How do you check how much infill is in artificial turf?
Push a steel ruler straight down through the fibers to the backing, pinch it where the sand level sits, and read the depth. Infill should cover enough of the pile that a healthy amount of fiber still stands exposed above it. Too little infill and fibers lean over instead of standing up. TIMELESS Turf Restoration measures infill depth in every Premium Restoration on the Grand Strand.
Key takeaways
- A steel ruler pushed to the backing is the whole test. No app, no gauge, two minutes.
- Check the pet zone, the main path and the middle of the yard, not just one spot.
- Infill should cover a healthy portion of the pile, low enough that a clear amount of fiber still stands exposed as visible blade.
- A low reading in one zone does not mean the whole yard needs topping up.
The test
Push a rigid steel ruler, a wooden yardstick or tape measure works but flexes and is less precise, straight down through the fibers until it meets the backing, pinch it with your fingers right at the point where you can feel the sand level, then lift it out and read where your fingers landed. Do this in at least three spots: the busiest path, a pet zone if there is one, and a spot in the open lawn that gets little traffic, since these will read differently and that is expected.
What the number should look like
Infill is meant to fill a good part of the pile height, not all of it, so some fiber should still stand exposed above the sand; exactly how much varies by the product that was installed. The point of the test is less about hitting an exact number and more about comparing your own readings to each other, and to how the turf looked when it was newer.

What a low reading means
Too little infill leaves fiber with nothing supporting it low on the blade, so it leans over under its own weight and foot traffic and looks matted no matter how much you brush it. A path or pet zone that reads noticeably lower than the open lawn nearby is the one to top up first, rather than assuming the whole yard needs the same treatment. Pet zones in particular tend to read lower than the rest of the yard first, since concentrated foot traffic and the extra rinsing an odor routine calls for both wash a little more infill down and out over time.
What a high reading means
Infill piled too high covers more of the blade than it should, and the turf underfoot feels stiffer and the blades look shorter and stubbier than they were installed to look. Less common than running low, but it happens after repeated topping up without checking first. There is no fix for a high reading other than time and normal wear; it is not worth trying to remove infill by hand, and the depth settles back down on its own within a season or two of regular use.
When to check
A quick check twice a year, timed with the spring and fall deep clean, catches a slow drop before it shows up as matting. Also worth checking any time a path or pet zone starts looking flat sooner after brushing than it used to, since that is usually the first visible sign infill has dropped.
When to call us
If most of the yard reads low, or you are not confident reading the ruler against what your turf was built with, a measured check across the whole yard is part of every Premium Restoration, and a top-up follows the same infill pricing as anywhere else: redistribution runs $0.35 to $0.65 per square foot and new infill $0.75 to $1.50 per square foot, both detailed on our infill replenishment page and the pricing page.
