A cord of wood is a stack 4' high by 4' wide by 8' long (128 cubic feet). A "face" cord is split wood stacked the same as a full cord but the log lengths are generally in the neighborhood of 16" - 20" long (rather than 24" as in the case of a full cord). This is due to the fact that smaller fireplaces and many wood-burning stoves cannot accommodate logs 24" long.
