Paint Calculator
Paint quantity, containers, and rough cost.
Paint Calculator
Estimate paint for room walls, single walls, ceilings, exterior walls, fences, and trim. The calculator keeps quantity math deterministic and can also turn coverage into a container count and rough cost.
Paint Inputs
Room and ceiling modes use room dimensions. Wall, fence, exterior-wall, and trim modes use surface length and surface height. Deduction area is optional and can stand in for doors, windows, or skipped sections.
Paint calculator FAQ
Why does the calculator ask for coats?
Because total paint needed depends on the full coat area, not just the base wall area.
What should I put in deduction area?
Add the total area of windows, doors, or sections you do not plan to paint. Leave it blank if you want a full-surface estimate.
