What is square footage?

Square footage is a way to describe an area that is measured in square feet. It is often used when describing an apartment, office or commercial space. When looking at real estate listings, many homes and apartments are often sold based on their square footage. Many contractors also use square footage measurements as well as landscapers to help determine how much material is needed for each project. Square foot calculations have been around for hundreds of years and have become one of the most common ways to measure area.

What are square feet?

A square foot is a measurement of area. It’s most often used in real estate and property transactions, but can be applied to anything. The measurement is simply one foot on each side. So a square yard would be measured as a three-foot by three-foot space (1 x 1), a nine-square yard plot would measure 3 x 3, or 9 ft. squared and so on.

How do you calculate square feet?

The most accurate way to calculate a space’s square footage is by using a laser or tape measure, then multiplying it by itself. But let’s face it: We aren’t all professional contractors. Most people don’t have access to either tool, and while they might be handy on building sites, they aren’t something you can carry around with you every day.

Should I use an imperial or metric calculator?

Square footage can be a tricky measurement to calculate. In most parts of Canada, there are metric calculations based on 10 x 12 meters per one-square meter, but in America and some European countries, all measurements are based on feet and inches. When you’re trying to decide which calculator you should use to accurately measure square footage, consider your property location; if it’s in North America or Western Europe, imperial will likely work better.
