This page is for buyers comparing spec sheets that list different weights for products that look similar. You will learn what each number measures, how they combine, and how to run a quick calculation that shows whether a high face weight comes from density or simply from taller blades.
What is face weight vs total weight?
Face weight is the weight of the yarn above the backing, expressed in ounces per square yard in the US. It tells you how much fiber you are buying. See the glossary entry for face weight.
Total weight is face weight plus the primary backing, the secondary coating and any yarn locked in the backing. Coatings typically add about 20 to 35 oz per square yard, so a product with 60 oz face weight often has a total weight in the 85 to 95 oz range.
Some listings quote only "weight." If it is not labeled, assume it is total weight until shown otherwise, because that is the larger and more flattering number.
What are gauge and stitch rate?
Turf is tufted like carpet: needles punch yarn through the primary backing in parallel rows.
- Gauge is the distance between rows, in fractions of an inch. Common landscape gauges are 3/8, 1/2 and 5/8 inch. Smaller gauge means rows closer together.
- Stitch rate is how many tufts are placed along each row per unit length, often quoted per 4 inches, per 10 cm or per meter. Higher stitch rate means tufts closer together within a row.
Multiply the two and you get tufts per unit area, which is the most direct measure of density. A tight gauge with a low stitch rate can have the same tuft count as a wider gauge with a high stitch rate, but the tight gauge usually looks more even because rows are less visible.
What is Dtex and how does it relate to denier?
Dtex (decitex) is the mass in grams of 10,000 meters of yarn. Denier is the same idea per 9,000 meters, so 1 denier is about 1.11 dtex. Turf yarns are usually quoted as the Dtex of the full bundle that goes into one tuft, often 8,000 to 16,000 for landscape products, sometimes with the number of strands per bundle.
Higher Dtex at the same strand count means thicker, heavier blades: more durable and stiffer. Higher Dtex from more strands means a fuller tuft. A spec that lists only Dtex without strand count or blade thickness (often in microns) tells you the weight of the bundle, not the character of the blades.
How do these numbers interact?
Face weight is the product of four things: tufts per square yard, yarn length per tuft, and the yarn's mass per length (Dtex), plus a small allowance for the yarn loop under the backing. Written out:
- Tufts per sq yd = (1 / gauge in inches) x (stitches per inch) x 1,296
- Yarn per tuft (inches) = 2 x pile height + backing loop
- Face weight (grams) = tufts x yarn per tuft in meters x Dtex / 10,000
- Divide grams by 28.35 to get ounces
Each tuft has two legs (it goes up and comes back down through the backing), which is why pile height is doubled. Manufacturers vary on whether the loop under the backing counts toward face weight; the difference is small.
Why does face weight alone mislead?
Because pile height sits inside the formula. Make the blades taller and face weight climbs, even if the tufts are no closer together and the yarn is no thicker. Two products can show a 15 oz difference in face weight while having identical density.
The reverse also happens. A short, dense pet turf may have a lower face weight than a tall decorative product, yet stand up far better under traffic because there are more tufts per square inch supporting each other.
How dense should artificial turf be?
Our working targets for residential products, expressed as tufts per square foot (tufts per sq yd divided by 9):
| Use | Tufts per sq ft | Typical gauge | Notes |
|---|---|---|---|
| Decorative, low traffic | 1,000 to 1,400 | 1/2 to 5/8 in | Taller pile fills in visually |
| Family lawn | 1,300 to 1,800 | 3/8 to 1/2 in | Tight rows hide the backing |
| Dogs and high traffic | 1,500 to 2,200 | 3/8 in | Mutual support resists matting |
| Putting green | 3,000 and up | 3/16 to 3/8 in | Very short, very dense |
These ranges are approximations from typical gauges and stitch rates in the market; manufacturers do not always publish enough to calculate them. Product A in the worked example lands at 13,824 / 9 = 1,536 tufts per sq ft, comfortably in the family range.
Field test: estimate density from a sample
If the spec sheet omits gauge or stitch rate, you can count it.
- Turn the sample face down and look at the back, where the stitch rows are visible.
- Measure 4 inches across the rows and count how many rows fall in that span; divide 4 by the count to get gauge.
- Measure 4 inches along one row and count the stitches; divide by 4 for stitches per inch.
- Multiply (1 / gauge) x stitches per inch x 144 to get tufts per sq ft.
- Compare against the table above and against the product's claimed face weight and pile height.
What most guides get wrong
The typical advice is "aim for 80 oz or more." That threshold ignores pile height and treats total weight and face weight as interchangeable. An 80 oz total weight product may have only 50 oz of yarn. An 80 oz face weight product at 2.25 inches can be less dense than a 65 oz product at 1.25 inches. Always ask which weight is quoted, then check pile height and tuft count. Our spec sheet walkthrough shows where each number appears and how to cross-check them.

Frequently asked questions
Is 60 oz turf good enough for a backyard?
Often, yes, if it is face weight on a product around 1.25 to 1.5 inches with a gauge of 3/8 or 1/2 inch. That combination gives reasonable density for family use. If 60 oz is total weight, the yarn content may be closer to 30 to 40 oz, which is light for daily traffic. Confirm which weight is listed and check pile height before judging the number.
Does higher density make turf hotter?
Slightly. More fiber per square foot means more plastic surface absorbing sunlight and less airflow near the base. In practice the difference between typical residential densities is small compared with the effect of shade, color and infill type. Density's benefits for resilience and wear usually outweigh the modest heat penalty, so do not choose sparse turf in hopes of a cooler surface.
Why do some spec sheets list stitches per meter?
Manufacturers use the units of their tufting machines and home markets, so you will see stitches per 4 inches, per 10 cm, per meter or per foot. Convert to stitches per inch to compare: divide per-4-inch figures by 4, per-10-cm by 3.94 and per-meter by 39.37. A product listing 160 per meter is about 4 per inch, which is ordinary, not exceptionally dense.
Can density be too high for infill?
Yes. Very dense, short turf leaves little space between tufts, so infill sits on top instead of settling to the backing. That makes infill more likely to kick out or wash into piles. Dense pet and putting products are often designed for light infill or none. Follow the manufacturer's infill guidance for the specific product rather than a generic pounds-per-square-foot figure.
