About this tool

Estimate drywall sheets, screws, mud and tape for walls and ceilings.

How to use Drywall Calculator

  1. Enter the total wall length, height, doors and windows, and the ceiling if needed.
  2. Choose the sheet size and waste.
  3. Read the sheets, screws, compound and tape.

Worked example

A 14 × 10 ft room with 8 ft walls, two doors and two windows needs about 13 sheets of 4 × 8 drywall.

Which sheet size is best?

Larger sheets mean fewer seams to tape but are heavier to lift; 4 × 8 is easiest to handle.

How much waste should I add?

About 10% for cuts around openings.
