How Much Wood Fits in a Truck Bed? (Cord Measurement Explained)

Let’s get started!

The Hidden Benefits of Understanding Firewood Volume: More Than Just a Full Truck Bed

We often think about firewood in terms of warmth and cozy nights by the fire. It’s about more than just avoiding getting shortchanged. It’s about efficiency, planning, and maximizing your investment in home heating, or even your small firewood business.

Think of it this way: accurately measuring wood is like understanding the recipe for a perfect cake. You wouldn’t just throw ingredients in willy-nilly, would you? You’d want to know the precise measurements to ensure a delicious outcome. The same principle applies to firewood. Knowing your volumes allows you to properly season wood, predict your heating needs, and even negotiate better prices.

I remember one year, I thought I’d gotten a great deal on a “truckload” of firewood. Turns out, the guy had stacked it loosely, leaving huge gaps. I ended up with significantly less than I anticipated and scrambling to find more wood mid-winter. This guide is designed to empower you with that knowledge.

The State of the Firewood Industry: A Global Perspective

Before we dive into the nitty-gritty of cord measurements and truck bed capacities, let’s take a quick look at the current state of the firewood industry. Globally, the demand for firewood remains significant, especially in regions where it’s a primary heating source.

• Global Demand: According to a recent report by the Food and Agriculture Organization (FAO) of the United Nations, fuelwood still accounts for a substantial portion of energy consumption in many developing countries. Even in developed nations, there’s a resurgence of interest in wood heating, driven by rising energy costs and environmental concerns.
• Market Growth: The firewood market is experiencing steady growth, with a projected annual growth rate of around 3-5% over the next five years. This growth is fueled by both residential and commercial demand.
• Sustainability Concerns: Sustainable forestry practices are becoming increasingly important. Consumers are demanding responsibly sourced firewood, and regulations are tightening to prevent deforestation.
• Technology Adoption: Modern wood processing techniques, including the use of efficient wood splitters and firewood processors, are becoming more prevalent, particularly among commercial firewood producers.

For small workshops and independent loggers, this means opportunities exist, but also challenges. Staying competitive requires understanding market trends, adopting efficient practices, and ensuring sustainable sourcing.

Understanding Key Concepts: From Green Wood to Cords

Let’s start with the basics. If you’re new to the world of firewood, some of the terminology can be confusing.

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood that has a high moisture content. Seasoned wood, on the other hand, has been dried for a period of time, reducing its moisture content. Seasoned wood burns hotter, cleaner, and is much easier to ignite. The ideal moisture content for firewood is typically between 15% and 20%. Burning green wood is like trying to light a soggy newspaper – it’s smoky, inefficient, and can lead to creosote buildup in your chimney.
• Cord: A cord is a precisely defined unit of measurement for firewood. It’s equal to a stack of wood that measures 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. Note that this is not the same as 128 stacked cubic feet. There will be air gaps in the stack.
• Face Cord (or Rick): A face cord, also known as a rick or stove cord, is a stack of wood that is 4 feet high and 8 feet long, but its width varies depending on the length of the individual pieces of wood. A face cord is not a legally defined unit of measurement, so the amount of wood in a face cord can vary significantly. This is where things get tricky!
• BTU (British Thermal Unit): BTU is a measure of the heat content of fuel. Different types of wood have different BTU ratings. For example, hardwoods like oak and maple have higher BTU ratings than softwoods like pine and fir.
• Air Drying: The process of reducing the moisture content of firewood by stacking it in a way that allows air to circulate. Proper air drying is crucial for efficient burning and reducing creosote buildup.

Determining Truck Bed Capacity: The Math Behind the Wood

This is where the rubber meets the road – or rather, where the wood meets the truck bed. Determining how much wood fits in your truck bed requires a bit of math, but it’s essential for getting a fair deal and planning your firewood needs.

1. Measure Your Truck Bed: Start by measuring the interior dimensions of your truck bed: length, width, and height (of the sides). Use a measuring tape and record these measurements in feet.

   • Example: Let’s say your truck bed is 8 feet long, 4 feet wide, and 2 feet high.

   • Calculate the Cubic Footage: Multiply the length, width, and height to find the cubic footage of your truck bed.

   • Example: 8 feet x 4 feet x 2 feet = 64 cubic feet.

   • Account for Stacking Efficiency: Because firewood is stacked with air gaps, you won’t be able to fit a full 64 cubic feet of solid wood into your truck bed. A good rule of thumb is to assume a stacking efficiency of around 60-70%. This means that only 60-70% of the space in your truck bed will actually be occupied by wood.

