What Is a Cord of Wood?
A cord of wood calculator helps you determine how much firewood you have by calculating the total number of full cords or face cords in your woodpile. Simply enter your stack’s dimensions, and the calculator will estimate the volume. If you also enter the price per cord, it can calculate the total value of your firewood.
This guide explains what a cord of wood is, how to calculate it, and how to measure both full cords and face cords accurately.
How to Calculate a Cord of Wood
A cord of wood is the standard unit used in the United States and Canada to measure stacked firewood or pulpwood. A full cord consists of neatly stacked logs with minimal air gaps.
Standard Cord Dimensions
- Length: 8 ft (2.44 m)
- Width (Depth): 4 ft (1.22 m)
- Height: 4 ft (1.22 m)
This equals a total volume of:
- 128 cubic feet (ft³)
- 3.62 cubic meters (m³)
The term “cord” is believed to have originated from the cord or rope traditionally used to measure stacked firewood.
How to Calculate a Cord of Wood
To calculate the number of full cords, use the following formula:
In Feet
Number of Cords = (Length × Width × Height) ÷ 128
In Meters
Number of Cords = (Length × Width × Height) ÷ 3.6246
Example
Suppose your firewood stack measures:
- Length: 15 ft
- Width: 6 ft
- Height: 7 ft
Calculation:
(15 × 6 × 7) ÷ 128 = 4.92 cords
Your woodpile contains approximately 4.9 cords of firewood.
What Is a Face Cord of Wood?
A face cord is a smaller unit of firewood measurement. It has the same height and length as a full cord but is only one log deep.
For standard 16-inch logs, the dimensions are:
- Length: 8 ft
- Depth: 16 in (1⅓ ft or 40.6 cm)
- Height: 4 ft
A face cord contains approximately one-third of a full cord.
Face Cord Formula
For standard 16-inch logs:
In Feet
Face Cords = (Length × 1⅓ × Height) ÷ 42.67
In Meters
Face Cords = (Length × 0.406 × Height) ÷ 1.208
Example
If your stack measures:
- Length: 7 ft
- Height: 4 ft
Calculation:
(7 × 1⅓ × 4) ÷ 42.67 = 0.875 face cords
Your stack contains approximately 0.88 face cords.
How to Use the Cord of Wood Calculator
Using the calculator is simple:
- Enter the length, width, and height of your firewood stack.
- Change the measurement units if necessary.
- If you already know the total volume, enter it directly.
- The calculator will automatically display:
- Total full cords
- Percentage of one full cord
- To calculate face cords, enter a width of 16 inches.
- Enter the price per cord to estimate the total value of your firewood.
How Much Does a Cord of Wood Weigh?
Using the calculator is simple:
- Enter the length, width, and height of your firewood stack.
- Change the measurement units if necessary.
- If you already know the total volume, enter it directly.
- The calculator will automatically display:
- Total full cords
- Percentage of one full cord
- To calculate face cords, enter a width of 16 inches.
- Enter the price per cord to estimate the total value of your firewood.
How Much Is a Quarter Cord of Wood?
A ¼ cord has a total volume of 32 cubic feet.
Typical dimensions include:
- Height: 4 ft
- Length: 6 ft
- Depth: 16 in
Using the cord formula:
(6 × 4 × 1.333) ÷ 128 = 0.25 cords
Therefore, the stack equals one-quarter of a full cord.

Frequently Asked Questions
How many face cords equal one full cord?
A standard face cord is approximately one-third of a full cord, assuming the logs are 16 inches long.
Can I calculate cords using metric units?
Yes. Measure the stack in meters and divide the total volume by 3.6246 m³ to determine the number of full cords.
Why does cord weight vary?
Wood weight depends on the species and moisture content. Fresh-cut wood weighs significantly more than seasoned or kiln-dried firewood.
Can this calculator estimate firewood value?
Yes. Simply enter the price per cord, and the calculator will estimate the total value of your woodpile based on the calculated number of cords.
