How To Figure Stairs For Deck
Total Run G - The Total Run is the horizontal length of a stair stringer.
How to figure stairs for deck. We suggest 105 for 2x12 or 2 - 2x6 Treads. Your preferred ending riser height in inches. Your second balusters front edge will sit on the middle mark of the tread.
So to calculate the number of treads steps you will need we simply take the height to deck measurement and then divide this figure by 175 rise height. Brought to you by a Journeyman Carpenter I pack this video full of all the info and math you need to build a set of deck stairs OR a simple set of interior. Place your first baluster at the edge of the tread flush with where the riser meets the tread.
Having a stable sturdy set of stairs leading to and from your deck is one of the most importantand complexparts of the deck building process. It is pretty much a series of small decks layered. The Total Rise should be not larger than 151 inches 3835 mm between landings or floor levels.
To calculate the stringer length follow this formula. Determine the exact width of your stair tread. Treads may be cut to suit other widths.
For larger stairs divide by 6 and for smaller stairs divide by 7. Mark the middle point of the tread do not count the lip of the tread that overhangs the riser.

Determine the Rise and Run To determine the rise and run of the steps measure the distance from the floor of the deck to the ground and divide that number by 75. It is equal to the number of treads multiplied by the typical Tread Depth B. Even though we have based the calculations on the IRC you must always check with local building codes to ensure there are no variances.
