How Much Wood Fits in a 6 Foot Bed (5 Pro Tips for Max Load)
How Much Wood Fits in a 6 Foot Bed (5 Pro Tips for Max Load)
Investing in firewood is more than just buying fuel; it’s investing in comfort, security, and sometimes, a little bit of self-sufficiency. But before you hitch up the trailer or back your pickup truck, let’s talk about maximizing your return on that investment. Specifically, how much wood really fits in a 6-foot truck bed, and how to make sure you’re getting the most bang for your buck (or cord, as it were).
I’ve been around wood my entire life, from helping my grandpa stack firewood as a kid to managing my own small woodlot. I’ve learned a thing or two about volume, weight, and the sneaky ways a seemingly full truck bed can be surprisingly light on actual firewood. This article isn’t just about calculations; it’s about sharing hard-earned knowledge and practical tips to help you become a savvy firewood buyer or harvester.
Understanding the Basics: Cords, Truck Beds, and Loose Loads
First, let’s establish a common language. Firewood is typically sold by the cord, which is a neatly stacked pile measuring 4 feet high, 4 feet wide, and 8 feet long, totaling 128 cubic feet. A “rick” or “face cord” is a common term, but it’s crucial to understand that it’s not a standard measurement. It’s simply a stack 4 feet high and 8 feet long, but the width (the length of the firewood pieces) can vary, making it a less reliable measure.
A 6-foot truck bed, on the other hand, is just that: a rectangular space 6 feet long, typically 4 feet wide (or slightly wider), and with varying depths depending on the truck model. The challenge comes in when you’re dealing with loose loads, which are never as compact as a neatly stacked cord.
The first pro tip is to get your measurements right. I can’t tell you how many times I’ve seen folks underestimate the volume of their truck bed. Here’s how to calculate the cubic feet of your truck bed:
- Measure the inside length, width, and depth of your truck bed in feet. If you measure in inches, divide by 12 to convert to feet.
- Multiply the length x width x depth. This gives you the cubic footage.
For example, let’s say your 6-foot bed is actually 6.5 feet long (many are), 4 feet wide, and 2 feet deep. The calculation would be: 6.5 ft x 4 ft x 2 ft = 52 cubic feet.
Now, the tricky part: a loose load of firewood will never fill that entire 52 cubic feet with solid wood. There will be air gaps. This is where the “factor of looseness” comes into play.
Pro Tip #1: The “Factor of Looseness” and Estimating Cord Equivalents
A loose load of firewood typically occupies about 60-70% of the space it appears to fill. This means that if your 6-foot bed holds 52 cubic feet, a load of loose firewood will likely contain only about 31-36 cubic feet of actual wood.
- Multiply your truck bed’s cubic footage by 0.6 (for 60% fill) and 0.7 (for 70% fill).
In our example: 52 cubic feet x 0.6 = 31.2 cubic feet, and 52 cubic feet x 0.7 = 36.4 cubic feet.
To determine how much of a cord you have, divide the cubic feet of wood by 128 (the cubic feet in a cord).
- Divide your estimated cubic feet of wood by 128.
In our example: 31.2 cubic feet / 128 cubic feet/cord = 0.24 cords, and 36.4 cubic feet / 128 cubic feet/cord = 0.28 cords.
Therefore, a 6-foot bed filled level with the top rails might hold roughly 0.24 to 0.28 cords of firewood. This is a rough estimate, and it depends on several factors, which we’ll explore next.
Pro Tip #2: Wood Species, Moisture Content, and the Weight Factor
The type of wood and its moisture content dramatically affect how much weight and volume you can safely carry. Denser hardwoods like oak, maple, and hickory are significantly heavier than softwoods like pine, fir, and poplar. Wet wood is much heavier than seasoned (dry) wood.
I remember one time, I thought I was getting a great deal on a load of oak. It filled my truck bed nicely, looked like a solid half cord. What I didn’t realize was how incredibly green it was. I nearly bottomed out my suspension driving home! I learned a valuable lesson that day: always inquire about the species and seasoning of the wood.
Here’s a breakdown of approximate weights per cord for different wood types (seasoned):
- Oak: 4,500 – 5,000 lbs per cord
- Maple: 4,000 – 4,500 lbs per cord
- Hickory: 4,800 – 5,200 lbs per cord
- Beech: 4,200 – 4,700 lbs per cord
- Ash: 3,800 – 4,300 lbs per cord
- Birch: 3,500 – 4,000 lbs per cord
- Pine: 2,000 – 2,500 lbs per cord
- Fir: 2,200 – 2,700 lbs per cord
- Poplar: 1,800 – 2,300 lbs per cord

Calculating Weight in Your Truck Bed:
Let’s say you’re loading seasoned oak into your 6-foot bed, which we estimated holds about 31.2 to 36.4 cubic feet of wood (0.24-0.28 cords).
- Calculate the weight per cubic foot: Divide the weight per cord by 128 cubic feet. For oak (average 4,750 lbs/cord): 4,750 lbs / 128 cubic feet = 37.1 lbs per cubic foot.
- Multiply the cubic feet of wood in your truck bed by the weight per cubic foot: 31.2 cubic feet x 37.1 lbs/cubic foot = 1,157.5 lbs, and 36.4 cubic feet x 37.1 lbs/cubic foot = 1,350.4 lbs.
