## 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 how many pieces of bullnose you will need?

If you have ten feet exposed edge that needs bullnose this is equal to 120″. If you selected a 6″ bullnose or trim piece, you will need to divide 120″ by 6″, which will give you 20 pieces of bullnose needed. Using 8″ decorative liner for the same 120″, you divide 120″ by 8″ which would be 15 pieces of liner needed.

## 4 Tips for Determining Square Footage

Here are few things to consider when preparing to measure the square footage or a property:

**Draw A Floor Plan**. Make a rough sketch of your property's floor plan. This will give you a sense of how you’ll add your calculations for each room together. This is an especially important step if you’re measuring irregularly-sized rooms with a square footage that involve a little more calculation.**Plan which rooms you will be measuring**. When calculating square footage in any home, you should include the measurements of all the rooms in your house that are “finished,” enclosed by four walls, and are heated or cooled. You can measure spaces like garages, basements, or outdoor spaces for your own knowledge, but they should not be included in your square footage calculation.**Take extra care with irregularly-shaped rooms**. All you need to do to measure the square footage of square or rectangular areas is multiply length times width. However many rooms in a home will be more oddly shaped. To determine the square footage of irregular rooms, measure the length of each wall using a measuring tape and record the dimensions on your floor plan. Then divide the shape of your room into regular shapes like squares, triangles, or circles. Calculate the square footage of each separate shape and add them together to get the total square footage of the room.**Remember the stairs**. Include stairs in your home’s square footage calculation if you have them. Multiply the depth and width of one stair, then multiply that number with the number of stairs you have. Some appraisers will include the square footage of stairs twice, as they are considered a part of the floor plan of the floor from which they are descending and the floor to which they are descending. There are no standards governing whether you should include your stairs square footage twice.

## 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).

## 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.

## How to measure the square footage of a house or property

We have touched previously on how to calculate and measure square footage in a simple situation like a rectangular room/house or a circular and triangular… But there are situations in which the shape of the property we want to measure square footage from, is **a bit more complicated** than that. In those cases there are two options: *(1)* using the area of a polygon calculator and other similar calculators by Omni (we can recommend the hexagon / octagon area calculators or *(2)* get creative, as we’re gonna do now.

For **very complicated and irregular shapes**, there is no simple recipe for how to measure the square footage of a house using just one tool. However, we can use a simple trick to achieve the appropriate result. We can try to **decompose the area into several small pieces** that have a regular shape, for which we can calculate square footage. To each of those pieces, we **apply the square footage formula** corresponding to its polygonal shape (different Omni Calculators will prove useful here). If we then **add up the result from every piece**, we will obtain the total square footage of the house, no matter its shape.

There is a chance that the house will have rounded corners of curvy shapes (they are very popular nowadays), and this might seem impossible to do. But in reality, one can get a **very good approximation** using a straight line that goes to the middle of the curved ones or, if we want to be more precise, many small polygons. It could be time-consuming, but it simultaneously can be as accurate as one needs.

## How to calculate the square feet of a house

When preparing to measure the square footage of a home, be it a house, condo, or townhouse, start with a few simple supplies:

- Paper and pencil
- Calculator
- Measuring tape and/or laser measuring tool

If the property is a perfect rectangle, simply measure the length and width and multiply those two numbers together. For example, if your one-story house is 60 feet wide by 40 feet long, then your property is 2,400 square feet (60 x 40 = 2,400).

However, most properties have more complex floor plans. When this is the case, it’s helpful to follow these simple steps to measure square footage.

- Draw a rough sketch of your entire space, labeling all of the rooms you need to measure. Include hallways and vestibules as their own “room.”
- Measure the length and width, in feet, of each room. Then, multiply the length by the width to calculate that room’s square footage. For example: If a bedroom is 12 feet by 20 feet, it is 240 square feet (12 x 20 = 240). For each room, write the total square footage in the corresponding space on your sketch.
- Once each room is measured, add up all the measurements to determine your home’s total square footage.

Note: If you live in a tract home, condo or townhome community, you may be able to get architectural drawings or master builder plans of your floor plan. These may already have your square footage calculated.

