6 Things to Know to Measure Square Footage

Here’s a helpful guide on all things related to measuring square footage for home sellers.

What is the Average Square Footage of Single-Family Homes?

For reference, the average square footage of a single-family home in the United States is 1,650 square feet.

However, where you live could impact the average square footage in your area. The number of bedrooms you have will also alter the overall square footage of your property. For example, one-bedroom homes are typically around 900 square feet, while a four-bedroom home is usually 2,400 square feet.

What Exactly is Square Footage?

To measure square footage, you have to calculate the total area of all of the finished rooms in your home. Essentially, you take the length and width of your rooms and multiply them to find the area, which equals the square footage of your home.

Let’s say you have a rectangular room that is ten feet by eight feet. The square footage would be ten times eight, which is eighty square feet.

The calculation to measure square footage is simple. Simply calculate the square footage of each room, and add them together.

Let’s say your small one-bedroom home has the following room measurements:

  • Living Room: 8’ x 9’ = 72 sq. ft.
  • Bathroom: 4’ x 4’ = 16 sq. ft.
  • Kitchen: 10’ x 10’ = 100 sq. ft.
  • Dining Room: 8’ x 10’ = 80 sq ft.
  • Bedroom: 11’ x 11’ = 121 sq. ft.

Then, your total square footage would equal the sum of all of the room’s square footage added together. That totals 389 square feet.

What Rooms Are Included in Square Feet?

The main rooms of your home will likely all be included in your square foot calculations, such as the:

  • Living room
  • Dining room
  • Bedrooms
  • Bathrooms
  • Family rooms
  • Finished basements
  • Finished attics
  • Kitchens

Rooms That Aren’t Usually Included When You Measure Square Footage

Not every area and room on your property is included in the square footage calculation of your home.

To know what to include — and what not to include — when you add up the square footage of the rooms in your house, there’s a general rule that can guide you.

In most cases, any room that is unfinished or does not include heating and cooling should not be included. Another indicator that a room will not be included in the square foot calculation is if it can only be accessed from a part of your home that falls under the two categories above: unfinished and no heating and cooling units.