This means your 6-foot bed could be carrying between 1,157 and 1,350 pounds of oak, assuming it’s level with the bed rails.
Important Safety Note: Always check your truck’s payload capacity (listed on a sticker inside the driver’s side door) and never exceed it. Payload capacity includes the weight of passengers, cargo, and any modifications to the truck. Overloading can damage your vehicle, compromise its handling, and create a dangerous driving situation.
Pro Tip #3: Stacking Smart: Minimizing Air Gaps
The way you load the wood significantly impacts how much you can fit. Randomly tossing wood into the bed creates large air gaps. A more organized approach can increase the amount of wood you carry.
- Stack the wood tightly, aligning the pieces as much as possible. This is especially important with shorter pieces.
- Fill in gaps with smaller pieces or kindling. This helps to compact the load.
- Consider using a truck bed organizer or a tarp to help contain the load. This can prevent wood from shifting and spilling.
I’ve found that stacking the first layer neatly and then filling in the gaps as I go makes a huge difference. It takes a little more time, but it’s worth it in terms of volume and stability.
Pro Tip #4: Topping Off and Tarping: Safe and Legal Practices
While it might be tempting to pile the wood high above the bed rails, consider the safety and legal implications. Many jurisdictions have laws regarding unsecured loads.
- Secure the load with a heavy-duty tarp and tie-down straps. This prevents wood from falling out during transport.
- Avoid overloading beyond the bed rails unless you have a secure rack system. Even then, be mindful of weight limits.
- Check your local regulations regarding load securement. Fines for unsecured loads can be significant.
I always use a tarp, even for short trips. It’s not just about avoiding fines; it’s about protecting other drivers and preventing damage to my truck. A good tarp and some ratchet straps are a small investment that pays off big time.
Pro Tip #5: Know Your Vendor and Negotiate Fair Prices
The firewood market can be a bit of a Wild West. Prices vary widely depending on location, wood species, demand, and the vendor’s honesty.
- Get quotes from multiple vendors. Compare prices per cord (or rick, but be sure to clarify the dimensions of the rick).
- Ask about the wood species and moisture content. Seasoned wood should have a moisture content of 20% or less. You can use a moisture meter to check.
- Inquire about delivery fees. Some vendors include delivery in the price, while others charge extra.
- If possible, inspect the wood before you buy it. Look for signs of rot, insects, or excessive moisture.
- Negotiate the price if you’re buying a large quantity. Many vendors are willing to offer a discount for bulk purchases.
I’ve learned that building a relationship with a reputable vendor is invaluable. Find someone who is honest, reliable, and willing to answer your questions. Don’t be afraid to ask for references or check online reviews.
Understanding Firewood Pricing:
Firewood prices fluctuate based on several factors:
- Location: Urban areas generally have higher prices due to increased demand and transportation costs. Rural areas often have lower prices but may require more effort to find a reliable vendor.
- Wood Species: Hardwoods like oak, maple, and hickory command higher prices than softwoods like pine and poplar due to their higher heat output and longer burn times.
- Seasoning: Seasoned (dry) wood is more expensive than green (freshly cut) wood because it requires time and effort to dry.
- Demand: Firewood prices typically peak during the fall and winter months when demand is highest.
- Delivery: Delivery fees can add significantly to the overall cost.
- Quantity: Buying in larger quantities (e.g., a full cord) usually results in a lower price per unit.
Current Industry Benchmarks (2024):
- Average price per cord of seasoned hardwood (US): $250 – $450 (depending on location and species)
- Average price per cord of seasoned softwood (US): $150 – $300 (depending on location and species)
- Average delivery fee (US): $50 – $100 (depending on distance)

Cost Optimization Tips:
- Buy firewood in the spring or summer when prices are typically lower.
- Consider splitting your own firewood to save money. You can rent a log splitter or use a manual splitting maul.
- Season your own firewood. This requires time and space, but it can save you a significant amount of money.
- Explore alternative fuel sources, such as wood pellets or biofuel, if they are cost-effective in your area.
- Improve the energy efficiency of your home to reduce your firewood consumption.
Case Study: Comparing Firewood Costs
Let’s consider two scenarios:
Scenario 1: Buying Seasoned Oak from a Vendor
- Price per cord: $350
- Delivery fee: $75
- Truck bed capacity: 0.26 cords (average of our previous estimates)
- Cost per truck bed load: $350/cord x 0.26 cords = $91 + $75 delivery fee = $166
Scenario 2: Harvesting and Seasoning Your Own Birch
- Permit fee (for harvesting on public land): $50
- Chainsaw rental (weekend): $75
- Gas and oil: $25
- Truck bed capacity: 0.26 cords
- Labor (estimated hours): 8 hours
- Labor cost (opportunity cost, assuming $20/hour): $160
- Total cost: $50 + $75 + $25 + $160 = $310
- Cost per truck bed load (assuming you harvest 1 cord): $310 / (1 cord / 0.26 cords/truck bed) = $80.60
In this example, harvesting and seasoning your own birch is significantly cheaper than buying seasoned oak from a vendor, even when factoring in the costs of permits, rentals, and labor. However, this requires time, effort, and access to a suitable woodlot.
