About Drywall Estimator
The drywall estimator turns a wall into a shopping list: boards, screws, joint compound, and tape. Enter the wall area directly or from length and height, subtract openings, choose whether one or both sides get boarded, pick a board size, and set a wastage percentage for cuts.
The consumable rates are the ones the trade uses for taped and finished joints: about 14 screws per square meter (a standard fixing pattern on studs), 0.5 kg of joint compound per m², and 1.5 m of joint tape per m². Board count is the net area with wastage divided by your chosen sheet size, rounded up to whole boards.
Use it to estimate a partition, a garage conversion, or a whole-room reboard before the builders’-merchant run — free, live in your browser. The figures assume standard single-layer boarding; fire- or sound-rated double layers simply mean running the numbers twice.
