Firewood Cord Calculator
A cord is a stack of wood 4 feet high, 4 feet deep and 8 feet long. A face cord is 4 feet high and 8 feet long, at whatever depth the logs are cut, which is how most woodpiles are described.

How it works
Multiply the stack's length, height and log length to get its volume. A full cord is 128 cubic feet, about 3.62 cubic metres, so the volume is divided by that figure.
A face cord is the same stack with logs 16 inches long, about one third of a cord. Some sellers use other log lengths, so check the depth before you agree on terms.
Worked example
A stack 8 ft long and 4 ft high, with logs 16 in long, holds 0.33 cords, or 1 face cords at 16 inch logs.
Questions
How many face cords make a full cord?
About three when the logs are 16 inches long. Longer logs make each face cord bigger, so there are fewer of them.
Does the air between logs count?
The calculator measures the stack as you build it, so air gaps are included. Loosely stacked wood holds less solid wood than a tight stack.
How do I measure a pile?
Measure its length and height, and the length of the logs separately. If the pile is uneven, measure the middle and round the figure down.
