Pile height refers to the length of your turf fibers. This is generally an indicator of how your artificial grass will hold up to high foot traffic. The shorter your turf’s pile height is, the more durable it will be. Longer blades of grass provide a more luxurious look and feel, but they can become matted and unsightly if overused. It’s important to strike the right balance to achieve your desired look while selecting a product that can withstand the appropriate amount of foot traffic.
