Drywall and plaster quantities.
Measure boards, joint runs and each coat surface separately. Use the fixing pattern already specified for your project.
Gather the selected product data
Keep compound tubs, adhesive cartridges and different plaster products separate. Wet volume and mixed bag yield must use the same basis.
Choose the matching calculation
Specified Drywall Panel Screw Grid Calculator
Count mathematical perimeter and interior screw positions on identical panels using your supplied grid, with corners counted once.
Specified Drywall Adhesive Dab Volume Calculator
Convert an explicitly specified dab grid and cylindrical wet dab dimensions to cartridge quantity.
Separate Plaster Coat Product Bag Calculator
Order each separately specified plaster product from its measured area, coat depths and mixed bag yield.
Tapered Joint Compound Wet Volume Calculator
Calculate compound for a supplied trapezoidal wet joint-band cross-section along measured joint lengths.
Measure and check your assumptions
How to measure and order: drywall and plaster quantities
Which measurements and product data prevent quantity mistakes for this job?
Separate coat products versus pooled material volume: quantity checks
Different plaster products require separate bag rounding even when their combined wet volume appears convenient.
Compare purchase scenarios
Keep the estimate within scope
Supplied screw grids, adhesive dabs and coat thicknesses are arithmetic inputs, not recommended installation schedules.
Collect chosen results in a free browser material project. Alternative scenarios remain separate orders.
