DrywallCalc
Calculate sheets

Several measured surfaces

Drywall for walls and ceilings

Add each distinct width and height, use quantity for matching surfaces and include the ceiling only when it is part of this purchase.

Keep the surface list visible

Each row contributes width × height × quantity. Separate rows make different room sides and a ceiling easy to review before calculating.

Use gross area

DrywallCalc does not subtract doors or windows. Cut sheets are still required around openings, and an area-only calculator cannot prove that every offcut will be reusable.
