STAIR LAYOUT EXAMPLES
STAIR LAYOUT DEFINITIONS
Rise: The “floor-to-floor” or “landing-to-landing” rise is the actual vertical
rise required for building a stairway after the finish flooring has been in-
stalled.
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 verti-
cal rise you allow for each individual riser in the stairway. This is some-
times 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.
