What is the size of stair steps?

What is the most comfortable stair rise and run?
With a riser height of 7 1/2 inches, tread width (run) should be at least 9 inches. Ten inches is a more comfortable run; when you multiply 7 1/2 inches by 10 inches, you get 75 — within the conventional ratio of 72 to 75 inches. With 14 10-inch treads, the total run of the stair will be 140 inches.

Can the bottom step be a different height?
Yes, the last tread to landing doesn’t “count”, but if it’s going to be too odd for more than 3/8″ between steps, it’ll be REALLY odd to have 1+” diff between last step and landing.
