I wondered to and found this:
A rick of firewood is a firewood measurement used to describe a quantity of wood. Unlike a cord of firewood which is 128 cubic feet, a rick or face cord is not a consistent measurement, so it can vary from place to place.
The biggest problem with a buying a rick of wood is the fact that you don't know exactly how much wood you are getting. The length of the logs dictate how much wood you get.
Generally speaking if the logs are cut 16 inches long and are stacked 4 feet high by 8 feet long, a rick will be 1/3 of a cord.
If these same logs were cut 24 inches long, the rick would equal 1/2 cord. So the length of the logs directly impact the amount of wood you get.
How much are you actually getting? The only way to really know is to measure the stack of wood and the lengths of the logs.
As a general rule, most wood suppliers cut wood 16 inches long. With that being said, a typical rick or face cord of firewood is 1/3 of a cord.
Since most homeowners who burn wood heat their house with a fireplace or wood stove, most stoves accommodate wood up to 16 inches. Wood that is cut to 24 inches is pretty long and could cause problems with some of the smaller stoves which is why it's not as common.
