When choosing bed linen, the concept of thread count often comes up. In Europe, thread density is measured in threads per square centimetre, while in Anglo-Saxon countries, the term thread count is used. Both indicators refer to weaving density, but they can be confusing to compare. Understanding these concepts helps you better evaluate fabric quality, while also taking into account other essential criteria such as material and weave.
Threads and thread count: two ways to measure density
Threads per square centimetre
In Europe, density is expressed in threads per square centimetre. This indicator gives a precise idea of the fineness of the weave and the quality of the bed linen. For example, a fabric with 80 threads/cm² is considered a very good quality level for everyday bed linen.
Thread count
Thread count refers to the number of threads per square inch. This unit is widely used in Anglo-Saxon countries, particularly in the hotel industry. A fabric listed at 200 TC therefore corresponds to a European fabric of 80 threads/cm².
Conversion table: threads/cm² and thread count
To easily compare the two systems, here is a practical conversion table:
| Threads/cm² (Europe) | Thread Count (Anglo-Saxon) | Indicative quality |
|---|---|---|
| 40 threads/cm² | 100 TC | Entry level |
| 57 threads/cm² | 150 TC | Good value for money |
| 80 threads/cm² | 200 TC | Good quality, everyday comfort |
| 120 threads/cm² | 300 TC | Superior quality, silky feel |
To remember: to convert threads/cm² to thread count, multiply by 2.5. To do the reverse, divide the thread count by 2.5.
Why these two measurements can be confusing
A conversion that is not always straightforward
The same fabric can display a very different figure depending on the unit used. A European fabric at 80 threads/cm² will be listed at 200 TC in an Anglo-Saxon catalogue, which may seem low when it is actually very good quality. Conversely, a fabric at 120 threads/cm² listed at 300 TC may appear modest compared to products displaying 600 or 800 TC, which are often artificially inflated.
Variable marketing practices
Some manufacturers may highlight high thread count figures without this necessarily reflecting better quality. A very high thread count (600, 800 TC) can result from an artificial counting of twisted threads, counted individually, which distorts the comparison.
Is thread count a guarantee of quality?
A balance between density and breathability
A high thread count can offer a smoother fabric, but too dense a weave can limit breathability. Good bed linen generally sits between 60 and 120 threads/cm² (150 to 300 TC), the ideal balance between softness, lightness and durability.
The importance of fibre quality
The length and quality of cotton fibres play an essential role. Long fibres, such as Egyptian cotton or Pima cotton, produce a softer and more resistant fabric, even at equivalent density. A fabric at 80 threads/cm² in long-staple cotton will often be more pleasant than a fabric at 120 threads/cm² in standard cotton.
The materials that influence comfort
Cotton percale
Percale is characterised by a tight weave, generally from 80 threads/cm² (200 TC), and a cool feel. It is ideal for those looking for light, breathable bed linen, perfect for summer nights.
Cotton sateen
Cotton sateen offers a smoother, silkier feel. It provides an enveloping and elegant sensation, often associated with levels of 120 threads/cm² (300 TC) and above.
Natural materials
Cotton, linen or cotton gauze allow good air circulation and lasting comfort, regardless of thread count.
How to choose your bed linen in practice
Prioritise quality materials
Quality cotton, made from long fibres and certified Oeko-Tex® or GOTS, guarantees softness and durability well beyond a simple density figure.
Choose a weave suited to your preferences
Percale for freshness, sateen for softness, each weave offers a different experience. For everyday use, a weave at 80 threads/cm² (200 TC) in quality percale or sateen is more than sufficient.
Do not rely solely on the figure
Thread count should not be the only criterion. A fabric at 80 threads/cm² (200 TC) in certified long-staple cotton will often outperform a fabric at 200 threads/cm² (500 TC) in low-grade cotton.
FAQ: threads and thread count
What is the difference between threads/cm² and thread count?
Both measure weaving density, but use different units: square centimetre in Europe, square inch in Anglo-Saxon countries. 80 threads/cm² is equivalent to 200 TC.
Is a higher thread count better?
Not necessarily. The quality of fibres and weave is just as important. A 200 TC in long-staple cotton is often better than an artificially inflated 600 TC.
What thread count should I choose for good bed linen?
A weave between 60 and 120 threads/cm² (150 to 300 TC), combined with quality fibres, generally offers the best everyday comfort.
How do I convert threads/cm² to thread count?
Multiply the number of threads/cm² by 2.5. Example: 80 threads/cm² × 2.5 = 200 TC. For the reverse, divide the thread count by 2.5.
