According to Wonderopolis, a flight of stairs does not contain a particular number of stairs or steps. The number of steps in a flight varies widely from building to building, and flights of stairs in a building also vary by the number of steps included in a flight.
A flight of stairs is defined simply as an uninterrupted set of steps between two floors or even between two landings. The use of the word "flight" to describe a set of stairs between floors in a building is a metaphor for taking flight in an upward journey. The longest stairway in the world is made up of 11,674 steps, according to the Guinness Book of World Records.
