Ramp Gradient & Ramp Length Calculators
At Access All Ways, we’re committed to making accessibility simple and compliant. Whether you’re designing a new access ramp or checking an existing one, our online calculators help you get the right gradient or length quickly and accurately — in line with AS 1428.1 accessibility standards.
Ramp Gradient Calculator
Use the Ramp Gradient Calculator to determine the slope of your ramp. Just enter the total height of your steps or threshold and the length of the ramp, and you’ll instantly get:
-
Gradient as a Ratio (e.g. 1:14)
-
Gradient as a Percentage (e.g. 7.14%)
-
Gradient in Degrees (e.g. 4.08°)
This is useful for checking compliance, especially when building ramps for wheelchairs, trolleys, or general access improvements.
Ramp Length Calculator
Not sure how long your ramp needs to be? Enter the height of your steps and your desired gradient (e.g. 12 for a 1:12 slope), and the calculator will tell you the exact ramp length required in millimetres. This is ideal for planning new constructions or retrofitting accessible entrances.
