What is pile height?

Pile height is the length of the blades, measured from the backing to the tip. It’s expressed in millimetre (mm) and ranges from less than 10 mm to over 50 mm. For lawns and gardens, pile heights between 25 mm and 40 mm are most common.

Finding the right pile height for your project all depends on the intended use. How much foot traffic are you expecting? For example, contact sports, such as football or rugby, require different artificial grass solutions than untrodden home lawns. Aesthetics can also be a gamechanger: what should your artificial grass look like? Some prefer short, neat grass, while others want longer, lush-looking artificial grass.
