STEP CALCULATOR
CALCULATE THE RISER HEIGHT & TOTAL NUMBER OF STEPS
1. Calculate the finished floor level
Take a measurement from the ground level to the bottom of the door using a measuring tape and spirit level (optional).
The below diagrams demonstrate this. Your door may open inwards or outwards; both options are shown.
2: Using the calculator
Input your finished floor level (FFL), then follow the guidelines to discover the correct riser height and the total number of steps and risers required.
