Quick summary
Step-by-step derivation
Use this Cord of Wood Calculator to estimate stacked firewood volume, full cords, reference face cords, and optional cost from the length, height, and depth of a wood stack.
Cord of Wood Calculation Method
Stack volume = length × height × depth
A standard full cord contains:
1 cord = 128 cubic feet
Therefore:
Full cords = stack volume ÷ 128
The calculator also uses a reference face cord based on a stack measuring 8 ft × 4 ft × 16 in deep:
Reference face cord ≈ 42.67 ft³
If a price per full cord is entered:
Estimated cost = full cords × price per cord
Example
Suppose a stacked pile measures 8 ft long, 4 ft high, and 4 ft deep.
Volume = 8 × 4 × 4 = 128 ft³
Full cords = 128 ÷ 128 = 1 cord
The stack therefore contains approximately 1 full cord of firewood.
Important Notes
- Measure firewood after it has been stacked compactly with pieces generally parallel and with minimal gaps.
- Stacked firewood volume includes air spaces between pieces; it is not solid wood volume.
- A face cord is not a fixed volume unless the log depth is specified.
- Terms such as face cord, rick, rack, pile, or truckload may have different meanings depending on the seller or location.
- Wood species, moisture content, seasoning, and log size affect heating value but do not change the cord-volume calculation.
- For purchases, follow your local weights-and-measures rules and verify the seller’s stated quantity.
