Knowing the square footage of your home or a single room is vital if you are trying to sell your home, remodel a room or create a backyard garden. Thankfully, calculating is a rather easy process if you know how to do it correctly. In fact, you can use a nifty little device called a square foot calculator that determines the surface area without having to figure out a math equation.

The process of using a calc to determine square feet is exceptionally easy. For square areas, all a person needs to do is plug in the height and width of the area. One of the most useful things about this calculator is that it allows persons to calculate triangular and circular areas.

## Use below the square footage calculator for any surface

This step is very important, because most people do not know how to calculate square footage for these three shapes. With CalcMonster anyone can determine the area of a space. In addition, by cutting the estimates for circular areas in half, a person can determine the area of curved spaces.

### The Square Footage Formula

In order calculate the sizes of a room you must first measure the width and length of the area. This can be done with a standard tape measure. Once you have these two measurements, simple multiple them together. The received number is the square footage of the room. For example, if the if the length of the room is 11 feet and the width is 18, the square footage of that area would be 198.

If your measuring tape is using inches, you can convert them right away in feet or vice versa.

The square footage formula discussed above works for nearly any area configuration. However, if the room isnâ€™t traditionally square or rectangle shaped, finding the square footage is a tad more difficult. Erratically shaped rooms will need to be split up into even squares or rectangles with one width/height and one length in order to properly determine their square footage. This can be done by simply making invisible lines that separate each section.

Measure the width and length of these invisibly divided sections and then use CalcMonster’s calculator to figure out the square footage of each section. Once have the this information, simply add the square feet of each section together to obtain the total square footage of that area. For example, if the sections of the divided room where 250, 50, 150 and 100, the area would have a total square footage of 550.

#### Calculating the Square Footage of a House with CalcMonster

In order to calculate the square footage of a house, you simply use our formula to find the surface size of each room and area, and then add them together. Figuring square foot will make the entire process go a bit quicker and helps reduce the chance of human error caused by miscalculating the mathematical equation.

When determining the square footage of a house remember that there are no one set of guidelines, and there may be discrepancies in the actually number depending on the person doing the measuring. Some people, for example, will add the enclosed garages or porches. This can make the home seem larger than it actually is.
