Firewood Calculator

A well-insulated 2,000 sqft home using wood as primary heat needs 3-5 cords for a 5-month winter. Supplemental heating needs 1-2 cords.

A cord is a stack 4×4×8 feet, totaling 128 cubic feet. A face cord is 4×8 but only 16 inches deep — about 1/3 of a full cord.

Dense hardwoods burn longest: oak (24+ million BTU/cord), hickory (28 million), and maple (24 million). Softwoods like pine burn fast but produce more creosote.
