One gallon of paint covers approximately 400 square feet. To estimate how much paint your project requires, determine the measurements of the room you plan to paint and round it to the nearest foot. To ensure you will have enough paint, do not worry about excluding areas not to be painted, such as windows and doors. Remember that a 10% waste allowance is automatically added to the total.

Types Of Wall Paint

The first thing you must determine is what kind of wall paint you plan to use for the project. Is this going to be an indoor or outdoor painting project? Depending on where the project will happen, that will determine what kinds of paint you can use. Interior paint includes:

  • Matte
  • Matte Enamel
  • Satin
  • Eggshell
  • Semi-Gloss
  • Gloss

Exterior home paint types include:

  • Primer (not a paint but considered the first layer needed)
  • Latex
  • Enamel
  • Acrylic
  • Oil-Based
  • Water-Based
  • Specialty (anti-mold, anti-mildew, anti-condensation, etc.)

What To Measure For Your Paint Project

Make sure you take measurements of every area you plan to paint before you go out and buy the kind you need or prefer. Some of the common measurements to take include:

  • Wall height (floor to ceiling)
  • Wall perimeter (every wall may vary)
  • Ceiling width and length (if you plan to paint it)
  • Sloping walls form a triangular wall space (see chart below)
  • To determine the area of a triangle, multiply the base length by the height length and then divide by two

                                

Cost To Paint An Interior Room

The cost to paint the inside of your home will be dependent on the number of rooms you want to paint. On average, homeowners throughout the U.S. spend between $1,804 and $2,406 for a professional painting project. The room you choose to paint can influence the price of your project. Your bedroom will cost more to paint than your kitchen due to the amount of wall space that needs to be painted.

Cost To Paint An Interior Ceiling

Painting one’s ceilings is one the most popular professional jobs when it comes to hiring a contractor. This isn’t the easiest DIY project to tackle, even for an experienced DIYer. With the height of this project being the main factor, professionals will have the right equipment to get the job done properly and more importantly, safely. The average cost to paint your ceiling is between $242 and $412. Typically, this is attributed to a 500sf room and takes anywhere from five to six hours to complete.

Cost To Paint Home’s Exterior

A painting project for your home’s exterior will heavily depend on the location of your home, the size of your home and the company you decide to hire. These can drastically change the overall cost of your painting project. Still, it’s nice to have an estimate of the cost. The average cost for a professional painting project on your home’s exterior is between $2,943 and $3,971. This includes the prep work, supplies, labor and paint.

Factors That Influence Your Overall Painting Project Cost

As you may know, painting project costs are dependent on the number of rooms you’d like painted, as well as the paint chosen and the cost of labor. These will influence the overall cost of the project and depending on what you choose, can either increase or decrease the project cost.

If you want to be a little more price conscious about your painting project, there are choices you can make that will decrease your overall painting project cost. Choosing a paint that is more cost-effective will be the main cost factor that will help to decrease your painting cost. There is a big difference between a $45 can of paint and a $10 can of paint. Both the quality and ease of application can be reflected in the price of a can of paint.
