Staircase Basic Details | Staircase Design





This video tutorial sheds light on the various components of the staircase, in addition, it gives some basic info and illustrations.

A flight of staircase consists of different horizontal and vertical surfaces. The vertical surface is called the riser and the horizontal surface is called tread. Through integrating both of them a step is made. With the combination of series of steps, it becomes less difficult to move from one level to another.

The rise is how tall a step is. The horizontal dimension that is enclosed in a single step is known as going.



The slope or pitch of the stairs is the ratio between the rise and the going (not the tread depth, due to the nosing). It is sometimes called the rake of the stairs. Up to a maximum of 45 degrees is permitted for pitch.

The total run or total going of the stairs is the horizontal distance from the first riser to the last riser. It is often not simply the sum of the individual tread lengths due to the nosing overlapping between treads.

On arrival the following level, one puts its steps first at the landing and each staircase includes a handrail mounting together with it. A person who intends to move upward can put it to use as a help. The height of the handrail is calculated with the intersection point of the riser and tread.
