Let’s get started!

What Is Pile Height in Artificial Grass?

Well, Pile height just means how tall the blades of your artificial grass are — measured from the base to the tip. Simple, right?

It usually ranges from 10mm to 45mm, and trust me, that number makes a big difference.

Why? Because it affects everything — how your lawn looks, how soft it feels under your feet, and how well it holds up over time.

Here’s a quick breakdown to help you choose the right height for your turf:

Short Pile (10–25 mm):

Tidy, tough, and low-maintenance

Best for:

Medium Pile (25–35 mm):

The “just right” zone.

Best for:

Long Pile (35–45 mm):

Lush, realistic, and cushiony

Best for:

Choosing the best pile height for artificial grass isn’t just about what looks good. It is all about what works best for your lifestyle.

Whether you’re covering a small patio, a sprawling lawn, or need a custom size of artificial grass to fit an oddly shaped space, the pile height and the artificial turf roll size you choose will shape the end result.

What is the Ideal Size of Artificial Grass?

When it comes to artificial grass, “size” typically refers to two dimensions: Width and Length.

Grass Width (Roll Width)

Artificial grass rolls generally come in three standard widths: 2m, 4m, and 5m. Here’s how each is typically used:

2-Meter Wide Rolls
Ideal for smaller spaces such as balconies, patios, courtyard lawns, pet areas, or decorative sections. This size is easy to handle and perfect for tight, narrow spaces.

4-Meter Wide Rolls
The most versatile and commonly used width. Suitable for most gardens, small sports courts, play areas, and even commercial spots like smoking zones or office green areas.

5-Meter Wide Rolls
Typically considered a custom size, this width is perfect for larger areas like sports fields or grand lawns. It minimizes joins, which reduces installation time and material waste.

Custom Width Rolls
Available through select suppliers, these niche rolls are tailored for specific projects. They are less commonly stocked and typically more expensive due to their bespoke nature.

Grass Length (Roll Length)

Most factory-produced artificial grass comes in standard roll lengths of 20m or 25m, depending on market demand.

Custom Lengths
Some manufacturers can cut rolls to your desired length, especially for unique or awkwardly shaped areas. However, this usually applies to width more than length.

General Guidelines

Always order slightly more than your exact dimensions to account for measurement errors or trimming during installation.
As a rule of thumb, assume the roll might fall 6 inches short in width to ensure complete coverage, especially where seams are involved.
For indoor projects or areas with narrow access (hallways, stairwells), keep roll lengths at 15m or below to allow easier movement and handling.

Why Does Having the Right Balance Matter?

Alright, so you’ve probably heard that pile height and turf size matter, but here’s the deal: they need to work together.

It’s not just about looks. The right pile height affects how your grass feels, how long it lasts, and how easy it is to maintain.

Let me break it down for you:

Aesthetics

If you’re after that lush, realistic lawn that turns heads, go for longer pile grass. It’s really thick, soft, super realistic, and looks great in front gardens, but it can flatten with heavy use. So, I would recommend just being a little careful.

Shorter pile grass isn’t as plush, but it stays tidy, holds its shape, and handles foot traffic like a pro.

Foot Comfort

Love kicking your shoes off and feeling the grass between your toes?

Then you’ll appreciate the soft, cushioned feel of a longer pile (think 30–45 mm). It’s kind of like walking on a plush rug outside.

Shorter pile, on the other hand, is firmer underfoot. Not uncomfortable—just a bit more structured. It’s ideal for patios, balconies, or areas where you need a more solid surface to walk on.

Durability

Got a busy garden? Zooming pets, energetic kids, or frequent backyard get-togethers.

In that case, shorter to medium pile turf (20–30 mm) is your best bet. It’s tougher, more resilient, and doesn’t mind being walked (or run) all over.

Longer grass looks more gorgeous than the short/medium pile, but they are not durable enough.

Maintenance

Here’s the simple rule: shorter grass = easier upkeep. It traps less debris, bounces back faster, and generally looks good with minimal effort. Perfect if you want that low-maintenance lifestyle.

Longer grass?

It’s still easy compared to real grass, but it does need a bit more love—think brushing now and then to keep it looking fresh and upright.

So... Which Artificial Grass Custom Size & Pile Height Should You Consider Next?

See….

Every backyard is different, and how you use yours should guide the type of turf you choose.

Here’s a quick breakdown to help you pick the perfect pile height for your space and lifestyle:

For Families with Kids and Pets (25–35 mm)

Got little ones running around or pets that treat the lawn like their playground? A medium pile height is your best bet. It’s soft enough for tumbles and playtime, yet tough enough to handle daily wear. Go for dense fibres for that extra cushioned feel.

For Relaxation and Visual Appeal (35–45 mm)

Want your backyard to feel like a luxury escape? A longer pile height gives you that lush, resort-style look. It’s perfect for chill zones where aesthetics and comfort matter most.

For Sports and Active Use (10–25 mm or Sports Turf)

Turning your backyard into a workout or football zone? Stick to shorter pile turf or sports-specific grass. It’s built for action—offering better grip, more stability, and serious durability.

