Exterior stairs
I just had exterior stairs completed (brick and limestone) from street level to parlor (front of house). I feel the contractor did not give me enough step size. These stairs look steep and have small space to step on each step. Going up you have 91/2” to 10” foot space with 9”height. Going down you have 71/2” to 8” foot space. Thread nose overlaps next step by about 2”. Does any one know what dimensions does code require?

From wikipedia, subject "Stairway":
Ergonomics and Building Code requirements
"Minimum tread length, typically 9 inches (229 mm) including the nosing. However, most human feet are longer than 9 inches (229 mm), thus people's feet don't actually fit on the tread of the step."
the link to that page (containing lots of additional info regarding stairs) is:
