Have you ever stood in the paint aisle, wondering how much one gallon of paint can cover? It’s a question that every DIY homeowner has, wondering if they are purchasing too little or too much. The answer? One gallon covers approximately 300 to 400 square feet. However, this figure is subject to change depending on several factors.
In this blog, you will understand everything in simple terms. So, next time, you may buy the proper amount and avoid wasting money.
Paint Coverage: What One Gallon Gets You
On average, one gallon of paint will cover 300 to 400 square feet of primed wall surface in one coat. That is the size of a small room, like a bathroom or a home office.
But coverage may depend on different factors:
-
Surface Texture
Smooth walls are best for maximizing coverage. However, if you paint over uneven surfaces, expect to use more paint. These surfaces tend to absorb more products. They produce uneven surfaces, requiring several coatings for a consistent finish.
-
Color Change
Making a color change (particularly from dark to light) can reduce your coverage by half. Lighter colors often struggle to cover darker tones. It means you will need two or more coatings. A tinted primer can help minimize the gap and reduce the number of paint layers required.
-
Primer Usage
Primer is essential to how well your paint performs. A primed surface absorbs paint more evenly. This prevents spots of color and reduces the amount of paint required. Priming is required for all new drywall and previously unpainted surfaces.
-
Paint Quality
High-quality paints usually have a higher pigment content. This means they provide superior coverage with fewer coats. While premium paint costs more, it may save you money by minimizing the amount you use.
Room-by-Room Paint Coverage Guide
Let’s apply how much one gallon of paint covers common areas in your house. While the 300-400 square feet per gallon is a starting point, converting it into actual rooms simplifies planning.
Here’s a quick breakdown:
-
Small Bathroom – 1 gallon
Most bathrooms are less than 100 square feet. One gallon can cover walls and do touch-ups.
-
Average Bedroom – 2 gallons
Bedrooms usually measure 10×10 to 12×12 feet. Two gallons of buffer provides an even coating.
-
Living Room – 2 to 3 gallons
Larger rooms with higher ceilings may require more paint, especially if you are covering dark colors.

How to Calculate Your Paint Needs?
If you want to remove the guesswork, here’s a simple step-by-step formula. It will help you calculate how much paint you will need.
Step-by-Step Wall Paint Calculation:
1. Measure the length and height of each wall.
For example, a 12 ft wide, 8 ft tall wall equals 96 square feet.
2. Multiply the length and height of each wall.
Add up all wall areas to calculate the total square footage.
Example: 4 walls × 96 sq ft = 384 sq ft total.
3. Subtract large openings
Deduct areas for doors, huge windows, and archways.
(One standard door = 20 sq ft, window = 15 sq ft)
4. Factor in coats of paint
Double your total if you need two coats or are making a color change.
5. Divide by coverage per gallon.
Divide the total square footage by 350, which is the average coverage per gallon.
Example: 350 sq ft ÷ 350 = 1 gallon
Tips to Avoid Wasting Paint
Being smart with your paint goes a long way. Knowing how much does one gallon of paint covers can save you money and prevent wasting paint. But following a few additional tips can make your painting job more efficient.
1. Choose the Right Type of Paint
When possible, use a paint and primer mixture. They provide more coverage and decrease the need for multiple coats. It may cost more upfront, but you’ll save in the end.
2. Always Test with a Sample
Before investing in a gallon, test a sample size. This helps you:
- See how the color appears in different lighting.
- Make sure it matches your room.
- Avoid wasting gallons of the “almost right” shade.
3. Store Leftover Paint the Right Way
Do you have any leftover paint? Seal the can tightly and label it with the date. You must keep it in a cool and dry location. Properly kept paint will last for years. You can use it for future touch-ups or accent jobs.
4. Hire a Professional for Precision
Hiring a professional is the best way to avoid wasting paint. Experienced painters can calculate how much paint you’ll need and prevent overspending. They apply paint efficiently, resulting in a clean and even finish.
