Calculate how many balusters you’ll need for a deck or stair railing by entering the railing length, baluster width and spacing. Multiple rail sections can be entered. Can use inches or centimeters. The results will show how many balusters are needed for each section and the location that each baluster should be attached to meet the proper spacing. Making sure your structure is compliant with local building codes is important and this App will help get the proper spacing. The calculated results can be emailed or texted as needed.
