How it is calculated

Walls: 2 × (14 + 16) × 8 = 480 sq ft
Minus door and windows: 480 − 50 = 430 sq ft
Two coats: 430 × 2 ÷ 350 = 2.46 gallons → 3 gallons
Ceiling: 14 × 16 = 224 sq ft → 224 × 2 ÷ 350 = 1.28 gallons

Tips for a 14x16 room

  • You need 2.46 gallons, so 3 gallons leaves about 2.2 quarts spare – enough for touch-ups. Do not bother with a 5-gallon bucket.
  • Cutting in with a brush runs 60 ft along the ceiling line and another 60 ft along the baseboards, before counting door and window frames.
  • The 224 sq ft ceiling is large enough to justify a roller extension pole and a dedicated ceiling paint – count on 2 gallons for two coats.
