Tired of guessing how much wood is in your pile? Use our professional firewood calculator to determine the exact number of cords in your stack based on its height, width, and length.
Firewood Calculator
Firewood Calculator Formula:
Source: University of Missouri Extension – Wood Fuel Properties
Variables:
- Length: The horizontal distance from one end of the stack to the other.
- Width (Depth): The length of the individual logs (usually 16 or 24 inches).
- Height: The average vertical measurement of the wood pile.
- Price: The market rate for one full cord (128 cubic feet).

What is Firewood Calculator?
A firewood calculator is an essential tool for homeowners and wood sellers to verify the volume of a wood delivery. Since firewood is traditionally sold by the “cord,” which is a measurement of volume rather than weight, it can be difficult to eye-ball.
By calculating the cubic footage (Length x Width x Height) and dividing it by the standard 128 cubic feet that make up a full cord, this calculator provides an objective measurement of your fuel supply. This ensures you get exactly what you paid for.
How to Calculate Firewood Calculator (Example):
- Measure your stack. Suppose it is 16 feet long, 4 feet deep, and 4 feet high.
- Multiply the dimensions: 16 × 4 × 4 = 256 cubic feet.
- Divide by 128: 256 / 128 = 2.0 Cords.
- If the price is $250 per cord, your total value is 2.0 × $250 = $500.
Frequently Asked Questions (FAQ):
What is a full cord of wood? A full cord is a stack of wood measuring 4 feet high by 4 feet deep by 8 feet long, totaling 128 cubic feet.
What is a face cord? A face cord is usually a stack 4 feet high by 8 feet long, but only one log deep (typically 16 inches). It is roughly 1/3 of a full cord.
Does the wood type affect the cord measurement? No. A cord is a measure of volume. However, different wood types (like Oak vs. Pine) will have different weights and heating values (BTUs) per cord.
How should I stack wood for accurate measurement? Wood should be stacked neatly and tightly (“ranked and well-stowed”) to ensure minimal air gaps between logs for an accurate volume reading.
