What Is a Cord of Wood and How to Properly Measure It for Efficient Firewood Management?
What Is a Cord of Wood?
A cord of wood is a unit of measurement used to quantify firewood and pulpwood in the United States and Canada.
It refers to a well-stacked woodpile that occupies a volume of 128 cubic feet (3.62 m3).
The cord is legally defined by Measurement Canada in Canada and by statute in most states in the US.
It is equivalent to a stack of wood that measures 4 × 4 × 8 feet, or 128 cubic feet.
The amount of wood contained in a cord can vary depending on factors such as wood type, size, and straightness of the pieces, and amount of bark present.

Did You Know?
1. A cord of wood, often used for measuring firewood, originated from the French word “corde,” meaning “string.” This measurement dates back to the 17th century when firewood was bundled tightly with ropes.
2. The dimension of a standard cord of wood is 4 feet high, 4 feet wide, and 8 feet long, which is equivalent to 128 cubic feet or approximately 3.62 cubic meters.
3. In many parts of the United States, a cord of wood is legally defined as 128 cubic feet, while in some areas, it may vary slightly. However, in Canada, a cord is typically defined as 128 cubic feet, including the air space within the stack.
4. The type of wood used in a cord can significantly impact its energy content. For instance, a cord of oak wood can deliver more heat, as it is denser and has a higher energy content compared to softer woods like pine.
5. While most cords contain split firewood, some regions have specific terms for unsplit wood, such as a “rick” or “face cord.” A rick generally refers to a stack of wood that is 4 feet high and 8 feet long but varies in width, while a face cord typically measures 4 feet high and 8 feet long but has a depth of one log length.
Defining A Cord Of Wood
A cord of wood is a common unit of measure used to quantify firewood and pulpwood in the United States and Canada. It refers to a well-stacked woodpile that occupies a volume of 128 cubic feet (3.62 m3). The cord is legally defined by statute in most states in the US and by Measurement Canada in Canada.
The name “cord” originated from the practice of tying the wood into a bundle using a cord or string. This traditional method of bundling wood has been passed down through generations, and the term “cord” has become synonymous with stacked firewood.
To visualize a cord of wood, imagine a neatly stacked pile of wood that measures 4 feet wide, 4 feet deep, and 8 feet high. This stack amounts to 128 cubic feet, which is the standard measurement for a cord.
It’s important to note that the amount of wood contained in a cord can vary depending on several factors. Wood type, size and straightness of the pieces, and the amount of bark present all contribute to the overall volume of wood in a cord.
Measurement Standards For Cords Of Wood
The cord serves as a standardized unit of measure in order to ensure consistency and fair trade practices. In the United States, specific laws are in place in most states to define a cord and protect consumers from deceptive practices. Similarly, Measurement Canada establishes the legal standard for cords in Canada.
A cord is divided into cord feet, which have a length of 4 feet, a width of 4 feet, and a height of 1 foot. This measurement facilitates easy calculations and allows individuals to determine the volume of wood they are purchasing or using.
A standard cord typically consists of 4-foot long sticks that are stacked in a 4 × 8-foot rick. This type of cord is commonly sold for firewood and is suitable for residential heating needs.
Variations of a cord include the short cord and the long cord. A short cord is a 4 × 8-foot rick composed of shorter pieces, while a long cord is made up of longer pieces. These variations can be useful for specific firewood needs, such as wood-burning stoves or commercial applications.
- The cord serves as a standardized unit of measure.
- Specific laws define a cord in most US states.
- Measurement Canada sets the legal standard for cords in Canada.
- Cord feet measure 4 feet in length, 4 feet in width, and 1 foot in height.
- A standard cord is made up of 4-foot long sticks stacked in a 4 × 8-foot rick.
- Short cords and long cords are variations of a cord.
Alternative Measurements For Firewood Volume
While the cord is the standard measurement for firewood volume in the United States and Canada, there are alternative terms and measurements that exist in different regions or for specific purposes.
One such term is a face cord, which refers to a 4 × 8-foot stack of 1-foot-long pieces. This measurement is often used when purchasing firewood by the face cord, as it provides an indication of the amount of wood at a glance. However, it’s important to note that a face cord does not have the same volume as a full cord.
Additionally, the metric system uses measurements such as steres and cubic meters to quantify wood volume. One stere is approximately 0.276 cords. These measurements are widely used outside of the United States and Canada and provide consistency for international trade and conversions.
The Cord In Different Countries And Cultures
While the cord is predominantly used in the United States and Canada, variations of this unit of measure can be found in different countries and cultures.
In French-speaking countries, the corde was a unit of volume used before metrication. This historical measurement played a similar role to the cord, quantifying wood for heating and other purposes.
In Australia, an imperial cord was used to measure wood and firewood. It consisted of a stack that measured 4 feet wide, 4 feet deep, and 8 feet high, containing 128 cubic feet of wood. This measurement system provided a consistent and standard unit of measure for Australians.
Factors Affecting The Amount Of Wood In A Cord
The amount of wood contained in a cord can vary due to several factors. These factors include wood type, size and straightness of the pieces, and the amount of bark present.
Wood type plays a significant role in the density of the wood and, consequently, the volume it occupies in a cord. Hardwoods, such as oak or maple, generally have a higher density than softwoods like pine or fir. As a result, an equivalent volume of hardwood will typically contain more energy and burn longer than the same volume of softwood.
The size and straightness of the wood pieces also affect the amount of wood in a cord. Larger and straighter pieces of wood can be stacked more efficiently, reducing any gaps and increasing the overall volume of wood in a cord.
Similarly, the presence of bark can impact the amount of wood in a cord. Bark takes up space and can reduce the overall volume of usable wood in a cord. If the wood supplier includes bark in the measurement, it may result in less actual firewood being provided.
It is essential to consider these factors when purchasing or measuring a cord of wood to ensure you are receiving the appropriate amount for your needs.

Frequently Asked Questions
Why is it called a cord of wood?
The term “cord of wood” originates from its method of bundling. Originally, a cord was created by tying firewood together using a line or string, hence the name. This method ensured that the wood was securely stacked into a neat and organized bundle, making it easier to transport and measure. Over time, the term “cord of wood” became the standard unit for measuring firewood, despite more precise and standardized methods being available today.
Is a cord of wood a ton?
No, a cord of wood is not equivalent to a ton. A cord of Pine weighs 2.15 tons, while a cord of Hemlock weighs 2.4 tons.
How much wood is 1 cord?
One cord of wood is equivalent to a volume of 128 cubic feet. To visualize this, imagine a pile of wood measuring 8 feet long, 4 feet high, and 4 feet wide. This amount of wood can weigh up to 5,000 pounds. In comparison, a small pickup truck bed can hold approximately 1/2 (one-half) cord of wood, regardless of whether it has racks or not.
What is 2 cords of wood?
Two cords of wood is a significant amount that measures up to 256 cubic feet. Imagine neatly stacking individual pieces of firewood in parallel rows, ensuring compactness and minimizing gaps. It would result in a bulk of wood that provides a substantial supply for heating or fuel purposes. With two cords of wood, you can expect an ample amount of firewood to last through the cold winter days, keeping you warm and cozy.
