Nosing: The nosing is the protrusion at the edge of a tread that hangs over the riser below. Maximum total rise between landings: no more than 147 inches (3734 mm). Today is part two on how to figure and cut stairs for the first time. Rise/riser: the vertical part of the stairs, measured between two consecutive treads.

You probably noticed that whether you want to calculate the stair stringer, the rise, or the run, you will at some point encounter the phrase "number of stairs". Staircase width (important not only because of comfort, but also for safety): no less than 36 inches (914 mm). You'll also want to determine where the stairs have to be placed, then measure out a depth for each stair such that a person can safely walk up and down the flight without falling. Start on the lower left and fill in that square for the first step. The fastest way is to use n(n + 1) / 2.

If you plan to use balusters or spindles for your stairs, make sure that you use vertical balusters and not mid-rails!

Cut the last riser and the last tread lines all the way across the board to create the angles necessary for the stringer to lie flat against the ground and against the landing. wikiHow marks an article as reader-approved once it receives enough positive feedback. For example, the 2nd figure is made up of 4 squares. Today is part one of a two part series on how to figure and cut stairs for the first time. Then devise as many general methods as you can for predicting the number of blocks in any staircase. I used the latter to reason out potential equations. Set the square onto the two-by-twelve, with its point -- the intersection of the two legs -- facing away from you. >> 7 0 obj 0000087913 00000 n If this is the case, you probably forgot about one tiny thing called comfort of use.

Refer to the figure adjacent to the calculator as a reference. As you did for the step measurements, round the landing measurements up to the nearest foot (or to the next 30 cm, if you prefer metric measurements). Building codes generally suggest that the thread has a minimum length of 10 inches (25.4 cm). This is. Finally, you can find the angle at which the staircase is inclined: angle = arcsin(stringer height / stringer length). /I1 11 0 R Mathematically justify your answer. Count the total number of stairs and record that number. First time building stairs? 0000075993 00000 n A builders square, also called a carpenters square, makes laying out stair stringers a quick task. What's the stringer height? Cutting further undercuts the board and weakens the stringer. We use cookies to make wikiHow great. /Font << 5. Cut up to the intersection of each pencil line, but stop about an inch or so away. If the rise is 42 inches (110cm) (after subtracting 67 feet (1.82.1m) for headroom) and you want larger stairs, for example, divide 42 by 6.
