To build basic wood steps, collect tools and materials, calculate the steps rise and run, cut a pair of stringers, cut treads and risers, and then attach the treads and risers to the stringers. Once the steps have been constructed, mount or attach them to the landing, deck or surface they are intended for.
Assemble tools including hammer, drill, hand saw, tape measure, framing square, nails and screws, as well as good quality lumber such as cedar boards. Then, calculate the rise and run by measuring the distance from the top to the bottom of the intended set of stairs in inches and then divide by seven, which is the average height of a safe step. Round this number up or down to calculate the necessary number of steps. Then, take the number of steps and divide the total height of the steps to discover the actual rise of each step.
Using the tape measure and framing square, measure and cut the shape of the stringers with the calculated rise and run. Measure the thickness of the piece of wood that will be used as the tread, then cut this measurement off the top of each rising step. Decide the width of the steps then measure and cut the treads and risers.
After measuring both stringers and cutting and accounting for the treads, drill or nail the treads and risers to the stringers to connect them.
