How to Measure the Square Footage of a House

Knowing how to measure the square footage of a house is essential for various reasons, whether you’re a homeowner, real estate agent, or appraiser. By accurately measuring and calculating the square footage, you can determine the value of a property, plan renovations, or even obtain building permits. Here is a step-by-step guide on how to measure the square footage of a house:

  1. Create a Floor Plan: Start by sketching a floor plan of the house. This will serve as a visual representation of the layout and help you keep track of the measurements.
  2. Measure Room Length and Width: Go room by room and measure the length and width of each space. Use a tape measure to ensure accurate measurements. Record the measurements for each room.
  3. Calculate Room Square Footage: Multiply the length and width of each room to get the square footage of that particular room. For example, if a room measures 10 feet by 12 feet, the square footage would be 120 square feet.
  4. Sum Up the Room Square Footage: Add up the square footage of all the rooms in the house to determine the total square footage. This will give you an overall measurement of the house.

If you have a house with complex shapes or irregular room layouts, there are online square footage calculators available that can help simplify the process. These calculators allow you to input the dimensions of each room and automatically calculate the square footage for you.

It’s worth mentioning that square footage measurements generally include only the finished, heated, and livable areas of the house. Spaces like garages, basements, and attics that are not suitable for everyday living may be excluded from the total square footage.

For a visual representation, here’s an example of how to measure the square footage of a two-bedroom house:

RoomLength (ft)Width (ft)Square Footage (ft²)
Living Room1518270
Kitchen1012120

Remember, accurate square footage measurements are crucial for various real estate purposes. Whether you’re buying, selling, or renovating a house, knowing the exact square footage will help you make informed decisions and ensure fair transactions.

What is Considered Livable Square Footage?

livable square footage

Livable square footage refers to the spaces in a home that can be “lived” in. It includes finished rooms that are heated and cooled, such as bedrooms, bathrooms, living rooms, and kitchens. These are the areas of the house where people spend most of their time and carry out daily activities. Livable square footage provides a practical measure of the usable space within a home and plays a significant role in determining its functionality and value.

When determining livable square footage, certain areas of the house are typically excluded. Unfinished spaces like basements, garages, attics, and storage areas are not considered part of the livable square footage. These spaces may have different uses or may require additional work to make them suitable for everyday living. The focus is on including areas that are finished, accessible, and designed for regular occupancy.

Specific criteria for what is considered livable square footage may vary depending on local regulations and the standards followed by appraisers and real estate professionals. However, the general rule is to exclude areas that are not suitable for everyday living.

In addition to finished rooms, other factors that contribute to livable square footage include ceiling height, natural lighting, and the overall flow and functionality of the space. These factors can impact the livability and desirability of a home, influencing its market value and appeal to potential buyers.

It’s important to note that livable square footage is different from the “gross living area” or “gross floor area.” The gross living area encompasses all enclosed spaces in a home, including finished and unfinished areas. This measurement is often used for building permits, zoning regulations, and overall property assessment.

Key takeaways:

  • Livable square footage includes finished rooms that are heated and cooled, such as bedrooms and bathrooms.
  • Unfinished spaces like basements and garages are typically not considered part of the livable square footage.
  • Specific criteria for livable square footage may vary depending on local regulations and standards.
  • Gross living area includes all enclosed spaces in a home, including both finished and unfinished areas.

Understanding what is considered livable square footage is essential for homeowners, buyers, and real estate professionals. It helps in accurately assessing a property’s value, determining its functionality, and making informed decisions in the real estate market.

Different Standards for Measuring Square Footage

The square footage of a house can be measured using different standards and guidelines. These standards ensure consistency in measuring and reporting the size of properties. Let’s take a look at a few widely recognized measuring square footage standards and guidelines:

National American Standards Institute (ANSI)

The ANSI standard is often used for calculating the square footage of detached single-family homes. According to ANSI, the square footage is determined by adding up the finished square footage of each level of the house. This includes areas with ceilings at least 7 feet high and excludes areas like unfinished basements.

Multiple Service Listings (MLS)

When it comes to determining a home’s primary livable square footage, Multiple Service Listings (MLS) provide essential information. MLS is a database used by real estate professionals, and it typically includes details such as the property’s permitted livable square footage, which is the area suitable for everyday living.

