The total rise of the stairs is the height between floors (or landings) that the flight of stairs is spanning. If there are N steps, the total rise equals N times the rise of each step. The slope or pitch of the stairs is the ratio between the rise and the going (not the tread depth, due to the nosing).
In theatre, a platform (also referred to as a riser or rostrum) is a stationary, standard flat walking surface for actors to perform on. Typically, they are built to be assembled modularly. Typically, they are built to be assembled modularly.
The nosing is the protrusion beyond the riser when vertical risers are used, or beyond the back of the tread below, when angled risers or no risers are used.

(This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run.) as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentage "grade" is the most commonly used figure for describing slopes.
