Paint Coverage Guidelines

Different paint types and qualities cover different amounts of area per gallon:

  • Economy Paint: 250-300 sq ft per gallon
  • Standard Paint: 350-400 sq ft per gallon
  • Premium Paint: 400-450 sq ft per gallon
  • Primers: 200-300 sq ft per gallon
  • Textured/Specialty Paints: 175-250 sq ft per gallon

Tips for a Successful Paint Job

  • Always buy a little extra - Having some leftover paint is better than running short
  • Consider the surface texture - Rough or textured surfaces require more paint
  • Account for the existing color - Darker colors covering lighter ones may need fewer coats
  • Don't forget primer - New drywall or significant color changes often require primer
  • Use high-quality brushes and rollers - They apply paint more efficiently
  • Measure ceiling height from floor to ceiling - Don't estimate
