The performance benchmark for cut-pile carpet. Typical installed cost, durability, where it works and how to care for it.
Nylon (polyamide) is the most resilient carpet fiber in common use. Its molecular structure lets crushed fibers "bounce back" when heat and moisture are applied, which is why nylon holds its appearance in hallways and stairs long after cheaper fibers have matted flat. Type 6,6 nylon is denser and slightly more stain- and abrasion-resistant than Type 6; both are excellent. Nearly all quality nylon today is solution-dyed or has a factory-applied stain treatment.
Type 6,6 tests roughly 20% higher in tensile strength and about 12% higher in surface hardness, and costs 10–15% more. In practice the gap has narrowed a great deal: modern fluorochemical and acid-dye-resistor treatments are applied to both, and experienced cleaners often describe current products as difficult to tell apart. Type 6 dyes more readily and depolymerizes for recycling. Both outperform every non-nylon fiber.
Color is added to the liquid polymer before the fiber is extruded, so it runs all the way through. Result: essentially bleach-proof and fade-proof. Costs more than piece-dyed but is the single best durability upgrade you can buy.
Face weight (oz/yd²) is only half the story. Average pile yarn density = face weight × 36 ÷ pile height, in oz/yd³. Typical results land between about 1,000 and 7,000; the Carpet and Rug Institute recommends 5,000 or higher for extra-heavy traffic. A dense 40 oz beats a fluffy 55 oz.
How tightly the yarn is twisted, and whether it is heat-set. Higher twist resists the "frizzing" that makes traffic lanes look dirty. Look for 5+ turns per inch on frieze.
A separate purchase that determines how long the carpet lasts. 8 lb density, 7/16" thick is the residential standard. Too-thick pad voids warranties and causes seam failure.
| Typical face weight | 35–60 oz/yd² |
|---|---|
| Warranty range | 10–25 yrs texture retention |
| Roll width | 12 ft (some 15 ft) |
| Reclaim | Widely recycled — nylon 6 is depolymerizable |
If you buy one upgrade, make it solution-dyed nylon over a quality 8 lb pad. It costs roughly 15% more and routinely doubles usable life.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
Color runs through the strand instead of sitting on it, so bleach spills and years of sunlight cannot pull it out. This is the single upgrade that most reliably doubles usable life.
The yarn holds its shape instead of unravelling into fuzz. Traffic lanes stay looking like carpet rather than turning into a permanent grey path to the sofa.
Crushed pile springs back when heat and moisture are applied during cleaning. A nylon floor recovers from a heavy sideboard; polyester keeps the dent.
Tufts support each other so foot pressure spreads instead of splaying the pile. Density predicts appearance retention better than any other number on the label.
Cuts both footfall heard below and echo within the room. In a condo it is often the cheapest way to satisfy an acoustic requirement in the bylaws.
Drawn from the same ratings used everywhere else on this site, so this cannot flatter the product beyond what the comparison table says.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Nylon Carpet runs $4.00–$10.00 per square foot installed in 2026 — $2.50 to $7.00 for material and $1.50 to $3.00 for professional labor. Spread across an expected 10 to 20 year service life that works out near $0.47 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
10 to 20 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. If you buy one upgrade, make it solution-dyed nylon over a quality 8 lb pad. It costs roughly 15% more and routinely doubles usable life.

Vacuum high-traffic lanes daily-to-weekly with a beater bar set to the correct pile height. Blot spills immediately — never rub, which drives soil into the backing. Critically: never use bleach or high-ph cleaners on non-solution-dyed nylon.
