Why Measure Square Footage?
Homeowners should measure square footage to get an accurate assessment of their property’s size. The most obvious reason homeowners will need this information is for a property value estimation when they sell their house. The square footage will directly influence the purchase price, and it could make a big difference when marketing the property.
Even if you are not selling your home, it can still be helpful to measure square footage. Some cities will require homeowners to disclose this information when applying for renovation or building permits. Square footage can also be helpful in the event your property value assessment comes out too high. In these cases, homeowners will want to accurately re-measure their homes’ square footage to get their property taxes lowered.

Convert among square inch, square foot, square yard and square meter
You could, for example, perform all of your measurements in inches or centimeters, calculate area in square inches or square centimeters then convert your final answer to the unit you need such as square feet or square meters.
To convert among square feet, yards and meters use the following conversion factors. For other units use our calculator for area conversions.

How to measure for bullnose?
Measure the length of any outside edge where your tile edge would be exposed or you want framed out. Bullnose (also called trim pieces and decorative tiles) are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6″ bullnose, 8″ decorative liner), then the rule is: Your total linear length divided by the length of each piece equals your quantity needed.
Ask The Pros
Learning how to calculate the square feet of a house can be a challenging task. Thankfully, there are experts to help you. It is common practice to hire a professional appraiser to accurately measure your home. Depending on the property’s size, the cost of an appraiser to measure the square footage can range from $100 to several hundred dollars. When an appraiser calculates the square feet of a house, they also only include areas that are heated and cooled. While two different appraisers will sometimes have different measurements on square footage, there is usually only a 1-3% variance. Appraisers will do their best to calculate square footage with scientific accuracy.
How to find the square footage of a triangle
- Measure the length of the base and the height of the triangle in feet.
- Multiply your base and height measurements together.
- Divide your total by two to get the square footage of the triangle
The formula for calculating the square footage area of a triangle is: base × height / 2. To work out your cost of materials, simply multiply this figure by your 'price per square foot'.

How many square feet is a 12×12 room?
The square footage of a room measuring 12 feet wide by 12 feet long is 144 square feet. To calculate this you simply multiply the width by the height. 12ft × 12ft = 144 sq ft.
What to leave out
A good rule of thumb to ensure you’re taking proper measurements is to exclude space you can’t walk on or live in. These types of spaces do not count as “gross living area.”
“Someone might think, ‘If I get the measurement of my first floor and I have a two-story house, I just multiply that by two,’” Day says. However, if that first floor includes a two-story foyer, you can’t count the non-usable space.
Basements and garages, even if they are finished, don’t generally count toward total square footage. Basements are typically excluded because they are built below grade, meaning below ground level. If your state does allow basements to be included in the total square footage of a home, though, you’ll likely need an ingress and egress, or a safe way to enter and exit the basement to the outside.
Finished attic spaces — with some regulations, including ceiling heights — can count toward the total square footage of your home. If you are planning to sell your home, work with a real estate agent to craft a listing that accurately reflects your property.
Why Is Square Footage Important?
Square footage is important in real estate because it is the clearest representation of the total area of livable space in a homeowner's property. Here is an overview of the practical reasons that square footage is important.
- 1. Home value: Square footage is one of the variables factored into setting the listing price or determining the fair market value of a house. If you order an appraisal for your new house to determine its fair market value, the appraiser will factor the square footage of this house to similarly-sized homes in the area.
- 2. Securing a mortgage: Most mortgage lenders will require homebuyers to get a home appraisal before granting them a loan to protect the lender from promising more money than the house is worth. If your appraiser finds that a home is worth less than it is listed for—potentially because of a square footage discrepancy—the buyer may not get a loan for the house unless the listing price is adjusted to affect the appraisal value.
- 3. Property taxes: Assessing your home and measuring the square footage can help gauge whether a homeowner is paying too little or too much in property taxes. Your property’s square footage directly impacts the assessed value of the house, which influences property taxes you’re required to pay.
Determining the Size of Area
Step 1: Inspect the Area
The first piece of information you need to know is the shape and dimensions of your lawn, particularly the width and length. You will want to measure and multiply the area length times the width in feet until the square footage is 1,000 sq. ft. and mark off this area with the help of a marking tool like washable paint or objects to distinguish the treatment areas border line.
Step 2: Convert Measurements
If your yard is rectangular or square, measure the length and width then multiply together (length X width = square footage). For example, if your yard has a length of 10 feet and width of 8 feet, you would multiply 10 by 8 to get 80 square feet.
Be aware for triangle shaped lawns, you will measure the length and width, multiply together, then divide by two ( length X width / 2 = square footage).
If your lawn is a not a perfect rectangle, break the lawn into different sections to measure more easily, then add measurements together to get the area’s total square footage.
For treatment areas with flowerbeds and other obstructions in the yard you will measure the square footage of the object and subtract from your yards total square footage.
Example, you have a property that is 12,000 sq. ft. and in the middle you have a landscape bed with a length of 3 feet and width of 2 feet. You will multiply 3 by 2 to get 6 feet, then subtract from your yard total.
- 3 ft. X 2 ft. = 6 sq. ft.
- 12,000 sq. ft. – 6 sq. ft. = 11,994 sq. ft.
Therefore, you will treat an area with 11,994 sq. ft.
Measuring for Schluter Profile Edging
Measure the length of any outside edge where your tile edge would be exposed. Not all edging is the same. Speak to your design associate about different uses.
