What length of ramp do I require?
Length of ramp = Chosen Gradient x Height (Change in level)
Chosen gradient = 1:10
Height = 150mm (6”)
Length required = 10 x 150mm (6”) = 1500mm (60”)
Choose a ramp with a minimum length of 1500mm (60”)
Remember – Consider the available space and choose the longest ramp possible as this achieves a shallower gradient and is easier to climb.
What gradient will I achieve with a specific ramp?
Gradient = Length of ramp DIVIDED BY Height (Change in level)
Length of chosen ramp = 1800mm (72”) DEVIDED BY Height = 300mm (12”)
Gradient = 1800mm (72”)
= 6 (1:6 gradient)
Check the achieved gradient against the Gradient Guide to be sure that it is appropriate for the intended use.
