How to Figure Out Square Footage
To calculate square footage accurately, follow these key steps:
- Measure Length and Width
- Multiply Length by Width
- Convert to Square Feet/Meters
- Add Room Areas Together
- Exclude Non-Living Spaces
- Consider Irregular Shapes
- Use Digital Tools (Optional)
- Consult a Professional (if needed)
Remember, precise measurements and attention to detail are crucial for accurate square footage calculations. If you're unsure about any step or dealing with complex layouts, don't hesitate to seek professional assistance.
Measure Length and Width
To calculate square footage, we need to determine the length and width of the space. Here's how to do it:
- Use the Right Tools:
Grab a measuring tape, laser distance measurer, or any accurate measuring device. Ensure it's in good working condition and displays measurements in the desired unit (feet/inches or meters).
- Start with Length:
Identify the longest side of the room or space you want to measure. This is typically the length. Stand at one end of the space, extend the measuring tape or laser measure to the opposite end, and note down the measurement.
- Measure the Width:
Now, find the widest part of the space perpendicular to the length. Position yourself at one side of the space, extend the measuring tape or laser measure to the opposite side, and record the measurement. Make sure you measure at the widest point to capture the maximum width.
- Accuracy is Key:
Take your measurements carefully, ensuring the measuring tape or laser measure is straight and aligned with the edges of the space. Avoid guesstimating or rounding off measurements, as even small errors can affect the final square footage calculation.
Once you have the length and width measurements, you're ready to move on to the next step: multiplying them together to determine the square footage.
Multiply Length by Width
Now that we have the length and width measurements, it's time to multiply them together to determine the square footage of the space.
Step 1: Set Up the Multiplication:
Write down the length and width measurements you obtained in the previous step. Make sure they're in the same unit of measurement (feet/inches or meters).
Step 2: Multiply the Numbers:
Multiply the length by the width. If you're using feet and inches, multiply the feet measurements first, and then multiply the inches measurements. For metric measurements, simply multiply the length and width values.
Step 3: Understand the Result:
The result of the multiplication is the square footage of the space. It represents the total area of the two-dimensional surface within the length and width boundaries.
Example:
Let's say you measured a room to be 12 feet long and 8 feet wide. To calculate the square footage:
1. Multiply 12 feet by 8 feet: 12 x 8 = 96
2. The result is 96 square feet, which represents the area of the room.
Remember, square footage is a measure of area, not volume. It doesn't take into account the height of the space. If you need to calculate the volume of a room, you'll need to multiply the square footage by the height.
Once you've calculated the square footage of each room, you can add them together to determine the total square footage of your house, apartment, or any other enclosed space. This information is crucial for various purposes, including property valuation, renovation planning, and taxation.
Convert to Square Feet/Meters
Depending on your location and preference, you may need to convert your measurements to square feet or square meters. Here's how to do it:
- Square Feet to Square Meters:
To convert square feet to square meters, multiply the square footage by 0.092903. For example, if you have a room that's 100 square feet, multiply 100 by 0.092903 to get approximately 9.29 square meters.
- Square Meters to Square Feet:
To convert square meters to square feet, multiply the square meter value by 10.7639. For example, if you have a room that's 10 square meters, multiply 10 by 10.7639 to get approximately 107.64 square feet.
- Use a Conversion Calculator:
If you don't want to do the math yourself, you can use an online square footage converter or a calculator app on your phone. Simply enter the value you want to convert and select the appropriate units.
- Be Consistent with Units:
It's important to use the same unit of measurement throughout your calculations. If you start with feet and inches, convert everything to square feet before proceeding with further calculations. Similarly, if you start with meters, convert everything to square meters.
Accurately converting between square feet and square meters ensures that your square footage calculations are consistent and reliable. This is especially important when dealing with international property transactions or when comparing properties in different countries.
Add Room Areas Together
Once you've calculated the square footage of each room, it's time to add them together to determine the total square footage of your house, apartment, or any other enclosed space.
Step 1: List Room Square Footage:
Make a list of all the rooms in your space, along with their respective square footage. You can create a simple table or spreadsheet to keep track of this information.
Step 2: Add the Square Footage:
Starting from the first room on your list, add its square footage to the square footage of the next room. Continue adding the square footage of each room until you've included all the rooms in your space.
Step 3: Calculate the Total:
The final sum of all the room square footage values is the total square footage of your space. This represents the total area of the enclosed space, excluding non-living areas like garages, porches, and balconies.
Example:
Let's say you have a house with the following room square footage:
- Living Room: 200 square feet
- Kitchen: 150 square feet
- Bedroom 1: 120 square feet
- Bedroom 2: 100 square feet
- Bathroom: 50 square feet
To calculate the total square footage, add these values together:
200 + 150 + 120 + 100 + 50 = 620 square feet
Therefore, the total square footage of the house is 620 square feet.
Knowing the total square footage of your space is essential for various purposes, such as determining property value, calculating construction costs, and planning renovations. It also helps you compare properties accurately when buying or selling real estate.
Exclude Non-Living Spaces
When calculating the square footage of a house or apartment, it's important to exclude non-living spaces. These spaces are typically not considered part of the habitable area and may have different tax implications or valuation methods.
- Garages:
Garages are primarily used for parking vehicles and storage. They are not considered living spaces and should be excluded from the square footage calculation.
- Porches and Patios:
Porches, patios, and decks are outdoor living spaces that are not enclosed. While they may be used for recreation or relaxation, they are not counted in the square footage calculation.
- Balconies:
Similar to porches and patios, balconies are also outdoor spaces that are not enclosed. They are typically attached to upper-level rooms and are not included in the square footage calculation.
- Basements and Attics:
Basements and attics are often unfinished or used for storage. While they may be converted into living spaces, they are typically not included in the square footage calculation unless they meet certain building codes and regulations.
By excluding non-living spaces, you can accurately determine the habitable square footage of your property. This is important for various purposes, such as property valuation, taxation, and insurance. It also helps potential buyers or renters understand the actual living space available to them.
Consider Irregular Shapes
Many rooms and spaces have irregular shapes, which can make calculating square footage more challenging. Here's how to handle irregular shapes:
Step 1: Divide the Space into Shapes:
Break down the irregular shape into smaller, regular shapes such as rectangles, triangles, or trapezoids. This will make it easier to calculate the area of each individual shape.
Step 2: Calculate the Area of Each Shape:
Use the appropriate formulas to calculate the area of each regular shape. For example, to calculate the area of a rectangle, multiply the length by the width. To calculate the area of a triangle, multiply the base by the height and divide by 2.
Step 3: Add the Areas Together:
Once you have calculated the area of each individual shape, add them together to get the total area of the irregular space. This represents the square footage of the irregular-shaped room or space.
Example:
Let's say you have a room with an irregular shape, consisting of a rectangle and a triangle. The rectangle measures 12 feet long and 8 feet wide, while the triangle has a base of 6 feet and a height of 5 feet.
1. Calculate the area of the rectangle: 12 feet x 8 feet = 96 square feet
2. Calculate the area of the triangle: (6 feet x 5 feet) / 2 = 15 square feet
3. Add the areas together: 96 square feet + 15 square feet = 111 square feet
Therefore, the square footage of the irregular-shaped room is 111 square feet.
By breaking down irregular shapes into smaller, regular shapes, you can accurately calculate the square footage of any space. This is particularly useful for rooms with bay windows, angled walls, or other unique architectural features.
