Faux Grass Pile Height Guide (2026): The Right Blade Length for Lawns, Pets, Putting and Play
Pile height is the first spec most buyers look at, and the right one depends entirely on what the lawn is for.
Pile height is the length of the blades, measured from the top of the backing to the tip, in inches or millimetres. Short pile, under an inch, is tough and easy to clean. Tall pile, over an inch and a half, looks lush but needs more care to stay upright. Most buyers pick the tallest turf they can afford and then wonder why it looks flat a year later.
This guide gives pile height by use, in both inches and millimetres, and explains why tall turf needs more face weight. We drew on guidance from Greatmats, turf maker CCGrass, MSI and UK retailers Grass Direct and Talasey. Sources give slightly different ranges, so we show ranges, not single numbers.
What pile height is best for each use?
Shorter pile works harder; taller pile looks fuller.
| Use | Pile height | In inches | Why |
|---|---|---|---|
| Putting greens | 10 mm or less | About 3/8 in or less | A short, tight surface gives a true roll |
| Dogs and heavy traffic | Up to about 25 mm | Up to about 1 in | Resists matting; easy to pick up waste |
| Sports and active play | 20 to 25 mm | About 3/4 to 1 in | Firm, even surface for running |
| Landscape lawns | 25 to 45 mm | About 1 to 1.75 in | Natural, full look |
| Decorative, low traffic | Over 40 mm | Over about 1.5 in | Lush look where few people walk |
Grass Direct gives 10 mm or less for putting and 20 to 25 mm for households that play football. Greatmats says pile of 1 in or less resists matting. Talasey says 25 to 45 mm is the common range for lawns.
What pile height is best for a lawn? About 1 to 1.75 in (25 to 45 mm) for most front and back yards. See faux grass for backyards and front yards.
For dogs? About 1 in or less. Short pile is easier to clean and drains faster. See best faux grass for dogs.
For a putting green? About 3/8 in or less. See faux grass for putting greens.
For kids? About 3/4 to 1.25 in, with a pad underneath for falls. See faux grass for kids and playgrounds.
Why does taller turf need more face weight?
Tall blades flop unless there are enough of them packed together.
Face weight is the weight of yarn in one square yard of turf, not counting the backing. Think of it like thread count on sheets: more yarn per square yard means a fuller, denser lawn. MSI notes that turf with pile of 1 in or more needs a higher face weight to stay upright.
Why? The reason is simple physics. A long blade standing alone bends under its own weight and under feet. Packed tightly among other blades, it leans on its neighbours and stays up. CCGrass notes that pile over about 30 mm tends to lie flat if it isn't dense enough.
So when you compare tall turf, look at face weight as well as height. A 1.75 in pile with a low face weight will look flatter than a 1.25 in pile with a high one. Blade shape helps too: W and S blades spring back better than flat ones. See dense faux grass and our blade shape guide.
Why does tall artificial grass go flat? Usually because face weight is too low for the height, or because it isn't brushed. Infill and regular brushing help. See our brush guide.
What is face weight? The weight of yarn per square yard, usually in ounces. Higher means denser.
Our take: from our hands-on work building stages and backdrops with artificial grass, a dense mid-height pile around 1.25 to 1.5 in is the one that photographs fullest and recovers after people walk on it; very tall, thin turf looks lush on the roll and patchy once it's been stood on.
Short or tall pile: quick comparison
Short pile wins on care; tall pile wins on looks.
| Short pile (about 1 in or less) | Tall pile (about 1.5 in or more) | |
|---|---|---|
| Look | Neat, like a mown lawn | Lush, like an unmown lawn |
| Feel | Firmer | Softer |
| Matting | Resists it well | Needs brushing to stay upright |
| Cleaning | Easy; waste sits on top | Harder; debris hides in the pile |
| Drainage | Fast | Good, but dries slower |
| Best for | Pets, play, busy areas | Show lawns, low traffic |
Is short or long pile artificial grass better? Neither is better overall. Short pile is better for pets and busy family lawns. Tall pile is better for lawns that are mostly looked at. See short pile faux grass and tall pile faux grass.
How do you measure pile height?
Measure from the backing, not from the infill. Here's how:
- Part the blades. Push a section of blades apart so you can see the backing.
- Stand a ruler on the backing. Set the end of the ruler on the backing itself, not on any infill.
- Lift the blades upright. Brush them straight up against the ruler.
- Read the tallest blades. The tips of the main blades give the pile height. Ignore the short thatch.
How is pile height measured? From the top of the backing to the tip of the blade, with blades upright. Listings often round, so 1.37 in and 1.38 in, or 35 mm, describe the same pile.
Pile height questions
These are the pile questions buyers ask most.
Does pile height affect heat? A little. Taller, denser pile has more plastic in the sun, so it can hold slightly more heat. But colour, infill and shade matter more. See faux grass for hot climates.
Does pile height affect drainage? Not much through the backing. But tall pile holds water among the blades longer, so it can take a little longer to dry after rain. Drainage speed mostly depends on the base. See our drainage guide.
