how to find square feet of a room

Whether you're a renter, homeowner, or real estate investor, knowing how to calculate square feet is a handy skill to main. Properly calculating square footage can save you lot from making big mistakes when moving to a new flat, renovating a dwelling, or buying real estate. And it'southward not that difficult to acquire!

In this article, we'll:

Ascertain square footage,
Explain why it'south important to know how to calculate square feet, and
Detail exactly how to calculate square anxiety (fifty-fifty in oddly-shaped rooms).

Here is everything you need to know near how to calculate square feet.

What is Square Footage?

Square footage is simply a convenient way to measure out the expanse of any surface. In homes and apartments, square footage is most normally used to tell yous how much floor infinite you have to piece of work with. You lot might come across an advertizing for an apartment promoting 700 square anxiety of usable space, for example. Or maybe you lot run into a home listing with a 50 square foot balustrade. Square feet are besides used to calculate areas like wall infinite and counter space.

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 assistance you ostend if your furniture will fit.
Knowing the foursquare footage of a specific surface tin can assist y'all judge renovation costs. If you lot're replacing a kitchen countertop, for example, you demand to calculate the square footage of the countertop and so y'all can get accurate quotes for the cost of the job.
When yous know how to calculate foursquare feet, you can make sure y'all lodge the right amount of supplies and materials. If, for example, you plan to pigment a wall that's 12 feet long by 10 feet alpine, yous need to find the total foursquare footage so you know how much paint to buy.
Perhaps about importantly, knowing the foursquare footage of homes and apartments helps you compare prices to discover the best value. Permit's say you lot're deciding between ii like apartments: Flat A is $one,500 per month and Apartment B is $ane,800 per month. Which is the better bargain? Well, it depends on the square footage. If Apartment A is 500 square feet and Apartment B is 1,000 square feet, yous're getting more space for your money with Apartment B.

How to Calculate Foursquare Footage

You can calculate the foursquare footage of a standard-shaped room (a square or rectangle) in three piece of cake steps:

Measure the length of the room with a record measure.
Measure the width of the room.
Multiply the length times the width.

Example: If the room is 8 feet long and 10 feet broad, the foursquare footage of the room is fourscore square feet (8 x 10 = eighty).

But what if you demand to measure out the foursquare footage of a whole apartment or firm? No trouble! You have ii options:

Option one: Measure the length and width of the whole business firm and multiply them together (this works best for perfectly rectangular homes).
Option 2: Calculate the foursquare footage of each private room, then add those numbers together (this works best for homes with lots of angles).

Different Units of Measurement

Using square feet is the nigh common unit of measurement in American real estate. But it's not your only option. For small projects, y'all might want to work in foursquare inches. For big projects, like landscaping, square yards might make more sense. And in international real estate markets, square meters are the standard for abode measurements.

Whatever your unit of measurement, the formula is the same. Multiply the length times the width to summate the area of square and rectangular surfaces. Simply make sure yous're using the same unit of measurement of measurement for your length and width. If yous're looking for foursquare anxiety, measure both distances in feet; if you're looking for square meters, measure both distances in meters.

How to Summate Square Footage of Abnormally-Shaped Rooms

Calculating the square footage of abnormally-shaped rooms requires a bit of high school geometry. Instead of a simple length-times-width, y'all'll need a slightly more complicated formula.

Round

The formula for finding the expanse of a circle is 𝜋r². This ways yous accept pi times the radius of the circle squared. So to mensurate the square footage of a round space, you lot demand to mensurate the widest part of the room (the bore), divide that number in half (to get the radius), multiply the radius times itself, then multiply that by iii.1416 (pi).

Example: If the widest part of the room is 12 anxiety, the radius is 6 feet, and so the square footage of the room is 113.ane square feet (iii.1416 ten 6 ten vi = 113.1).

Triangular

The formula for finding the area of a triangle is ½b h. This means you lot take half of the altitude of the triangle's base times the triangle's height. So to measure the square footage of a triangular space, y'all need to measure the base of the room, divide that number in half, and so multiply it by the distance from the base to the far corner.

Example: If the base of operations of the room is 10 feet, and the distance from the base to the far corner is 12 feet, the square footage of the room is lx square anxiety (½ x x ten 12 = 60).

Other Odd Shapes

You tin can observe the square footage of any odd shape using a combination of the calculations for rectangles, circles, and triangles. For instance, you might have a room thatwould be a rectangle, if it weren't for a triangular alcove. In that instance, you lot can calculate the expanse of the rectangular role of the room, calculate the surface area of the triangular alcove, and add them together.

Similarly, yous might take a perfectly rectangular bedroom, just in that location'southward a square chunk of information technology taken upwardly by a walk-in cupboard. Simply calculate the square footage of the rectangle, then summate the square footage of the closet, and decrease the closet space from the full area.

Yep, calculating area can get tricky when you take odd shapes, but it'due south well worth your time to learn how to summate square feet. Y'all'll be a more informed consumer, you'll be able to more accurately estimate costs of materials for home projects, and y'all'll be able to properly compare real estate deals based on relevant price per square human foot metrics.
