How To Measure For Carpets

Choosing a new carpet is a significant part of any home improvement project. This crucial aspect of your interior can create a warm and welcoming environment, reflecting your unique personal style. But beyond the excitement of choosing the perfect pattern or colour, one critical practical element often overlooked is accurately measuring the carpet. Miscalculations not only lead to unnecessary expenses but can also disrupt the harmony of your space, wasting both time and resources.

This comprehensive guide aims to arm you with the essential knowledge and confidence to measure your carpets accurately. By understanding how to properly assess the size of the area you’re carpeting, you’ll be equipped to avoid common mistakes, saving both time and money. It’s a straightforward process, and with a little patience and precision, you’ll be well on your way to a beautifully carpeted room or staircase.

Basic Essentials of Carpet Measurement

Before diving into the specifics of carpet measurement, it’s important to familiarise yourself with the basic essentials. Having the right tools can make the process smoother and more precise. A metal measuring tape is recommended over a fabric one, as it is sturdier and less likely to stretch or distort.

Alongside this, make sure to have a reliable pen and plenty of paper on hand to record your measurements accurately. A calculator will be necessary to compute areas and convert units if needed.

Carpets in the UK are typically measured in square metres (m²), which considers both the length and width of the area to be covered. It’s a simple yet effective method of ensuring you purchase the correct amount of carpet for your space. Knowing this, you can now prepare your measuring tools and get ready to start the measuring process!

Step-by-Step Process of Measuring a Room for Carpet

Measuring a room for a carpet involves calculating the area. This is done by measuring the length and width of the room at their longest points in metres, then multiplying these figures together, yielding the total area in square metres. This method works well for regular rectangular or square rooms.

However, many rooms don’t conform to this simple shape. If you’re dealing with an L-shaped room, rooms with bay windows, or rooms with alcoves, it’s best to divide the room into separate rectangles and measure each of them separately.

Moreover, remember to add an extra 10 centimetres to each dimension to allow for trimming during fitting – it’s far easier to trim excess than to add to a piece that’s too short.

How to Measure Carpets for Stairs

Staircases require a different approach when measuring carpets. Unlike a flat room, stairs have both horizontal treads and vertical risers to consider, along with the width of the stair. Start by measuring the width of the stair, followed by the depth (tread) and height (riser) of one step. Multiply the tread and riser measurements together, then multiply this figure by the total number of steps.

If your staircase curves or includes winders, these should be treated as unique areas, requiring individual measurements. This might seem like a daunting task, but it is essential to achieve an accurately fitted carpet that complements the curve and contour of your staircase.

What Unit to Measure Carpets in

In the UK, carpets are typically measured in square metres (m²). This unit of measurement helps to ensure consistency and accuracy, accounting for both the length and width of the space to be carpeted. Using a standard unit also simplifies communication with carpet retailers and fitters, reducing the risk of misinterpretation.

If you’ve initially taken your measurements in a different unit, perhaps feet or yards, it’s essential to convert these into square metres before ordering your carpet. There are numerous online conversion tools available which can help with this. Providing your carpet measurements in the standard UK unit of square metres helps to ensure a seamless purchase and installation process, keeping confusion and potential mistakes to a minimum.

Common Mistakes to Avoid When Measuring for Carpets

There are a number of common pitfalls that can lead to miscalculations when measuring for carpets. One such mistake is failing to account for door clearances. Depending on the thickness of your new carpet, doors may not open or close correctly, causing a major inconvenience after installation. Always ensure to check that the thickness of your chosen carpet does not interfere with door movement.

Another common mistake involves the direction of the carpet pile. Pile direction can influence how light interacts with the carpet, affecting its overall appearance. Ideally, the pile should run in the same direction throughout your room. Moreover, if you’re working with a patterned carpet, be sure to allow for pattern repeats. This may require ordering extra carpet to ensure the pattern aligns properly across the room.

Getting a Professional Measurement

Sometimes, despite our best efforts, we may find ourselves facing a complex carpet-measuring situation. Perhaps you’re dealing with an unusually shaped room or a multi-level staircase. In such scenarios, it might be beneficial to consider obtaining a professional measurement. Professionals are well-versed in handling tricky situations and can guarantee accuracy, saving you the headache of dealing with potential mistakes.

Professional carpet measurers not only offer precise measurements but also provide valuable advice on carpet types and styles suitable for your space. They can identify potential issues that may arise during fitting, which you might overlook due to lack of experience. When selecting a professional, ensure to consider their reviews and ask for recommendations to ensure you receive the best service.


The process of measuring carpets may seem daunting, but with the right knowledge and a little patience, it can be an easy task. By understanding how to measure your space accurately, you’re ensuring the best use of your resources and, ultimately, creating a more beautiful and comfortable living space.

Equipped with the insights from this comprehensive guide, you’re now ready to tackle your carpeting project with confidence.
