12 × 14 ft room: the short answer

With an 8 ft ceiling, a 12 × 14 ft room has about 584 sq ft of drywall including the ceiling — roughly 21 sheets of 4×8 at 10% waste, or 15 sheets for walls only.

Don't forget the finishing

Beyond the sheets you'll need about 2 boxes of joint compound, ~234 ft of tape, and ~672 screws. Subtract big openings in the calculator, and bump the waste allowance for rooms with lots of cuts.

What a 12 × 14 ft room needs

A 12 × 14 ft room is a medium bedroom, family room, or home office. At an 8 ft ceiling it needs about 52 sheets of drywall including the ceiling, a quantity where layout planning and a helper are worth arranging before the first sheet is cut.

How to decide

At this size, buying one extra sheet for mistakes is cheaper than a second trip, but avoid over-ordering by planning the layout first. The calculator gives the wall-perimeter count with 10% waste; subtract windows, doors, and any pre-finished wall sections. Larger sheets reduce vertical seams on the 14 ft walls if handling is feasible.

Checks before you order

  • Plan seams to fall on framing, not floating between studs.
  • Subtract all openings before confirming the sheet count.
  • Arrange a helper and consider a drywall lift for ceiling panels.
