STAIR LAYOUT EXAMPLES
Stair Layout Definitions
Rise: The “floor-to-floor” or “landing-to-landing” rise is the actual ver-
tical rise required for building a stairway after the finish flooring has
been installed.
Run: The run of a stairway is the amount of horizontal space
required. The total run of a stairway is equal to the width of each
tread multiplied by the number of treads.
Desired Riser Height: The desired riser height is the amount of
vertical rise you allow for each individual riser in the stairway. This
is sometimes dictated by local code.
Actual Riser Height: The actual height of each riser is measured
from the top of one tread to the top of the next tread.
