Painting Trim
If you are painting a light-colored room a similar or same color, you often use just one coat of paint.
Each gallon of paint is different, and you should look at specific manufacturers to see their coverage charts. However, in general, each gallon of paint will cover around 350-400 square feet.
How Much Paint Do I Need?
The cost of painting a room is determined by how much paint you need as well as the cost of each gallon of paint. First, we need to calculate. the square footage of the room. This room is 12 x 12 with 8 foot ceilings. This room has 384 square feet (not including windows and doors). If we know that we will use around 2 gallons for two coats in this room. If the average cost of paint is between – a gallon, the cost will be between – 0 for the whole room, depending on the kind of paint we choose.
Example
Paint Coverage by Size
- Quart – 100 square feet
- One Gallon – 350-400 square feet
- Five Gallons – 1750-2000 square feet
Size of the Room or Surface
The amount of paint you need depends on the size of the wall. For example if you wall is 12 wide and 9 feet high, multiply these numbers together to determine the square footage of the entire wall. This would look like this: 12 x 9 = 108 square feet. Therefore, you will need just one gallon for a wall of this size for one coat or two coats of paint.
For example, there are new paint formulations called “one-coat paints“.
- First, measure the distance or perimeter around the room in total feet.
- Next, multiply this number by the height of the walls up to the ceiling.
- Then, calculate the area of the windows and doors and subtract this from the total square footage to get your final number.
We will calculate this number using the previous room example that is 10 x 12 feet to find the amount of paint we need for the trim.
- We are beginning with a room that measures 10 feet on two walls and 12 feet on two walls. If we add 10 + 12 = 22 and then multiply this total number by 2, we get 44 feet.
- Next, we multiply this number by the height of the walls up to the ceiling which is 8 feet high. Therefore, our numbers look like this 44 ft x 8 ft = 352 square feet.
- Then, you need to subtract the square footage from the number of doors and windows you have in the room. We will calculate one door and two windows in this room. The square footage of our door is 21 sq. feet and the two windows are each 15 square feet each (15 sq. ft. x 2 = 30 sq. ft.). We add these together and then subtract 51 square feet from our total square footage. 352 sq. ft.- 51 sq. ft. = 301 square feet.
- Therefore, since a gallon of paint covers around 300-400 square feet, you need one gallon of paint for one coat in this room. If you are painting more than one room the same color, calculate all the square footage together.
We will calculate this number using the previous room example that is 10 x 12 feet to find the amount of paint we need for the trim.
The method you use to apply the paint will determine the amount of paint you will use. For example, using a sprayer for your interior or exterior will use more paint than hand brushing.
- The perimeter of the room is equal to 44 feet.
- Next, we calculate this for our 6 inch baseboard around the room.
- We need to subtract 3 feet for the one door opening in the room. Our equation is 44 ft. – 3 ft.= 41 feet. 41 ft x .5 ft (6 inches) = 20.5 square feet.
- If we have 4 inch crown molding around the room, our calculation looks like this: 44 ft x .3 ft = 13.2 square feet.
- If we add the total square feet of the trim (including the former windows and door), it is 20.5 sq. ft. + 13.2 sq. ft. + 21 sq. ft. + 30 sq. ft. + = 84.7 square feet. One quart, which covers 100 square feet, is enough for the trim in the room.

Painting the Walls
Different surfaces may require more or less paint than others. For example, rough surfaces like concrete or textured walls will need more paint than surfaces that have a glossy finish.
Type of Paint
The actual paint colors you buy affect how much paint you use. For example, if you are changing your room color from a light shade to a dark shade, you need to paint at least two coats of paint in order to get the saturated color that you want.
There are certain kinds of paints that can reduce the number of coats that you use.
Example
In contrast, surfaces that have been painted will not require as much paint. Therefore, the amount you need will be around the amount that you calculate using the hand method or with a paint estimator.
