8 Important Points for Calculating Square Footage of a House

Knowing how to calculate the square footage of a house is not just useful when buying or selling a property, it's also important when determining property taxes, insurance coverage, and energy efficiency. Whether you're a homeowner, contractor, or prospective buyer, here are 8 key steps to ensure accuracy in your measurements:

• Measure exterior dimensions
• Exclude unfinished spaces
• Consider sloped ceilings
• Include interior walls
• Calculate total area
• Convert to square feet
• Verify measurements
• Consult a professional

With these points in mind, you can accurately determine the square footage of your home. This information is not only essential for practical purposes but also adds value to your property and helps you make informed decisions related to renovations, maintenance, or potential resale.

Exclude unfinished spaces

When calculating the square footage of your home, it's important to exclude unfinished spaces. These areas are typically not considered livable and therefore don't add value to the overall square footage.

• Attics:
  

  Attics are often unfinished and used for storage or as a bonus room. However, they are not counted in the square footage unless they are fully finished and have heating and cooling.

• Basements:
  

  Similar to attics, basements are often unfinished and used for storage or laundry. Again, they are not included in the square footage unless they are fully finished and have heating and cooling.

• Garages:
  

  Garages are typically not included in the square footage of a home, even if they are attached. This is because they are not considered living space.

• Porches and Patios:
  

  Porches and patios are also excluded from the square footage, as they are considered outdoor living spaces.

By excluding unfinished spaces, you will get a more accurate measurement of the livable square footage of your home. This is the area that is used to determine property taxes, insurance rates, and resale value.

Consider sloped ceilings

Sloped ceilings are common in many homes, especially in areas with attics or vaulted ceilings. When calculating the square footage of a room with a sloped ceiling, it's important to consider the following:

• Measure the floor area:
  

  Start by measuring the floor area of the room, as you would in a room with a flat ceiling. This will give you the square footage of the floor space.

• Measure the height of the walls:
  

  Next, measure the height of the walls at their highest point. This will give you the maximum height of the room.

• Calculate the average height:
  

  To get the average height of the room, add the maximum height and the height of the lowest point on the ceiling and divide by two.

• Multiply the floor area by the average height:
  

  Finally, multiply the floor area by the average height to get the square footage of the room with the sloped ceiling.

By using this method, you will get a more accurate measurement of the livable square footage of a room with a sloped ceiling.

Include interior walls

When calculating the square footage of a house, it's important to include the interior walls. This is because the interior walls divide the house into separate rooms and living areas.

• Measure the length and width of each room:
  

  Start by measuring the length and width of each room in your house. Be sure to measure the room from wall to wall, including any closets or built-in cabinets.

• Multiply the length and width to get the square footage of each room:
  

  Once you have the length and width of each room, multiply them together to get the square footage.

• Add the square footage of all the rooms together:
  

  Once you have the square footage of each room, add them all together to get the total square footage of your house.

• Don't forget to include hallways, stairs, and other common areas:
  

  In addition to the rooms, be sure to include the square footage of any hallways, stairs, and other common areas in your house.

By including the interior walls, you will get a more accurate measurement of the livable square footage of your home. This is important for determining property taxes, insurance rates, and resale value.

Calculate total area

Once you have calculated the square footage of each room in your house, it's time to calculate the total area. This is simply the sum of the square footage of all the rooms, plus the square footage of any hallways, stairs, and other common areas.

To calculate the total area, follow these steps:

1. Add the square footage of all the rooms together:
   Start by adding the square footage of each room in your house together. Be sure to include all the rooms, even small ones like closets and bathrooms.
2. Add the square footage of any hallways, stairs, and other common areas:
   Next, add the square footage of any hallways, stairs, and other common areas in your house. These areas are often overlooked, but they can add up to a significant amount of square footage.
3. Add the two numbers together to get the total area:
   Finally, add the square footage of the rooms and the square footage of the common areas together to get the total area of your house.

The total area is an important number to know because it is used to determine property taxes, insurance rates, and resale value.

Here is an example of how to calculate the total area of a house:

• Living room: 200 square feet
• Kitchen: 150 square feet
• Bedroom 1: 120 square feet
• Bedroom 2: 100 square feet
• Bathroom: 50 square feet
• Hallway: 30 square feet
• Total area: 650 square feet

Convert to square feet

If you have measured the area of your house in feet and inches, you will need to convert it to square feet in order to get the total square footage.

To convert feet and inches to square feet, follow these steps:

1. Convert the inches to feet:
   There are 12 inches in a foot. So, to convert inches to feet, divide the number of inches by 12.
2. Add the feet and inches together:
   Once you have converted the inches to feet, add the feet and inches together to get the total number of feet.
3. Multiply the length and width to get the square feet:
   Once you have the total number of feet in the length and width, multiply them together to get the square footage.

For example, if the length of a room is 12 feet 6 inches and the width is 10 feet 3 inches, the total square footage of the room is calculated as follows:

• Convert the inches to feet: 6 inches / 12 = 0.5 feet
• Add the feet and inches together: 12 feet + 0.5 feet = 12.5 feet
• Multiply the length and width to get the square feet: 12.5 feet x 10.25 feet = 128.125 square feet

By following these steps, you can easily convert any measurement in feet and inches to square feet.

Verify measurements

Once you have calculated the square footage of your house, it's important to verify your measurements to ensure they are accurate.

Here are a few tips for verifying your measurements:

• Measure the same area twice:
  The easiest way to verify your measurements is to measure the same area twice. If you get the same measurement both times, you can be confident that it is accurate.
• Use a different measuring tool:
  If you are still unsure about your measurements, try using a different measuring tool. For example, if you used a tape measure the first time, try using a laser measuring tool the second time.
• Have someone else measure the area:
  If you are still not confident in your measurements, ask someone else to measure the area for you. This is a good way to get a second opinion and ensure that your measurements are accurate.

It's also important to verify your measurements if you are planning to make any changes to your house, such as adding a room or renovating a kitchen. Accurate measurements are essential for ensuring that the changes are made correctly.

Here is an example of how to verify your measurements:

• Measure the length and width of a room twice, using a tape measure.
• Use a laser measuring tool to measure the length and width of the room.
• Ask someone else to measure the length and width of the room.

If you get the same measurement all three times, you can be confident that your measurements are accurate.