   • Example: Using a stacking efficiency of 65%, multiply the cubic footage of your truck bed by 0.65.

     • 64 cubic feet x 0.65 = 41.6 cubic feet of wood.

   • Calculate the Fraction of a Cord: Divide the cubic footage of wood that fits in your truck bed by 128 (the cubic footage of a cord).

   • Example: 41.6 cubic feet / 128 cubic feet per cord = 0.325 cords.

   This means that your truck bed can hold approximately 0.325 cords of firewood.

Important Considerations:

• Truck Bed Size Variations: Truck bed sizes vary significantly depending on the make and model of the truck. Short beds, long beds, and different cab configurations all affect the available space. Always measure your own truck bed to get accurate results.
• Wood Length: The length of the firewood pieces also affects how much you can fit in your truck bed. Shorter pieces tend to stack more tightly, allowing you to fit more wood.
• Stacking Method: How you stack the wood in your truck bed also matters. A tightly packed, organized stack will hold more wood than a loosely thrown pile.
• Weight Capacity: Be mindful of your truck’s weight capacity. Firewood can be surprisingly heavy, especially when it’s green. Overloading your truck can damage the suspension and make it unsafe to drive. Always check your truck’s owner’s manual for weight capacity information.

Tool Selection: Chainsaws vs. Axes, and Everything In Between

Once you know how much wood you need, you’ll need the right tools to prepare it. The choice between a chainsaw and an axe is a fundamental one, and it depends on your needs and preferences.

• Chainsaws: Chainsaws are powerful tools for felling trees, bucking logs (cutting them into shorter lengths), and even some splitting.

  • Pros: Fast, efficient, and can handle large logs with ease.
  • Cons: Requires maintenance, can be dangerous if not used properly, and can be noisy.
  • Recommendations: For occasional firewood cutting, a gas-powered chainsaw with a 16-18 inch bar is a good choice. For heavier use, consider a more powerful model with a longer bar. Battery-powered chainsaws are also becoming increasingly popular for their convenience and quiet operation.

  • Axes: Axes are traditional tools for splitting wood. They require more physical effort than chainsaws, but they are also quieter, simpler, and don’t require fuel or maintenance.

  • Pros: Simple, reliable, and can be a good workout.

  • Cons: Requires more physical effort, can be slow for large quantities of wood, and may not be suitable for very large logs.
  • Recommendations: A splitting axe with a heavy head and a long handle is ideal for splitting firewood. A maul is a heavier type of axe that is designed for splitting particularly tough or knotty wood.

  • Other Essential Tools:

  • Safety Gear: This is non-negotiable. Always wear safety glasses, hearing protection, gloves, and sturdy boots when working with wood. A chainsaw helmet with a face shield is also highly recommended.

  • Measuring Tools: A measuring tape and a chainsaw felling wedge are essential for accurate cutting and safe tree felling.
  • Log Splitter: If you’re processing large quantities of firewood, a log splitter can save you a tremendous amount of time and effort. Hydraulic log splitters are the most common type, but manual log splitters are also available for smaller jobs.
  • Cant Hook/Peavey: These tools are used to roll and position logs, making it easier to cut and split them.
  • Wedges and Sledgehammer: Useful for splitting tough logs that are difficult to split with an axe alone.
  • Moisture Meter: This tool measures the moisture content of wood, allowing you to determine when your firewood is properly seasoned.

I’ve always found that investing in quality tools pays off in the long run. A well-maintained chainsaw or a sharp axe can make a huge difference in your efficiency and safety.

Safe Tree Felling: A Step-by-Step Guide

Felling trees is one of the most dangerous aspects of firewood preparation. It’s crucial to take safety precautions and follow proper techniques.

1. Assess the Tree: Before you start cutting, carefully assess the tree and its surroundings. Look for dead branches, power lines, and other hazards. Determine the tree’s lean and the direction it will naturally fall.
2. Plan Your Escape Route: Clear a path away from the tree at a 45-degree angle to the direction of the fall. This will give you a safe escape route if the tree falls unexpectedly.
3. Make the Notch Cut: The notch cut is a wedge-shaped cut that determines the direction of the fall. It should be made on the side of the tree that you want it to fall towards. The notch should be about one-third of the tree’s diameter.
4. Make the Back Cut: The back cut is made on the opposite side of the tree from the notch cut. It should be slightly higher than the bottom of the notch cut. Leave a hinge of wood between the back cut and the notch cut. This hinge will help control the direction of the fall.
5. Use a Felling Wedge (If Necessary): If the tree doesn’t start to fall on its own, you can use a felling wedge to help push it over. Insert the wedge into the back cut and drive it in with a sledgehammer.
6. Retreat and Observe: Once the tree starts to fall, retreat along your escape route and watch the tree fall. Make sure that no one is in the path of the falling tree.

