Calculate drywall square footage for walls, ceilings, rooms, basements, garages, and remodeling projects. Estimate drywall sheets, openings, waste, joint compound, tape, screws, and project cost.
Room walls mode:
The calculator uses room perimeter times wall height, then subtracts doors and windows.
Walls and ceiling mode:
The calculator adds wall area and ceiling area before subtracting openings.
Single wall mode:
The calculator multiplies wall length by wall height and the number of same-size walls.
Known area mode:
The calculator starts with your known drywall area and estimates sheets, waste, compound, tape, screws, and cost.
A drywall area calculator helps estimate square footage for hanging drywall in bedrooms, basements, garages, ceilings, remodels, additions, and new construction.
It can help calculate wall area, ceiling area, opening deductions, drywall sheets, joint compound, drywall tape, screws, waste, and estimated cost.
Your result shows gross drywall area, door and window opening area, net drywall area, area with extra waste, drywall sheets needed, joint compound buckets, tape rolls, screw count, and estimated cost.
Calculate the wall and ceiling areas that need drywall, then subtract doors, windows, and other openings. Add waste before estimating sheet quantity.
A 4 by 8 sheet covers 32 square feet, a 4 by 10 sheet covers 40 square feet, and a 4 by 12 sheet covers 48 square feet.
Yes, subtracting openings can improve the estimate. For small jobs, some people leave small openings in the estimate to help cover waste and cuts.
Many drywall projects use about 10% extra. Rooms with closets, many openings, angled walls, stairways, or unusual layouts may need more.
No. It is an estimate. Actual drywall needs vary by sheet layout, framing, ceiling height, cuts, seams, damage, waste, installer method, and local project conditions.
