How do you accurately measure the square footage of your home before listing it for sale?
Measuring square footage correctly helps you market your home confidently, avoid pricing mistakes, and answer buyers’ questions with accuracy. With a few simple steps—and some smart alternatives if you’d rather not measure yourself—you can make sure your listing reflects the true size of your home.
Why Accurate Square Footage Matters
Square footage is one of the first details buyers and agents look at when comparing properties. If your home is listed with incorrect measurements, it can:
- Misrepresent your property’s value (overpricing or underpricing)
- Lead to appraisal or financing issues
- Cause confusion or even legal disputes after the sale
Getting this number right sets the stage for a smoother transaction.
How Accurate Square Footage Can Impact Your Property Taxes
In Indiana, your property tax bill is partly based on the assessed value of your home. That assessment relies on accurate details—especially square footage. If your home’s recorded size is larger than it really is, you could be overpaying in property taxes each year.
By double-checking your home’s measurements, you may uncover errors in the county records. If you do, you can file an appeal with your local assessor’s office and request a correction. This process typically involves:
- Providing proof of your home’s actual square footage (such as measurements, floor plans, or an appraisal).
- Submitting the evidence along with your appeal.
- Waiting for the assessor to review and adjust your home’s assessed value.
Even small discrepancies in square footage can add up over time, so accurate measurements not only help you sell your home with confidence but may also help you save money on property taxes.
Tools You’ll Need
Before you start, gather these basics:
- Tape measure (or laser measure for efficiency)
- Graph paper or notepad
- Calculator
- Pencil and ruler
Pro tip: Sketch each floor’s layout as you go to keep track of your numbers.

Step 1: Measure the Exterior for Simplicity
The most straightforward way to calculate square footage is by measuring the exterior walls. For a rectangular or square home:
- Measure the length and width of the house from the outside.
- Multiply length × width to get the square footage.
Example: A house that’s 40 feet long and 30 feet wide = 1,200 square feet.
Step 2: Account for Multiple Stories
If your home has more than one level:
- Measure each floor separately.
- Use the same length × width formula.
- Add the totals together.
For example, if both your first and second floors are 1,200 square feet, your total = 2,400 square feet.
Step 3: Handling Odd Shapes and Layouts
Not every home is a simple rectangle. If your home has angles, extensions, or bay areas:
- Break the floorplan into smaller shapes (rectangles, triangles, or circles).
- Measure each shape individually.
- Add them together for the total square footage.
This method ensures every nook and cranny is included.
Step 4: What to Exclude
Keep in mind, not every space counts toward square footage:
- Unfinished basements
- Garages
- Attics that don’t meet ceiling height standards
Generally, only finished, heated, livable spaces are included.
Alternatives to Measuring It Yourself
If you’d prefer not to take the measurements on your own, you have options:
- Hire a professional appraiser: They’ll provide an official, certified measurement.
- Work with a real estate photographer: Many offer floor plan services with square footage included.
- Ask your REALTOR®: Professionals like us at The Haibrid Group often have resources to help sellers verify measurements before listing. Email us at ListWithHaibrid@gmail.com for a list of certified measurers in your area.
