Frequently Asked Questions
How big is a cord of firewood?
A standard cord is a stack measuring 4 feet by 4 feet by 8 feet, equal to 128 cubic feet of stacked wood including air gaps.
Does this account for air gaps between logs?
Yes, the standard cord measurement (128 cubic ft) already assumes typical stacking with natural air gaps, so no extra adjustment is needed.
How much firewood do I need for a winter?
Typical usage for a primary wood-heated home in a cold climate is 3-5 cords per season, while occasional fireplace use may only need 0.5-1 cord.
