What do you call a landing on stairs?

It is technically called a “landing”, although most people think of landings as midpoints in a flight of stairs. Building codes require landings at the top and bottom of each flight, to safely allow people using the stairs to exit from the flight and begin horizontal movement again.

What happens if there are too many stairs in a flight?

If there are too many stairs (or steps) in a single flight (without being broken up by landings) it can be tiring to walk up, disorientating to walk down, and if there’s a fall, increases the risk that there will be a serious injury. Too few and the staircase will take up significantly more space, as well as being slower to ascend and descend.

Type of stair

The type of stair is given based on its design and utility.

Straight stair

Straight Stair

This type of staircase is arranged directly between the two floors. This type of stair is used for small buildings. Also used where space is not available.
