Frequently asked questions
A full cord is 128 cubic feet, traditionally a stack 8 ft long, 4 ft high and 4 ft deep. That stack is exactly one cord.
Multiply the stack's length, width and height in feet and divide by 128. An 8 × 4 × 4 ft stack is one cord.
A face cord is 8 ft long and 4 ft high but only as deep as the log length, so it is usually a fraction of a full cord.
A cord assumes neatly stacked wood. Loosely thrown wood has more air gaps, so it holds less actual wood per cubic foot.
