Understanding how to measure firewood cord accurately is essential if youre stocking up for winter.
Most homeowners get confused by different firewood terms – full cords, face cords, ricks, stacks, and more. It is important to know that legally and commercially, wood is measured in cords.
In this beginner’s guide, we will discuss everything you need to know, such as standard firewood cord dimensions, the difference between a full cord and a face cord, and the correct way to calculate firewood volume so you know exactly what you’re buying, selling, or stacking
What is a Cord of Firewood?
A cord is the standardized measurement of firewood volume that is used across the United States.
A full cord is measured 4 feet high x 4 feet deep x 8 feet long.
This makes the total volume: 128 cubic feet.
This measurement applies regardless of how you cut the wood, though the depth refers to the combined length of the logs placed front to back rather than the length of the individual logs.
Full Cord vs. Face Cord: What’s the Difference?
Most homeowners assume that a face cord is the same as a full cord; however, that is not true.
Full Cord (Standard Cord)
- Measures 128 cubic feet
- 4 ft high x 4 ft deep x 8 ft long
- Contains three rows of 16-inch logs
face Cord
A face cord only measures the front-facing length and height of a cord.
- 4 ft high, 8 ft long, but only one log deep.
- The depth depends on the log length
In other words, a face cord is roughly one-third of a full cord.
Firewood Cord Dimensions Explained
To accurately measure firewood, you must understand how dimensions translate into volume.
For a full cord: 4 ft x 4 ft x 8 ft = 128 cibic ft
For a face cord: 4 ft x 1.3 ft x 8 ft = 41 cubic ft
In conclusion, the length has a significant impact on the total volume of the cords. This is why knowing the exact measurements is an important step.
How to Calculate Firewood Volume Correctly
Here’s a simple guide on how you can easily calculate the volume of your firewood.
Step 1: Measure the Length of the Stack
Use a tape measure and make sure the wood is stacked in a straight, consistent line.
Step 2: Measure the height
The stack should be an even height. If it has a slope, measure at various points and average the values.
Step 3: Measure the Depth
This should be the combined length of the logs.
Step 4: Multiply to Get Cubic Feet
Multiply the logs as explained above.
Step 5: Compare to a Full Cord
Full cord = 128 cubic feet
Your stack / 128 = % of a cord
How to Tell if You’re Receiving a Full Cord
Here’s how you can verify you’re getting the correct amount if youre buying firewood only.
Be Specific About Dimensions
A reputable seller like 12 Point Farms LLC will provide:
- Length of logs
- Size of the stack of files
- Specify if it’s a full cord or a partial cord
Measure the Pile Before and After Stacking
Delivered wood is usually dumped in a loose pile, which takes up more space and cannot be measured accurately until stacked. After stacking, How To Measure Firewood Cord by following the steps above.
Count the Rows
If logs are 16 inches, then that means:
- 1 rows = face cord
- 3 rows = full cord
Watch for Uneven Stacks
A neatly stacked cord has straight edges, a consistent heght, and tight rows with good airflow. If the stack slopes or leans, the volume may be reduced.
How to Measure Firewood Cord: How Many Do You Need for Winter?
Your usage depends on factors such as home size, stove or fireplace requirements, insulation, wood type, and climate.
As a general guideline:
- Primary heat source: 3 – 5 full cords.
- Supplemental heating: 1 – 2 full cords.
- Occasional fires: ½ – 1 cord
With proper moisture content (20% or less), you can increase burn efficiency, which means you’ll use fewer cords over the winter.
How to Measure Firewood Cord and Stack It Correctly
Here are some helpful guidelines on How To Measure Firewood Cord stack a full cord correctly for improved airflow and accuracy.
- Stack on a raised surface.
- Maintain good airflow
- Keep the rows straight
- Use stable end pillars
- Cover only the top
