The short answer
Face weight is the weight of the yarn alone in a given area of artificial grass, usually quoted in grams per square metre. It counts only the visible fibres, not the backing or infill, which is why it is one of the most telling numbers on a spec sheet: a higher face weight means more yarn packed in, so the lawn looks fuller, feels plusher and generally wears better. It effectively combines yarn thickness (Dtex) and density (stitch rate) into a single figure. Be careful not to confuse it with total weight, which adds in the heavy backing and can make a thin grass look impressive on paper. For comparing how substantial two grasses really are, face weight is usually the more honest number.
Face weight is a number worth learning, because it cuts through marketing. While pile height tells you the look, face weight tells you how much actual grass yarn you are buying — a strong clue to fullness and lifespan.

What face weight measures and why it matters
Face weight is the mass of the yarn (the blades) contained in one square metre of grass, given in grams per square metre (g/m2). Crucially, it counts only the fibres you see and touch — the backing and any infill are excluded. That makes it a clean measure of how much actual grass you are getting.
A higher face weight means more yarn has been tufted into the same area, which usually delivers:
- A fuller, denser appearance that hides the backing better.
- A plusher feel underfoot.
- Better durability and recovery, because there is more fibre to share the load of footfall.
Because it rolls yarn thickness and density together, face weight is one of the most useful single figures for judging quality, and a good number to compare across products.
Face weight versus total weight
The most common trap is mixing up face weight with total weight. They are not the same:
- Face weight: the yarn only. This is the figure that reflects how much grass fibre you are buying.
- Total weight (or roll weight): the yarn plus the backing. Because backings can be heavy, a grass with a thin pile but a heavy backing can quote a high total weight while actually being quite sparse on top.
A product marketed purely on its total weight can therefore look better than it is. When comparing grasses, always check which figure is being quoted, and ask for the face weight specifically if it is not listed. A high face weight is a far stronger indicator of a plush, hard-wearing lawn than a high total weight.
| Figure | What it includes | What it tells you |
|---|---|---|
| Face weight | Yarn / blades only | Fullness and durability |
| Total weight | Yarn plus backing | Overall heft (can mislead) |
| Pile height | Blade length | Look and feel |
| Dtex | Single yarn thickness | Robustness of each blade |

How to use face weight when buying
The practical way to use face weight is alongside the other key figures rather than in isolation:
- Pick a pile height that suits the area's use (shorter for traffic, medium for lawns, longer for ornamental).
- Among grasses of that height, compare face weight — a higher figure generally means a fuller, longer-lasting lawn.
- Sanity-check with Dtex and stitch rate, which describe yarn thickness and tuft spacing.
- Finally, order a sample and feel it, because no spec fully captures softness, colour and how upright the pile stays under pressure.
A higher face weight usually costs more, because there is more raw yarn in the product — but for an area that will be used heavily, that extra fibre is what keeps the lawn looking full rather than worn and flattened over time. For a lightly used ornamental area, a more moderate face weight can be perfectly adequate.
Why face weight links to durability and value
The reason face weight is such a good predictor of how a lawn ages is simple: more yarn means more material to share the wear. When you walk on artificial grass, the load is spread across the blades in that area. A high-face-weight grass has more blades per square metre, so each one carries less of the burden, the pile flattens less and it recovers more readily. A sparse, low-face-weight grass concentrates the same footfall onto fewer blades, which crush and mat faster — and once the pile lies flat and the backing starts to show, the lawn looks tired well before its time.
This connects directly to value. Artificial grass is priced largely by how much yarn it contains, so a higher face weight costs more per square metre. But for an area in daily use, that extra fibre is what keeps the lawn looking full for years rather than flattening into worn tracks. Paying more up front for a denser grass in a busy garden often works out better value over the lawn's life than buying a thin grass that needs replacing sooner. The opposite is also true: spending heavily on a very high face weight for a lightly used ornamental corner is money that could be better placed elsewhere.
A few practical points when using face weight to compare:
- Compare at the same pile height. Face weight naturally rises with pile height, so only compare like for like.
- Check the units. Make sure both products quote yarn weight per square metre, not total roll weight.
- Cross-check with a sample. A high number should translate into a pile that feels dense and springs back when pressed.
Treated this way, face weight becomes a dependable shorthand for quality — not the only thing that matters, but one of the most honest single figures a supplier can give you.
Frequently asked questions
Is a higher face weight always better?
A higher face weight generally means a fuller, plusher and more durable lawn, so for heavily used areas it is usually worth paying for. For a lightly used ornamental space, a more moderate face weight can be perfectly adequate. It should be read alongside pile height, Dtex and a physical sample rather than in isolation.
What is a good face weight for artificial grass?
There is no single correct figure, because it depends on pile height and intended use. As a rule, the higher the face weight for a given pile height, the fuller and more hard-wearing the grass. Compare face weight between products of the same pile height to see which is the denser, more substantial option.
Why do some suppliers only quote total weight?
Total weight includes the backing, so it can look more impressive than face weight even when the pile is thin. Some suppliers quote it because it produces a bigger number. If only total weight is listed, ask for the face weight, which reflects the yarn alone and is a more honest measure of fullness.
