If you’re thinking about painting your home, one of the most important questions to ask is, “How many square feet does a gallon of paint cover?” Doing it right means no last-minute runs to the store or collecting cans of paint left in the garage. Let’s break it down into simple terms so you can plan your painting project like a pro.
The Basics: How Much One Gallon of Paint Covers
In general, a gallon of paint covers 350 to 400 square feet per coat. This number can vary depending on several factors, but it’s a good starting point. Here are a few examples to help you visualize:
- A small bedroom wall? One gallon should do the job for one coat.
- A large living room? You might need two gallons, especially if you’re doing two coats.
- Painting a ceiling? Don’t forget ceilings tend to absorb more paint, so plan accordingly.
Factors That Affect Paint Coverage
- Surface Type:
- Smooth walls: These will use less paint.
- Textured surfaces: Popcorn ceilings or rough walls? You’ll need more paint because of all the nooks and crannies.
- Color Changes:
- Going from dark to light? Plan for an extra coat to fully cover the old color. Use our guide to pick right paint colors for your home.
- Using bright or bold colors? Some colors (like red or yellow) need extra coats for a smooth finish.
- Paint Type:
- Flat or matte finishes: These tend to absorb more paint.
- Glossy finishes: These go on thinner and might cover more area.
- Primer Usage:
- Using a primer helps the paint stick better and may reduce the number of coats you need, especially on new or patched walls.
Step-by-Step: How to Calculate Paint Needs
- Measure the Area: Measure the height and width of each wall and multiply to get the total square footage. Don’t forget to subtract the space for windows and doors.
- Example: A 10-foot by 12-foot wall = 120 square feet.
- Check the Paint Label: Each can of paint lists its coverage area. Compare it with your calculated square footage.
- Account for Multiple Coats: If your project requires two coats, double your paint amount.
- Add a Little Extra: It’s always smart to buy about 10% more paint than you think you’ll need for touch-ups or unexpected spots.
Real-Life Example
Let’s say you’re painting a standard 12-foot by 12-foot room with 8-foot ceilings. Here’s the math:
- Wall area: (12 + 12 + 12 + 12) x 8 = 384 square feet
- One gallon covers about 350 square feet, so you’ll need at least 1 gallon for one coat.
- For two coats, you’ll need 2 gallons.
Pro Tips for Homeowners to Save on Paint
- Test First: Get a sample can to test the color on your wall. It’ll save you from buying gallons of paint you don’t love.
- Use Quality Tools: Cheap brushes and rollers can waste paint and make your job harder. Invest in good ones for a smooth finish.
- Prep Your Walls: Clean and patch walls before painting to ensure even coverage.
Final Words
Knowing how many square feet a gallon of paint covers will save you time, money, and stress. By understanding the basics and considering the specific needs of your project, you’ll be ready to tackle your painting project with confidence.
