Painting Calculators
Convert room dimensions, coats and expected coverage into paint quantities and whole-container orders. These paint calculators cover walls, ceilings, primer, trim and doors across multiple rooms.
Available calculators
1 live toolKeep finish surfaces and independently selected primer scope organized by room and specification.
- Paintable SF and coat-SF
- Required gallons and gallon/pail orders
- Independent primer surface scope
- Optional openings, trim and doors
Coverage and allowance are editable project assumptions, not universal product ratings.
Open CalculatorSeparate surfaces and specifications
Wall and ceiling finishes remain separate takeoff lines. Primer can follow enabled finish surfaces or explicitly cover walls, ceilings or both independently.
Identical rooms within one entry multiply before container rounding. Separate room entries round independently, which is useful for organizing different paint specifications.
Look beyond gallons for the complete bid
Drawing-based painting takeoffs review finish schedules, substrates, coatings and locations. Preparation, protection and access requirements may affect the project estimate beyond the calculator’s quantity scope.
Use room calculations for paint planning, then review the plans and specifications to define the entire painting scope.
