Wood Cord Measurements Explained (Arborist’s Guide To Precision)

Okay, let’s dive into the world of wood cord measurements, precision, and all things firewood!

Wood Cord Measurements Explained (Arborist’s Guide to Precision)

Let’s face it: there’s something deeply satisfying about a well-stocked woodpile. For some, it’s about self-sufficiency, a way to thumb your nose at rising energy costs. For others, it’s the primal connection to nature, the smell of woodsmoke on a crisp winter evening. Maybe you’re an arborist, like I once was, supplementing your income during the off-season. Whatever the reason, understanding wood cord measurements is essential for getting the most bang for your buck – or, more accurately, the most heat for your stack!

I remember one particular winter in the Adirondacks. I was running a small tree service, and the snow was piled high. Firewood was in high demand, and the prices were soaring. I thought I had a great deal lined up, a “full cord” of seasoned maple for a steal. Turns out, the “cord” was more like a generous face cord, and the maple was anything but seasoned. Since then, I’ve dedicated myself to learning everything I can about wood, from species identification to precise measurement techniques. So, let’s get started and make sure you don’t end up with a similar story to tell!

Understanding the Basics: What is a Cord?

Let’s cut to the chase. A cord is a precisely defined unit of measurement for firewood. It’s not some vague, subjective estimate. It’s a legal standard, and knowing it can save you a lot of money and frustration.

The Legal Definition of a Cord

A cord is defined as a tightly stacked pile of wood measuring 4 feet high, 4 feet wide, and 8 feet long. This equates to 128 cubic feet. Now, before your eyes glaze over, let’s break that down. This measurement includes the wood, air space between the pieces, and bark.

It’s important to understand that a “cord” refers to the volume of wood, not the weight. The weight of a cord will vary significantly depending on the wood species and its moisture content. A cord of freshly cut oak will weigh considerably more than a cord of seasoned pine.

Why 128 Cubic Feet Matters

That 128 cubic feet is the benchmark. When you order a cord of wood, that’s what you should be getting. Anything less, and you’re being shortchanged. Think of it like buying gasoline – you expect a gallon to be a gallon, right? The same principle applies to firewood.

Beyond the Cord: Face Cords, Ricks, and Other Misnomers

This is where things get tricky. You’ll often hear terms like “face cord,” “rick,” or “pile” used to describe firewood quantities. These terms are not standardized and can vary widely from seller to seller.

Face Cord (or Rick): A face cord is typically defined as a pile of wood 4 feet high and 8 feet long, but the depth is variable. It’s essentially one-third of a cord if the wood is 16 inches long. However, some sellers might use 12-inch or 24-inch lengths, making the volume significantly different. Always clarify the length of the wood when dealing with face cords or ricks.
Pile: This is the most ambiguous term of all. A “pile” of wood could be anything from a few armfuls to a small mountain. It’s best to avoid buying wood described as a “pile” unless you can clearly measure the dimensions and calculate the approximate volume.

Measuring Wood Accurately: A Step-by-Step Guide

Okay, you know what a cord is. Now, how do you make sure you’re getting what you pay for? Here’s a practical guide to measuring firewood accurately.

Tools You’ll Need

Measuring Tape: A good quality measuring tape, preferably one that’s at least 25 feet long.
Calculator: For calculating the volume of the wood pile.
Notebook and Pen: To record your measurements.
Level (Optional): If the ground is uneven, a level can help you ensure accurate height measurements.

Step-by-Step Measurement Process

Assess the Pile: Before you start measuring, take a good look at the pile. Is it neatly stacked? Is the wood relatively uniform in length? Are there any obvious gaps or irregularities?
Measure the Height: Measure the height of the pile at several points along its length. Take an average of these measurements to account for any variations. Use the level, if needed, to ensure you’re measuring vertically.
Measure the Width: Measure the width of the pile at several points along its height. Again, take an average of these measurements.
Measure the Length: Measure the length of the pile. This is the easiest measurement to take, but make sure you’re measuring along the longest side of the pile.
Calculate the Volume: Multiply the height, width, and length to get the volume in cubic feet. For example, if the pile is 4 feet high, 4 feet wide, and 8 feet long, the volume is 4 x 4 x 8 = 128 cubic feet.
Account for Gaps: If the pile is loosely stacked or contains significant gaps, you may need to estimate the percentage of air space and subtract that from the total volume. This is a subjective process, but it’s better than ignoring the gaps altogether. I’ve found that estimating 10-15% for loosely stacked wood is usually a reasonable starting point.
Compare to a Cord: Divide the calculated volume by 128 to determine how many cords you have. For example, if the volume is 64 cubic feet, you have 64 / 128 = 0.5 cords (or half a cord).

Example Scenario: Measuring a Rick of Wood

Let’s say you’re buying a “rick” of wood that the seller claims is one-third of a cord. You measure the pile and find that it’s 4 feet high, 8 feet long, and 16 inches deep (which is 1.33 feet).

Volume Calculation: 4 feet (height) x 8 feet (length) x 1.33 feet (depth) = 42.56 cubic feet.
Cord Equivalent: 42.56 cubic feet / 128 cubic feet per cord = 0.33 cords.

In this case, the seller’s claim is accurate. However, always double-check the measurements yourself to be sure.

Wood Species and Their Impact on Measurement

Not all wood is created equal. The species of wood can significantly affect its density, weight, and heating value. This, in turn, can influence how you perceive the volume of a cord.

Density and Heating Value: A Quick Overview

Hardwoods: Hardwoods like oak, maple, beech, and ash are denser and have a higher heating value than softwoods. This means they burn longer and produce more heat per unit volume.
Softwoods: Softwoods like pine, fir, spruce, and cedar are less dense and have a lower heating value. They burn faster and produce less heat, but they are also easier to ignite.

How Species Affect Perceived Volume

A cord of oak will appear smaller than a cord of pine because the oak is denser. The pieces will be heavier and more tightly packed, resulting in less air space. This is why it’s important to consider the species of wood when evaluating a cord.

Common Firewood Species and Their Characteristics

Here’s a quick rundown of some common firewood species and their key characteristics:

Species	Density	Heating Value	Burning Characteristics
Oak	High	High	Burns slowly and steadily, produces excellent coals, can be difficult to split.
Maple	High	High	Burns well, produces good heat, splits easily.
Beech	High	High	Excellent firewood, burns long and hot, produces little smoke.
Ash	High	High	Burns well even when green, splits easily, produces little smoke.
Birch	Medium	Medium	Burns quickly, produces good heat, smells nice, can be messy.
Pine	Low	Low	Burns quickly, produces less heat, can be very resinous, creates more smoke and creosote.
Fir	Low	Low	Similar to pine, burns quickly, produces less heat.
Spruce	Low	Low	Similar to pine and fir, burns quickly, produces less heat.
Cedar	Low	Low	Burns quickly, produces less heat, aromatic, good for kindling.

Data Point: Studies have shown that oak can produce up to 50% more heat per cord than pine. This is a significant difference that should be considered when comparing prices.

The Importance of Seasoning

Seasoning refers to the process of drying wood to reduce its moisture content. Green wood (freshly cut wood) can contain up to 50% moisture, while seasoned wood typically has a moisture content of 20% or less.

Benefits of Seasoning:
- Burns more efficiently and produces more heat.
- Creates less smoke and creosote.
- Is easier to ignite.
- Weighs less, making it easier to handle.
How to Season Wood:
- Split the wood into smaller pieces.
- Stack the wood in a single row, off the ground, in a sunny and windy location.
- Allow the wood to dry for at least six months, preferably a year or more.

Insight: The best way to determine if wood is properly seasoned is to use a moisture meter. A good moisture meter will give you an accurate reading of the wood’s moisture content.
