Calculate stair stringers.

The stringer mount type refers to how the stringer will be attached to the upper landing or deck frame. How to calculate stairs. Stringer length depends on both the height and run of the stairs you intend to build as well as the intended tread and rise of each individual step on the staircase. Building stairs for your deck is often considered the most difficult part of the construction project.

The total vertical distance that a staircase will cover. 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. The program generates the results of the calculations of the 3d model straight staircase drawings of all structural elements with straight stair stringers. Having the right calculations before getting started can make the task a lot easier.

This free stair calculator determines stair parameters such as rise total run and angle stringer length based on height run tread and headroom requirement. 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. The main framing member that runs at a diagonal and supports the stairs. Easy to use free stair calculator by ez stairs.

Explore a number of building and housing related calculators as well as hundreds of other calculators involving topics such as finance math fitness health and more. Once the stair results have been calculated you can toggle between the standard and flush options to compare the differences. To find the height extend a level out across the upper edge of the entry point and stretch a tape measure from the bottom of the board to the ground. Total run the total horizontal length of the stair stringer.

For wooden stairs select stringer width and enter the width of the stringer. Provides a step by step display and a print out option showing the finished stringer with cut dimensions and a materials list. To use our stair calculator you need to enter the following measurements as a minimum. In this case we are laying out and cutting an open stringer which is cut in a stepped pattern of vertical and horizontal cuts.

Before you begin building your stairs or steps you must calculate the length of your stair stringers as well as the measurements of individual steps that will set into the stringer. Total rise the vertical height between the bottom of the first step and the top of the final step in the stair stringer.
