Painting Calculations Made Easy

Painting is a very great way to relieve stress and be creative without being too much specific on the details. Many people love to paint. In houses, painting is one of the basic ways to redecorate and make the home into a more homely atmosphere. The only problem is, especially to painting amateurs, is how much paint we need to use? Well, if you’re into that difficulty. Do not worry because this article will explain to you on how to determine how much paint you will use in painting your household.


If you’re thinking that calculating how much paint you will use is very hard, well think again. Calculating isn’t that hard, neither that easy. The first thing you need to do is to determine the texture of the surface that you will put on paint on. If its smooth, you only need less paint unlike rough surfaces which need more extra coats. Some paint producers put on guidelines on how much paint will be used on different surfaces so better check the can of the paint first before applying.

Now, let’s assume that a can of paint can be used in order to cover at least four hundred square feet on smooth areas while only a hundred fifty or two hundred for rough areas. Let’s go to the calculations. If you’re going to paint on blank walls, measure first the width of the wall by its height then multiply the numbers. Let’s say that your blank wall is at least 20 feet wide and 15 feet high, now we’ll have a 300 square feet of wall to paint on. Smooth surface will only need ½ gallon of paint while textured wall needs about a gallon to cover it.

Well, we have already discussed the blank walls. Now let’s calculate for walls with windows and doors. If you’re mind is thinking that it’s more difficult, well you’re wrong. To calculate how much paint you need, determine the square footage of the window or door by multiplying its width and height. After determining its dimensions, subtract the measurement from the total square footage. Let’s say that the window is about 40 square feet, we need to subtract this from the 300 square footage of the wall and we’ll only have 260 square footage of wall to paint on. You can also do this on non-removable objects like wall-clocks, cabinets and many more.

Remember, don’t waste too much paint. First and foremost, determine what kind of surface you will be painting on. If you’re confused and needs to know more information, you can ask a professional or the paint store employee so that they can give you advices on the paint that you should use. With this, you will be rest assured that you won’t have to waste too much paint on your wall. Have fun painting!
