Anyone with their first interior home painting project has stood in the paint aisle wondering how many cans they need to bring home.

To keep your colors matching and avoid return trips to the store, do some calculations ahead of time:

Measure The Length And Height Of Your Window Trim

Last on the list is window trim. My office has one window. First I measured the length and width of the trim.

So the total perimeter of my window trim is 60+60+48+48 = 216

216 / 12 = 18 feet.

The trim on my window is quite thin, at just 1. Again, convert this to feet. 1 inch / 12 = .083.

18*.083 = 1.5 square feet for window trim

This is a negligible amount of square footage. But your trim may be different. So its important to do all your measurements!

You will also have to consider the texture of the walls. Highly textured walls may require special equipment to paint. Otherwise, you risk messing up the entire process. Plus, its important to consider the overall condition of the walls. Painters may have to patch holes, repair drywall, and remove wallpaper, which will further drive up your projects cost.

    Best Interior Paint Colors

    Estimating the Amount Of Paint Needed For Interior Surfaces

    Color is always the first consideration when painting a home. Most paint manufacturers offer samples, so you can make a more informed decision before you start painting. Because light within a room may vary from wall to wall and from day to night, try painting a large piece of poster board in the color or colors you are considering. Move the board from wall to wall and look at it for a minimum of 24 hours at a time in each space to make sure you like the color before committing.

    Keep in mind that color impacts the way a room appears in many ways. Light colors may help brighten a darker space. Cool colors will recede visually from the eye and make a small space appear bigger. Warm colors contract visually, making larger spaces appear smaller or cozier. By combining cool and warm tones in one room, like with accent walls, you can visually change the shape of a room, making rectangles look more like squares. There are plenty of different combinations you can play around with to suit your space.
