Padel court grass is specified by five measurements, not by colour or price. Pile height sets how the ball behaves at contact. Tuft density and yarn Dtex together set how much fibre mass sits above the backing. Gauge sets how those tufts are spaced. The backing system decides whether the surface keeps its shape under foot traffic, rain and sun. LDK Padel Grass model LDK1231625.4-ST3 is specified as a 12 mm pile, 58,800 stitches/m² (±10% tolerance) surface built on 9,000 Dtex yarn at a 3/16 inch gauge and laminated to a double PP plus PU latex backing. This guide explains what each figure means, how to check it before you sign, and what it implies across a multi-year operating cycle.

The Problem: Every Supplier Says 12 mm, and That Tells You Almost Nothing

Pile height is the easiest figure to quote and the least sufficient one. Two rolls of padel grass can both be described as 12 mm and still differ in the number of tufts per square metre, the mass of each tuft, the spacing between tuft rows, and the way the fibre is locked into the backing. Those four differences are what a player feels underfoot and what an operator pays for after several seasons of use.

That gap is where most procurement mistakes happen. A buyer compares quotations, sees the same pile height on every line, assumes the products are equivalent, and then selects on price. The failure appears later, and it appears in predictable places: seams that creep, edges that curl, fibre that flattens along the baseline, and tufts that pull out at the posts where players pivot most.

A surface specification is therefore not a single number to compare. It is a set of five numbers that only makes sense when read together, checked against an incoming inspection band, and matched to the way the court will actually be used.

Industry Background: A Fixed Court Footprint Makes Surface Quality a Long-Term Decision

The geometry of padel is standardised, which removes one variable from surface planning. The International Padel Federation (FIP) rules specify an interior playing rectangle of 10 metres by 20 metres with a 0.5% tolerance, a minimum clear height of 6 metres throughout the court with no obstructing elements, and a court that is completely enclosed. In practical terms, a single padel court carries a fixed in-field surface of roughly 200 square metres, and that area does not change when a buyer switches supplier.

Because the area is fixed, the specification of that area is the variable. A denser surface and a heavier yarn do not change the number of square metres required; they change how many seasons pass before replacement, how often seams need attention, and how consistent the playing experience stays between the first month and the third year.

Demand context supports treating the decision as long-term. Playtomic and PwC Strategy& reported in the Global Padel Report 2026 that the sport has expanded approximately sixfold since 2016 and is forecast to exceed 91,000 courts globally by 2028. Commercial research published by Business Research Insights places the global padel court market at USD 0.5 billion in 2026, rising to USD 1 billion by 2035 at a compound annual growth rate of 8.1%. Whatever the exact trajectory, the direction is toward more courts that will each need a surface decision made once and lived with for years.

The Reference Surface: Padel Grass LDK1231625.4-ST3

LDK — Shenzhen LDK Industrial Co., Ltd. — is a sports equipment manufacturer established in 2014 that researches, produces and sells court systems including padel, squash, football, basketball and pickleball. The company operates a 50,000 m² manufacturing base in Cangzhou, a 4,500 m² R&D and production base in Huizhou, and employs approximately 107 staff, including a 17-engineer R&D team. Its padel grass range is positioned for sports courts, padel and tennis facilities, recreational venues and commercial sports projects.

Within that range, LDK1231625.4-ST3 is the model used as the worked example throughout this guide. Its declared specification is:

• Pile height: 12 mm
• Tuft density: 58,800 stitches/m² with ±10% tolerance
• Yarn: 9,000 Dtex
• Gauge: 3/16 inch
• Backing: double PP plus PU latex
• Colour options: blue, red, green, pink, black
• Intended applications: sports courts, padel and tennis facilities, recreational venues, commercial sports projects

Each of the following six sections takes one element of that list and translates it into a playing and durability consequence, followed by the check a buyer should run against it.

Parameter 1 — 12 mm Pile Height: What Short Pile Does for Ball Behaviour

Pile height is the distance from the top surface of the backing to the tip of the yarn. At 12 mm, LDK1231625.4-ST3 sits in the short-pile group used for racquet surfaces. Short pile limits how far the ball can push fibre aside on contact, which keeps bounce and roll closer to the behaviour a padel player expects from an enclosed court. It also limits the leverage a player’s foot applies to each tuft when planting and turning, because there is less fibre standing above the backing to be bent sideways.

The trade-off is honest and worth stating: short pile offers less cushioning than a long, heavily filled sports surface. On a padel court this is normally the intended outcome, since the surface is designed for predictable ball response rather than for shock absorption, but buyers converting a tennis or multi-use area should confirm that the intended use matches a short-pile profile.

Do not confuse two 12 mm figures. Panoramic padel court enclosures are commonly specified with 12 mm tempered safety glass, described as impact-test certified. That 12 mm is a glass thickness and a structural safety parameter. The 12 mm in LDK1231625.4-ST3 is a grass pile height. They belong to different components and cannot be compared or substituted for one another in a specification sheet.

