Buy a Cord of Wood
When you buy a cord of wood to heat your home during winter, understanding exact firewood volumetric measurements, moisture content, and wood species is critical to avoid being shortchanged by unscrupulous sellers. A legal full cord of firewood is a precisely defined statutory measurement: a tightly stacked pile of wood measuring exactly 128 cubic feet (typically 4 feet high, 4 feet deep, and 8 feet long). Learning how to inspect moisture levels, calculate stack volume, and differentiate seasoned hardwood from green wood guarantees safe, efficient winter heating.
The Legal Definition of a Cord vs. Face Cords, Ricks, and Truckloads
In consumer weights and measures statutes across the United States and Canada, the only legally recognized term for selling bulk firewood is the full cord. A legal cord represents a tightly stacked pile of split wood measuring 128 cubic feet, traditionally arranged in a stack 4 feet high by 8 feet long by 4 feet deep (or three rows of 16-inch split logs stacked 4 feet high by 8 feet long). Any seller offering vague terms like 'truckload,' 'pile,' or 'rick' without specifying cubic footage is often selling significantly less wood.
A common regional term is the 'face cord' (often called a 'rick' in the Midwest and South). A face cord consists of a single row of split wood stacked 4 feet high and 8 feet long. Because fireplace logs are typically cut to 16 inches long, a face cord represents only one-third of a true full cord (roughly 42.6 cubic feet of wood). Uninformed consumers who pay full-cord prices for a single face cord are overpaying by nearly 300%.
Compare common firewood sales measurements and true cubic volume equivalents:
| Firewood Measurement Term | Physical Stack Dimensions | Actual Total Cubic Volume | Fraction of a Full Legal Cord | Legal Commerce Status |
|---|---|---|---|---|
| Full Legal Cord | 4 ft High x 8 ft Long x 4 ft Deep | 128.0 Cubic Feet | 1.00 Full Cord | Legally recognized standard unit |
| Face Cord / Rick (16-in logs) | 4 ft High x 8 ft Long x 16 in Deep | 42.6 Cubic Feet | 0.33 of a Full Cord | Informal regional term; not a legal cord |
| Face Cord (24-in logs) | 4 ft High x 8 ft Long x 24 in Deep | 64.0 Cubic Feet | 0.50 of a Full Cord | Informal regional measurement |
| Standard 8-ft Pickup Bed (Level) | Level with truck bed rails | 60 to 70 Cubic Feet (Loose) | 0.45 to 0.55 of a Cord | Requires stacking to verify volume |
| Short-Bed 6-ft Pickup Bed (Level) | Level with truck bed rails | 40 to 45 Cubic Feet (Loose) | 0.30 to 0.35 of a Cord | Roughly equal to a single face cord |
Seasoned Hardwood vs. Green Wood: Moisture Content Science
Burning green or improperly seasoned firewood is dangerous, inefficient, and damaging to home heating appliances. Freshly felled green wood contains roughly 45% to 60% internal moisture content by weight. When burned in a wood stove or fireplace, tremendous amounts of heat energy are wasted boiling off trapped water, resulting in low flame temperatures, dense smoldering smoke, and rapid accumulation of combustible creosote inside your chimney flue.
Properly seasoned firewood must achieve an internal moisture content of 15% to 20%. Seasoning requires splitting logs and stacking them off the ground in a sunlit, windy location covered on top for 6 to 18 months. Seasoned wood displays gray, weathered bark, dark radial cracks on the cut log ends, feels noticeably lighter in hand, and rings with a hollow musical 'clack'—like bowling pins striking—rather than a dull thud when two pieces are banged together.
Compare popular firewood species across heat output (BTUs) and burning characteristics:
| Wood Species Classification | Heat Output (Million BTUs/Cord) | Splitting Ease | Spark & Smoke Level | Coaling Ability |
|---|---|---|---|---|
| Hickory / Black Locust | 27.5 to 28.5 Million BTUs | Difficult (Dense grain) | Low sparks, very clean burn | Exceptional overnight hot coals |
| White Oak / Red Oak | 25.5 to 26.5 Million BTUs | Moderate | Very low sparks, pleasant aroma | Superior long-lasting coal bed |
| Hard Sugar Maple | 24.0 to 25.5 Million BTUs | Moderate | Low sparks, clean hot burn | Excellent sustained winter heat |
| White Ash | 23.5 to 24.5 Million BTUs | Easy (Straight grain) | Low sparks, low smoke | Great; burns reasonably well even if green |
| Black Cherry | 20.0 to 21.0 Million BTUs | Easy | Moderate sparks, sweet fragrance | Good for evening ambiance fires |
| Douglas Fir / White Pine | 15.0 to 18.0 Million BTUs | Very Easy | High sparks, fast crackle | Poor coals; best for kindling starter |
Delivery Inspection, Stacking Verification, and Consumer Rights
When a firewood dealer delivers a cord of wood, never pay in cash until you have conducted an initial inspection. Inspect a random sample of logs using an inexpensive digital pin-type moisture meter. Split a large log in half with an axe and press the metal pins firmly into the center of the freshly exposed interior grain; if the meter reads above 22%, the wood is not fully seasoned.
