Measuring Stair Stringers

Stair stringers are the backbone of any set of stairs.

Measuring stair stringers.

We suggest 10 5 for 2x12 or 2 2x6 treads. Stringers run diagonally along the length of each stair to prevent them from collapsing. They support the treads and provide the structural support of the stairway. To measure stair stringers start by dividing the height by the approximate rise to determine the total number of steps and then take the difference to find the exact rise of each step.

To determine their length square the run square the individual stair rise and then add the 2 numbers together. From there find the square root of the answer for the length of each stringer. Determine the total rise for your stairs using a level and a tape measure. Be sure to test fit the first stringer before you cut the others.

Enter total stair rise inches. Stringers risers and treads. Once the stair results have been calculated you can toggle between the standard and flush options to compare the differences. Either b or c is required.

Test fit the stringer to make sure your stair rise and run are on point. Building stairs for your deck is often considered the most difficult part of the construction project. The stringer mount type refers to how the stringer will be attached to the upper landing or deck frame. This free stair calculator determines stair parameters such as rise total run and angle stringer length based on height run tread and headroom requirement.

Cut only the top and bottom of the stair stringer with a circular saw. Since the tread depth b is a constant when using the automatic stair calculator the total run g will vary when you toggle between the two mount options. There are three main components in a standard staircase. Test fit the stair stringer by placing it against the deck and check the tread level with a small level.

The stringer is the backbone of the structure. How to measure stair stringers by ian h caldwell things you ll need. The above example shows. Measure the distance from the top of the deck surface to the top of the stair landing.

Having the right calculations before getting started can make the task a lot easier. Calculate your staircase s stringer length. Treads may be cut to suit other widths. To simplify the process we ve created this deck stair calculator to help you determine the correct measurements needed to carry out your project.

Stringers are the diagonally placed boards anchored at the top the header and the bottom.