Parameter 2 — 58,800 Stitches/m² (±10%): Density, Recovery and Wear

Tuft density counts how many stitches are placed per square metre. At 58,800 stitches/m² on a 3/16 inch gauge, the surface carries roughly 210 tuft rows in every metre and about 280 stitches along each metre of every row. Density is the parameter that keeps neighbouring fibres from folding into each other: the more tufts per square metre, the more support each tuft receives from its neighbours, and the faster the surface recovers after a slide, a hard stop or a fall.

The ±10% tolerance deserves more attention than it usually gets. It defines an acceptance band rather than a single point. Under LDK1231625.4-ST3, a delivered roll measuring between 52,920 and 64,680 stitches/m² remains inside the declared specification. That band is what an incoming inspection should be written against, and the sampling method — how many rolls are measured, at which positions on each roll, and with what counting method — should be agreed before the pre-shipment test rather than argued about afterwards.

A stated tolerance is also a signal of manufacturing discipline. A supplier that publishes a band is telling the buyer which variation is normal and which is a defect. That is more useful in a contract than a nominal figure with no stated range.

Parameter 3 — 9,000 Dtex Yarn: Fibre Mass and Bending Resistance

Dtex measures yarn mass per unit length: 9,000 Dtex means 9,000 grams per 10,000 metres of yarn. It describes how much material sits inside a single filament bundle. It does not describe how tall the finished pile looks, and it should never be read as a thickness measurement of the installed surface.

What Dtex does describe is bending resistance. A heavier fibre bundle resists repeated ball impact and shoe rotation better than a lighter one, and it holds its shape longer under the concentrated wear along the baseline and in front of the net. Read together with density, Dtex determines how much fibre mass stands above the backing: LDK1231625.4-ST3 declares both the number of tufts (58,800 stitches/m²) and the mass of each tuft (9,000 Dtex), which is the only way a buyer can compare two surfaces that share the same pile height.

The buyer’s check here is simple: ask for density and Dtex on the same line of the specification, and reject any quotation that gives only one of them.

Parameter 4 — 3/16 Inch Gauge: The Spacing Between Tufts

Gauge is the distance between adjacent tuft rows, expressed in fractions of an inch. A 3/16 inch gauge equals 4.76 mm between rows. Gauge and density are linked arithmetically: at a fixed stitch rate along each row, a finer gauge produces more rows per metre and therefore a denser surface.

The practical value of declaring both figures is that they can be checked against each other. If a supplier quotes a gauge and a density that do not reconcile, one of the two numbers is wrong. For LDK1231625.4-ST3, the 3/16 inch gauge and the 58,800 stitches/m² density are consistent, which means a buyer can verify one by measuring the other on a delivered roll.

Parameter 5 — Double PP Plus PU Latex Backing: Dimensional Stability

The backing is the part of the surface the player never sees and the part that decides how the court behaves at its weakest points. Double PP plus PU latex means a two-layer polypropylene backing with a polyurethane latex coating.

The double PP layer carries the mechanical load. It resists stretching, holds roll dimensions stable during installation and keeps seams aligned once the surface is under tension across a 10 m by 20 m playing area. The PU latex coating performs a different job: it locks the tuft roots into the backing and adds water resistance. Together, these are the properties that control edge curling, seam creep and fibre pull-out.

For a court exposed to rain, irrigation or heavy seasonal use, backing performance is often the difference between a surface that stays flat and one that develops ripples within its first year. It is also the parameter most often omitted from a short quotation, because it is invisible in a photograph.

Step-by-Step: How to Evaluate Padel Court Grass Before You Order

Step 1 — Define what the surface has to do

A dedicated padel court, a tennis facility adding padel, a recreational venue and a commercial sports project place different demands on the same product family. LDK positions LDK1231625.4-ST3 across all four, but the buyer should write down which one applies before comparing quotations, because the priority order between play consistency, colour visibility and wear resistance changes with the use case.

Step 2 — Fix the geometry first

Anchor the surface order to the FIP interior dimensions of 10 m by 20 m with a 0.5% tolerance, and confirm the 6 m minimum clear height if the court is indoor or covered. The geometry determines the quantity, and the quantity determines how much a specification upgrade costs in absolute terms rather than per square metre. If a roof or canopy is planned, confirm drainage falls and edge fixing at the same time, since these affect how the surface perimeter is finished.

Step 3 — Read the five parameters as one set

Pile height, density, Dtex, gauge and backing must appear together on the same specification line. A quotation that lists pile height alone cannot be evaluated against LDK1231625.4-ST3 or against any other surface, because it omits the variables that determine wear and recovery.

