Buying and stacking firewood can be confusing, especially when trying to figure out how much wood you’re actually getting. A cord of wood is the standard measurement used in firewood sales, but understanding what it means and how to calculate it can save you money and frustration. This guide will walk you through what a cord of wood is, how to measure it, and how to calculate the amount of firewood you need for your home or business.
What is a Cord of Wood?
A cord is a unit of measure for firewood that equals 128 cubic feet of tightly stacked wood, including air spaces between logs. This standard measurement ensures you’re getting a consistent amount of firewood when purchasing.
Dimensions of a Full Cord:
- 4 feet high x 4 feet wide x 8 feet long (4x4x8).
Types of Firewood Cords
- Full Cord: The standard measurement of 128 cubic feet.
- Face Cord: A stack of wood that measures 4 feet high and 8 feet long, but the depth of the stack is usually around 16 inches (a third of a full cord).
- Rick: Another term for a face cord, but the depth can vary depending on the region.
- Half Cord and Quarter Cord. Fractions of a full cord for more minor needs or limited storage space.
How to Measure a Cord of Wood
To ensure you’re getting what you pay for, it’s essential to measure the wood stack yourself:
- Height: Measure the stack from the ground to the top.
- Width: Measure the length of the stack across its front face.
- Depth: Measure the length of the logs from front to back.
- Calculate: Multiply height x width x depth in feet to find the cubic footage.
Example:
A stack that’s 4 feet high, 8 feet long, and 2 feet deep is:
4 x 8 x 2 = 64 cubic feet, which is half a cord.
Cord of Wood Calculator Formula
If your stack doesn’t follow standard dimensions, use this formula to calculate how much wood you have:
(Height in feet) x (Width in feet) x (Depth in feet) ÷ 128 = Number of cords
Example:
A pile that’s 6 feet high, 10 feet wide, and 2 feet deep:
6 x 10 x 2 = 120 cubic feet.
120 ÷ 128 = 0.9375 cords (just under a full cord).
How Much Wood Do You Need?
The amount of firewood you need depends on your heating setup, climate, and how often you burn wood:
- For Home Heating. An average household using wood as a primary heat source may need 4 to 6 cords per winter in colder climates.
- For Occasional Fires. If you’re burning wood recreationally in a fireplace or fire pit, a single cord can last an entire season.
- For Cooking or Smoking. Smaller amounts like a face cord or quarter cord are usually sufficient.
Tips for Buying and Stacking Firewood
- Buy Early: Firewood is cheaper in spring and summer when demand is low.
- Season the Wood: Ensure your wood is seasoned properly (moisture content below 20%) for efficient burning.
- Stack for Airflow: Stack logs off the ground with space between rows to allow proper drying.
Common FAQs About Firewood Cords
How many pieces of wood are in a cord?
A cord typically contains 300 to 400 pieces, depending on the size of the logs.
How much does a cord of wood cost?
Prices vary by region and type of wood but typically range from $150 to $600.
What’s the difference between a face cord and a full cord?
A face cord is about one-third of a full cord, as it’s typically only 16 inches deep.
Can I stack wood in any shape to measure it?
No. For accurate measurement, firewood should be stacked tightly in a straight, rectangular pile.
360 Key Takeaways
- A full cord of wood equals 128 cubic feet (4x4x8 feet).
- Use the formula (Height x Width x Depth) ÷ 128 to calculate the volume in cords.
- Buying firewood in cords ensures you’re getting a consistent and fair amount.
- Seasoned wood and proper stacking ensure efficient burning and long-lasting fires.
