what does a cord of wood weigh

3 min read 11-01-2025

Determining the weight of a cord of wood isn't a simple "one size fits all" answer. The weight fluctuates wildly depending on several key factors. This article will explore these factors and give you a better understanding of what to expect. Knowing the weight can be crucial for transportation, storage, and even pricing.

Factors Affecting the Weight of a Cord of Wood

The weight of a cord of wood varies dramatically depending on several factors:

1. Species of Wood

Different tree species have different densities. Dense hardwoods like oak and hickory will weigh considerably more than softer woods like pine or cedar. A cord of oak will be significantly heavier than a cord of pine, for example.

2. Moisture Content (Green vs. Seasoned)

This is perhaps the biggest factor affecting weight. "Green" wood, freshly cut and still containing significant moisture, will be much heavier than "seasoned" wood that has been dried for several months or even years. Seasoned wood can lose up to 20% or more of its initial weight through drying. This is why seasoned wood is often preferred for burning, as it burns hotter and cleaner.

3. Type of Wood (Split vs. Round)

Split wood generally weighs less than round wood of the same species and moisture content because splitting exposes more surface area for drying. This process reduces the overall moisture content, leading to weight loss.

4. Density of the Wood

Even within a species, wood density can vary depending on the tree's age, growth conditions, and the specific part of the tree. For example, the heartwood (the central part of the tree) tends to be denser than the sapwood (the outer layers).

Average Weight Estimates for a Cord of Wood

While precise weight is hard to pinpoint, here are some general estimates:

Green Hardwood: A cord of green hardwood can weigh between 4,000 and 6,000 pounds (2,000 – 3,000 kg).
Seasoned Hardwood: A seasoned cord of hardwood might weigh between 3,000 and 4,500 pounds (1,500 – 2,250 kg).
Green Softwood: A cord of green softwood typically weighs between 2,500 and 3,500 pounds (1,250 – 1,750 kg).
Seasoned Softwood: A seasoned cord of softwood may weigh between 1,800 and 2,500 pounds (900 – 1,250 kg).

Important Note: These are just rough estimations. The actual weight of your cord of wood could vary significantly based on the factors mentioned above.

How to Estimate the Weight of Your Specific Cord

If you need a more precise estimate, you could contact your wood supplier for species and moisture information. You could also weigh a smaller sample (e.g., a cubic foot) of wood and extrapolate to estimate the weight of a full cord.

Frequently Asked Questions

How much does a cord of firewood weigh in tons?

A cord of firewood can weigh between 2 and 3 tons depending on the factors mentioned above. Seasoned softwood will likely be on the lower end of this range, while green hardwood will be on the higher end.

What is the best way to measure a cord of wood?

A standard cord is a stack of wood measuring 4 feet high, 4 feet wide, and 8 feet long. Make sure there are no large gaps in the stack, and the wood is tightly stacked to get an accurate measurement.

How much does a half-cord of wood weigh?

A half-cord of wood will weigh approximately half the weight of a full cord. However, the same variables affecting a full cord will impact the weight of a half cord as well.

Conclusion

The weight of a cord of wood is highly variable. Understanding the key factors – species, moisture content, and whether it's split or round – will help you better estimate the weight. This knowledge is essential for planning transport, storage, and budgeting for your firewood needs. Remember, always communicate with your wood supplier for specifics about the wood you're buying.
