staircase is a simple and elegant way for people to move between floors. The layout, design and execution by the builder all play a part in determining how safely and comfortably a stair accomplishes this task.
Lingo to know:
Tread: The horizontal board you walk on, usually at least 1 inch thick
Riser: The vertical board between treads
Newel: The post to which the railing is attached
Runner: A carpet with woven edges that covers the middle of the treads and risers
Stringer: The supporting structure of the stair

The horizontal distance from the front to back of the tread is called the run, and the vertical distance is the rise. As you will have noticed from the staircases you've walked on, the rise and run can vary.
Rise-to-run ratio. The total of the rise and run should add up to 17 inches. Practically speaking, this means that as the run gets shorter, the rise should get steeper for the stair to feel comfortable as you walk. There are limits, of course. A rise of more than 8¼ inches is going to be too steep for many people
