How to Tell a Good Carpet
From a Cheap One

You can judge a carpet in 60 seconds without looking at the price tag. Most people do it backwards: they look at the price, then the colour, and never read the label that tells them how long the thing will actually last.

Three things decide carpet quality — fibre, pile weight and twist — and all three are printed on the label or visible in your hands. Here's how to read them like someone who sells carpet for a living.

1. Fibre: What It's Made Of

The fibre sets the personality of the carpet:

• Polypropylene — the budget workhorse. Stain-resistant and bleach-cleanable, which is why it's the go-to for families, rentals and anyone with red-wine habits. Its weakness: it recovers from flattening less well than wool, so on busy floors buy a heavier weight.
• Polyester — softer and warmer than polypropylene, often with high insulation. Lovely in bedrooms; less suited to stairs.
• Wool and 80/20 wool blends — the premium choice. Wool is naturally springy: it bounces back from footprints and furniture better than any man-made fibre, hides soil well and ages gracefully. An 80% wool / 20% nylon blend adds tensile strength to that spring — it's the classic quality formula for a reason.

No fibre is "best". A bleach-cleanable polypropylene is genuinely the smarter buy for a young family's lounge; wool wins for the long haul. Match the fibre to the life the room leads — our room-by-room carpet guide goes deeper.

2. Pile Weight: The Most Useful Number on the Label

Pile weight is how much fibre is packed into each square metre, given in ounces (oz) or grams (g/m²). More fibre means more to wear through, better recovery and a denser feel. The rough ladder:

Pile weight	What it means	Right for
~32oz and under	Budget weight	Spare rooms, short-term lets
~40oz (≈1,350g/m²)	Solid everyday carpet	Bedrooms, living rooms
50–60oz	Quality family weight	Lounges, stairs, halls
70–80oz	Heavy & luxurious	Anywhere you want it to feel — and stay — special

Two carpets can look identical on the rack. The label says which one still looks like that in five years.

3. Twist: Why Some Carpets Never Flatten

Pick up a sample and look at a single tuft. In a twist pile, each tuft is wound tight like a little spring — the tighter the twist, the better it stands back up after a footstep. That's why twists rule on stairs and in halls. A saxony has longer, softer, straighter tufts: gorgeous underfoot, but it'll show footprints and vacuum marks — fine in a bedroom, a regret in a hallway. Loop piles (cords and berbers) are the tough all-rounders, with one caveat: cat claws and loops don't mix.

The 60-Second Shop Test

Put it together at the rack — no label needed:

1. The bend test. Fold the sample back on itself, pile outward. If you can easily see the backing grinning through, the tufts are sparse — it'll flatten fast and wear at the seams. A dense carpet barely shows its backing.
2. The thumb test. Press your thumb in hard and let go. Quick spring-back = good recovery. Slow, sulky recovery in the shop = a flat path to the sofa within a couple of years at home.
3. The label check. Fibre, pile weight, warranty. A maker confident enough to print 10–15 years is telling you something; so is one that prints nothing.

What Quality Doesn't Mean

Two things people overrate. Softness — softness is a feel, not a grade; some of the softest carpets are the quickest to flatten. And price — a mid-range carpet on a quality underlay beats a premium carpet on a cheap one, every time. The underlay decides half of how a carpet performs, so judge them as a pair. If you want to know how the lifespan maths plays out, see how long carpet lasts.

Frequently Asked Questions

What is a good pile weight for carpet?

Around 40oz is a solid everyday carpet, 50–60oz is a quality family-home weight, and 70–80oz is heavy, luxurious territory. Below about 32oz you're at the budget end — fine for a spare room, not for stairs.

Which carpet fibre is best?

The right one for the job. Polypropylene for stain-proof family value, polyester for soft warm bedrooms, wool and 80/20 blends for spring-back and graceful ageing on the floors you'll live with longest.

How can I check carpet quality in the shop?

Bend the sample back on itself — if the backing shows through easily, the pile is sparse. Then press your thumb in and watch the recovery. Sixty seconds, no label required.
