When planning to redecorate or trying out a new interior layout, having a room plan drawn to scale is always a good idea.


The secret to drawing a floor plan to scale is just careful when measuring! So let’s learn how to draw a floor plan to scale!



Things You’ll Need

  • Tape measure
  • Notepad
  • Graph paper
  • Pencil
  • Ruler



#1 Measuring the basics

First, before we can draw a floor plan to scale, we need to measure each room that we’re planning to redecorate. Since this could be two rooms or a whole house, measuring will vary with your project.


Measure the length and width of the room in with a tape measure (feet or metres will do, whatever is best for you). Note down the measurements on a notepad.



#2 On graph paper

With our notepad full of measurements, it’s time to transfer these onto graph paper using a pencil and a ruler.


Depending on how you’ve measured and the size of the paper, you can use a square to illustrate either a foot or a metre.


For example, if you have a wall 6 feet long you will have a line from the start point to the end of the 6th square.


Remember that length multiplied by width will give the square feet/metres of the room. This figure is highly useful when ordering paint, wallpaper and flooring.



#3 Measuring features

So we have a nice outline of the room or rooms. So far, so good! Next, it’s time to measure all the doors and windows.


As we’ve used internal measure, so far, you can measure the windows from the inside.


If you have built-in furniture in the room, then it’s good to measure this as we’ll include these features as well.


Now, using the scale we decided on in step 2, we need to convert our measurements into the right scale for our drawing.



#4 Drawing features

Before you rush in and start erasing lines, let’s consider how to best add windows and doors onto our floor plan.



Typically doors are drawn open in the direction they open. For example, if you have to open the door into the bathroom, then it will be shown as such.



As you’ve already drawn solid lines, either draw a box on top or erase part of the line and draw a box in the space. Typically, windows are drawn open, although you might choose to draw bi-fold doors open.


Fitted furniture/other features

Without trying to get too complex, it’s best to stick to simple squares and curved lines as you’re not trying to create an exact masterpiece.


Remember to draw these items to scale and in the correct place.



#5 Create a permanent outline

If you’re happy with your drawing and it’s complete with all major features, then it’s time to create a permanent outline.


Using black ink and a ruler, draw around the wall, doors, windows and other major features. To ensure the best results, make sure you take your time and focus! Dodgy lines will come back to haunt you!


This provides a clear, basic floor plan that is clear and easy to read. Congrats, you’ve learnt how to draw a floor plan to scale!



#6 Make some copies

Make several photocopies of the floor plan so you can try planning the room design in several ways. It’s a good idea to keep the master blank for future use.



#7 Let’s get creative

Measure out the furniture you wish to place in the room. Then get planning, drawing and thinking about your room.


You could also create paper cut-outs of all the furniture, meaning you can easily try out different layouts as you go.
