When looking for artificial grass to buy, you've probably noticed the stitch count of each model. This might seem like one of the main deciding factors. However, as we've seen, many other qualities influence the quality of artificial grass. For example, the decitex rating, gauge, and fiber shape.
Next, we'll explain in more detail what stitches are and how they affect synthetic turf. This way, we can choose the ideal stitch count for our roll of artificial grass.
The stitches of artificial turf are the points of synthetic grass fibers that are attached to the backing .
In the artificial turf manufacturing process, the textured and untextured yarns are sewn to the backing. This is done using needles that insert the yarn into the backing and other needles that gather each yarn individually to adjust them to the desired height. This way, the turf's final appearance is visible from the surface, while each stitch is visible on the backing.
Stitch count is fundamental in determining the strength, density, and appearance of artificial turf. Generally speaking, the higher the number of stitches per square meter, the denser and more durable the artificial turf will be. However, many other factors, such as the quantity and thickness of the yarn, as well as the spacing between stitches, also determine the density and durability of synthetic turf.
How does the stitch count affect artificial turf?
Appearance
When an artificial grass model has a high stitch count, its appearance is much more natural. At first glance, it will look like realistic and neat artificial grass.
However, it's important to keep in mind that too many stitches can have the opposite effect: an overly crowded and neat surface with an unnatural appearance.
Density
The density of artificial grass refers to the number of fibers per square meter. This characteristic is closely related to the stitch count. Therefore , a higher stitch count indicates a higher density of artificial grass.
However, the thickness of the thread, the number of threads per stitch, and the height of the threads will also determine the density.
Durability
Models with a higher density and a greater stitch count offer greater resistance to foot traffic. This is because the stitches are closer together, distributing the weight more evenly across the surface. This results in greater wear resistance and a longer lifespan. Therefore, if your artificial grass will be subject to heavy foot traffic, it's preferable to purchase a model with a higher stitch count.
Touch
The higher the stitch count, the softer. The density of artificial grass with a high stitch count creates a cushioned, comfortable surface that's pleasant to walk on barefoot or to lie down on.
Maintenance and useful life
As we've already mentioned, artificial grass with a higher stitch count experiences less wear and tear and greater durability. However, it also requires less maintenance since the fibers recover more quickly and don't need to be brushed as frequently.
How is the number of stitches calculated/measured?
Artificial grass manufacturers typically measure the number of stitches per square meter. Artificial grass for decorative use can be considered to have between 16,000 and 18,000 stitches. However, if it is intended for sports or play areas, a higher number of stitches per square meter will be required.
To calculate the stitch count of a particular artificial grass model, we need to know its gauge. In the article “What is Gauge and How Does It Affect the Density and Realism of Artificial Grass?” you can find all the information about the term gauge.
For example, a 3/8″ gauge is approximately 9.525 mm. To find the number of stitches per meter of fabric, we divide by 1000 mm. The result is that for a 3/8″ gauge, there are 105 stitches per square meter.
Knowing this data, we can now calculate the number of stitches per square meter:
Stitches/m2 = Stitches in 10 cm x 10 x 105 (if the gauge is 3/8)
Manufacturers may express the stitch count as stitches/m² or stitches/ml. To help you compare different models, we'll show you how to easily convert between them
Convert from stitches per m2 to ml
If the manufacturer expresses stitches per square meter and you want to know the stitches per linear meter, you must perform the following operation:
Stitches/ml = Stitches/m2 / Number of rows per meter.
We calculate the number of lines per meter using the gauge. As we saw in the article dedicated to the gauge, for a gauge value of 3/8″, the number of lines per meter is approximately 105.
For example, if we have 18,900 stitches/m2 and 105 lines per meter, we will divide and find that this model of synthetic turf has 180 stitches per linear meter.
Convert stitches per ml to m2
If the manufacturer provides us with the number of stitches per linear meter in the product's technical specifications and we want to know the number per square meter, we just have to do the reverse process.
Stitches/m2 = Stitches/ml x Number of rows per meter.
For example, in the case of having 120 stitches per linear meter and a gauge of 3/8. We will multiply the 120 stitches by the 105 lines and we will obtain that the model has approximately 12,600 stitches per square meter.
Table of correspondences between stitches/m2, stitches/ml and stitches/10cm
Below, we have included a table comparing the different ways of expressing stitch counts in the technical specifications of artificial grass products.
| Stitches 10 cm | Stitches ml | Stitches per m2 |
|---|---|---|
| 15 | 150 | 15.750 |
| 16 | 160 | 16.800 |
| 17 | 170 | 17.850 |
| 18 | 180 | 18.900 |
| 19 | 190 | 19.950 |

| 21 | 210 | 22.050 |

Ideal stitch count for good artificial grass
To choose the right stitch count for your artificial grass, it's important to consider its intended use , foot traffic , and your budget . As mentioned earlier, artificial grass for decorative purposes typically has between 16,000 and 18,000 stitches per square meter. This stitch count ensures optimal density, a pleasant feel, and an attractive appearance.
If we choose a synthetic turf with fewer stitches, we'll have a lawn with less durability and less resistance to foot traffic. Conversely, if the stitch count is excessive, the appearance will be less natural.
The optimal number of stitches will depend on the use of the artificial turf.
Low traffic
If the artificial grass is to be installed in a home with low foot traffic, the optimal stitch count is between 14,000 and 16,000 stitches per square meter. This stitch count will still provide a very attractive appearance and a soft feel underfoot.
Heavy traffic
If the area covered with artificial grass will experience heavy traffic , we can choose a model with a higher stitch count. Between 16,000 and 20,000 stitches will be perfect for this use. This will provide the ideal density and durability for gardens, patios, or public areas.
Other factors that influence the quality of artificial turf.
As we've seen before, the quality of artificial turf depends on many factors. The stitch count is one of them, but it also depends on:
- Decitex. A higher decitex value indicates greater resistance and durability of the artificial grass. However, we must also consider the intended use of the artificial grass to choose a balanced decitex value. If you want to learn more about decitex, don't miss our article "Decitex Explained: How to Measure Yarn Quality in Artificial Grass".
- Fiber Material. Polyethylene fibers are stronger and more durable than polypropylene fibers. However, the latter are less expensive. If you want to learn more about fiber materials, be sure to read the article “What are Polyethylene (PE) and Polypropylene (PP) and Why Do They Matter?”
- Filament shape. The shape of the artificial grass fibers gives each model specific qualities. To learn more about them, we recommend our article “Choose the Perfect Grass: A Complete Guide to Filament Shapes and Their Benefits.”
Furthermore, artificial grass has special treatments that make it fire-resistant. This is essential since items like barbecues, which can cause sparks or flames, are often placed on it. It also has sun-protective treatments to prevent fading from the sun.
The warranty for each artificial grass model varies. On our website, we offer products with warranties ranging from 4 to 10 years.
In conclusion, the stitch count of synthetic turf is an important factor when choosing artificial grass for your garden, balcony, patio, or terrace. A higher stitch count generally means a better appearance, greater durability, and a softer feel. However, you should consider how you intend to use the turf to select the optimal stitch count.
