Calculate how many cords of firewood you need for the season based on stack dimensions, heating usage, and how long you plan to burn.
Frequently Asked Questions
How big is a cord of firewood?
A full cord is a stack measuring 4 feet high by 4 feet deep by 8 feet long, equaling 128 cubic feet of stacked wood.
How many cords does a house need for winter?
It varies widely based on climate, insulation, and whether wood is a primary or supplemental heat source, but 3-6 cords per season is common for regular wood-burning households.
What if my shortfall is negative?
A negative shortfall means your current stack already covers your season's needs, and you don't need to buy additional cords.
