How Many Stair Treads or Steps Does The Average Stairway Have For Two-Story House?

The average stairway for a two-story house will have 13 steps and 14 risers. This is based off of an 8 foot tall ceiling and the use of 2 x 10 or 2 x 12 for floor joist.

However, today newer two-story homes are being built with nine and 10 foot ceilings. Stairways for buildings this tall would require 14 to 17 steps.

Don't forget to count any landings or floors in between the first and second story as steps.

For example, the stairway in the picture above has a step in the landing and would be counted as two individual steps. Any change in vertical height around 90° should provide you with another step.
