Cord of Wood Calculator
Measure a stacked wood pile and estimate how many full cords or face cords it contains.
Use it when buying firewood, splitting a delivery, or checking whether a stack is really the size it claims to be.

Run the calculation to see the wood volume.
Quick Answer
A full cord is 128 cubic feet, so divide the stack volume by 128 to get the number of cords.
How to Use It
- Choose feet or meters.
- Enter the stack length, height, and depth.
- Add the price per full cord if you want a cost estimate.
- Click Calculate to see the cord count and price.
Formula
Full cords = stack volume / 128 cubic feet
Face cords = stack volume / (8 x 4 x log length)
Worked Examples
Example 1: An 8 x 4 x 4 foot stack is exactly 1 full cord.
Example 2: An 8 x 4 x 1.333 foot stack is about 0.33 full cords, or 1 face cord with 16-inch logs.
Example 3: A 2.4 x 1.2 x 0.4 meter stack converts to the same cord logic after unit conversion.
How to Interpret Your Results
| Output | Meaning | Action |
|---|---|---|
| Full cords | The stack volume expressed as standard cords. | Use it for buying or selling firewood. |
| Face cords | The equivalent stack count for the chosen log depth. | Compare it carefully because face cords are not standardized everywhere. |
| Estimated cost | The price based on the number of full cords. | Multiply by the quoted price before you pay. |
Frequently Asked Questions
A face cord depends on log length, so its size changes if the wood is cut shorter or longer than usual.
Exact measurements are best, but the calculator still gives a good estimate if your stack is roughly rectangular and stacked tightly.
You can estimate it by using the pile's approximate bounding box, but the result will be less precise than a rectangular stack.
