Thickness of Carpets: Guide to Thickness, Density and Durability of Carpets

 

Choosing the right carpet for your home involves much more than simply picking a colour or style. Carpet thickness, density, and durability all play an important role in how your flooring looks, feels, and performs over time. Whether you are furnishing a bedroom, hallway, stairs, or a full house, understanding these key carpet features can help you make the best long-term investment for your home.

In this guide, we explain everything you need to know about thick carpets, including how carpet thickness affects comfort, what carpet density means, and which carpets are best for durability in busy UK households. The below table is a beginners guide, with the Total Thickness height being the carpet pile thickness including the backing. The Pile Height excludes the backing thickness.

Carpet Type

Typical Total Thickness (mm)

Typical Pile Height (mm)

Berber / Loop

5mm–11mm

4mm–9mm

Low Pile / Commercial

5mm–12mm

3mm–11mm

Medium Pile

12mm–15mm

11mm–14mm

Thick Carpet

16mm–21mm

14mm–19mm

Deep Pile

20mm+

19mm+


What Is Carpet Thickness?

Carpet thickness refers to the height of the carpet pile, measured from the backing to the surface fibres. In simple terms, thicker carpets have taller fibres and usually feel softer and more luxurious underfoot.

Many homeowners assume that thicker carpets automatically mean better quality, but this is not always the case. While a thick carpet can provide extra comfort and warmth, the carpet’s density and fibre quality are equally important when choosing flooring that will last.

Foz who is a sales lead for Carpets Online often gets asked about Carpet Thickness, “Customers often want thick carpets for their living room and bedrooms, we stress that it is not just about thickness but also the density that is important”.

Typical Carpet Thicknesses

Carpet thickness can vary depending on the carpet style:

Deep pile and thick carpets are particularly popular in bedrooms and lounges where comfort is a priority.

What Is Carpet Density?

Carpet density refers to how closely packed the carpet fibres are together. A dense carpet has more fibres per square metre, making it more durable and resistant to flattening. Carpet Density is one of the most important factors yet is often overlooked by households.

This is one of the most important factors when choosing a long-lasting carpet for busy areas such as:

  • Hallways 
  • Stairs 
  • Living rooms 
  • Family homes with pets or children 

A carpet with high density will often outperform a thicker but loosely packed carpet.

When shopping for carpets in the UK, it is important to balance thickness with density to ensure you get both comfort and durability.

Why Density Matters

High-density carpets offer several benefits:

  • Better resistance to wear and tear 
  • Improved appearance retention 
  • Greater comfort underfoot 
  • Increased insulation and sound reduction 
  • Longer carpet lifespan 

Does a Thicker Carpet Mean Better Quality?

Not necessarily. While thick carpets feel luxurious, the quality of the fibres and construction are just as important.

For example:

  • A very thick carpet with low density may flatten quickly in busy areas. 
  • A medium-thickness carpet with high density can last much longer and maintain its appearance. 

Rhys, a former carpet fitter who now does house measures and sales states “We often suggest to customers not to go for really thick deep pile carpets for the stairs” when asked if thick carpets are suitable for the stairs and hallways.

This is why professional carpet fitters and flooring experts often recommend focusing on overall carpet performance rather than thickness alone.

Best Thick Carpets for Different Rooms

Different rooms in the home require different types of carpet depending on foot traffic and usage.

Thick Carpets for Bedrooms

Bedrooms are ideal for thick, soft carpets because they provide warmth and comfort underfoot. Saxony carpets and deep pile carpets are popular choices for creating a cosy feel.

Benefits include:

  • Soft texture 
  • Warmth during colder months 
  • Luxurious appearance 
  • Noise reduction 

Thick Carpets for Living Rooms

Living rooms benefit from carpets that balance comfort and durability. Dense twist pile carpets can offer a softer feel while still standing up to regular use.

Thick Carpets for Stairs and Hallways

Although thick carpets may seem appealing, very deep pile carpets are not always suitable for stairs and hallways. These areas experience heavy foot traffic and require hard-wearing carpets with excellent durability.

Low to medium pile dense carpets are often the best option for these spaces

Carpet Thickness and Underlay

Underlay plays a major role in how thick and comfortable a carpet feels. A quality carpet underlay can improve:

  • Comfort underfoot 
  • Heat insulation 
  • Noise reduction 
  • Carpet lifespan 
  • Energy efficiency 

In many cases, a good underlay combined with a medium-thickness carpet can feel more comfortable than a very thick carpet with poor underlay.

Which Carpet Materials Are Most Durable?

The durability of a carpet also depends on the type of fibre used.

Polypropylene Carpets

Polypropylene carpets are one of the most popular choices in the UK because they are:

  • Stain-resistant 
  • Affordable 
  • Easy to clean 
  • Suitable for busy homes 

Wool Carpets

Wool carpets are known for their luxury appearance and natural durability. They are highly resilient and can maintain their appearance for many years.

Polypropylene and Polyester Carpets

Nylon carpets are extremely durable and resistant to crushing, making them suitable for high-traffic areas. At Carpets Online, the thickest carpet stocked is the Dreams 20mm due to its high density. Thicker carpets are available, however they are not stocked due to chances of flattening.

How to Choose the Right Carpet Thickness?

When choosing carpet thickness for your home, consider:

Foot Traffic

  • Busy areas require durable and dense carpets rather than simply thick carpets.

Comfort

  • Bedrooms and lounges may benefit from thicker carpets for added softness.

Maintenance

  • Deep pile carpets can require more vacuuming and maintenance compared to shorter pile carpets.

Budget

  • Thicker and denser carpets are often more expensive, but they can provide better long-term value.

Are Thick Carpets Good for Insulation?

Yes, thick carpets can help improve insulation within the home. Combined with quality underlay, carpets help retain heat and reduce energy loss through floors.

Benefits include:

  • Warmer rooms during winter 
  • Reduced heating costs 
  • Better sound insulation 
  • Improved comfort throughout the home 

This makes thick carpets particularly popular in UK homes where energy efficiency is important.

Common Mistakes When Choosing Thick Carpets

Many homeowners make the mistake of focusing only on softness and thickness. However, other factors matter too.

Avoid:

  • Choosing very thick carpets for stairs 
  • Ignoring carpet density 
  • Using poor quality underlay 
  • Prioritising appearance over durability 
  • Selecting unsuitable carpets for high-traffic areas 

A balanced carpet choice will provide both comfort and long-lasting performance.

Summary

Thick carpets can add warmth, luxury, and comfort to any home, but thickness alone does not determine carpet quality. Carpet density, fibre type, underlay, and durability all play an important role in choosing the best carpet for your space.

For busy family homes, it is important to find a carpet that combines comfort with long-lasting durability. By understanding the relationship between carpet thickness, density, and performance, you can choose flooring that looks great and stands the test of time.

Whether you are carpeting a single room or fitting carpets throughout your entire home, investing in the right carpet and underlay will help create a comfortable and practical living space for years to come.
