Firewood / Cord Calculator
How much firewood do you need for winter? This calculator estimates the number of cords required based on your home size, how much you rely on wood heat, and the length of your heating season. It also calculates the total cost at your local cord price.
A cord of firewood is a standard unit measuring 4 feet x 4 feet x 8 feet = 128 cubic feet. A face cord (or rick) is 4 x 8 feet but only one log-length deep (about 16 inches), making it roughly 1/3 of a full cord.
Typical season requirements:
- Occasional use: 1-2 cords per season
- Supplemental heat: 2-4 cords per season
- Primary heat source: 4-8 cords per season
Best firewood by heat output: oak, hickory, maple, ash, birch. Softwoods like pine burn fast and produce more creosote.
