There is no single grass height that works for every non-infill artificial turf application. In practice, the right pile height depends on the use scenario, tuft density, yarn Dtex, backing system, cushioning layer, drainage design, and expected traffic.

As a general reference, 25–35 mm is common for residential gardens and landscaping, while 20–25 mm can be practical for balconies and rooftops. Children's areas and pet areas often fall around 20–30 mm. Sports applications require a more system-based approach, where pile height is considered together with tuft density, yarn construction, shock pad and base.

Quick Reference: Choosing Pile Height by Application

These ranges should be treated as selection references rather than universal specifications. The final specification should be based on the actual turf system and project requirements.

Why Pile Height Should Not Be Selected in Isolation

1. Pile Height and Tuft Density Work Together

In traditional infill artificial turf, sand and rubber or other infill materials help support the synthetic fibers. A non-infill system does not have this loose support layer.

Instead, the upright performance of the turf depends more heavily on:

• Tuft density
• Yarn Dtex and yarn geometry
• Fiber stiffness and resilience
• Primary and secondary backing stability
• Cushioning system
• Installation quality

This creates an important relationship:

The taller the pile, the more important the overall structural design becomes.

A tall pile with insufficient density may be more susceptible to flattening and can feel less stable under repeated traffic. Increasing pile height alone therefore does not necessarily improve performance.

For non-infill turf, a moderate pile height combined with appropriate density and yarn construction can often provide a more balanced solution.

How Pile Height Affects the User Experience

Visual Appearance

For landscaping, increasing pile height generally creates a fuller appearance. However, excessive height can make a lawn look less tidy and may make brushing and cleaning more demanding.

Foot Feel and Resilience

Pile height contributes to the perceived softness of artificial turf, but it is only one component.

Two products with the same 30 mm pile height can feel very different because their:

• yarn Dtex,
• tuft density,
• fiber profile,
• backing,
• cushioning layer

may be completely different.

Drainage

Pile height itself does not determine drainage performance.

The drainage capacity of a complete turf system depends on the fiber structure, backing perforation, sub-base, drainage layer and overall installation design. Longer fibers can retain more surface moisture, but a well-designed backing and base system can still provide effective drainage.

Cleaning and Maintenance

Shorter turf is generally easier to brush, rinse and remove debris from. This can be particularly useful in:

• pet areas,
• children's play spaces,
• balconies,
• high-use residential areas.

For landscaping, however, an excessively short pile may sacrifice some of the visual fullness that homeowners expect.

Cost

Pile height and yarn weight affect material consumption, but higher pile does not automatically mean better value.

A more meaningful comparison is the complete specification:

Pile height + tuft density + yarn Dtex + backing + drainage + cushioning + warranty + testing

Recommended Pile Height by Application

Residential Gardens and Landscaping: 25–35 mm

For home gardens, terraces and general landscaping, 25–35 mm is a useful starting range.

A 25–30 mm product can offer relatively easy maintenance, while around 30–35 mm can create a fuller visual appearance.

For non-infill landscaping turf, it is particularly important to check density and yarn construction because there is no loose infill layer supporting the fibers.

Recommended focus:

• 25–35 mm pile height
• Appropriate tuft density
• UV/weathering performance
• Drainage performance
• Fiber resilience
• Backing stability

Rooftops, Balconies and Terraces: 20–25 mm

For elevated applications, pile height is only one part of the equation.

The project should also consider:

• structural load,
• drainage,
• waterproofing,
• wind exposure,
• installation method,
• maintenance access.

A 20–25 mm pile can be practical because it reduces material volume and is relatively easy to maintain.

However, artificial turf should not be selected solely according to building load. The weight of the complete system, including any cushion or underlay, must be checked against the structural design.

Children's Areas and Kindergartens: 20–30 mm

For children's areas, pile height should not be treated as a direct indicator of safety.

The critical question is whether the complete surface system achieves the required impact attenuation, vertical deformation, drainage and other safety requirements.

