How to measure a room

Measuring a room sounds simple, but there are a few key things you need to look out for to make sure you get a floor that fits perfectly. But don't fear! We're here to cover all of the basics for you and help you measure your areas easily.

Follow the steps below

1. Draw a simple diagram of your home

It doesn’t have to be perfect, but the measurements need to be accurate. Just a simple drawing with all the rooms shown is all you need.

Top tip!

If your room is perfectly square or rectangular, the area can be calculated by multiplying the width by the length. For example, a room that is 5m x 2m will need 10m2 of flooring.

2. Chimneys and recesses

If your room includes recesses or chimney breasts, measure the whole space as if they weren’t there, as the flooring will be cut around them.

3. Getting the final figure

Measure each individual area and write the measurement in the relevant space on the diagram. Using these measurements, break the room down into smaller rectangular shapes, calculate their area, and then add them together to figure out the total area of your room.

Top tip!

Add 5% extra to your total to allow for waste.

4. Last checks

Measure your lengths more than once to confirm they’re right – just remember to measure the back of any door frames or room trims.

When it comes to stairs or steps, the process is similar.

Measure the height and depth of each stair to give you the length before multiplying by the width. This will give you the area of each step.


Top tip!

Add 10% for waste and to allow for any margin of error as staircases can be tricky.

Laminate, wood flooring & luxury vinyl tiles


When you buy hard flooring like laminate, wood flooring or luxury vinyl, it’s usually sold in packs that are labelled by their size in meters squared. For example, one pack might include 5m² of laminate flooring. Pay attention to these labels and make sure that you have enough packs to cover the area needed, including wastage.
