Plywood and Joist Calculator

The Plywood and Joist Calculator is great for estimating the number of sheets of plywood that you might need as well as the number of screws needed to secure the plywood. This contractor calculator can also estimate the number of studs and joists you may need as well as the number of planks of wood you would need for the top and bottom plates. All of the results that you get from the calculators are assumed to be round numbers and should have an additional 5% or more contingency value added by you for a proper plywood and joist estimate.
