How we build a closed in riser stair for decks with a skirt for solid railings

Deck stair total rise table with calculations for riser heights and number of treads

EXAMPLE: A total rise of 5 feet would give you 8 rises at 7 1/2 inches or 9 rises at 6 11/16 inches.
There is always one less tread so if there is 8 rises, then there is 7 runs.
