Measuring For Flooring – Our Top Tips & Tricks

Measuring Made Easy!

There are many things to consider when installing new flooring, from finding the right products to colour and pattern matching, skirting and underlay. Measuring the floor to ensure you order the correct quantities should be the easy part!

However, we often receive worried emails from customer uncertain in their measurements, risking making time consuming and costly mistakes. Therefore, we have created this handy guide and list of useful tips for you to follow, helping to make the process run as smoothly as possible!

To create a seamless and professional finish, there are some key tips and tricks to follow.



Using a tape measure and calculator will help you achieve the most accurate results. We always recommend buying 5 – 10% extra flooring. This will allow for cut offs and for the best layout of planks. For complex spaces that require cutting planks down to size, this is good practice, allowing for greater wastage then you may need for a simple space.

Basic Room Measurement

At the most basic level, the area of a room dictates the amount of flooring required. This is simply calculated by multiplying the length of a room by the width. This method only works where there are no alcove or fireplace details. For example, a rectangular room measuring 6.0m x 3.0m would require 18m2 of flooring.

Carpeting vs tiling

For flooring provided in planks or tiles you simply measure each space, calculate the areas of each, then add these areas together for the total required. You then buy enough per suppliers’ instructions to cover the area calculated. For example, room 1 shown below. We would recommend buying 20m2 to accurately cover this area.

When carpeting a room like this, we would suggest taking each measurement to the widest and longest point of the room. This then allows you to cover the space without any joins. Looking at room 2, you would multiply 4.0m by 6.0 meters coming to 24m2. This would allow you to cover the area with one stretch of carpet, producing a professional finish with no joins.

Indentations & Recesses

It is unusual that a space is void of an alcove, window, or fireplace detailing. Flooring must often be cut to fit around these architectural details. Again, measuring these spaces can vary depending on the flooring you are using.

Where tiled flooring is being used, measure the area of each space and add them together for the total area.

With carpeting, where a seamless finish is desired you must measure from the widest and longest part of the room and multiply to learn the overall area of the space.

In the given example you can see there is a 5m2 difference in the total amount required.


For staircases where each of the steps are identical in shape and size you must measure two faces.

  • First the top of the step. Measure the length and width of the tread to learn the area.
  • Secondly, the height of the step (the riser). Measure the length and height of the step to learn the area.

Add these two to learn the area required per step.

Multiple the step area by the number of steps. You may remove the top step where the landing flooring will be placed.



Landings come in a variety of different shapes and sizes, with awkward joins.

When using tiled flooring, much as a room with unique spaces, you simply measure each area and add them together to learn the total area required. Remember to include the top step in this measurement.

For carpeting, you extend the length and width to the widest section and multiple to learn to total area of carpet needed to cover the floor with no joins.

This is further explained in the above diagram.


  • Use a measuring tape and calculator. You don’t want a mental maths mistakes to be your downfall.
  • Calculate the total m2 figure of the room.
  • Measure twice, cut once! Double check each measurement!
  • Buy an additional 10% of each material to allow for offcuts and correct board layout.
  • If in doubt, phone use for help and advice. Our flooring installation team can visit and measure for you.
