This App is used for finding the measurements needed to construct a Stair Stringer and a Baluster Layout. Measurements are in inches or centimeters. The Stair Stringer calculates stair risers and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. You can select to create stairs for a fixed run length and rise or to find the run length with a fixed rise. You can choose a standard mount where the top step is below the landing or a flush mount where the top step is even with the landing. The Baluster Layout will calculate the number of balusters needed based on the rail length. The results show where to place the center point of each baluster starting from the beginning of the rail.
