How it is calculated

Walls: 2 × (10 + 14) × 8 = 384 sq ft
Minus door and windows: 384 − 50 = 334 sq ft
Two coats: 334 × 2 ÷ 350 = 1.91 gallons → 2 gallons
Ceiling: 10 × 14 = 140 sq ft → 140 × 2 ÷ 350 = 0.8 gallons

Tips for a 10x14 room

  • You need 1.91 gallons, so 2 gallons leaves about 0.4 quarts spare – enough for touch-ups. Do not bother with a 5-gallon bucket.
  • Cutting in with a brush runs 48 ft along the ceiling line and another 48 ft along the baseboards, before counting door and window frames.
  • The 140 sq ft ceiling needs only 0.8 gallons for two coats, so a quart or a gallon of ceiling paint is plenty.
