provide a stable path without catching the door, skirting or nearby trim. Also check that there is enough level space at the top and bottom for a person, trolley or mobility aid to pause safely. For wider openings, two ramp sections may be needed to cover the usable path.
4. Look for grip and a stable fit
Recycled rubber is a practical choice for many Australian entrances because it is durable, weighty and suited to everyday weather exposure. Look for a textured surface and confirm the required slip rating for the site, especially around wet or commercial areas. Place the ramp on a clean, firm and level base; remove loose grit and check that it sits flush before regular use.
Quick measuring checklist
- Measure the highest threshold rise in millimetres.
- Record the usable doorway width and available ramp length.
- Check door swing, clearances and level landing space.
- Consider traffic, weather and the people or equipment using the entrance.
