Winders are steps that are “in” the landing. More accurately, they are in the place where the landing would be if you had one. The advantage is that you gain “rise” in a space that otherwise would remain at one level. This shortens the overall staircase length and can greatly increase design flexibility.

While they can be used as a unique architectural element in your home, winders are also very useful as a space saving (or space accommodating) fixture in your stair: where a landing acts as a single tread, a winder incorporates 3 treads in the same space.
How do you calculate flights of stairs?
A flight of stairs is generally the height of the ceiling plus the framing and subfloor of the floor above where the stairs end. In a space with 8 feet ceilings, a flight of stairs is anywhere from 8 feet 8 inches to just over 9inches high.
