How Wide Does A Staircase Have To Be?

Ronnie Maye answered

You can build it as weird as you have room for it as long as you have enough support under it to hold the weight and keep it from sagging. In my part of the country the acerage width is 4 ft.

42" wide perfect yet 36" is least. Tallness is most extreme of 8" (approx, check your neighborhood code) however 7" is more agreeable inside and 6" is better in scene settings. Profundity again is code directed, however commonly around 11". Trust that makes a difference!

Check for local sources for local regulations.

As an example, the legal minimum in New York seems to be 48":