Furthermore, bulk firewood dumped into a loose pile in your driveway cannot be measured accurately. State departments of agriculture and consumer protection advise consumers to specify in their purchase agreement that payment will be finalized once the wood is stacked. Stack the wood tightly in parallel rows with bark facing upward; measure height, length, and width to verify the total volume equals 128 cubic feet before handing over payment.
Examine common firewood buying scams and smart consumer counter-measures:
| Firewood Seller Scam | Financial / Safety Risk | Consumer Protection Action |
|---|---|---|
| Selling loose dumped truck bed as a full cord | Delivers only 60 to 75 cu ft, shorting half a cord | Stack wood tightly in rows and calculate cubic feet (HxWxL) |
| Selling semi-green wood as seasoned | Severe creosote chimney buildup; low heat | Test freshly split log centers with digital moisture meter (<20%) |
| Mixing rotten punk wood into the pile | Soft, punky wood burns instantly with zero BTUs | Reject logs that crumble, flake, or show fungus growth |
| Cutting logs to irregular lengths (12 to 24 in) | Logs will not fit into standard wood stove firebox | Specify uniform 16-inch log lengths in order agreement |
How to Inspect, Measure, and Store a Cord of Firewood
Follow these five steps to verify firewood quality and stack your cord for optimal winter burning.
Order Seasoned Hardwood Months in Advance
Place your firewood order in spring or mid-summer to ensure wood has ample drying time before winter cold sets in.
Test Internal Moisture Content with a Meter
Split a test log in half and insert a digital pin meter into the center grain; verify moisture content is below 20%.
Stack Wood Tightly and Calculate Total Volume
Stack wood off the ground in straight rows; multiply stack height, length, and depth in feet to confirm 128 cubic feet.
Elevate Stack on Pallets or Runners
Keep bottom log rows elevated 3 to 4 inches off damp soil using wooden pallets, pressure-treated 2x4s, or cinder blocks.
Cover the Top Only Leaving Sides Open
Drape a tarp or metal roofing over the top of the stack to shed rain while leaving the sides open for continuous air drying.
Frequently Asked Questions (8 Questions Answered)
Q1: How big is a legal cord of wood?
A legal full cord of wood is a tightly stacked pile measuring exactly 128 cubic feet, traditionally arranged as 4 feet high, 4 feet deep, and 8 feet long.
Q2: What is the difference between a cord and a face cord?
A full cord contains 128 cubic feet, while a face cord (or rick) is a single 4x8 foot row of 16-inch logs, equaling roughly 42.6 cubic feet (one-third of a full cord).
Q3: How much does a cord of seasoned hardwood weigh?
A full cord of seasoned oak or hickory weighs between 3,500 and 4,500 pounds, whereas green unseasoned wood can weigh over 5,500 pounds due to water content.
Q4: How can you tell if firewood is seasoned without a meter?
Seasoned wood has gray weathered bark, deep cracks in the end grain, feels light, and makes a crisp, resonant clacking sound when two pieces are struck together.
Q5: How long does a cord of wood last in winter?
A household heating exclusively with a modern wood stove typically burns 3 to 5 full cords per winter, while occasional evening fireplace use consumes roughly 1 cord.
Q6: Can you burn unseasoned green wood in an emergency?
Burning green wood is not recommended; it produces low heat, excessive smoke, and dangerous creosote glaze on chimney walls that causes chimney fires.
Q7: How long does oak take to season?
Dense hardwoods like red and white oak take 12 to 24 months to properly season down to below 20% internal moisture content.
Q8: Should you cover a cord of firewood completely with a tarp?
No, covering the entire stack traps ground moisture and creates mold; cover only the top of the stack to shed rain, leaving the sides open for air circulation.