For Balconies, Rooftops, or Decorative Corners (10–20 mm)

In low-traffic spots like balconies or rooftop terraces, a short pile height does the trick. It’s neat, easy to clean, and brings a touch of green without the maintenance hassle.

For Office Backyards or Commercial Spaces (20–30 mm)

In professional or public areas, a medium pile strikes the right balance. It looks clean, feels comfortable underfoot, and is easy to maintain, even with heavy foot traffic.

Insider Tips for Choosing the Right Artificial Grass Pile Height

Longer Isn’t Always Better

Why it matters: Many assume that the longer the pile height, the more realistic or luxurious the grass looks. But grass over 37–40 mm can begin to flatten quickly under heavy use.

Tip: If you want a lush, upright look without constant brushing or professional upkeep, stick to a pile height between 30–35 mm for residential use.

Density Can Offset Shorter Heights

Why it matters: A shorter pile height (20–25 mm) can still feel luxurious if the grass is dense. High stitch rates and quality yarns can create a soft, full look.

Tip: For balconies, showrooms, and pet areas, go shorter—but invest in dense turf to retain that plush appearance.

The “Spring-Back” Factor

Why it matters: Artificial turf with polyethylene and polypropylene blends and structured blades like C-shaped or W-shaped yarns tend to “spring back” better after footfall.

Tip: When choosing pile height, always ask about the yarn structure and resilience, not just the length. This determines how well the turf maintains its upright position.

Check the Infill Compatibility

Why it matters: Pile height determines how much infill (sand or rubber granules) your turf will need. Too much pile height and too little infill can lead to instability and early wear.

Tip: For pile heights over 35 mm, ask your installer about infill levels and compaction methods to avoid matting and uneven wear.

Climate Influences Pile Performance

Why it matters: In hot climates, longer pile heights absorb and retain more heat, making them uncomfortable underfoot.

Tip: In warmer regions or sun-drenched gardens, choose a lighter colour blend and a pile height under 35 mm to keep surfaces cooler.

Match Pile Height to Activity Level

Why it matters: High-activity areas like schools or sports zones need shorter, denser piles (20–30 mm) to withstand wear, while garden spaces can accommodate longer pile heights.

Tip: Use different pile heights in different zones. For example, a 45 mm lush lawn in the front and a 25 mm durable grass in the kids’ play area.

Get a Sample and Step On It

Why it matters: Artificial grass feels different underfoot depending on its pile height, density, and yarn type.

Tip: Always request a sample swatch, lay it flat, and test it barefoot or with shoes. The feel will help guide the right choice more than specs alone.

FAQs

How do I choose the right pile height for my artificial grass?

Choosing the best pile height for artificial grass depends on the expected foot traffic and purpose. For gardens and lawns, artificial grass pile heights between 20 mm to 40 mm are ideal. Heavier traffic needs longer pile heights, while light use can go with shorter grass.

What artificial grass size should I pick based on foot traffic?

If you expect high footfall—kids playing, pets running, or regular use—opt for a higher artificial turf pile height. It provides better cushioning and durability, making it a suitable artificial turf height for busy areas.

Is there a difference in artificial grass sizes for indoor vs outdoor use?

Yes. For interior areas like balconies, go for short artificial grass sizes to maintain a clean, minimal look with low maintenance. For outdoor lawns or terraces where heavier use is expected, longer turf pile heights are more appropriate.

What’s the best pile height for artificial grass in an office space?

Offices should use medium to long pile height artificial grass to absorb stomping and reduce noise. For office balconies, a shorter artificial grass custom size is better suited for light, relaxed foot movement.

What’s the right artificial turf pile height for sports areas?

For heavy-duty sports like football or kabaddi, go for specialised sports turf with reinforced artificial turf pile height. These are engineered to withstand intense foot thrusts and offer extra durability.

Is a 10 to 15 mm pile height good for artificial grass?

Yes, it’s ideal if you’re looking for a neat, tidy lawn that’s easy to clean and maintain. This artificial grass size works well for light recreational use, hosting parties, and maintaining hygiene.

Should I choose a pile height of 25 mm or less for my lawn?

A pile height under 25 mm works well for aesthetic appeal, but if your lawn hosts kids and pets, a denser and slightly longer artificial turf height might offer better cushioning and safety.

What’s special about 35 mm artificial grass pile height?

A 35 mm height of artificial grass offers the perfect blend of realism, softness, and resilience. It holds up under heavy use while still looking lush and natural—ideal for both homes and businesses.

Is 45 mm the best height for artificial grass if I want a bushy look?

Yes, a 45 mm artificial grass pile height gives your lawn a bushy, natural appearance and acts as a dust barrier. However, longer turf pile heights like this may need more professional upkeep.

Which pile height is easiest to maintain—short or long?

Shorter pile heights are easier to clean and wash on your own. Longer artificial turf roll sizes or pile heights may require occasional professional maintenance to retain their lush look.

What makes AstroLondon different from other artificial grass brands?

Their turf pile heights are designed for long-term use, with built-in drainage and high-resilience fibres. AstroLondon’s artificial grass custom sizes blend green, yellow, and gold tones for a natural weathered look while offering low maintenance and high durability.
