How do I calculate how much drywall I need for my wall corners? How do I calculate how much drywall I need for my wall corners?
When ordering material for drywall corners, all you have to do is follow a few basic steps. Start by measuring the surface area of the corners that you want to drywall, i.e. length times the width. Next, multiply the surface area by 1.1. Divide this number by 32 and round the result up to the next whole number. This will give you the minimum number of 4 foot X 8 foot drywall panels you need for your project, as well as slight buffer for errors or damaged boards. If you prefer to work with 4 foot X 12 foot drywall panels, then multiply the surface area by 1.1, and then divide by 48 and round up to the next whole number, to determine how many panels to order.
