How To Measure Square Feet
Most home projects involving flooring require you to know the square footage of your space. Prior to hiring a local floor installation to redo your floors, measure the space that the professional will be working with and ask for a material or labor project quote.
To measure square footage, you’ll need the following.
 100foot tape measure
 Basic calculator
 Pen or pencil
 Notepad, printable measurement worksheet and/or a copy of your home’s floor plan
Step 1: Sketch and Divide Each Room into Shapes
 Print out our measurement worksheet, or make a copy of your home’s floor plan (if you need to measure the entire space).
 Sketch the shape of the room. If your room is an irregular shape, divide the room into simple shapes.
Most rooms can be broken down into rectangular shapes, so it’s easy to calculate the area. However, irregular spaces like circular dining rooms or triangular closets can prove to be more difficult. Our calculators above can help you streamline these calculations.
Step 2: Measure the Room to Calculate Square Footage
Measure the length, width, or radius of the different shapes you’ve sketched in inches. This helps you avoid adding fractions and compound numbers. Keep your measurements in their simplest form, and always round up to the nearest inch. Use a notepad or our printable sheet above to jot down the measurements in inches as you measure each room of the house.
Step 3: Convert Inches To Feet and Calculate Square Footage
 Divide your measurements in inches by 12, which will convert your measurements into feet.
 Then, use our square footage calculator to find the area of your space’s shape. If you’ve divided a room into multiple shapes, remember to add up all of the shapes’ areas to find the room’s total area. Using our calculator’s “Add the new shape” button, you can easily input measurements for different shapes and calculate total area.

How To Calculate Square Footage of a House for Appraisal
For real estate advertisements and listings, most agents determine square footage by measuring the house’s exterior dimensions. To calculate in this way, measure cornertocorner or endtoend of your home exterior. Then, take the exterior length and multiply by the width.
Real estate agents often measure straight cornertocorner to find the total area. They then deduct nonheated spaces and add heated spaces whose footprints exceed the endtoend measurement. This process can get complicated. If you’re selling your home, you’ll probably need a measurement from a certified appraiser. These are the instances when hiring a house appraiser near you is the best option.
It’s particularly useful to hire someone familiar with the local rules and standards for these calculations and valuing other aspects of a home. As objective as the process is supposed to be, these factors impact the final value the home appraiser reaches.

What Counts as Square Footage
Square footage generally refers to the parts of a house that have finished flooring, walls, ceilings and the ability to live in yearround. The inclusion of some areas into your total can only be considered on a casebycase basis, such as finished basements*. Before you take out your measuring tape, keep this in mind:
Areas that almost always count towards square footage:
 All indoor rooms*
 Stairways
 Closet areas
 Livable attics (if the area has at least seven feet of clearance)
Areas that don’t usually count:
 Dens
 Garages
 Pool houses
 Porches
 Patios or courtyards
 Unfinished basements*
*Keep in mind: A basement must meet specific criteria to add it to a home’s total square footage — it must be finished to the same quality standards as the rest of the house.
Typically, the American National Standards Institute (ANSI) sets the standard on what counts as square footage in a home, but the guidelines aren’t always enforced. Plus, multiple listing services (MLS) guidelines across the U.S. have different rules on reporting. What counts as finished square footage depending on various local factors.
FAQs
When measuring square footage for tile, how much overage should you account for?
Account for 10% of overage when calculating the total area of a space. Simply multiply the total measurement by 1.1 to determine how much overage you need. Finally, add your overage to the total area. That will be the approximate amount of flooring or wall tiles you need to order.
When calculating how much tile a project requires, be sure to check out our tile calculator.
When measuring square footage for carpeting, how much overage should you account for?
After calculating your square footage, add 10% of overage to your carpet order for cutting, waste and staggering the carpet joints. For example, let’s say you have a 10 by 10 room, which is 100 square feet. When considering the cost of carpet installation, order 10% more for a total of 110 square footage of carpet to account for overage.
For convenience, check out our userfriendly carpet calculator.
What qualifies as a “finished” indoor space when calculating square feet?
Depending on your state, different indoor spaces qualify as “finished”. For example, in most cases, a finished garage or detached pool house won’t count towards the square footage of a home. However, these spaces are usually listed separately. Keep in mind that your basement must have flooring or carpeting and an HVAC system to qualify as a “finished” basement.
How do I calculate the square footage of my kitchen?
Approach calculating the size of your kitchen the same way you’d approach any other room. Be sure to measure the length and width of each bay window, alcove or offset. Remember, your counter space, cabinetry, walkin pantry and kitchen island are included in the square footage of your kitchen.

Bill, the article I just read said you include bay windows if they are supported by foundation. Window seats would not be counted.

I have a load of hand made flooring. I would like to us it in a large room, but not sure if I have enough. The boards run 3.5 inches by anything from 5 inches to 6 feet. I don’t remember how to figure the square footage on this. I know the room is 245 sq. ft.
I was doing the (example here) 3.5″ x 46.625″=163.1875 NOW how do I get it to square feet or foot and inches?
Thanx for the help! 
Tom E, October 27:
When calculating sq in to sq ft divide the sq in by 144 to get sq ft.
A sq foot is 12in by 12in or 144 sq in.
So your 1 board example is 1.133 sq foot.
to find out the entire room add up all the sq in then divide by 144 to give you the total sq ft. Don’t forget to allow for waste, deduct 10 to 20%.(Video) Increase Your Property Value using Square Footage?!?

I need to know if I have 52 feet – how many square feet is that ?

Jim Dasher, May 29:
@Frank, Oct. 19: Main House: 73′ x 42’= 3,066′ x 2 (2nd level) = 6,123′.
Add: HVAC Porch: 150′. (Your ‘breezeway’ does not count as living space.)If your garage is 2story, and 30′ x 30′ per each level and the top level is your ‘guest room’, add: 900′. (NOTE: ‘Garage areas’ are NOT living space! Guest rooms are.)
RECAP:
Main House: ……… 6,123 sq. ft. (if two story)
HVAC Porch: ………… 150 sq. ft.
Garage ‘guest room’: 900 sq. ft. (If second floor of garage)Total square footage based on ‘your’ information: 7,173 sq. ft.

Veronica, August 25:
What is the square footage for a room that is 13’X 14′ in size?

John, September 29:
Does the footprint of exterior & interior walls count? The footprint of a walk in fridge? Is the footprint of a stairway plus the footprint of an under stairway storage area add up as two separate entities or Is the footprint of the vertical column measured singularly. I understand garages even if finished don’t count, but do storage closets accessible only via the garage count? If an attic is otherwise finished but not commonly accessible (e.g. via a pull down attic ladder) does it’s area officially contribute to the home’s square footage? Does an elevator’s footprint contribute to a home’s official square footage? I’ve (tried) to read various building codes but only end up more confused.

John, September 29:
Addendum… Other areas I’m curious about is if walk in pantries, kitchen island area, and the footprints created by counter space & cabinetry, etc. add to a home’s official square footage.

Allen Garrison, December 15:
They only count livable space in the square footage of the inside.
