How To Calculate Square Footage

Calculating the square footage of a room is simple

Calculating the square footage of a room is simple and straightforward. All you need to do is multiply the length and width of the area by feet. If a room is 10 feet long and 15 feet wide, the area will consist of 150 square feet in space. The basic formula for this calculation is:

Length x width = area in sq. ft.

It’s important that you make this calculation in feet as opposed to inches. However, this formula can also be used to translate square footage into square yards or inches depending on what you want to measure. Keep in mind that calculating the square footage of a room isn’t always as easy as it might seem at first glance. If your room is perfectly square or rectangle, you should be able to perform this measurement without issue. On the other hand, the presence of any nooks, crannies or oddly shaped corners could add some difficult-to-parse elements to the equation.

If you would like to translate a room’s square footage into square inches, your first step would involve the above calculation. Both the width and the length should be separately multiplied by 12, which is the number of inches in a foot. After you obtain this measurement, you should multiply the two numbers together, which would result in the total square inches of a room. A 150 square-foot room would measure at 21,600 square inches.

If you happen to work with fabrics, you will likely need to know how to translate measurements into square yards. Follow the simple equation mentioned above before dividing both numbers by three. The numbers should then be multiplied. If a room is measured at 300 square feet, it could also be measured at 33.3 square yards.

It’s also possible to measure a room in square meters. To begin, look at the formula above. The width and length of the area should be separately divided by 0.3. These two numbers will then need to be multiplied together to obtain the correct calculation. A room that’s measured at 150 square feet will also be measured at 13.93 square meters. The following sections take a look at what you need to do to perform square footage calculations in different types of rooms.

Calculating the Square Footage with Closets

Certain closets are built directly into a room’s shape, which can make it easier for you to determine the square footage of the entire space. If you’re unable to move the closets in your room, the flooring will need to be installed around your closets. Even though your calculations will take longer to complete, the easiest way to perform these calculations is by dividing your room into separate areas. Your closets should be separate from your room floor.

You should then calculate the square footage of each closet on its own. The final calculation depends on the size of your closet. Some larger walk-in closets that are made for two people can be 10 feet long and 8 feet wide, which would result in the closet having a space of 80 square feet. On the other hand, smaller apartment closets may only have spaces that measure at 15-20 square feet.

Once you’ve measured each closet in a given room, you should then measure the area of the floor outside of your closets. After you’ve arrived at this number, you can determine the total square footage of your room by adding the square footage of your closets to the square footage of the room itself. However, it’s important to understand that larger closets are sometimes considered to be separate from the room when calculating square footage. In this situation, all you would need to do is subtract your closet measurements from the total room measurements.

Calculating the Square Footage of an Oddly Shaped

Calculating the Square Footage of an Oddly Shaped Room

If your room has a more complex shape to it because of numerous nooks and crannies, arriving at the actual square footage of the space could be very challenging if you don’t have professional assistance. Many homeowners make the mistake of attempting to calculate the square footage of an oddly shaped room with a single formula.

In reality, it’s much easier to identify the square footage of your room by dividing the room into even shapes of rectangles or squares. You can then measure each individual shape by multiplying the length and width of the shape. Every multiplication you make can be added together to achieve the total square footage of a room.

If you’re attempting to purchase enough materials for a new floor in your oddly shaped room, it’s highly recommended that you consider waste. During almost any renovation or remodeling project, some materials will be damaged from extra cuts that need to be made, errors, or accidents.

Whatever the reason, you can mitigate this issue by increasing your total square footage by 10% when purchasing materials. If the area that’s set to receive new flooring is 200 square feet in size, you should consider adding 20 square feet to the materials you purchase. You never want to be in a situation where you run out of the materials you need during the middle of a project. This could result in project delays and a dissatisfied property owner.

If all else fails and you don’t believe that your square footage calculations are accurate, you may want to hire a professional. When you hire a reputable contractor who has performed numerous flooring installations over the years, they will almost certainly be able to help you measure the square footage of the area you want to renovate. While you can call a professional to help you with calculations for any room, it’s highly recommended that you consider this option when attempting to determine the square footage of an oddly shaped room.

How to calculate square footage? 

It’s easy.  Follow these steps.

Measure the length in feet, Measure the width in feet. Multiply the length figure by the width figure.  This will be your total square footage for that portion of your project.  Continue to repeat this for all parts of the space that will get the same tile.   Add these together for your total square footage.

Measuring in inches works as well.  Do the math the same way, then divide by 144 to get your total in square feet. When calculating square footage account for the entire space (i.e. under vanity/cabinets).

How to measure square footage of a room

It is very easy to compute square footage of a room of standard widths/lengths. All you need to do is multiply the length of the room by the width of the room. From example, if a room is 10 feet wide and 15 feet long, you would multiply 10 x 15. This would mean you would require 150 square feet of flooring to renovate the room.

How to Calculate the Square Feet of a Home or Residence

When measuring the square footage of a home or residence, some special considerations apply to determine the inhabitable square footage. The livable size of a home helps determine the market value and price and helps buyers understand the overall size.

Only livable rooms, with finished walls, floor, and ceiling, count toward the finished area of the home. For a room to be considered livable, the space should be finished and should have heating or air conditioning as applicable.

Indoor spaces count toward the square footage of a home, while outdoor spaces typically do not. In fact, the American National Standards Institute has defined rules[1] for what counts as finished area and which rooms contribute to the gross living area of a home.[2]

To calculate the total area, measure each room in feet using a tape measure. Then, multiply the length and width of each room to get the square footage, then add them all together.

The calculator above can help determine the square feet of each room, then simply add all the room’s areas together. We also have great resources on how to measure rooms and complex spaces.

How to Calculate Price per Sq Ft

To calculate the price per square foot of your home, divide the total price by the number of square feet.

price per ft2 = total price ÷ total ft2

For example, to find the price per ft2 of a home that costs $200,000 and is 2,000 ft2 use this formula.

price per ft2 = $200,000 ÷ 2,000 ft2 price per ft2 = $100

If you’d prefer not to do the math, you can also use our unit price calculator to calculate the price per square foot.

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.

How to find the square footage of a circle

  1. Measure the diameter of your circle in feet.
  2. Divide your diameter by 2 and then square it (multiply it by itself).
  3. Multiply your total by π (3.14159265)
 The formula for calculating the area of a circle

The formula for calculating the area of a circle is: π r2 (with r being the radius of the circle, which is half the diameter). π is the symbol for pi (3.14159265).

 

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.  

Why Tenants, Homeowners, and Landlords Need to Know Square Footage

There are several reasons why tenants, homeowners, and landlords should all know how to calculate square feet:

  • Knowing the square footage of a room can help you confirm if your furniture will fit.
  • Knowing the square footage of a specific surface can help you estimate renovation costs. If you’re replacing a kitchen countertop, for example, you need to calculate the square footage of the countertop so you can get accurate quotes for the cost of the job.
  • When you know how to calculate square feet, you can make sure you order the right amount of supplies and materials. If, for example, you plan to paint a wall that’s 12 feet long by 10 feet tall, you need to find the total square footage so you know how much paint to buy.
  • Perhaps most importantly, knowing the square footage of homes and apartments helps you compare prices to find the best value. Let’s say you’re deciding between two similar apartments: Apartment A is $1,500 per month and Apartment B is $1,800 per month. Which is the better deal? Well, it depends on the square footage. If Apartment A is 500 square feet and Apartment B is 1,000 square feet, you’re getting more space for your money with Apartment B.
