Explanation of Measurements
1 - Overall Length of Staircase
Note: This should be a straight measurement from
the nose of the top step to the floor, at the foot of the stairway.
2 - Staircase Width
Note: You many find that your staircase width
varies a little, over the length of the stairway. Record the measurement
at its narrowest point.
3 - Clearance at Bottom of Staircase
Note: A minimum of 24" (61cms) is required for
this measurement.
4 - ‘Rise’ of One Step
Note: Height of one step. This may vary
slightly, so measure several steps part way up the stairs and take an
average.
5 - ‘Tread’ of One Step
Note: Depth of one step. This may vary slightly,
so measure several steps part way up the stairs and take an average.
6 - ‘Diagonal' of One Step
Note: Distance between the 'noses' of two
ajacent steps. This may vary slightly, so measure several steps part way
up the stairs and take an average.
