Paint Coverage by Room

Estimate paint coverage for bedrooms, bathrooms, kitchens, living rooms, and small repainting projects.

5 min read

Bedrooms and living rooms

Bedrooms and living rooms often have larger continuous wall areas. Measure each wall, subtract large openings if needed, and plan for two coats when changing color.

Bathrooms and kitchens

Bathrooms and kitchens may have less paintable wall area because of cabinets, tile, mirrors, and fixtures. They may also need paints suited for moisture and cleaning.

Hallways and small spaces

Small spaces can still use more paint than expected if they have many corners, doors, trim interruptions, or textured surfaces. Measure instead of guessing by room name alone.

Use coverage as a range

A label coverage number is a good starting point, but real use changes with surface condition, roller nap, primer, repairs, and color shift. Round up before buying.

Planning checklist

Before you make the final plan

  • Measure the real surfaces you plan to paint, including walls, trim, doors, and repaired areas separately.
  • Check product coverage, dry time, sheen, primer needs, and surface preparation before buying.
  • Plan supplies such as tape, rollers, brushes, trays, drop cloths, sanding blocks, and cleanup materials.
  • Use calculator results as a planning baseline, then compare with the label on the exact paint you choose.
