## Calculating the square footage of a regular rectangular room (Room A):

Steps 1: Measure the length and width inside the room with your tape measure.Step 2: Record your dimensions on a piece of paper.Step 3: We went ahead and used 12ft for our width and 5ft for our length.Step 4: You will take the dimensions and multiple them together (12 x 5) to get your square footage.Step 5: You should get 60 for Room A.

**Room A has 60 square footage.**

This example was very basic and wouldn’t be an ideal 12 foot x 5 foot room. So what do you do if you have 12 feet 3 inches for the width and 10 feet 7 inches for the length?

Steps 1: Measure the length and width inside the room with your tape measure.Step 2: Record your dimensions on a piece of paper.

Step 3: You would round up to the nearest number. For example: the width of 12 feet 3 inches would actually be 13 feet. The length of 10 feet 7 inches will be 11 feet.Step 4: You will take these dimensions and multiple them together (13 x 11) to get your square footage.Step 5: You should get the number 143 for Room B.

**Room B has 143 square footage.**

## How do I figure out square feet from inches?

It might be the case that your room is not built to exact feet. In this case, you may want to calculate in inches instead. This can help you to be more accurate with your measurements. There are 12 inches in a foot. To convert your square footage measurement to inches, simply multiply your measurements by 12. To convert your square inches measurement to feet, divide by 12.

## How to Find the Square Footage of a Room with Many Walls or Many Corners

Determining how to get square footage of a room with multiple walls and corners gets trickier. However, you can break the room down into multiple “boxes” (shapes with 4 corners and 4 sides), multiply the square footage of each box, then add those square footage amounts together.

For example, if you have a room that you’ve separated into 5 distinct rectangles that measure 100, 200, 300, 400, and 500 square feet, your room’s square footage would be a total of 1500 square feet.

## 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.

## How to Calculate Square Footage

Square footage is area expressed in square feet. Likewise, square yardage is area expressed in square yards. Square meters is also a common measure of area.

Assume you have a rectangular area such as a room and, for example, you want to calculate the square footage area for flooring or carpet.

The way to calculate a rectangular area is by measuring the length and width of your area then multiplying those two numbers together to get the area in feet squared (ft^{2}). If you have on oddly shaped area, such as an L-shape, split it into square or rectanglualar sections and treat them as two separate areas. Calculate the area of each section then add them together for your total. If your measurements are in different units, say feet and inches, you can first convert those values to feet, then multiply them together to get the square footage of the area.

### Convert all of your measurements to feet

- If you measured in feet skip to “Calculate the Area as Square Footage”
- If you measured in feet & inches, divide inches by 12 and add that to your feet measure to get total feet
- If you measured in another unit of measure, do the following to convert to feet – inches: divide by 12 and that is your measurement in feet – yards: multiply by 3 and that is your measurement in feet – centimeters: multiply by 0.03281 to convert to feet – meters: multiply by 3.281 to convert to feet

### Calculate the Area as Square Footage

- If you are measuring a square or rectangle area, multiply length times width; Length x Width = Area.
- For other area shapes, see formulas below to calculate Area (ft
^{2}) = Square Footage.

## 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'.

## Calculate the square footage of a room with closets

Some closets are built into the shape of the room. If there are closets in a room which can’t be moved, you will have to install flooring around them. To do this you should split the room into separate areas.

Consider closets and other fixtures which cannot be moved as separate from the floor and measure them individually. Keep a note of the individual measurements of each closet. Next, measure the area of the overall room (width x length). Subtract the measurements of your closets from the overall measurement of the room – this is how to convert room measurements to square feet.

## 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.

## Different Units of Measurement

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

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