Free Cord of Wood Calculator

If you need to determine how much firewood you have stacked or calculate its monetary worth, a firewood calculator—often referred to as a cord of wood calculator—is the perfect solution. This online tool helps you measure the volume of a woodpile using the standard North American unit known as the cord, as well as the smaller face cord. By entering your local price per cord, the calculator also provides an estimated value of your firewood stack, letting you quickly assess how much that pile of logs is worth in your local market.

Understanding a Cord of Wood

A cord of wood is a predefined volume unit used for firewood and pulpwood. According to standard cord of firewood dimensions, a full stack measures 8 feet (2.44 m) in length, 4 feet (1.22 m) in height, and 4 feet (1.22 m) in depth. These three dimensions yield a total volume of 128 cubic feet (approximately 3.62 m³). The term “cord” likely comes from the cord or string once employed to tie around such a stack to verify its size. Knowing how much is a cord of wood is essential for anyone buying, selling, or simply managing firewood, as it provides a consistent baseline for comparison.

Formula for Calculating Cords

To convert the dimensions of a stacked pile into full cords, the wood volume calculator uses a straightforward formula. When all measurements are in feet:

$$\text{Cords} = \frac{\text{Length (ft)} \times \text{Width (ft)} \times \text{Height (ft)}}{128\ \text{ft}^3}$$

If you use metric units, the formula becomes:

$$\text{Cords} = \frac{\text{Length (m)} \times \text{Width (m)} \times \text{Height (m)}}{3.6246\ \text{m}^3}$$

For example, imagine a woodpile that is 12 feet long, 5 feet wide, and 4 feet tall. Plugging into the formula: $12 \times 5 \times 4 = 240$ cubic feet, divided by 128 gives 1.875 cords. This method works for any uniform stack of firewood and is the basis of every cord calculator.

The Face Cord Explained

A face cord is a smaller, more practical unit often used when firewood is cut to standard 16‑inch (about 0.41 m) lengths. In a face cord, the logs are stacked in a single row, so the stack’s depth is only 16 inches. The length (8 ft) and height (4 ft) remain the same as a full cord. Consequently, a face cord holds roughly one‑third the volume of a full cord—about 42.67 ft³ (1.208 m³). That’s why you’ll often hear experienced firewood sellers refer to a face cord calculator when dealing with standard‑length splits.

The formula for face cords, using dimensions in feet, is:

$$\text{Face cords} = \frac{\text{Length (ft)} \times 1.\overline{3}\ \text{ft} \times \text{Height (ft)}}{42.67\ \text{ft}^3}$$

Where $1.\overline{3}$ represents $\frac{16}{12}$ feet. In metric terms:

$$\text{Face cords} = \frac{\text{Length (m)} \times 0.406\ \text{m} \times \text{Height (m)}}{1.208\ \text{m}^3}$$

As a quick illustration: a stack 7 ft long and 4 ft high gives $(7 \times 1.\overline{3} \times 4) \div 42.67 \approx 0.875$ face cords—a handy figure when pricing a small stack.

Using the Wood Volume Calculator

The firewood calculator is designed to be intuitive. Follow these steps:

1. Enter the stack’s dimensions—length, width, and height—into the corresponding fields. You can click any unit label to switch between feet, meters, inches, centimeters, etc., making the tool flexible.
2. Alternative input: If you already know the total volume (e.g., from a previous calculation), enter it directly into the volume field.
3. View full cords: The calculator displays the number of full cords and the same value expressed as a percentage of one full cord, so you can instantly visualize the pile’s size.
4. Face cord measurement: For a face cord, set the width unit to inches and enter 16. The tool then shows the number of face cords and the corresponding percentage.
5. Value estimation: Enter the price per cord for your area. The calculator will multiply the number of cords (or face cords) by this price, giving you the total worth of the wood stack.

This step‑by‑step process removes guesswork and ensures you get accurate results whether you’re a homeowner buying a load of firewood or a supplier verifying inventory.

Why This Tool Matters

Knowing the exact volume of a firewood stack eliminates costly errors. With the cord of wood calculator, you no longer need to rely on rough visual estimates. It supports both US customary and metric units, handles full cords and face cords, and even accounts for local pricing. Whether you’re asking “how much is a cord of wood in my area?” or need to check whether a seller’s “face cord” matches the standard definition, this tool provides clear, instant answers.