Safety First!

• Never fell trees alone. Always have someone nearby who can help in case of an emergency.
• Wear appropriate safety gear, including a chainsaw helmet with a face shield.
• Be aware of your surroundings and the potential hazards.
• If you’re not comfortable felling a tree, hire a professional arborist.

De-limbing and Bucking: Turning Trees into Firewood

Once the tree is on the ground, the next step is to de-limb it (remove the branches) and buck it (cut it into shorter lengths).

1. De-limbing: Start by removing the larger branches with a chainsaw. Be careful not to cut into the trunk of the tree. Use a hand axe or pruning saw to remove smaller branches.

2. Bucking: Cut the trunk into lengths that are suitable for your fireplace or wood stove. The ideal length will depend on the size of your appliance. A common length is 16 inches. Use a measuring tape to ensure that the pieces are uniform in length.

   • Pro Tip: Use a sawbuck to support the log while you’re bucking it. This will make the job easier and safer.

Splitting Logs: From Rounds to Firewood

Splitting logs can be a challenging but rewarding task. It’s important to use the right technique and to take safety precautions.

1. Choose the Right Tool: Use a splitting axe or maul for splitting logs. A splitting axe has a thinner blade than a maul and is better for splitting smaller logs. A maul has a heavier head and is better for splitting larger, tougher logs.
2. Position the Log: Place the log on a solid surface, such as a chopping block. Make sure the log is stable and won’t roll or move while you’re splitting it.
3. Aim for the Crack: Look for cracks or seams in the log. These are the weakest points and will be the easiest to split.
4. Swing with Force: Swing the axe or maul with force, aiming for the crack in the log. Use your whole body to generate power.
5. Follow Through: Follow through with your swing, allowing the axe or maul to split the log completely.
6. Use Wedges (If Necessary): If the log is particularly tough or knotty, you may need to use wedges to split it. Drive the wedges into the crack with a sledgehammer.

Safety Tips:

• Wear safety glasses and gloves.
• Keep your feet out of the path of the axe or maul.
• Don’t try to split logs that are too large or too knotty.
• Take breaks when you’re tired.

Wood Species and Their Properties: Choosing the Right Wood for Your Needs

Not all firewood is created equal. Different types of wood have different properties, including BTU ratings, burning characteristics, and seasoning times.

• Hardwoods: Hardwoods are generally denser than softwoods and have higher BTU ratings. They burn longer and hotter, making them ideal for heating.

  • Oak: Oak is one of the best firewoods. It has a high BTU rating, burns slowly, and produces a long-lasting heat. It also seasons well.
  • Maple: Maple is another excellent firewood. It has a high BTU rating, burns cleanly, and produces a good amount of heat.
  • Ash: Ash is easy to split and seasons quickly. It has a good BTU rating and burns well.
  • Beech: Beech is a dense hardwood with a high BTU rating. It burns hot and produces a long-lasting heat. However, it can be difficult to split.

  • Softwoods: Softwoods are less dense than hardwoods and have lower BTU ratings. They burn quickly and produce less heat. They are often used for kindling or starting fires.

  • Pine: Pine is easy to ignite and burns quickly. It’s a good choice for kindling, but it’s not ideal for heating because it produces a lot of smoke and creosote.

  • Fir: Fir is similar to pine in its burning characteristics. It’s easy to ignite and burns quickly, but it’s not ideal for heating.
  • Spruce: Spruce is another softwood that is often used for kindling. It burns quickly and produces a lot of smoke.

Here’s a quick reference table:

Seasoning Firewood: The Key to Efficient Burning

Seasoning firewood is the process of drying it to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and is much easier to ignite.

1. Split the Wood: Splitting the wood exposes more surface area to the air, allowing it to dry more quickly.
2. Stack the Wood: Stack the wood in a single row, with the bark side up. This will help shed rain and prevent the wood from rotting.
3. Elevate the Wood: Elevate the wood off the ground using pallets or planks. This will allow air to circulate underneath the stack.
4. Provide Air Circulation: Stack the wood in a sunny, windy location. This will help the wood dry more quickly.
5. Cover the Top (Optional): Covering the top of the stack with a tarp can help protect the wood from rain and snow. However, be sure to leave the sides open to allow for air circulation.
6. Wait Patiently: Seasoning firewood takes time. Hardwoods typically take 6-12 months to season, while softwoods can be seasoned in 3-6 months.

