How to Calculate Firewood Volume
Firewood is typically measured in cords, where: 1 cord = 128 cubic feet of stacked wood, including the air gaps between pieces.
To calculate the volume:
- Measure the length, width, and height of your firewood stack.
- Convert the dimensions to feet if they’re in another unit.
- Formula to calculate firewood stack volume in cord:
Our calculator handles all the unit conversions and real time result for you.
Example Calculation:
If you have a stack that’s 4 feet long, 4 feet wide, and 8 feet high:
\text{Volume in cords} = \frac{4 \times 4 \times 8}{128} = 1 \, \text{cord}This means your stack equals 1 full cord of firewood.
How much wood is 1 cord of firewood?
A cord of firewood is a stack measuring 4 feet high, 4 feet deep, and 8 feet long, which equals 128 cubic feet. The actual wood content (excluding air gaps) is about 85-90 cubic feet, depending on the wood’s size and stacking method.
How much firewood do I need per day?
The amount of firewood needed daily depends on:
- Weather: Colder days require more wood.
- Wood type: Dense woods like oak burn longer than softwoods like pine.
- Usage: A wood stove or fireplace typically burns 1/4 to 1/2 cord per week during winter, translating to 3-6 cubic feet per day.
Plan on 1 to 1.5 cords per month for continuous winter heating.
