I work in the miscellaneous (stairs, rails, etc.) steel industry, but things might be different in residential. First of all measure the distance from your starting point (floor or ground where your stairs start) to the top of the step landing. This is called the (rise).

You want an even number of risers so alter the up until. Depends on how the steps are done. Measuring and cutting stair stringers for your own DIY deck or porch project may seem complicate but the process is actually quite simple.

Start by figuring out how high the stairs will climb and how much space there will be between each step, or the intended rise. Stair stringers are the backbone of any set of stairs. They support the treads and provide the structural support of the stairway. In order to cut your stair stringers perfectly, you need to take the time to measure and lay them out.

How to Measure Stair Stringers. The stringer is the backbone of the structure. Then measure the total rise to the landing spot with a straight 2×and a 4-ft. Photo 2: Layout the stairs Clamp the stair gauges to the carpenter’s square.

Expert carpenter shows you how to measure out, mark and cut a stair stringer. The essence of laying out stair stringers is straightforward. You use a framing square to draw the stair ’s notches on the stringer , then you cut them out.

If you’ve done the math (it’s grade-school stuff) and the layout right, the tread cuts will be level and the riser cuts plumb. To layout an open stringer , you fist need to determine the total rise and the total run of the stairs. From these measurements you will derive the unit rise and unit run.

Whether you calculate the total rise first or the total run first is sort of a “chicken or egg” question. Use this deck stair calculator to determine the riser height, angle and total run for your stair stringers. The treads are the boards your feet come into contact with as you climb the stairs.

The overall height of the stair is called the rise. The rise will vary depending on the application of the stairs. Outdoor installations may have an uneven landing. Measure the distance from the top of the deck surface to the top of the stair landing. Stairs Calculator to determine the number of stairs , each stair rise and run for laying out your stair stringers.

Input the total rise number into the Decks. The above example shows outside drop-mounted stairs. The returned are the number of steps along with the risers and the angle of the stringer.

A fraction to decimal conversion table for common fractions used in measurements is also provided at the bottom of the page.

The next job is to find the rise of each step. Step 2: Cutting Stringers. Measure the height of the surface which will be used for the stair.

There are the simple ways how to figure stair stringer length. Then, connect to the bottom surface of the stair will be placed. Give the note of the measuring result and calculate the stringer length and the step sizes. After that, divide the height of the stair and determine. The sawn stringer fits under the stair treads and therefore cannot extend above the treads as with a solid stringer.

The builder types in his total rise into the stair calculator and clicks on calculate to find a breakdown of the size and number of stair rises, the size and the number of stair runs and the length to purchase of the material for the stair stringer. In general terms, the length of a stringer for a stairs is inches for every step. For a more precise calculation, you need the know the height of the riser and the width of the tread for the steps.

Measure the run of the stairs where the stringers install from the upper landing to the ground or a deck. Divide the measurement in half to determine the length of each stringer. Three stringers are the minimum for the 32-inch wide stair. Measure down from the top of the deck the distance of riser plus the tread thickness and mark the top tread.

The picture bellow illustrates the rise and going of our stair stringers. To work out the correct size stair stringer , you will need to know your height to deck. The sides of the stairs , or stringers , are cut from 2-by-boards.

Using a framing square, mark out the portions to be cut away from the.
