A face cord is 1/3 of a full cord where the stack is 4' tall and 8' long with peices of firewood stacked tightly together that are 16 inches long.
Height = 4 feet, Length = 8 feet, and width = 16 inches
A cord of wood is defined as a tightly stacked rectangle measuring 4' tall x 4' wide x 8' long, or 128 cubic feet (4 x 4 x 8 = 128). The usual configuration is three rows of 16" lengths, each row measuring 4' tall x 8' long.
Measurement Canada recommends that the use of the cord as a unit of measurement be discontinued, as it is largely misunderstood and often misused by people selling firewood. For example, some sellers use illegal terms such as "face cord", "stove cord", "apartment cord", "furnace cord" and "short cord" to refer to a quantity smaller than 128 cubic feet. Such terms frequently lead to confusion about the actual quantity of firewood being sold.
To avoid any confusion about the amount of firewood purchased or sold, Measurement Canada recommends the use of the stacked cubic metre when purchasing or selling bulk firewood.
