How to Read an Artificial Turf Spec Sheet (and Spot Padded Numbers)
Walk through every line of a typical turf spec sheet with an example, learn what good values look like, and catch the common ways numbers get inflated.
On this page
This guide is for anyone comparing two or more quotes or products and wanting to know which numbers matter and which are noise. We use an example spec sheet, explain each line and show the arithmetic that exposes inflated or missing figures.
What does a typical turf spec sheet look like?
Here is an illustrative sheet for a mid-range landscape product. The values are typical, not from any specific manufacturer.
| Line item | Example value |
|---|---|
| Yarn type | PE monofilament, W profile + PP texturized thatch |
| Yarn Dtex | 11,000 (blade) / 5,000 (thatch) |
| Blade thickness | 300 microns |
| Pile height | 1.5 in (38 mm) |
| Gauge | 3/8 in |
| Stitch rate | 16 per 4 in |
| Face weight | 62 oz/sq yd |
| Total weight | 90 oz/sq yd |
| Primary backing | Double layer woven polypropylene |
| Secondary backing | Polyurethane coating |
| Perforations | 5/16 in holes on 4 in centers |
| Drainage rate | 30+ in/hr |
| Tuft bind | 10 lbf (ASTM D1335) |
| UV stabilization | UV stabilized, tested to stated hours |
| Lead content | Below detection, test report available |
| Flammability | Passes pill test (16 CFR 1630) |
| Roll widths | 15 ft and 7.5 ft |
| Warranty | 10 years limited, fading and fiber degradation |
Line by line: the yarn
Yarn type. Look for the polymer (PE, PP, nylon), construction (monofilament or slit film) and both components if the product has thatch. "Premium blend" without polymers is a red flag. See fiber types.
Yarn Dtex. Mass in grams per 10,000 meters of the yarn bundle. Landscape blades are commonly 8,000 to 16,000. Check whether the number is per bundle or per strand, and whether it covers blades and thatch together.
Blade thickness. Often in microns. Values around 250 to 400 are common for landscape PE; thicker is stiffer. Many sheets omit it; ask.
Pile height. Straight blade length above the backing. If there are two heights, both should be listed. See pile height.
Line by line: construction
Gauge. Distance between tuft rows. 3/8 and 1/2 inch are common residential gauges; 5/8 inch and wider look sparser.
Stitch rate. Tufts per unit length along a row. Watch the unit: per 4 inches, per 10 cm and per meter all appear. Convert to stitches per inch before comparing.
Face weight vs total weight. Face weight is yarn above the backing; total weight includes backing. The difference is usually 20 to 35 oz. If only "weight" is shown, assume total. Our face weight and density guide explains how these relate.
Primary and secondary backing. Primary is the woven fabric; secondary is the coating (latex or polyurethane). See backing.
Perforations. Hole size and spacing for hole-punched products, or "fully permeable" for porous designs.
Line by line: performance and compliance
Drainage rate. Usually inches per hour through the turf in a lab. It describes the turf alone, not your yard. A base or soil that drains slowly will be the bottleneck. See drainage rates explained.
Tuft bind. Force to pull a tuft, ideally with the test method named (ASTM D1335). Our targets: 8 lbf minimum for decorative, 10 lbf or more for family and pets.
UV stabilization. Should reference a test method or hours of accelerated exposure, not just "UV protected." A warranty that names fading is a useful backstop.
Lead content. Look for a lab result, ideally reported as below detection or well under the 100 ppm limit the CPSC applies to lead in children's products. "Lead-free" with no test report is a claim, not a result. Background is in safety and health.
Flammability. Many products cite the methenamine pill test used for carpets (16 CFR 1630, ASTM D2859). Passing means a small ignition source did not spread fire beyond a set distance; it does not mean the turf is fireproof.
Warranty. Check years, whether it is prorated, what it covers (fading, fiber loss, backing failure), and what voids it (improper install, pets, reflective window damage). See warranties.
How do you spot padded numbers on a spec sheet?
Padded sheets are rarely false outright. They pick the most flattering measurement, unit or definition. Watch for these patterns:
- Total weight presented as face weight. If the "weight" is 80 to 100 oz on a budget product, it is probably total weight.
- Stitch rate in big units. "160 stitches" sounds dense until you see it is per meter (about 4 per inch).
- Dtex that adds blade and thatch. A combined figure looks high but much of it is cheaper thatch.
- Tallest blade quoted as pile height on dual-height products.
- Drainage rates without method. Very high numbers with no test description, or rates measured with no backing coating at all.
- Unnamed tests. "Lab tested," "UV tested," "pet safe" without a method, value or report.
- Missing lines. No tuft bind, no blade thickness, no gauge. Absence usually means the value is unremarkable.
How do you cross-check a spec sheet?
The numbers should be consistent with each other. Our consistency check (a rough model, not a lab test) uses the face weight formula to see if the claimed face weight is plausible given gauge, stitch rate, Dtex and pile height.
A sheet that passes this check, names its test methods and lists tuft bind and blade thickness is usually trustworthy. A sheet whose face weight is far above what the construction can produce should be treated with caution.
A spec sheet checklist for comparing quotes
- Polymer and construction named for blade and thatch.
- Dtex stated with clarity on bundle vs strand.
- Pile height for each blade height.
- Gauge and stitch rate with units.
- Face weight and total weight both listed.
- Coating type named (latex or polyurethane).
- Tuft bind with test method, 8 to 10 lbf or more.
- Drainage design and rate.
- UV test reference.
- Lead test result.
- Warranty terms in writing.
Bring this checklist to getting quotes, and when you have narrowed the field, score the finalists with the choosing the right turf framework or the turf selector.
Frequently asked questions
Why do two retailers list different specs for the same turf?
Resellers often rename products and copy specs selectively, sometimes rounding up or listing total weight as face weight. Production lots can also change over time. Ask each seller for the manufacturer's current spec sheet, ideally with the manufacturer name and product code, and compare those documents directly rather than retailer web listings.
Is a higher drainage rate always better?
Beyond a point, no. Rain falls on most of the US at well under 2 inches per hour, so a turf rated at 30 inches per hour already passes ordinary storms faster than they fall, provided the base can accept the water. Higher rates help where liquid is concentrated, such as dog urine spots. For lawns without pets, base and soil drainage matter more.
What if the spec sheet has no tuft bind number?
Ask the seller for it, with the test method. If they cannot provide it, assume it is not a selling point for that product. Tuft bind is one of the best predictors of how long tufts stay anchored in traffic zones, so its absence should push a product down your list, especially for pets, play areas and paths.
Should spec sheets list heat or temperature data?
Some do, especially for products with heat-reflective pigments, but there is no single standard test used across residential turf products. If a sheet claims a temperature reduction, check whether it states the test conditions, the comparison product and the ambient temperature. Without those, the figure cannot be compared to other products.
