How to get drywall sheets for your next construction project


Calculate how many drywall sheets your project will need

Measure the area that you will be placing your drywall sheets on. Then enter your measurements into Billd’s drywall calculator.
This calculator assumes that you are using 4’ x 8’ drywall sheets and that you have an average waste factor of 10%, which is on the low end. Meaning that you will lose 10% of your drywall sheets when you cut and configure your drywall to install on a wall, subfloor, or wherever else you may need drywall sheathing.
The calculator works by using the equation below:
Width (Feet) X Length (Feet) x 1.1

32 SF =Total sheets of drywall rounded to the nearest number

The estimated cost is based on the average cost of drywall of between $15 and $20 per 4’x8’ sheet. The price of drywall depends on a variety of factors including:
