What Size Is a Cord of Wood? This Extreme Guide Will Blow Your Mind!
If you’ve ever wondered “What size is a cord of wood?”—you’re not alone. Whether you’re heating your home, powering a wood-burning stove, or stockpiling fuel, understanding the exact dimensions of a cord transforms how you buy, store, and use wood. This extreme guide breaks down everything about a cord of wood—from standard measurements to surprising facts that will completely change your perspective!
The Official Size: A Cord Is Exactly 48 Cubic Feet
Understanding the Context
By definition, one cord of wood equals 48 cubic feet—a precise measurement that applies everywhere in the U.S. and widely adopted internationally. To visualize it: reimagine a rectangular prism measuring 4 feet long, 4 feet wide, and 3 feet high (4 × 4 × 3 = 48 ft³). That’s the classic cord size. It’s not arbitrary—this standardization ensures clarity for buyers and sellers alike.
Origin of the Measurement: More Than Just Numbers
The term “cord” dates back to lumberjacking days when workers literally measured logs piled in heaps by volume, not weight or bagged volume. A cord standardized supply trades, avoiding confusion over irregular pile shapes. Even as logging evolved, the cubic foot benchmark persisted, offering simplicity and consistency across markets.
Why 48 Cubic Feet? The Math Behind the Cord
Key Insights
Why 48? Because 48 arises cleanly from fundamental geometry. A full cord volume corresponds to:
- 4 feet × 4 feet × 3 feet = 48 cubic feet
- Or alternatively: 4 ft × (4 ft × 3 ft) = 48 ft³ (same result!)
- Log spacing, stacking efficiency, and Australian/Imperial conversions all converge on this number.
This precise formula removes guesswork—no need to estimate loose stacks or awkward pile sizes. 48 ft³ is reliable, repeatable, and universally recognized.
But Wait—Cord Measurements Vary by Region (And That’s Not a Mind-Blower Yet!)
While 48 ft³ is the U.S. standard, what counts as “one cord” differs globally, surprising even seasoned firewood users:

| Country/Region | Equivalent to One Cord |
|------------------|----------------------------------|
| U.S. (U.S., Canada)| 48 cubic feet |
| Australia | 45 feet (1.36 m) high × 4 ft × 4 ft = ~45 ft³ (slightly less volumetric) |
| UK (approx.) | ~48.5 cubic feet (slight premium) |
Wait, 45 vs. 48 ft³? Yes. Due to stacking height and compression, international volumes can vary by up to 3–5%. But the 48 ft³ U.S. cord remains the industry gold standard for contracts, shipments, and inventory.
Cord Types: Cubic Feet vs. Live Weight (But Size Remains 48 ft³ Regardless!)
Crucially, while cord weight fluctuates—hardwood vs. softwood, moisture content, and drying status—the volume stays fixed at 48 cubic feet. How?
- Cubic foot cord measures empty volume—ideal for shipping and storage planning.
- “Bushel cord” or “FIBC” (Forest Products Commission cord) typically equals 48 ft³ but often refers to live, split wood (logs, cords split for firewood).
- “Cored cord” accounts for wood core density, reducing volume slightly, but standard cords assume minimal compaction.
Key Takeaway: Size = Volume, Not Logic—Cords Are Always 48 ft³ by Design
Even when core, green, or split wood slightly reduces total weight, the measurement remains 48 ft³. The cord’s size is about space—how much room your fuel occupies—not weight or moisture.
Why Does Knowing This Size Matter? Big Implications!
Mastering the cord’s exact dimensions opens doors:
1. Accurate Shopping
Avoid overpaying for “bulk” by confirming you’re getting a true 48 ft³. Many sellers mislabel smaller, irregular piles as “full” cords.
