all of these sizes are acceptable

Answer 24

all of these sizes are acceptable

For most stairs, a 7″ (178 mm) riser and 11″ (279 mm) tread is a good combination and satisfies the code. IBC limits risers to 7″ (178 mm) in most stairways and 7.75″ (197 mm) in residential stairways.

The minimum tread depth by code is 11″ (279 mm), or 10″ (254 mm) in residential stairways.
