How this artificial turf material calculator works
Every quantity starts from the area you are covering. The calculator takes that area and figures four things an installer orders separately: the turf itself, the roll length it comes on, the infill that weighs the blades down, and the crushed-rock base underneath.
Turf is ordered as the covered area plus a waste allowance, because a real job needs offcuts for seams, angles, and matching the pile direction across pieces. The roll length is that order area divided by the roll width you pick. Infill is your area multiplied by a spread rate, then rounded up to whole bags. Base rock is your area at the depth you choose, converted from a volume into cubic yards and then tons.
The output is a set of planning quantities, not a final order. Yard shape, seam layout, and drainage all change the real amounts. Use these numbers to size your order and to sanity-check a supplier list, then confirm the final quantities before you buy.