How to Tell If Firewood Is Seasoned:

• Check the Moisture Content: Use a moisture meter to measure the moisture content of the wood. The ideal moisture content for firewood is between 15% and 20%.
• Look for Cracks: Seasoned firewood will often have cracks on the ends.
• Listen for a Hollow Sound: When you bang two pieces of seasoned firewood together, they will make a hollow sound.
• Feel the Weight: Seasoned firewood will be lighter than green wood.

Firewood Stacking Techniques: Maximizing Airflow and Space

How you stack your firewood can have a significant impact on how quickly it seasons and how much space it takes up.

• The Traditional Row Stack: This is the most common method. Stack the wood in a single row, with the bark side up. Elevate the wood off the ground and provide good air circulation.
• The Holzhaufen (Round Stack): This method involves stacking the wood in a circular pile. It’s a visually appealing method, but it can be less efficient for seasoning because the wood in the center of the pile doesn’t get as much air circulation.
• The Crib Stack: This method involves stacking the wood in a crisscross pattern. It’s a stable and space-efficient method, but it can be more time-consuming to build.
• The Pallet Stack: This is a simple and efficient method. Stack the wood on pallets to elevate it off the ground and provide good air circulation.

I personally prefer the traditional row stack because it’s easy to build and provides good air circulation.

Cost and Budgeting Considerations: Making Firewood Preparation Economical

Preparing your own firewood can save you money, but it’s important to factor in the costs of tools, fuel, and your time.

• Tool Costs: Chainsaws, axes, log splitters, and other tools can be expensive. Consider buying used tools or renting them to save money.
• Fuel Costs: Chainsaws and log splitters require fuel. Factor in the cost of gasoline or propane.
• Time Costs: Preparing firewood takes time. Consider the value of your time when deciding whether to prepare your own firewood or buy it from a supplier.
• Transportation Costs: If you’re harvesting wood from your own property, you’ll need to transport it to your home. Factor in the cost of fuel and vehicle maintenance.
• Maintenance Costs: Chainsaws and other tools require maintenance. Factor in the cost of repairs and replacement parts.

Tips for Saving Money:

• Buy firewood in bulk.
• Harvest wood from your own property (if you have permission).
• Split wood by hand (if you’re physically able).
• Season wood properly to maximize its burning efficiency.
• Maintain your tools to prolong their lifespan.

Troubleshooting: Common Pitfalls and How to Avoid Them

Even with the best planning, things can sometimes go wrong when preparing firewood. Here are some common pitfalls and how to avoid them:

• Dull Chainsaw: A dull chainsaw is dangerous and inefficient. Sharpen your chainsaw regularly.
• Stuck Axe: If your axe gets stuck in a log, don’t try to force it out. Use a wedge and sledgehammer to split the log apart.
• Back Pain: Splitting wood can be hard on your back. Use proper technique and take breaks when you’re tired.
• Wet Firewood: Wet firewood is difficult to ignite and produces a lot of smoke. Season your firewood properly before burning it.
• Creosote Buildup: Burning unseasoned wood can lead to creosote buildup in your chimney. Have your chimney inspected and cleaned regularly.
• Overloading Your Truck: Overloading your truck with firewood can damage the suspension and make it unsafe to drive. Be mindful of your truck’s weight capacity.

Case Studies: Successful Firewood Preparation Projects

Let’s look at a couple of real-world examples to illustrate the principles we’ve discussed.

• Case Study 1: The Suburban Firewood Enthusiast: John, a homeowner in suburban Minnesota, decided to supplement his natural gas heating with a wood-burning stove. He purchased a small, corded electric chainsaw, a splitting axe, and a moisture meter. He sourced oak firewood from a local supplier, paying close attention to the dimensions of a “face cord” to ensure he was getting a fair deal. He stacked the wood in his backyard, following the traditional row stack method. After a year of seasoning, he achieved a moisture content of 18%. He estimates that he saved approximately $500 on his heating bill that winter.
• Case Study 2: The Small-Scale Firewood Producer: Maria, a farmer in rural Vermont, saw an opportunity to supplement her income by selling firewood. She invested in a used hydraulic log splitter, a professional-grade chainsaw, and a firewood processor. She sustainably harvested ash and maple from her own property, carefully managing the forest to ensure long-term productivity. She established a reputation for selling high-quality, seasoned firewood, and built a loyal customer base. She now earns a significant portion of her income from her firewood business.

These case studies demonstrate that with the right knowledge, tools, and planning, anyone can successfully prepare firewood, whether for personal use or as a source of income.
