How it's calculated

  • Wall sheets = length × height × sides ÷ area of one sheet (4x8 = 32 sq. ft), + waste, rounded up.
  • Ceiling sheets = ceiling area ÷ area of one sheet, + waste, rounded up (calculated separately from the walls).
  • Taping = drywall area of the walls + ceiling area, no waste.

Measure once. The rest follows.

In KOR, this calculation happens on its own from your plans: measure the wall once, and the framing, drywall, taping, insulation and paint follow.
