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!

Area = Side length x Side length
Length (drop down ft, in, yd, cm, mm, m)
Length (drop down ft, in, yd, cm, mm, m)
Price per unit (drop down ft2, in2, yd2, cm2, mm2, m2)

Understanding the Square footage:

What is Square Footage?

Square footage is a measurement of an area expressed in square feet (unit of measurement). An area is is the size of 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).

How to calculate square footage?

To calculate square footage of an area, you need to measure the width and length of the square area (ft2). The methods may vary depending upon the shape of the area.

For example, to calculate square footage of a room in square or rectangle shape. Simply multiply the length and width of the area.

To calculate square footage of an oddly shaped area, for example an L shaped area. Start by splitting the area into two separate sections making square or rectangle of both sections. Now, measure the area of both sections and add them together to get the total square footage. Before calculating square footage make sure the measurements you have taken are in square feet (ft2). If your measurements are in another unit let’s say inches or meters, you will need to convert those measurements in feet by utilizing the method below.

Also checkout our conversion table below for more unit conversions.

If you have measured the length or width other than feet. Do the following to convert them into feet.

  • – For inches (in to feet): divide the value by 12. Output will be in feet.
  • – For yards (yds to feet): multiply the value by 3. Output will be in feet.
  • – For meters (m to feet): multiply the value by 3.281. Output will be in feet.
  • – For centimeters (cm to feet): multiply the value by 0.03281. Output will be in feet.
  • – For millimeters (mm to feet): multiply the value by 0.00328084. Output will be in feet.

About This Calculator:

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.

We have covered most common use cases. Our calculator allows you to input length and width in many units, such as yards (yds), meters (m), millimeters (mm), centimeters (cm) and inches (in).

It automatically converts your input into feet and also provides output multiple units:

  • – Square Footage (ft2)
  • – Square Yards (yd2)
  • – Square Meters (m2)
  • – Acres (acre)

We also have price or cost input which completely optional but allows you to calculate the cost of materials such as plywood, aluminium, paint and labor cost (Most contractors use price per square foot when calculating their labor cost).

How you can use square footage calculator in your daily life?

Since square footage (sq ft2) is a common unit of measurement. The usage of square footage calculator is also common in our daily life. Specially If you are a hobbyist who likes to work on DIY projects or a professional construction worker or a carpenter. Your projects may include roofing shingles, landscaping for a garden, tiling, flooring space, carpeting and wallpaper. Here we will explain a few real life examples of how square footage calculator can be useful in your next project?

1. How to figure out number of sheets required to sheating wall or roof:

Fоr example, іf you hаvе a wall which is 8 feet high and 40 feet long. The ѕԛuаrе fооtаgе fоr thе wаll can be simply calculated with our square footage calculator. Which is going to be 320 Square feet (sq. ft. or ft2).

Mоѕt ѕhееt gооdѕ are 32 ѕԛuаrе feet. Thе ѕԛuаrе footage оf the wаll is divided by 32.

It wіll take 10 sheets оf рlуwооd or іnѕulаtеd sheathing tо cover thіѕ wаll.

2. How to figure out cost of flooring:

Flооrіng is аlѕо аmоng one of thоѕе things that use thе square foot method tо figure lаbоr аnd materials. This іnсludеѕ сеrаmіс аnd ԛuаrrу tiles, hardwood, laminate, аnd vinyl flooring, аnd саrреtіng. Most соntrасtоrѕ аnd іnѕtаllеrѕ use a price реr square fооt fоr their labor whеn саlсulаtіng thеіr соѕtѕ for іnѕtаllаtіоn.
