Paint Room Calculator

A 12x14 room with 8ft ceilings and 2 coats needs about 3-4 gallons of paint. This accounts for 2 doors (42 sqft) and 2 windows (30 sqft) deducted from the total wall area.

Two coats are recommended for most projects. One coat often shows streaks and uneven coverage. Use primer first when painting over dark colors, new drywall, or stains.

Flat for ceilings and low-traffic areas, eggshell for living rooms, satin for kitchens/hallways, semi-gloss for bathrooms and trim, and high gloss for doors and cabinets.
