So you’ll have to paint 328 square feet in this instance, one gallon of paint will be sufficient to fill the walls with one coat of paint.

How Many Doors Can a Quart of Paint Cover?

A quart of paint should be enough to completely cover a door frame. In actuality, just under half a quart of paint will coat a 20-square-foot door in two layers if you use two coats of primer first. The amount of paint you’ll need will increase if you don’t use a primer. A 20-square-foot door requires around 400 mL of paint to be painted twice.

How to Calculate How Much Paint is Needed?

Determine how much paint you’ll need by following the steps outlined in the following section. To make it easier, we’ve included an instance: A 15 by 15-foot space with a 7-foot ceiling height is available. The room is equipped with a door and two windows.

Step 1: Get the Total Perimeter

Take a total length (perimeter) all around the room and note it. (15 ft. +15 ft.) times 2 = 60 ft.

Step 2: Multiply the Perimeter by the Floor-to-Ceiling Height

To calculate the overall wall area, multiply the perimeter by the elevation of the ceiling: 60 ft. by 7 ft. is 420 sq ft. 

Step 3: Determine the Door and Window Area

Doors are typically 21 sq ft. in size: 

21 sq ft. x 1 door = 21 sq ft.

A typical window is 20 sq ft. in size: 

20 sq ft. x 2 = 40 sq ft.

Step 4: Compute the Total Coverage Area

To determine the surface area of the wall to be painted, subtract the entire wall area by the number of doors and windows on the wall. 

Formula: Wall area – door area – window area = total coverage area

420 sq. ft. – 21 sq. ft. – 40 sq. ft. = 359 sq. ft. 

Step 5: Know How Much Paint is Needed

As a general guideline, a gallon of high-quality paint will generally cover 400 sq ft of surface area. A quart will coat a surface area of 100 square feet. So you’ll need to paint 328 square feet in this scenario, a gallon of paint would be sufficient to cover the walls with one layer of paint.

For instance, the density of the paint and the amount of pressure with which you administer the paint are important considerations. A factor to consider is the smoothness of the area, as a greater quantity of texture demands additional paint to be applied to it.


Using a pint, you can coat approximately 50 sq ft of surface area. That will be enough for a feature wall or a backdrop wall. A pint may be plenty to coat a wall as long as it is up to 7 ft wide if you have a 9 ft ceiling but there is little room for mistakes. Comparable to this, a pint of paint may be adequate to cover the ceiling of a smaller space. Furthermore, it may be suitable for a single or two furniture pieces.

Half Pint

Paint in a half-pint container can cover an area of up to 25 sq ft. In most cases, that is not sufficient to completely cover a conventional wall in a house or apartment. In the case of an 8-foot ceiling, you would be limited to a stretch of approximately 3 feet wide by using that paint can size, as an illustration.

The same half-pint may be enough to cover one modest-sized furnishings or the baseboard and cabinetry in a tiny bedroom, depending on the situation. It might also be used for minor projects such as wall nooks or crevices – because they do not take up the entire wall surface – or other similar modest projects.

Color selection for a room involves harmonizing the architectural characteristics of the room in relation to other parts of the house and producing a constant flow all through the area. Because so much of our life takes place within the framework of our houses, it’s no surprise that we treat the color of the walls significantly.

Hazard Chemicals

Paint, no matter what it is comprised of, is a complex mixture of thousands of different ingredients. Because it’s been scientifically designed to glide effortlessly over your walls and surfaces, it will harden once it has been exposed to air. When you stop to think about it, that must be a complicated recipe. 

In addition, the very first time you smell home paint, you realize there is something not very appetizing going on. Despite the fact that we have progressed a lot from the traditional lead-paint puns, not all paint is fully harmless.

Using the dimensions, you may determine your budget limit. After you’ve put money aside for supplies such as paintbrushes, rollers, and drop towels, you can determine how much you’re prepared to splurge on paint.

Amount of Light

Far more than paint, lighting has the ability to completely modify a room or environment. Throughout the day, the light wanders about, throwing shadows and reflecting off the walls at distinct viewpoints. We think about the impact of sunlight on our antiquities, wall paintings, and couches, but we don’t always contemplate the impact of daylight on the actual walls too.

Use of Space

If you’re working on an interior room, the initial thing to consider is how you’ll make use of the available space. This should be noted that the type of paint you choose ought to be your initial consideration since it might limit the color scheme you can utilize. It’s best to cut down your search as often as possible until your eyes begin to cross from the sheer number of color tests you’ll be glancing at during the process.
