How Much Concrete for a 16×16 Patio?

A 16×16-foot patio poured 4 inches thick needs about 3.32 cubic yards of concrete (roughly 150 eighty-pound bags), with a small waste allowance. For a pour this size, ready-mix delivery is usually cheaper and easier than mixing bags. The calculator below is pre-filled with these numbers — change the thickness or dimensions to match your project.