## How to convert square meters to square feet?

For example, we might want to know how big a 100 m^{2} (sqm) expressed in sq ft. In other words, we would want to **convert from sq m to sq ft** and find out the square footage of that house, which is:

`100 sqm * 10.764 sq ft/sqm = 1076.391 sq ft`

## 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.

## 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'.

## What is Usable Square Footage?

If you’re involved in commercial real estate in any way, you may have heard the term *“usable square footage”*. **This term describes the total amount of square footage that a tenant is able to use, which excludes areas like hallways, stairwells, and lobbies**. When it comes to residential real estate, the usable square footage in your home refers to the amount of space that would count as your personal space.

Common areas like kitchens, living rooms, hallways, and storage closets wouldn’t count as usable square footage. With this information in hand, you should be able to calculate the actual square footage of your home as well as the usable square footage of your home.

Being able to calculate the square footage of you home can be very helpful when you’re attempting to sell your property or would like to complete a renovation. If you’re getting ready to renovate your entire kitchen, knowing the square footage of the floor will allow you to purchase the right amount of materials. Keep in mind that most flooring materials are priced by square feet.

Let’s say that hardwood flooring has a price of $10 per square foot. If your kitchen has a floor space of 175 square feet, the flooring would likely cost around $1,750. In the event that you work as an architect or structural engineer, knowing how to calculate the square footage of a space can be invaluable for your work.

## FAQS

**How to Calculate Square Footage?**

Square footage is the measurement of an area. The area is the measurement of a two-dimension space bordered by a set of lines. Square footage is mostly used in the calculation for the flooring of the house. To calculate square footage area, it is important to recognize the shape of the plane for example, if it’s a square, rectangle, or any other shape, then the formula for square footage area will be according to the shape. For example, to calculate the square footage of a room in a square (2) or rectangle shape. Simply multiply the length and width of the area. To calculate square footage of an oddly shaped area, for example, an L-shaped area. Start by splitting the area into two separate sections making a square or rectangle of both sections. Now, measure the area of both sections and add them together to get the total square footage. Following are a few examples of how square footage calculators calculate the area for different shapes: 1. Square => Area (ft2) = Side Length x Side Length 2. Rectangle => Area (ft2) = Length x Width 3. Triangle => Area (ft2) = ½ × Base × Height 4. Circle => Area (ft2) = π x (diameter/2)2

**How to Calculate Square Footage of a Room?**

Whenever you plan to buy new flooring, the first thing is to calculate the Square Footage of the room. It’s quite easy to calculate Square Footage, first, you need to measure the square footage of all areas of the room, this includes nooks and crannies and then you need to add all measurements together. This planning takes time and lots of measurements so make sure to double-check your measurements before ordering your flooring. For the safe side, add 5-10% of the waste factor, it is to prevent errors, damages, and extra cuts. To calculate this you need to add a waste factor in square footage like you have 100sqft and you are assuming 5% as a waste factor then 100 × 0.05 = 5 means total sqft will be 100 + 5 = 105sqft.

**How to Calculate Square Footage of a House?**

Whenever you plan to measure the square footage of the house, start with these supplies: 1- Notes, Pencil. 2- Calculator 3- Measuring tool Now it is important to recognize the shape of the house, perfect square, rectangle, or any other shape, then the formula for square footage area will be according to the shape. For example, to calculate the square footage of a room in a square (2) or rectangle shape. Simply multiply the length and width of the area. If you are measuring for a two-story house, simply multiple the square footage by 2.

How to Measure for Wallpapering? First, measure the width (feet) of the wall you plan to add wallpaper. Round the measurement up to the nearest foot. For example, if 14 feet, 9 inches wide, it will be around 15 feet. Then, measure the height (feet) of the wall you plan to add wallpaper. Round the measurement up to the nearest foot. Multiply the rounded width and the height of the wall. This will be your total square footage of the wall. Now measure the width and height of large areas that will not be going to be covered with wallpaper, such as double doors, and round these heights and width. Multiply the width and height of all these areas and sum them up together to get the total square footage of any large area. Subtract the square footage of any large areas from the total square footage of the wall. The result is the total square footage of wallpaper needed to cover the wall.
