Is 45 degrees too steep for stairs?

Stairs are typically not defined by angle but by the size of the treads and risers. Using those dimensions a stair at 45° would have 7″ treads (too small) with 7″ risers or 11″ treads with 11″ risers (too big). So yes, a 45° stair is too steep and more importantly doesn't even come close to meeting the building code.

What is the formula for building steps?

Determining the Rise You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you'll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).

What is a standard step height?
