Frequently Asked Questions
What is a cord of firewood?
A standard full cord is a stack measuring 4 feet by 4 feet by 8 feet, equal to 128 cubic feet of stacked wood, including air gaps between logs.
Why isn't stacking 100% efficient?
Round or irregular logs never pack perfectly. Typical stacks achieve 70-85% of the theoretical solid volume due to gaps between pieces, which this calculator accounts for.
How much firewood do I need for a winter?
This varies by climate and heating use, but many households burning wood as a primary heat source use 3 to 6 cords per season.
