Decoding the Firewood Cord: A Beginner’s Guide

The term “cord” is thrown around a lot when buying and selling firewood, but what exactly is a cord? It’s more than just a pile of wood; it’s a standardized unit of measure. Understanding this standard is the first step to ensuring you get what you pay for (or charge fairly for what you sell).

What is a Cord of Firewood? The Legal Definition

A cord of firewood, by legal definition in the United States and Canada, is a precisely stacked pile of wood measuring 4 feet high, 4 feet wide, and 8 feet long. This equates to 128 cubic feet of total volume.

Important Considerations:

This 128 cubic feet includes the wood and the air spaces between the pieces.
The wood doesn’t have to be precisely 4 feet long. As long as the total volume is equivalent to a 4x4x8 foot stack, it’s considered a cord.
The official definition is crucial for legal transactions and consumer protection.

The Anatomy of a Cord: Wood vs. Air

While a cord contains 128 cubic feet of space, the actual amount of wood is considerably less. The air gaps between the logs account for a significant portion of the total volume. This “void space” varies depending on the size and shape of the wood, as well as how tightly it’s stacked.

Data Point: Studies have shown that a loosely stacked cord can contain as little as 60-70 cubic feet of solid wood, while a tightly stacked cord might contain 80-90 cubic feet. This difference can significantly impact the amount of heat you get from a cord of wood.

Common Firewood Measurements: Beyond the Full Cord

While the full cord is the gold standard, you’ll often encounter other terms like “face cord,” “rick,” or “stove cord.” These terms are not legally defined and can vary significantly from seller to seller.

Face Cord (or Rick): Typically refers to a stack of wood 4 feet high and 8 feet long, but with a width that varies. Often the length of the wood pieces themselves (e.g. 16 inches). This is where things get tricky! Since the width isn’t standardized, a face cord can be anywhere from 1/3 to 1/2 of a full cord. Always clarify the width before agreeing to a price.
Other Terms: Terms like “truckload” or “pile” are even less precise. Avoid these terms whenever possible and insist on a measurement based on cubic feet.

Personal Anecdote: The Case of the Misleading Face Cord

I remember one time when I was just starting out, I ordered a “face cord” of oak from a local seller. The price seemed great, but when the wood arrived, it was significantly smaller than I expected. When I questioned the seller, he explained that his “face cord” was only 12 inches wide – barely a third of a full cord! This experience taught me a valuable lesson: always ask for specific dimensions and calculate the cubic footage before buying.

Measuring Firewood Like a Pro: Step-by-Step Guide

Now that you understand the definition of a cord and its variations, let’s get into the practical aspects of measuring firewood.

Measuring a Full Cord: The Gold Standard

The most accurate way to ensure you’re getting a full cord is to measure it yourself. Here’s how:

Choose a Level Surface: Select a flat, even area to stack your wood. This will ensure accurate measurements.
Build the Frame: Create a rectangular frame that is 4 feet high, 4 feet wide, and 8 feet long. You can use stakes and string, or build a temporary wooden frame.
Stack Tightly: Stack the wood as tightly as possible within the frame. Minimize air gaps by alternating the direction of the logs and using smaller pieces to fill in spaces.
Level the Top: Once the frame is full, level the top of the stack.
Verify Dimensions: Double-check the height, width, and length to ensure they are accurate.

Pro Tip: Use a measuring tape with both feet and inches to ensure precise measurements.

Calculating Cubic Feet: The Math Behind the Measurement

If you can’t build a frame, you can still calculate the volume of a wood pile by measuring its dimensions and using a simple formula:

Volume (cubic feet) = Height (feet) x Width (feet) x Length (feet)

Example: A pile of wood that is 4 feet high, 6 feet wide, and 4 feet long has a volume of 4 x 6 x 4 = 96 cubic feet. This is less than a full cord (128 cubic feet).