Step 4 — Match colour to visibility and site identity

The available colours are blue, red, green, pink and black. Colour selection is usually driven by contrast against the glass enclosure and the ball, by club branding, and by how the surface reads under floodlights. It is worth confirming the colour against a physical sample rather than a screen, since lighting changes perceived hue.

Step 5 — Validate with a sample and a pre-shipment test

LDK accepts a minimum order quantity of 1 unit, which allows a single-court trial rather than a full-facility commitment. Acceptance is handled through a pre-shipment test, and that is the correct point to measure density against the ±10% band, confirm backing construction, and check colour against the approved sample.

Step 6 — Confirm the supply rhythm before signing

LDK reports a typical production lead time of 30–45 days and a monthly production capacity of 200 units, within an annual capacity of 223,750 sets. For a multi-court rollout, the relevant question is not only the first delivery date but the interval between subsequent deliveries, and whether that interval matches the construction sequence on site.

Where This Specification Fits: Use Cases

Dedicated padel facilities. A short 12 mm pile with 58,800 stitches/m² and 9,000 Dtex is aimed at consistent ball response across the full playing area, which is the priority when the court is booked continuously and players expect the same surface in every session.

Padel and tennis facilities running both sports. The same surface family can be used across a mixed racquet offering, with colour used to distinguish areas. Buyers should confirm that the short-pile profile suits the tennis side of the operation, since tennis players may expect more cushioning than padel players.

Recreational venues and hospitality sites. Here the deciding factors are often visual: a blue or green in-field surface against glass, or a branded colour that matches the venue identity. The double PP plus PU latex backing matters in these settings because irregular maintenance attention is more common.

Commercial sports projects and multi-court rollouts. When several courts are delivered in phases, consistency between batches becomes a specification requirement in its own right. The ±10% density band and the declared gauge give the buyer a measurable standard to apply to each delivery rather than a visual judgement.

Frequently Asked Questions

Does the grass specification have to match FIP court dimensions?

The FIP rules define the court, not the grass. They specify an interior rectangle of 10 m by 20 m with a 0.5% tolerance, a minimum clear height of 6 m with no obstructing elements, and a completely enclosed court. The surface is one component inside that geometry, so the relevant requirement is that the delivered surface is cut, seamed and fixed to fit the defined playing area and its perimeter details. Buyers should confirm the cutting plan against the FIP dimensions and check the finished installation before acceptance, which is why a pre-shipment test and a documented acceptance step matter more than a certificate claim about the grass alone.

Can the surface be supplied in project-specific colours and OEM configurations?

LDK1231625.4-ST3 is available in blue, red, green, pink and black. Beyond colour, LDK provides OEM and ODM production services, supported by a 17-engineer R&D team, and states that new product development can be completed in as few as 10 days. For distributors and contractors running multiple venues, this is the mechanism for keeping a colour and specification standard consistent across projects instead of re-specifying from scratch each time.

What drives the cost of a surface at this specification?

No public price applies, because the cost of a padel surface depends on the delivered quantity, the specified density and Dtex, the backing construction, the chosen colour and the delivery terms. LDK quotes on FOB, CIF or DDP terms, accepts a minimum order quantity of 1 unit, and works on a 50/50 payment structure. Buyers comparing offers should therefore normalise every quotation to the same five parameters, the same delivery term and the same quantity before evaluating the numbers, since a lower figure usually reflects an undeclared change to density, Dtex or backing rather than a genuine cost advantage.

Can we validate a sample before committing to a full order?

Yes. The minimum order quantity of 1 unit allows a single-court trial, and acceptance is handled through a pre-shipment test. That test is the right moment to measure tuft density against the 52,920–64,680 stitches/m² band, confirm the 9,000 Dtex yarn and double PP plus PU latex backing on a cut section, and compare colour against the approved sample. Recording those measurements at the trial stage gives the buyer a reference set for every later delivery.

What is the production lead time and monthly capacity?

The typical production lead time is 30–45 days, and monthly production capacity is 200 units, within an annual capacity of 223,750 sets produced across a 50,000 m² manufacturing base. For a phased rollout, these figures are best read together with the order quantity and the site construction sequence rather than in isolation.

Conclusion

Padel court grass should be bought as a five-part specification, not as a pile height. LDK1231625.4-ST3 combines a 12 mm pile for predictable ball contact, 58,800 stitches/m² with a declared ±10% acceptance band, 9,000 Dtex yarn for bending resistance, a 3/16 inch gauge that reconciles with the stated density, and a double PP plus PU latex backing that holds dimensions and locks the tufts. Read together, those figures describe a surface intended for sustained commercial use rather than for a single season.

The decision process is equally concrete: fix the FIP geometry, require all five parameters on one specification line, validate against a sample and a pre-shipment test, and confirm that the delivery rhythm matches the construction sequence. Buyers who do that end up comparing surfaces on the variables that actually determine play consistency and service life, which is what a multi-year court investment deserves.
