A conventional full cord of wood is 128 cubic feet of stacked firewood, commonly shown as a stack 4 feet high, 8 feet long and 4 feet deep. That volume includes the wood, bark and normal air spaces between the pieces. Minnesota uses more specific cord definitions for wood that has been sawed or sawed and split, so check the preparation, measurement and written quantity before ordering.
A cord measures volume. It doesn’t tell you exactly how many logs you’ll get or how long your fires will burn. Knowing what that measurement tells you makes it easier to compare quantities and choose an amount that fits your plans.
What Are the Dimensions of a Cord of Wood?
The familiar 4-by-8-by-4-foot stack adds up to 128 cubic feet: height × length × depth. A stack can have a different shape and still hold the same volume. To measure a cord of wood, you need all three dimensions of a properly arranged stack, rather than just judging its size from the front.
Depth is easy to overlook, especially when the wood is cut into shorter pieces. Three rows of 16-inch pieces make a combined depth of 48 inches, or 4 feet. One row has much less volume, even if it looks just as tall and long. The NCWM firewood facts sheet illustrates the conventional full-cord measurement.
How Minnesota Defines a Cord of Wood
For a Minnesota purchase, take a closer look at the state’s definitions. Minnesota Statutes, section 239.33, lists these cord volumes:
- Wood cut in four-foot lengths: 128 cubic feet.
- Sawed wood: 110 cubic feet when ranked, or 160 cubic feet when loosely thrown for delivery.
- Sawed and split wood: 120 cubic feet when ranked, or 175 cubic feet when loosely thrown for delivery.
Ranked means the pieces are stacked parallel to one another. The same wood takes up a different amount of space when it’s loosely piled rather than neatly stacked, so the two arrangements use different measurements. Avoid using a loose truckload’s outside dimensions as though they were a neatly stacked quantity.
When comparing an order, keep the conventional 128-cubic-foot illustration separate from these Minnesota definitions. Ask the seller to specify the quantity and how it is measured. Minnesota Commerce’s firewood guidance explains the state’s measurements and what to check when buying.
Full Cord, Half Cord and Face Cord: What’s the Difference?
Using the conventional 128-cubic-foot illustration, half the volume is 64 cubic feet. A stack 4 feet high, 8 feet long and 2 feet deep is one way to picture that amount. For an actual purchase, check the seller’s written quantity and the measurement definition that applies to that order.
A face cord usually describes the front of a stack with a depth equal to one piece of firewood. For example, a 4-foot-high, 8-foot-long row of 16-inch pieces occupies about 42.7 cubic feet. That is one-third of the conventional 128-cubic-foot example. Longer pieces occupy more volume, which is why the words “face cord” alone don’t tell you how much wood you’re getting.
Minnesota Commerce notes that informal terms such as face cord, rick and truckload have no legal definition. Rather than assuming those names mean the same thing from every seller, ask for dimensions or a clearly stated quantity. Shortening pieces helps them fit an appliance; it doesn’t multiply the amount of wood.
How to Measure a Stack of Firewood
Start with a stack whose pieces are arranged parallel to one another. Then, multiply its height, length and depth. Make sure every measurement is in feet before calculating. If you have several rows, measure each row and add their volumes.
For a row 4 feet high and 8 feet long with 16-inch pieces, convert the depth first: 16 ÷ 12 = about 1.333 feet. Then calculate 4 × 8 × 1.333 = about 42.7 cubic feet. That gives you the row’s volume; it doesn’t automatically tell you how many Minnesota legal cords it represents.
To work out how that volume translates into a cord of wood for a Minnesota purchase, use the definition that matches both the wood’s preparation and its arrangement. Commerce provides the corresponding formulas. Check that you and the seller agree on the measurement, and keep a receipt or delivery record showing the quantity.
How Much Firewood Should You Order?
Start with what you plan to do with the wood. An occasional fire and regular wood heating call for different amounts. Think about how often you burn, your appliance and the storage space you have ready.
There’s no dependable number of logs in every cord of wood. Piece thickness and length vary, and volume includes air spaces. There’s also no universal number of hours or winter months that a cord will last. A single fixed-duration estimate isn’t a reliable way to choose your entire heating supply.
If you’re unsure, tell the seller how you plan to use the wood when you ask about quantities. ProCut’s standard log length is 16 inches. Check your appliance’s permitted log length before ordering and ask about available options if that size doesn’t fit.
Before ordering a larger quantity, make sure you have room for it. Measure the space you can use, and compare it with the amount you plan to buy. The goal is an order that fits your storage and usage, rather than the largest cord of wood available.
Questions to Ask Before Buying Firewood
Before purchasing a cord of wood, use these questions to make the order clear:
- What quantity am I buying, and how is that quantity measured?
- What is the log length, and will it fit my appliance?
- Will the wood arrive loose or stacked, and is stacking included?
- What preparation and wood type are included in this order?
- Will the written receipt or delivery record show the agreed quantity?
For Minnesota purchases, Commerce recommends getting the seller’s business information and a receipt showing the amount and agreed type of wood. Settling those details before delivery makes it easier to compare orders than relying on a label such as “truckload”.