Different Standards for Different Property Types

It’s important to note that different standards may apply to various property types. For example, attached single-family homes or townhouses may have distinct guidelines for measuring square footage compared to detached single-family homes.

Understanding these measuring square footage standards and guidelines is vital to ensure accurate and consistent measurements of the size of properties.

“Consistency in measuring and reporting square footage is crucial for property transactions and ensuring transparency in the real estate industry.”

The Importance of Square Footage in Real Estate

Square footage plays a crucial role in determining the value of a property. When appraising a home, appraisers compare properties of similar size to establish an appraisal price. Accurate square footage measurements are essential for setting the right asking price when selling a home. Additionally, square footage is a key factor in real estate deals involving mortgages, as lenders rely on this information to verify the property’s value.

Knowing the exact square footage of a property helps in gauging its market worth. Appraisers consider the square footage when analyzing the value of a property, as larger spaces typically command higher prices. By evaluating properties of comparable size, appraisers ensure that the estimated values are fair and in line with the market.

“Square footage is like the backbone of a property’s value. It helps appraisers determine the appropriate worth of a home, ensuring that buyers and sellers are working from an accurate estimate.”

When it comes to selling your home, setting the right asking price is crucial. Overestimating the square footage can lead to an inflated asking price, potentially deterring buyers. Conversely, underestimating the square footage can result in undervaluing the property.

In real estate transactions that involve mortgages, lenders rely on accurate square footage measurements to verify the value of the property. This is particularly important as the loan amount is often based on a percentage of the property’s appraised value. Inaccurate or inflated square footage measurements can impact the mortgage approval process and potentially impede the closing of the deal.

Therefore, as a homeowner, it is vital to understand the square footage of your property and ensure accurate measurements. You can refer to the property’s original plans, consult professionals, or even use modern measuring tools that offer reliable results. By having precise square footage information, you can confidently navigate the real estate market and make informed decisions.

What to Exclude from Square Footage Measurements

exclusion from square footage measurements

Measuring the square footage of a house involves considering which areas should be included and which should be excluded. It is essential to exclude spaces that are not considered part of the “gross living area” to ensure accurate measurements. Here are some key factors to consider:

1. Non-Usable Spaces

Non-usable spaces, such as basements and garages, should be excluded from square footage measurements. These areas typically cannot be walked on or lived in, making them ineligible for inclusion in the total square footage of the house.

2. Two-Story Foyers

In some cases, two-story foyers may be considered non-usable spaces and should be excluded from square footage calculations. While visually impressive, these spaces are often open and do not provide functional living areas.

3. Finished Attic Spaces

Finished attic spaces can be included in the total square footage if they meet certain requirements. These requirements may vary depending on local regulations and specifications. It’s important to consult with a real estate agent or appraiser to determine whether the finished attic can be included in the square footage measurements.

Remember that local regulations and industry standards may vary, so it’s crucial to work with professionals who have in-depth knowledge of your specific location. They can provide guidance on which spaces to include and exclude when measuring square footage.

By excluding non-usable spaces and adhering to local guidelines, you can ensure accurate and reliable square footage measurements for your property. This information is valuable for buyers, sellers, and appraisers, as it helps determine the true livable area of a house.

The Statistics of Square Footage

When it comes to understanding the real estate market, knowing the statistics of square footage is essential. Two key factors to consider are the median price per square foot and the average home size. Let’s dive into these numbers:

Median Price per Square Foot

The median price per square foot for a home in the U.S. is $123. However, it’s important to note that this figure can vary depending on the location. Certain regions or cities may have higher or lower median prices per square foot compared to the national average.

Average Home Size

In 2020, the average size of a home in the U.S. was 2,261 square feet. This includes both single-family homes and apartments. However, it’s interesting to see that home sizes have actually been decreasing since 2017. In that year, the median size of a home was 2,426 square feet. This shift in average home size could be attributed to various factors such as changing preferences, sustainability trends, and economic considerations.

To put these numbers into perspective, let’s take a look back at the past. In 1950, the average home size in the country was just 983 square feet. Over time, homes have become larger to meet the evolving needs and lifestyles of homeowners.

Region-Specific Variations

It’s important to remember that these statistics represent national averages. The median price per square foot and average home size can vary significantly from one region to another. Factors such as local housing market conditions, population density, and cost of living may influence these numbers. It’s always recommended to research and consult local market data for accurate and up-to-date information.
