How this drywall screw calculator works

Drywall area is multiplied by the selected screws-per-square-foot rate, then increased by the extra allowance and rounded up.

How to use it

  1. Drywall area. Enter the value in sq ft.
  2. Screws per square foot. Enter the value that applies to your situation.
  3. Extra allowance. Enter the value in %.
  4. Request the result. Add your email, then select “Email & show my result.”

What to do with the number

Fastener spacing varies with framing, panel orientation, ceiling use and local requirements, so this is a material takeoff rather than a fastening schedule. Use the fastening schedule for your drywall thickness, framing type and installation method to choose the screws-per-square-foot rate.

Planning estimate

Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
