The Stairs Calculator will give you the length of the stringer underneath the steps in a straight staircase and the optimal number of steps from the values you enter of the total rise, the depth, thickness and the overlap of the steps. You will also get a detailed construction description with photos where all the measurements you need are included together with carpenter's advice when building your new stair.

The construction instruction is located at this web address https://www.byggoteknik.se/build-stairs showing how to build a deck stair. The content can be translated to your language using the integrated Google Translate tool. The calculated values from the Stairs Calculator App will be inserted into the context. You can also print or bookmark the page and all your measurements will be stored for later.

This version is only for metric measurements (meter and millimeter). An Imperial (Feet) version will be published later on.

We appreciate any feedback! Please use the contact form at https://www.byggoteknik.se/kontakt or send a picture of your new stair at stairscalculator@byggoteknik.se and it will be published on the page in a gallery.
