From Floor to Ceiling—Determine Your House’s Square Footage

You may have heard the phrase “size matters” before, and it’s true when it comes to your home. Knowing the square footage of your house is essential for various reasons, such as selling, renovating, or even just bragging rights. 

However, calculating the size of your home might seem daunting if this is your first time doing it. Fear not, we’re here to help.

This article will provide a step-by-step guide on measuring your home’s square footage, ensuring you get the most out of your living space.

Step 1: Gather Your Tools

Before you begin, you’ll need a few essential tools to make the process smooth and accurate. Here’s what you’ll need:

  1. A tape measure or laser measuring tool: A tape measure is the most common tool for measuring, but a laser measuring tool can provide more accurate results and save time.
  2. A calculator: To help you add and multiply measurements easily.
  3. A pen and paper or a smartphone: To jot down your measurements and calculations.
  4. A floor plan (optional): If you have a floor plan of your home, it can help you keep track of the rooms you’ve measured and provide a visual reference.

Step 2: Measure Each Room

Now that you have your tools, it’s time to start measuring. Follow these steps for each room in your house:

  1. Close all doors and windows to ensure accurate measurements.
  2. Measure the length and width of the room at its longest and widest points. Be sure to include closets, alcoves, and other areas contributing to the room’s size. If you’re using a tape measure, measure from one corner to the other, keeping the tape tight and level. With a laser measure, simply point and shoot.
  3. Write down the measurements for each room, labeling them clearly.
  4. Repeat this process for every room in your home, including hallways and staircases. For stairs, measure the width and the length of the entire staircase (from the top step to the bottom).

Step 3: Calculate the Square Footage

Once you’ve measured each room, you must convert your measurements into square footage. To do this, follow these steps:

  1. Multiply the length by the width of each room. This will give you the square footage for that specific room.
  2. Add the square footage of each room together to get the total square footage for your home.
  3. Remember to include hallways, staircases, and other areas contributing to your home’s size.
  4. If you have a multi-story home, calculate the square footage for each floor separately, then add the totals together to get the overall square footage.

Step 4: Account for Irregular Spaces

If your home has irregularly shaped rooms or areas that aren’t easily measured, you’ll need to adjust your calculations. Here are some tips for dealing with tricky spaces:

  1. Triangular areas: Measure the base and the height of the triangle, then multiply them together and divide by two.
  2. Circular areas: Measure the diameter of the circle, then divide by two to find the radius. Multiply the radius by itself, then multiply the result by 3.14 (pi).
  3. Odd-shaped rooms: Break the room into smaller, more manageable shapes (like rectangles or triangles), measure each section, then calculate and add the square footage of each section together.

Step 5: Double-Check Your Measurements

Accuracy is crucial when calculating square footage, so it’s essential to double-check your measurements. Have someone else verify your numbers or use a different measuring tool to ensure consistency.


Knowing the square footage of your home is essential for various reasons, from selling or renovating to maximizing your living space. 

With these straightforward steps and patience, you can accurately calculate your home’s size and make informed decisions about your property. 

So, grab your measuring tape and get started—you might be surprised by how much space you have to work with!
