If you've ever shopped for bedding, you've almost certainly come across thread count. It's one of the most talked-about numbers in the world of home textiles — and one of the most misunderstood. Many shoppers assume that a higher thread count automatically means better quality, but the reality is far more nuanced than that.
At Deyongs, we've been crafting quality home textiles since 1846, and we know that thread count is just one piece of the puzzle. In this guide, we'll explain exactly what thread count means, why it matters (to a point), and what else you should be looking at when choosing bedding that genuinely feels luxurious.
What Is Thread Count?
Thread count refers to the number of threads woven into one square inch of fabric. It's calculated by adding together the number of horizontal threads (weft) and vertical threads (warp). So if a fabric has 150 horizontal threads and 150 vertical threads per square inch, it has a thread count of 300.
The idea is straightforward: more threads per inch should mean a denser, smoother, and more durable fabric. And up to a certain point, that's absolutely true.
Quick Tip: A thread count between 200 and 800 is the sweet spot for most quality bedding. Anything marketed above 1,000 should be approached with caution — the numbers are often inflated through multi-ply counting techniques.
The Thread Count Sweet Spot
Here's a general guide to what different thread count ranges actually feel like in practice:
200–400 TC
Soft, breathable, and ideal for everyday use. This range is where you'll find excellent quality cotton percale sheets that feel crisp and cool — perfect for warmer months or those who sleep hot.
400–600 TC
A step up in smoothness and density. Sateen weaves in this range feel silky and have a subtle sheen. This is the luxury sweet spot for most people — noticeably premium without the inflated price tag.
600–800 TC
Exceptionally smooth and dense. At this level, the quality of the cotton fibre becomes crucial. Long-staple Egyptian or Supima cotton at 600–800 TC delivers a genuinely indulgent feel.
800+ TC
Diminishing returns begin here. Some manufacturers use multi-ply yarns to inflate the number artificially. A genuine 800+ TC sheet made from single-ply long-staple cotton is rare and genuinely exceptional.
Why Thread Count Isn't Everything
Here's where it gets interesting. Thread count has become such a dominant marketing number that some manufacturers have found ways to game the system. The most common technique is using multi-ply yarns — twisting two or three thinner threads together and counting each one separately. A two-ply 300 TC sheet suddenly becomes a “600 TC” sheet on the label, even though it doesn't feel or perform any differently.
The truth is that several other factors matter just as much — if not more — than thread count alone:
1. Fibre Quality
The type and quality of cotton used is arguably the single biggest factor in how bedding feels. Long-staple cotton (like Egyptian cotton or Supima) produces smoother, stronger, and more lustrous fabric than short-staple cotton, regardless of thread count. A 400 TC sheet made from premium long-staple Egyptian cotton will feel significantly better than a 600 TC sheet made from lower-grade fibres.
2. Weave Type
The way threads are woven together dramatically changes the feel of the finished fabric. Percale weaves are crisp, cool, and matte — ideal for summer. Sateen weaves are silky, smooth, and have a gentle sheen — perfect for a more luxurious drape. Same thread count, completely different sleeping experience.
3. Finishing
How the fabric is finished after weaving — processes like mercerisation, calendering, and enzyme washing — can transform the hand feel, softness, and durability of bedding. A well-finished 300 TC sheet can genuinely outperform a poorly finished 600 TC sheet.
4. Single-Ply vs Multi-Ply
Always look for single-ply thread counts. Single-ply fabrics use one thread per count, producing lighter, more breathable, and genuinely smoother bedding. Multi-ply inflates the numbers without delivering the corresponding improvement in feel.
The Deyongs Approach
With over 175 years of textile expertise, we focus on what actually matters: sourcing the finest long-staple cotton, using expert weaving techniques, and applying premium finishing processes. We believe in honest thread counts that reflect genuine quality — never inflated numbers designed to mislead.
What to Look for When Buying Bedding
Next time you're shopping for sheets, duvet covers, or pillowcases, here's a quick checklist that goes beyond thread count:
- Check the cotton type — look for Egyptian cotton, Supima, or long-staple cotton for the best feel and longevity.
- Ask about the weave — percale for crisp and cool, sateen for silky and smooth.
- Look for single-ply — it's a sign of genuine quality rather than inflated numbers.
- Consider the weight — GSM (grams per square metre) can tell you about density and warmth.
- Feel before you buy — whenever possible, touch the fabric. Your hands know quality better than any number on a label.
Thread Count for Towels: A Different Story
It's worth noting that thread count doesn't apply to towels. Towels are measured by GSM (grams per square metre), which indicates their density and absorbency. A higher GSM means a thicker, more absorbent towel. For a luxurious bath towel, look for 500–700 GSM.

Did You Know? The concept of thread count only became a major marketing tool in the early 2000s. Before that, shoppers relied on touching fabrics and trusting reputable brands — something that's still the most reliable method today.
The Bottom Line
Thread count is a useful starting point, but it's far from the whole story. The best bedding comes from a combination of premium fibres, expert weaving, quality finishing, and honest manufacturing. A 400 TC sheet made from the finest Egyptian cotton will outperform a 1,000 TC sheet made from inferior fibres every single time.
At Deyongs, we've spent over 175 years perfecting the art of home textiles. We don't chase inflated numbers — we focus on making bedding, towels, and throws that feel exceptional and last for years. Because true quality is something you feel, not something you count.
