Remember, the input can only be in feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m) but never a combination of two different units!

To understand how to calculate square footage we must first begin with the definition of area. An area is the size of a two-dimensional surface. The area of a square is the space contained within a set of lines. These lines should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m).

**The formula:**Area of a Square= Side length x Side length

**Answer** = (Length x Width) square area

**Abbreviations of unit area: ** ft2, in2, yd2, cm2, mm2, m2

**Where do you need it in daily life?**

Our Square Footage Calculator / SQFT calculator helps you calculate the area required for roofing shingles, landscaping for a garden, tiling, flooring space, carpeting and wallpaper. There is even a Siding Square Footage Calculator so you can estimate House Siding costs without any hassle.

**How to Calculate Square Footage?**

Square Footage is the term that expresses the area of any space in square feet measurements. You may be confused about how to calculate the square footage of any space. Well don’t worry, it is not much difficult as you think. Here we are going to describe the process of calculating the accurate area of any space in square feet measurements.

Suppose you have a rectangular space of which you want to calculate the area in square feet. First, you need to measure the length and width of your room and then, you have to multiply these numbers. The result will be feet squared (ft2) of your room.

Now let suppose you have the oddly shaped area like L-shaped, you simply split this shape into two sections making a square or rectangular shape of both sections and treat them as two different areas. Now, measure the area of both sections and add them together to get the total square footage.

Make sure that your values are in feet. If they are in different units, then first convert them to feet and then multiply them together to get the appropriate square footage of the area.

**What measurements do you need?**

You need to know the length and the width of the area you wish to measure in either feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) or metres (m).

**What can you calculate with this tool?**

You can calculate the area in square feet, in square inches, square yards, square centimetres, square millimetres and square meters. Yes, it is that awesome.

Our calculator gives you the option of calculating the exact cost of materials. All you have to do is enter the price per unit area and voila, you have the total cost of materials in a single click!
