Welcome to the ultimate guide on how to calculate square feet! Whether you’re planning a renovation or simply need to measure a room, knowing how to calculate square footage is a crucial skill. In this article, we’ll cover everything you need to know about square footage, from the basics to advanced techniques. So, without further ado, let’s get started!
What is Square Footage?
Before we dive into the nitty-gritty of calculating square footage, let’s first define what it is. Square footage is a measurement of the area covered by a flat surface, such as a floor or a wall. It’s typically measured in square feet, which represents the area of a square that is one foot on each side.
Knowing the square footage of a room is important for a variety of reasons. It can help you determine how much paint or flooring you need for a project, or how much furniture can fit in a space. Additionally, square footage is often used by real estate agents to determine the value of a property.
How to Calculate Square Footage: The Basics
Calculating square footage is a fairly simple process. To find the square footage of a rectangular or square room, all you need to do is measure the length and width of the room in feet, then multiply the two numbers together. The formula looks like this:
| Formula | Example |
|---|---|
| Area = Length x Width | If a room is 10 feet long by 12 feet wide, the square footage would be 120 square feet (10 x 12 = 120). |
If the room is not a perfect rectangle or square, you’ll need to break it up into smaller sections and calculate each section separately. Then, add the square footage of each section together to get the total square footage of the room.
It’s important to note that when measuring for square footage, you should only measure the floor space that is actually usable. For example, if there’s a closet in the room, you wouldn’t include the square footage of the closet in your calculation.
Advanced Techniques for Calculating Square Footage
While the basic formula for calculating square footage is easy to remember, there are some situations where you may need to use more advanced techniques. Here are a few scenarios where you may need to do some additional calculations:
Calculating the Square Footage of Irregularly Shaped Rooms
If the room you’re measuring has an irregular shape, you’ll need to break it up into smaller, simpler shapes in order to calculate the square footage. For example, if the room has a bay window, you would break that area off and calculate it separately. Then, you would add that square footage to the square footage of the rest of the room.
Calculating the Square Footage of a Room with Sloped Ceilings
If you’re measuring the square footage of a room with sloped ceilings, things can get a bit trickier. In this case, you’ll need to measure the height of the room at its tallest point and at its shortest point, and then calculate the average height. Once you have the average height, you can use the basic formula for calculating square footage.
Calculating the Square Footage of a Room with Multiple Levels
If the room you’re measuring has multiple levels, you’ll need to calculate the square footage of each level separately and then add them together.
Frequently Asked Questions
What is the difference between square feet and square meters?
Square feet and square meters are both units of area, but they are used in different parts of the world. In the United States, square feet is the most common unit of measurement, while in many other countries, square meters is used.
How do I convert square feet to square meters?
To convert square feet to square meters, you can use the following conversion factor: 1 square meter = 10.764 square feet. So, to convert 100 square feet to square meters, you would divide 100 by 10.764, which gives you 9.29 square meters.

How do I calculate the square footage of a circular room?
To calculate the square footage of a circular room, you’ll need to measure the diameter of the room (the distance across the widest point of the circle) and then use the following formula: Area = π x (diameter/2)^2.
Can I include the square footage of a closet in my calculation?
When measuring for square footage, you should only measure the floor space that is actually usable. For example, if there’s a closet in the room, you wouldn’t include the square footage of the closet in your calculation.
How do I measure the square footage of a hallway?
To measure the square footage of a hallway, measure the length and width of the hallway in feet, then multiply the two numbers together.
How do I measure the square footage of a room with a diagonal wall?
To measure the square footage of a room with a diagonal wall, you’ll need to measure the length and width of the room along the longest wall, then multiply those two numbers together.
How do I measure the square footage of an L-shaped room?
To measure the square footage of an L-shaped room, you’ll need to break it up into two separate rectangles and measure each one separately. Then, add the two square footages together to get the total square footage of the room.
How do I measure the square footage of a room that is not a perfect rectangle or square?
If the room is not a perfect rectangle or square, you’ll need to break it up into smaller sections and calculate each section separately. Then, add the square footage of each section together to get the total square footage of the room.
How do I measure the square footage of a room with a fireplace?
To measure the square footage of a room with a fireplace, you would calculate the square footage of the room as if the fireplace wasn’t there, and then subtract the square footage of the fireplace.
How do I measure the square footage of an outdoor area?
To measure the square footage of an outdoor area, you would measure the length and width of the space in feet, then multiply the two numbers together.
