How To Make a Floor Plan: To Scale

Creating a floor plan to scale is a game-changer when it comes to designing and arranging a space. Whether you're planning a new layout, rearranging furniture, or just getting a better feel for your room’s dimensions, mapping it out properly will save you a ton of time and effort. Here’s how to do it step by step.

Step 1: Start with a Rough Sketch

Before you even think about scale, grab a piece of paper and make a rough sketch of your room. This doesn’t have to be perfect—it’s just a guide to help you take accurate measurements.

Here are the key measurements to note:

  • The perimeter of your walls

  • The dimensions of your doors and windows

  • Any architectural details or built-in furniture

  • The sizes of your existing furniture pieces (if you plan to include them in your layout)

Once you’ve got those measurements jotted down, your rough sketch should look something like this:

Step 2: Transfer to Scale Using Graph Paper

Now, it’s time to make it official! Grab some graph paper because we’re going to transfer your rough sketch into a properly scaled floor plan.

To keep things simple, let’s set our scale: One box = 6 inches in real life.

For example, if your wall measures 13 feet, here’s how you plot it:

  • Double the feet count (since each foot contains two 6-inch segments): 13 feet → 26 boxes

If your window wall is 11 feet 8 inches:

  • 11 feet = 22 boxes

  • 8 inches is just over one extra box, so round up slightly to 23 boxes (with a touch of a 24th box for accuracy)

Step 3: Add Doors and Windows

Now, let’s position doors and windows precisely.

  • Say the distance from the left wall to the start of your pocket door is 6 feet 3 inches. That translates to:

    • 6 feet = 12 boxes

    • 3 inches = half a box

  • If on the other side, the measurement is 4 feet 1 inch, that would be:

    • 4 feet = 8 boxes

    • 1 inch = just a touch into the next box

Now that everything is positioned correctly, your to-scale floor plan should resemble this:

Step 4: Add Furniture to Scale

Here’s where the magic happens! Using the same scale (1 box = 6 inches), sketch out your furniture pieces, cut them out, and move them around on your floor plan.

By doing this, you can:

  • Experiment with different layouts

  • Ensure there’s enough walking space

  • Avoid placement mistakes before moving heavy furniture

For example, I quickly realized that centering the bed on this wall wouldn’t work—there wouldn’t be enough walking space to access the bathroom. By shifting things around, I could find a layout that worked without cramping the room.

Why This Method Works

This technique is a lifesaver because it allows you to visualize your space accurately. You can see what your current furniture fits, what doesn’t, and even test new furniture sizes before making a purchase. No more guessing if that new couch will be too big—it’s all planned out beforehand!

Give this method a try next time you're rearranging a room—it’ll make your life so much easier!
