If you’re gearing up to paint a bedroom, living room, or home office, one of the first questions you’ll probably ask is:
How much paint do I actually need?

It’s a smart question, and the good news is that you don’t have to overthink it. With a few simple guidelines, you can get the right amount of paint without overspending or running out halfway through the job.

Start with the Walls

For the average-sized room, two gallons of paint is usually just right. One gallon of paint covers about 350 square feet, and most standard bedrooms fall somewhere between 300 and 400 square feet of wall space.

So if you’re painting all four walls, two gallons should cover it, even if your room has higher ceilings or a bit of extra surface area.

Don’t Forget the Ceiling

Planning to paint the ceiling too? You’ll need an additional gallon of ceiling paint. Ceilings are often overlooked, but giving them a fresh coat can make the entire room feel brighter and cleaner.

Just make sure to use flat or matte ceiling paint to reduce light reflection and hide imperfections.

What About Trim and Doors?

If you’re also painting the baseboards, trim, and doors, add one more gallon to your shopping list. Trim paint typically goes farther than wall paint, but it also requires more precision and often needs two coats for full coverage—especially if you’re going from dark to light or vice versa.

For most bedrooms or small living rooms, this 2-1-1 combo (2 gallons for walls, 1 gallon for ceiling, 1 gallon for trim and doors) will give you enough paint to cover everything.

Quick Recap: What You Need

• 2 gallons for the walls
• 1 gallon for the ceiling
• 1 gallon for trim and doors

With this amount, you should have more than enough to complete a full bedroom or a small living room without running back to the store.
