Understanding Paint Coverage
Paint coverage varies depending on the type and brand of paint, as well as the surface you’re painting. On average:
- Interior paint covers about 350-400 square feet per gallon.
- Exterior paint covers approximately 250-400 square feet per gallon.
Our calculator takes these factors into account to provide an accurate estimate.
Factors Affecting Paint Quantity
Several factors can influence how much paint you’ll need:
- Surface texture: Rough surfaces require more paint.
- Color change: Dramatic color changes may need additional coats.
- Paint quality: Higher quality paints often have better coverage.
- Application method: Spraying typically uses more paint than rolling or brushing.
Tips for Accurate Measurement
To get the most precise estimate:
