Measuring Guide

Flooring Measuring Guide

First and foremost, if you are based in Bristol, Bath or the surrounding areas and you would like your new floor supplied and professionally fitted, contact us now to book a free measure and quotation. If in any doubt, always seek a professional help, as an incorrect measure can be costly. Plus, there is a lot more to our measuring service than just getting the size, we also make notes of the floor condition and note any preparation and thresholds required etc.

Here at Design Flooring, we recommend all floorcovering spaces to be professionally surveyed and measured

First things first, you will need the following;

Pencil or pen
Tape Measure

Draw a sketch of the area, and mark on doors and alcoves etc.

Check to see how square the area is by taking multiple measurements along parallel walls.

Write down the measurements as you take them, and always check them twice.

We will now go through the basic steps you need to follow for the different types of flooring and the rooms around the house.

Carpet & Vinyl


Grab your tape measure and measure the length and width of the room at the widest points. Remember to take into account any elements such as alcoves & to measure through doorways to meet the adjacent floor covering.

Make a note of the floorcovering which the new carpet will be butted up to, to obtain the correct threshold.

Always add 10 centimetres to your total length and width measurements. This will allow for any deviations in the wall & the cutting of the carpet / vinyl when it is fitted and ensures a good finish. Be careful as many rooms are not square and even allowing 10cm will not always be enough.

It helps if you know the widths available in the floor covering you plan to use. As a basic rule of thumb, Vinyl sheet is available in 2,3 & 4m width, whereas carpets are generally 4 and 5m. Armed with this knowledge you can also plan any joins required.

If the area is wider than the width of floor covering available, use your sketched plan to work out where you may have excess carpet to fill the missing spaces. Always have join pieces running in the same direction as the main piece. If there is a pattern, then you will need to find the pattern repeat and allow enough to obtain a match. The fitter may also need excess on the width and join pieces to allow for cutting back to obtain a clean join.

Hall, Stairs & Landing

Draw each area in turn.

Take your measurements, remembering the landing carpet folds over the top step down to the next and this needs to be measured in one. Carpet generally is designed to run in its length over steps.

Straight stairs – measure the width and total length ( tread and riser in one ) The average stair is about 45cm in length, and for planning 50cm is allowed. Most professional estimators would measure the width of each stair and count the quantity of stairs, allowing 50cm in length for each.

Winding stairs are measured by total length ( folding over the step ) and total width.

The fun part is to get the landing, hall and stair measurements planned onto one piece of carpet. Start with a piece of paper and draw an oblong scaled to the width of the carpet being used. Scale draw the landing and hall sections on first and then try and work all the stairs into the excess spaces. This may take a bit of trial and error. A professional estimator will be able to plan the carpet required ensuring the carpets are all in the correct direction with the minimum amount of waste.

Over all, we strongly recommend stairs and landings are professionally measured, either by ourselves or you carpet fitter.

Wood & Laminate Flooring

This is much more simple, simply divide the areas to be measured in to squares, measure the length and width of each square and then add them together. This will give you the total square meterage required. You of course will need some excess for cutting.

More importantly with theses area is to think about the edges, will you need new skirting boards or perimeter beading etc, and make a note of all the thresholds required.

Do I need stair rods?

Stair rods are purely decorative however do add a smart finishing touch. Please see our stair rod section on our website to view the different styles available.

Which width of stair runner should I choose?

We recommend that you have a minimum margin of 5cm either side of your runner and the edge of your staircase.

I have winding steps. Can I still have a stair runner?

A flatweave quality is recommended if you have winding steps as it is supple and flexible unlike a wilton. In the majority of cases where you have a minimum of three winding steps over a 90 degree turn the stripes can be matched in the crutch of the step if a flatweave is used. A good Roger Oates trained fitter is essential.

How much will I need?

  1. For straight steps, measure one riser and one tread to give the length need for each step. Include the “nose” in the measurement ). Check that all treads and risers on your stairs have the same measurements.
  2. Count steps and check for differing depths.
  3. Multiple the number of steps x length needed for each step. If the steps all have different measurements, you will need to measure each one individually and add the measurements together.
  4. To calculate the quantity needed for winding steps, measure the distance along the outside perimeter.
  5. Measure the final riser of the flight and also add an extra 50cm per flight to allow for tolerance.
