How To Calculate Square Feet Of An Apartment: A Definitive Guide
To calculate the square footage of an apartment, simply measure the length and width of each room, multiply them to find the area of each room, and then add all the areas together. This crucial step provides insight into the true size and value of your potential or current living space.
Understanding Apartment Square Footage
Square footage is a fundamental measurement in real estate, representing the total livable area of a property. Knowing how to calculate square feet of an apartment is essential for a variety of reasons, from determining rental costs to planning furniture arrangements. Unfortunately, reported square footage can sometimes be inaccurate, making it important to verify the information yourself.
Benefits of Accurate Square Footage Calculation
Understanding the true size of your apartment offers numerous benefits:
- Budgeting and Affordability: Compare cost per square foot across different apartments.
- Furniture Planning: Ensure furniture fits comfortably within the space.
- Moving Logistics: Estimate moving costs and container sizes.
- Home Improvement Projects: Accurate measurements are crucial for flooring, painting, and remodeling projects.
- Rental Negotiations: Provides leverage when questioning discrepancies or negotiating rent.
The Step-by-Step Process: How To Calculate Square Feet Of An Apartment?
The process of how to calculate square feet of an apartment is straightforward:
- Gather Your Tools: You’ll need a measuring tape (preferably a laser distance measurer for greater accuracy and convenience, especially in large rooms), a notepad, and a pen. A calculator (or your smartphone) will also be necessary.
- Measure Each Room Individually: Start by measuring the length and width of each room. Measure along the floor, ensuring the tape measure is straight. For irregular shapes, break the room down into smaller, rectangular sections.
- Record Your Measurements: Clearly label each measurement in your notepad (e.g., “Living Room Length: 15 feet”, “Living Room Width: 12 feet”).
- Calculate the Area of Each Room: Multiply the length and width of each room to find its area in square feet. For example, a room that is 15 feet long and 12 feet wide has an area of 180 square feet (15 x 12 = 180).
- Account for Irregular Shapes: For rooms with odd shapes, divide them into smaller, more regular shapes (squares, rectangles, triangles). Calculate the area of each of these shapes individually, and then add them together to find the total area of the room. Remember the area of a triangle is 1/2 base height.
- Sum the Areas: Add together the area of each room to determine the total square footage of the apartment.
- Verify and Double-Check: Re-measure each room and recalculate the areas to ensure accuracy.
Common Mistakes to Avoid
While calculating square footage seems simple, several common mistakes can lead to inaccurate results:
- Ignoring Wall Thickness: While not critical for small apartments, for larger units where you’re trying to get very accurate, wall thickness can add up, especially exterior walls. Don’t forget to measure inside the walls.
- Not Accounting for Irregular Shapes: Failing to break down irregularly shaped rooms into smaller sections will lead to inaccurate area calculations.
- Rounding Errors: Rounding measurements prematurely can accumulate and significantly impact the final result. Keep decimal places until the final calculation.
- Inconsistent Units: Make sure all measurements are in the same unit (feet) before multiplying.
- Forgetting Closets and Alcoves: Include all livable areas, even small closets and alcoves.
- Assuming Listed Square Footage is Accurate: Always independently verify the square footage.
What’s Usually Included (and Excluded) in Square Footage Calculations
Understanding what is and is not included in square footage calculations is critical. Generally, the following areas are included:
- Living rooms
- Bedrooms
- Kitchens
- Bathrooms
- Closets (walk-in and standard)
- Finished attics (if accessible and meeting code requirements)
- Hallways
- Interior staircases
The following areas are typically excluded:
- Garages
- Unfinished basements
- Exterior walls
- Porches and patios (unless enclosed and heated/cooled)
- Balconies
- Common areas (hallways, lobbies, etc.)
- Areas with ceilings below a certain height (usually 5 feet).
The specific rules may vary slightly depending on local regulations and the listing agent.
Tools for Calculating Square Footage
While manual measurement remains the most reliable method, various tools can assist you:
| Tool | Description | Advantages | Disadvantages |
|---|---|---|---|
| Measuring Tape | Traditional retractable tape measure. | Inexpensive, readily available. | Can be cumbersome for large rooms, prone to error if not held straight. |
| Laser Distance Measurer | Uses a laser beam to measure distance. | Highly accurate, easy to use, can measure long distances quickly. | More expensive than a tape measure, requires clear line of sight. |
| Smartphone Apps | Various apps use your phone’s camera and augmented reality to measure rooms. | Convenient, readily available, some offer floor plan creation. | Accuracy can vary depending on the app and the quality of your phone’s camera. |
| Online Square Footage Calculators | Websites that calculate square footage based on your input of length and width. | Convenient for quick calculations. | Requires accurate measurements to be input manually. Doesn’t account for irregularities. |
| Professional Floor Plans | Some apartments come with detailed floor plans with square footage calculations already provided. | Accurate, comprehensive. | Not always available. Listed square footage should still be verified. |
Frequently Asked Questions
Is it better to use a laser measurer or a measuring tape?
A laser distance measurer is generally preferable due to its increased accuracy and ease of use, especially in larger apartments. However, a traditional measuring tape is perfectly adequate for smaller spaces, and is also much less expensive.
What do I do if the apartment has angled walls?
For angled walls, break the space down into smaller geometric shapes such as rectangles, squares, and triangles. Calculate the area of each shape individually and then add them together. Remember the area of a triangle is 1/2 base height.
How important is it to include closets in the square footage calculation?
It is important to include closets in the square footage calculation, as they are considered part of the livable space. Failing to include them will result in an underestimation of the apartment’s size.
What if the listed square footage differs from what I calculate?
If the listed square footage differs significantly from your calculation, double-check your measurements first. If the discrepancy persists, discuss it with the landlord or property manager. This information could be useful in rent negotiations.
Does square footage include the thickness of the walls?
Usually, square footage is calculated from the interior walls. However, exterior walls are usually not excluded from the calculation.
How does ceiling height affect square footage?
Ceiling height does not directly affect the square footage calculation, as square footage is a two-dimensional measurement. However, areas with ceilings below a certain height (usually 5 feet) are typically not included in the calculation of usable or “livable” space.
How can I calculate the square footage of a circular room?
To calculate the square footage of a circular room, measure the radius (the distance from the center of the room to the edge). Then use the formula: Area = πr², where π (pi) is approximately 3.14159.
Are balconies included in the square footage of an apartment?
Typically, balconies are not included in the square footage calculation unless they are enclosed and heated/cooled.
Can I rely on the square footage listed in the apartment’s advertisement?
While the advertised square footage can provide a general idea of the apartment’s size, it is always advisable to verify the measurement yourself. Misinformation can often occur, either intentionally or unintentionally.
What is the best way to measure an apartment with irregular shapes?
The best way to measure an apartment with irregular shapes is to divide it into smaller, more regular shapes, such as squares, rectangles, and triangles. Calculate the area of each individual shape and then add them together.
How accurate do my measurements need to be when I calculate square footage?
For most purposes, accuracy within a few inches is sufficient. However, for tasks like flooring installation or furniture purchases, more precise measurements may be necessary.
What does “livable square footage” mean?
“Livable square footage” refers to the portion of the apartment that is suitable for living. This usually excludes unfinished basements, garages, and other areas that are not designed for regular occupancy. Understanding how to calculate square feet of an apartment accurately, especially the livable area, is crucial for making informed decisions about renting or buying.
