How to Calculate Square Feet of a House: A Simple Guide

Understanding the square footage of your home is essential whether you are purchasing, selling, or renovating. The size of a property is important for assessing its value, aiding in renovation plans, and is frequently needed for tax purposes. Measuring the square footage of your house can be easy with some assistance, even if you're doing it alone.

This tutorial will guide you in determining the square footage of a house, covering terminology, tools, and calculations.

1. Why Square Footage Matters

The value of a property is determined by its square footage, impacting taxes, utility bills, and pricing in the real estate market. Real estate agents utilize square footage in order to determine the price per square foot, which enables buyers to assess whether they are receiving a reasonable offer. Square footage is valuable for planning renovations because several contractors determine their pricing based on the project area's dimensions.

2. Key Terms to Know Before Measuring

Before diving into the calculations, familiarize yourself with these basic terms:

• Square Footage: The total area of a house or room measured in square feet.

• Gross Living Area (GLA): Includes all habitable spaces (bedrooms, bathrooms, living rooms) but excludes garages, basements, and outdoor areas.
• Usable vs. Rentable Square Footage: Common in commercial properties, but worth knowing if your home includes shared spaces.

Having a clear understanding of these terms will make measuring and calculating square footage easier.

3. Tools You’ll Need for Measuring Square Footage

Gathering the right tools ensures that your measurements are accurate and easy to perform. Here’s what you’ll need:

• Tape Measure or Laser Measure: A standard tape measure works well for small rooms, but a laser measure can speed up the process for larger spaces.

• Calculator: You’ll need this to add up the square footage of each room.
• Graph Paper: Optional but useful for sketching out floor plans and organizing room measurements.

Once you have your tools, you’re ready to begin measuring.

4. Steps to Calculate Square Footage Room-by-Room

Now, let’s look at the steps to calculate the square footage of a house by measuring each room and adding up the total.

Step 1: Draw a Floor Plan (Optional)

Start by sketching a rough floor plan of your house, breaking it down into rooms. This doesn’t need to be precise but will help you organize your measurements and make the final calculations easier.

Step 2: Measure Each Room’s Length and Width

• Measure the length and width of each room in feet.
• If a room has an irregular shape, break it into smaller sections, measure each section separately, and then add up the area of each section for the total square footage.

For example, if a room is 15 feet long and 10 feet wide, multiply 15 by 10, giving you 150 square feet.

Step 3: Calculate Square Footage of Each Room

For rectangular or square rooms, multiply the length by the width:

Room Area=Length×Width\text{Room Area} = \text{Length} \times \text{Width}Room Area=Length×Width

Write down the square footage of each room for easy reference.

Step 4: Calculate Square Footage of Odd-Shaped Rooms

For irregular spaces, try breaking the area into simpler shapes, such as rectangles and triangles. Calculate the area for each shape, then add them together for the room’s total square footage.

For example:

• A triangular area can be calculated as:
  Triangle Area=12×Base×Height\text{Triangle Area} = \frac{1}{2} \times \text{Base} \times \text{Height}Triangle Area=21​×Base×Height

Add the area of each section to get the total for that room.

Step 5: Add Up All Room Areas

Once you have the square footage for each room, simply add them together to get the total square footage for your house.

5. Calculating Square Footage for Different Areas

Some areas of the house are excluded or included differently in square footage calculations:

• Living Areas: Bedrooms, living rooms, and kitchens count toward square footage.

• Basements: Generally excluded unless finished and accessible from the main floor.
• Garages and Attics: Excluded unless finished as living space.
• Outdoor Spaces: Decks, patios, and similar areas don’t count unless enclosed and climate-controlled.

Knowing which areas to include is key, especially if you’re preparing a measurement for tax or appraisal purposes.

6. Common Mistakes to Avoid When Calculating Square Footage

Even with the right tools, it’s easy to make small errors that impact accuracy. Here are some common mistakes and how to avoid them:

• Overlooking Closets and Hallways: These areas are often included in the GLA and can add up, so remember to measure them.

• Rounding Too Soon: Rounding each measurement before calculating the total can lead to a less accurate total. Try rounding only after adding up all measurements.
• Not Accounting for Irregular Spaces: Skipping irregular spaces or estimating them roughly can reduce accuracy. Take time to measure and calculate these areas carefully.

7. Practical Example: Calculating Square Footage for a Home

Let’s say you’re measuring a house with the following rooms:

• Living Room: 15 ft x 20 ft = 300 sq ft

• Kitchen: 10 ft x 12 ft = 120 sq ft
• Bedroom 1: 12 ft x 12 ft = 144 sq ft
• Bedroom 2: 12 ft x 14 ft = 168 sq ft
• Bathroom: 8 ft x 10 ft = 80 sq ft
• Hallways/Closets: 40 sq ft

Total Square Footage Calculation:

300+120+144+168+80+40=852 sq ft300 + 120 + 144 + 168 + 80 + 40 = 852 \text{ sq ft}300+120+144+168+80+40=852 sq ft

This total of 852 sq ft would be the calculated square footage of the house.

8. Using Online Calculators and Professional Assistance

While measuring on your own is possible, some homeowners prefer using online calculators or even consulting a professional appraiser for more complex spaces. Many real estate websites offer square footage calculators where you can enter room dimensions to get an instant total. Professionals can provide a more detailed measurement, including areas like finished basements, that might be excluded or included differently based on location.
