A standard cord has a volume of 128 cubic feet. This figure also includes the air space between and around the wood. The actual volume in a standard cord is between 60 and 100 cubic feet; depending on how tightly the wood is packed. Assuming that you are comparing two standard cords of different species but the same volume and moisture content, the denser species will provide more BTU’s. The table of wood species/ densities reveals more helpful guidelines.
