How to Calculate Area for Wood Flooring

Calculating How Much Wood Flooring You Need

One of the first questions our team will ask when it comes to ordering or giving you a quote for your wood flooring is how much area in square metres (m2) that it needs to cover. Measuring and working this out is straightforward but we thought it would be worth going over the method to make it quick and easy for you, and to give you total confidence that it’s correct. So, how should you measure and calculate the square meterage for your wood flooring?

Measuring Your Floor Area in Square Metres

Using an example, let’s look at how to measure and calculate the square meterage of flooring you will need for your project.

You will need:

  • a pen or pencil
  • paper
  • a measuring tape
  • a mobile phone or calculator
  • a ruler (if you want to be neat)

Make a rough plan of your room on your paper — a simple line drawing of the four walls around you is fine. Just make it big enough to write in the measurements you’re about to take.

Floor Area of Square and Rectangular Rooms

For simple rooms that are rectangular or square in shape, simply measure the maximum length and width of your room from wall to wall, and measure right into any doorways. Remember to include any alcoves, closets and other additional areas that you’d like your flooring to cover.

Where walls are not totally straight, always measure across at the widest point. We recommend measuring from wall to wall (not from the skirting). Even though the skirting will be covering an an expansion gap, it’s best to use the total floor area going right up to the wall.

An Example: Calculate the Area of a Rectangular Room

Let’s imagine we want to order some beautiful new wood flooring for a rectangular room that is 6 metres long and 4 metres wide. Simply multiply length by width, e.g., 6 x 4 — to get your floor area of 24m2.

Then, all you need to do is add a percentage of additional material (wastage) onto that figure to get the total area you will need.

Adding Wastage Factor to Your Measured Area

Once you have your square meterage for the area, add a wastage factor of 10% to the total. It’s simple: multiply the square meterage you’ve calculated by 1.1.

So, using the above example, to calculate the total area plus the wastage (based on standard 10% wastage) to your 24m2, just multiply your area by 1.1, e.g. 24 x 1.1 = 26.4m2.

Please note: if the room is more irregular in shape and there are lots of corners, alcoves, and difficult angles, you will need to make extra cuts to fit your wood flooring. This will inevitably cause more wastage. So, generally it’s wise to up the wastage factor for more awkward shaped rooms and where flooring is going to be scribed to stone walls etc.

With parquet flooring such as Herringbone, we recommend 15% wastage (multiply area by 1.15 in this case). Find out more about wastage in this guide.

Floor Area of L-shaped and Irregular-shaped Rooms

To make things easy, split the room into sections e.g. rectangles or squares, and using the same principals as above, calculate the square meterage of these sections. Then, simply add the square meterage together for each space to get your total area.

In this example, we’ve split this room into two sections and calculated that one is 24m2 and the other is 15m2, giving a total area of 39m2.

For more unusual shaped rooms, just split the room into sections using the simplest shapes you can, and add it all up.

Don’t Forget to Add Your Wastage to the Area

Once you’ve calculated the floor area, you’ll just need to add on the appropriate wastage, then you should know exactly how much flooring you need to order for your space.

Using Mobile Apps to Measure Your Space

You could also take advantage of the latest room-mapping tech with some of the great new apps available on iOS and Android that are designed to help with this process, such as RoomScan Pro and MagicPlan. If you’re not confident in using these and trying it out for the first time, we’d suggest double-checking using manual methods just to make sure you get it right.
