How deep the stack is — typically the length of the cut logs, e.g. 16 in = 1.33 ft.
Optional — your local going rate for a full cord, to value the stack.
Multiply the stack's length, height, and depth (in feet) to get its volume in cubic feet, then divide by 128 — the cubic feet in a full cord — to find how many cords it holds. Enter your local price per cord to value a stack or check a seller's quote. Stacking tightly and measuring honestly matters: loose or short stacks hold less than they look.
Heating with your own wood is one reason homesteaders factor a woodlot into their land plan — see our land needed calculator to size one in.
A full cord is 128 cubic feet of stacked wood — most commonly a stack 4 feet high, 8 feet long, and 4 feet deep. This calculator multiplies your stack's length, height, and depth to get the volume, then divides by 128 to find how many full cords it holds.
A full cord is the full 128 cubic feet. A 'face cord' (or rick) is one row 4 feet high and 8 feet long, but only as deep as the logs are long — often 16 inches, which is about a third of a full cord. Sellers sometimes quote face cords, so always confirm the depth before comparing prices.
As a rough guide, 3 to 6 full cords heats a typical home for a winter when wood is the main heat source — more in a cold climate or a leaky house, less in a small, well-insulated one. Hardwoods like oak and maple pack far more heat per cord than softwoods.