Converting to Cords: To convert cubic feet to cords, divide the volume by 128:

Cords = Volume (cubic feet) / 128

Example: A pile of wood with a volume of 96 cubic feet is equal to 96 / 128 = 0.75 cords.

Measuring Irregular Stacks: Estimating with Accuracy

Sometimes, you’ll encounter firewood stacks that aren’t perfectly rectangular. In these cases, you’ll need to estimate the volume by taking multiple measurements and averaging them.

Divide and Conquer: Divide the irregular stack into smaller, more manageable sections.
Measure Each Section: Measure the height, width, and length of each section.
Calculate Individual Volumes: Calculate the volume of each section using the formula above.
Add the Volumes: Add the volumes of all the sections to get the total volume of the stack.
Convert to Cords: Divide the total volume by 128 to get the equivalent number of cords.

Pro Tip: When measuring irregular stacks, be conservative with your estimates. It’s better to underestimate slightly than to overestimate and end up short.

Estimating Loose Firewood: The “Eyeball” Method

Estimating the volume of loose firewood (e.g., in a truck bed or a pile on the ground) is the most challenging. This requires experience and a good eye for volume. Here are some tips:

Visualize a Cord: Imagine what a full cord would look like in the space.
Break It Down: Divide the loose pile into smaller, more manageable sections.
Estimate Each Section: Estimate the volume of each section in cubic feet.
Add the Estimates: Add the estimates of all the sections to get the total volume.
Convert to Cords: Divide the total volume by 128 to get the equivalent number of cords.

Expert Insight: “Estimating loose firewood is more of an art than a science,” says seasoned logger, John Peterson. “It takes years of experience to develop a good eye for volume. The key is to practice and compare your estimates with actual measurements.”

The Hidden Factors: Wood Species, Moisture, and Stacking

The volume of a cord is only one piece of the puzzle. The type of wood, its moisture content, and how tightly it’s stacked all significantly impact the amount of heat you’ll get.

Wood Species: BTU Content and Burn Time

Different wood species have different densities and BTU (British Thermal Unit) content. Hardwoods like oak, maple, and ash have a higher BTU content than softwoods like pine, fir, and spruce. This means they produce more heat per unit of volume and burn longer.

Data Point: According to the U.S. Department of Energy, a cord of seasoned oak can produce up to 24 million BTUs, while a cord of seasoned pine might only produce 15 million BTUs.

Practical Implication: When buying firewood, consider the species. You might pay more for hardwoods, but you’ll get more heat for your money.

Moisture Content: The Key to Efficient Burning

The moisture content of firewood is critical. Green wood (freshly cut) contains a high amount of moisture, which reduces its BTU content and makes it difficult to burn efficiently. Seasoned wood (dried) has a lower moisture content, which allows it to burn hotter and cleaner.

Data Point: Green wood can have a moisture content of 50% or higher, while seasoned wood should have a moisture content of 20% or less.

How to Season Firewood:

Split the Wood: Splitting the wood increases its surface area, allowing it to dry faster.
Stack Loosely: Stack the wood in a single row with air gaps between the pieces.
Elevate the Stack: Elevate the stack off the ground using pallets or scrap wood.
Cover the Top: Cover the top of the stack with a tarp to protect it from rain and snow.
Allow Time to Dry: Allow the wood to dry for at least 6-12 months, depending on the species and climate.

Pro Tip: Use a moisture meter to check the moisture content of your firewood before burning it.

Stacking Density: Maximizing Heat Value

The way you stack your firewood can also impact its heat value. Tightly stacked wood will contain more solid wood per cord than loosely stacked wood. This means you’ll get more heat from a tightly stacked cord.

Best Stacking Practices:

Stack in Rows: Stack the wood in neat, orderly rows.
Alternate Directions: Alternate the direction of the logs to minimize air gaps.
Use Smaller Pieces: Use smaller pieces to fill in spaces between larger logs.
Tamp Down: Tamp down the stack periodically to settle the wood and reduce air gaps.