Depending on the jurisdiction and project type, standards such as EN 1177 and applicable national playground or sports-surface requirements may be relevant. For Chinese school sports facilities, the applicable Chinese mandatory standards should be checked against the latest edition and the specific project.

In other words:

A thicker or taller artificial turf product is not automatically a safer children's surface.

The turf, shock pad and base need to be evaluated as one system.

Pet Areas: 25–30 mm

For dogs and other pets, a 25–30 mm pile can provide a reasonable balance between appearance, comfort and maintenance.

Shorter turf can make it easier to:

• remove pet hair,
• rinse the surface,
• remove organic debris,
• inspect the surface.

For pet applications, drainage and cleaning design can be more important than adding several millimeters of pile height.

What About Sports Applications?

Sports turf is where the idea of a universal "ideal grass height" becomes particularly misleading.

For football and other sports, the specification should be based on the complete sports-surface system, not simply the pile height.

For example:

Turf → shock pad → base → drainage → installation

all influence the final playing characteristics.

For certified football turf, FIFA's current Quality Programme evaluates multiple characteristics, including player-surface interaction, ball-surface interaction, durability, weather resistance and other performance requirements. Non-filled systems are also part of the current FIFA testing landscape.

Therefore, a manufacturer should provide a complete system specification and test documentation rather than simply saying that a certain pile height is "professional."

Key Technical Parameters to Compare

This is why comparing two products simply by saying "both are 30 mm" can be misleading.

A 30 mm / high-density system and a 30 mm / low-density system may have substantially different performance.

How to Specify Non-Infill Turf More Professionally

Instead of asking a supplier:

"How many millimeters is your artificial grass?"

A better procurement specification is:

Application → pile height → tuft density → yarn Dtex/profile → backing → drainage → cushion → base → testing

For example, a residential project could request:

30 mm non-infill landscape turf + specified tuft density + specified yarn Dtex + stable backing + documented drainage performance + UV/weathering test data.

For a sports project, the specification should go further and include the required playing-surface performance and applicable certification/testing requirements.

Domestic Standards: How Should They Be Applied?

For projects in China, standards such as GB/T 20394 and GB 36246 may be relevant depending on the application. However, they should not be treated as interchangeable.

For example:

• Sports artificial turf: product specifications and sports-surface requirements should be checked against the applicable edition of GB/T 20394 and project specifications.
• School sports facilities: applicable mandatory requirements under GB 36246 should be verified.
• Playground applications: relevant playground-surface requirements should also be considered.
• Landscape applications: product selection should focus on the manufacturer's technical specification, applicable material/environmental requirements and third-party test documentation.

For international projects, relevant EN, DIN, ASTM, FIFA or other project-specific requirements may apply. The exact standard should always be matched to the application and destination market.

VivaTurf Non-Infill Artificial Turf: Choosing the System, Not Just the Grass Height

For projects evaluating non-infill artificial turf, VivaTurf can be included among the manufacturers worth evaluating, particularly when the project requires a combination of non-infill technology, product specifications and international testing experience.

Rather than recommending one universal pile height, VivaTurf's non-infill solutions can be selected according to the application—for example, landscaping, residential gardens, children's areas or sports facilities—with the pile height matched to tuft density, yarn construction, backing and the overall installation system.

For buyers, the more useful approach is to request the specific product datasheet, test reports and system installation requirements for the model being considered. This makes it possible to compare products on measurable technical parameters rather than relying on pile height alone.

Final Takeaway

For most non-infill artificial turf projects, 25–35 mm is a practical reference range for residential landscaping, while 20–25 mm may suit many balconies and rooftop applications. Children's and pet areas often fall around 20–30 mm, subject to the requirements of the complete surface system.

But the most important principle is:

Do not choose non-infill artificial turf by pile height alone.

The right combination of pile height + tuft density + yarn Dtex + backing + drainage + cushioning + installation determines whether the turf is actually suitable for the intended application.
