Calculate Stair Stringers

For wooden stairs select stringer width and enter the width of the stringer.

Calculate stair stringers.

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. For concrete stairs select concrete thickness and enter the throat thickness see diagram and stair width to calculate formwork dimensions and concrete volume. In this case we are laying out and cutting an open stringer which is cut in a stepped pattern of vertical and horizontal cuts. Total rise the vertical height between the bottom of the first step and the top of the final step in the stair stringer.

Building stairs for your deck is often considered the most difficult part of the construction project. 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. 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. The main framing member that runs at a diagonal and supports the stairs.

Once the stair results have been calculated you can toggle between the standard and flush options to compare the differences. To simplify the process we ve created this deck stair calculator to help you determine the correct measurements needed to carry out your project. The stair stringer calculator allows you to perform online calculation of straight staircases on strings. 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. 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. The total vertical distance that a staircase will cover. 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.

How to calculate stairs. The total horizontal distance that a staircase will cover. The program generates the results of the calculations of the 3d model straight staircase drawings of all structural elements with straight stair stringers. This free stair calculator determines stair parameters such as rise total run and angle stringer length based on height run tread and headroom requirement.

Having the right calculations before getting started can make the task a lot easier. The stringer mount type refers to how the stringer will be attached to the upper landing or deck frame.
