Estimate painting costs and how many gallons you need.
How much does interior painting cost?
Professional interior painting costs $2–6 per square foot of wall area, depending on prep, quality, and number of coats.
How many gallons of paint do I need?
One gallon covers approximately 350–400 sqft. Add 15–20% for two coats and allow for trim and touch-ups.
What is the difference between standard and premium paint?
Premium paint has better coverage, durability, and washability. It costs $60–80/gallon vs $30–45 for standard, but often requires fewer coats.
How long does interior painting take?
A typical room takes 4–8 hours for a professional crew including prep, painting, and cleanup. Full house projects range from 2–5 days.
Should I paint before or after flooring?
Paint before installing flooring to avoid drips on new floors. Repaint baseboards after flooring is installed if needed.
