Measuring Stair Stringers

They support the treads and provide the structural support of the stairway.

Measuring stair stringers.

The stringer mount type refers to how the stringer will be attached to the upper landing or deck frame. In order to cut your stair stringers perfectly you need to take the time to measure and lay them out correctly. Having the right calculations before getting started can make the task a lot easier. 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.

Test fit the stringer to make sure your stair rise and run are on point. There are three main components in a standard staircase. Stringers risers and treads. Treads may be cut to suit other widths.

We suggest 10 5 for 2x12 or 2 2x6 treads. This free stair calculator determines stair parameters such as rise total run and angle stringer length based on height run tread and headroom requirement. Calculate your staircase s stringer length. 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.

Building stairs for your deck is often considered the most difficult part of the construction project. Stair stringers are the backbone of any set of stairs. 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.

Test fit the stair stringer by placing it against the deck and check the tread level with a small level. Either b or c is required. Stringers run diagonally along the length of each stair to prevent them from collapsing. Determine the total rise for your stairs using a level and a tape measure.

Cut only the top and bottom of the stair stringer with a circular saw. From there find the square root of the answer for the length of each stringer. The stringer is the backbone of the structure. Be sure to test fit the first stringer before you cut the others.

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. 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. To determine their length square the run square the individual stair rise and then add the 2 numbers together. How to measure stair stringers by ian h caldwell things you ll need.

Measure the distance from the top of the deck surface to the top of the stair landing.
