What Is Considered a Flight of Stairs?
Have you ever heard of a “flight” of stairs? This term is defined as an uninterrupted series of steps. This can mean the set of stairs between floors or those between landings. There’s really no set rule for what can be called a flight of stairs.
Uses of Flight of Stairs
The primary purpose of stairs is to provide a simple and easy means of moving between levels. In ancient times, houses and shelters were made up of only one storey, but it was realised that the area above ground level could be utilised to increase the amount of space a structure could offer.
How Many Stairs Are in a Flight?
If you’ve ever wondered how many stairs are in a flight, a flight of stairs has 13 to 16 steps on average based on today’s ceiling heights in most residential buildings and the type of staircase.
Types of Stairs
- Straight. This one is straightforward (literally).
- L-shaped (a.k.a. quarter-turn) The classic straight style, zhuzhed up a little.
- Winder. The slightly more complicated sister to the L-shaped staircase.
- U-shaped (a.k.a. half-turn)
Flight of Stairs Definition

Zero Force Members
If a joint has only two non-collinear members and there is no external load or support reaction at that joint, then those two members are zero- force members. In this example members DE, DC, AF, and AB are zero force members. Again, this can easily be proven.
