Pro Painting Tips
Primer Requirements
Always use primer on new drywall, patched areas, or when painting over dark colors. Add an extra coat to your calculation if priming is needed.
Standard Openings
This calculator assumes standard doors are 21 sq ft (1.95 sq m) and standard windows are 15 sq ft (1.4 sq m).
Texture & Finish
Rough surfaces like stucco or heavily textured drywall will absorb more paint. Consider decreasing the "Coverage per Gallon" by 20% for these surfaces.
Leftover Paint
It's good practice to keep some leftover paint for future touch-ups. Buying a full gallon instead of a quart is often more cost-effective.
