Firewood Calculator Measure Cords, Costs & Wood Fast
🔥 Firewood Calculator
Estimate your firewood needs and convert between volume measurements
- Firewood is the primary or supplemental heat source
- You have a reasonably insulated space
- Wood is burned in a typical fireplace or wood stove
- Insulation quality and air leaks in your home
- Stove/fireplace efficiency (15% for open fireplaces, up to 90% for modern stoves)
- How often you run the heating system
- Your personal comfort preferences and burning habits
- Actual winter temperatures in your area
- Full Cord: 4 ft (height) × 8 ft (length) × 4 ft (depth) = 128 cubic feet of solid stacked wood
- Face Cord: 4 ft (height) × 8 ft (length) × 16 in (depth) = 32 cubic feet. Also called a “stove cord” or “short cord”
- Rick: 4 ft (height) × 8 ft (length) × 16 in (depth) = 16 cubic feet. Regional usage varies; confirm locally before purchasing
- Cubic Feet/Meter: Direct volume measurements with no specific stacking configuration
Use this firewood calculator to estimate how much firewood you have stacked in your yard, whether you want the amount in standard cords or the smaller face cord measurement. Enter your local price per cord, and the calculator can also estimate the total value of your firewood stack.
For anyone new to firewood measurements, a Free firewood calculator app can make the process easier while helping you understand the standard dimensions of a full cord. You’ll also learn exactly how much space a cord of wood typically occupies, so you can measure your stack with confidence.
How to Use This Cord of Wood Calculator?
Using the cord of wood calculator is straightforward. Enter the measurements you have, and it will work out the number of cords in your firewood stack for you.
- If you know the length, width, and height, enter each measurement in the first three rows. You can also click the unit selector and switch to the unit that matches your measurements.
- Already have the volume of your wood stack? Enter it directly into the calculator’s volume field instead.
- The calculator will show the number of full cords of wood and also indicate how much of a complete cord your stack represents as a percentage.
- To calculate a face cord, enter the width of your stack as 16 inches. Make sure the width unit is set to inches before entering the value.
- The result will include the number of face cords as well as the percentage of one full face cord.
- To find out how much your entire stack is worth, simply enter the price per cord.
How to Calculate a Cord of Firewood
To work out how many cords are contained in a stack of firewood, multiply its length, width, and height in feet, then divide the result by 128 cubic feet. The standard formula is:
number of cords = (length (ft) × width (ft) × height (ft)) / 128 ft³
A Woodworking firewood calculator can simplify this calculation when you’re working with different stack measurements. For measurements in metres, you can use the SI-based formula instead:
number of cords = (length (m) × width (m) × height (m)) / 3.6246 m³
For example, imagine a large stack of wood measuring 15 feet (4.57 m) long, 6 feet (1.83 m) deep, and 7 feet (2.13 m) high. Entering these measurements into the formula gives:
number of cords = (15 × 6 × 7) / 128 = 4.9 cords
A Log cord calculator can also help you get the cord quantity quickly when you have the dimensions of a stacked pile ready to use.
What Is a Cord of Wood? How Much Wood Is in a Cord?
So, what exactly is a cord of wood? It is a unit of volume used to measure firewood and pulpwood when logs are stacked in uniform lengths with as little space as possible between them. One full cord measures 8 feet (2.44 m) long, 4 feet (1.22 m) wide, and 4 feet (1.22 m) high, giving a total volume of 128 cubic feet (3.62 m³).
A Free firewood calculator can make these measurements easier to work with when estimating the amount of wood in a stack. Likewise, a Firewood calculator pro can be useful when you need to understand cord measurements and calculate the volume of firewood more conveniently.
The term “cord” is believed to come from the piece of cord or string traditionally used to measure a stack of logs.
Knowing what the dimensions of a cord of wood are makes it much easier to measure your firewood correctly, especially if you’re not familiar with this unit of volume.
What Is a Face Cord of Wood?
When firewood is stacked using the standard 16-inch-long logs and the pile is only one log deep, it is known as a face cord of wood. This type of stack measures 8 feet (2.44 m) long, 16 inches (40.6 cm) deep, and 4 feet (1.22 m) high—roughly the amount you might see stacked beside a log cabin.
A Cord of wood calculator square feet can help when you’re working with stack dimensions, while a Firewood cubic feet calculator can be useful for estimating the total volume of the pile. In terms of quantity, a face cord contains one-third of the firewood found in a full cord.
What Is the Formula for a Face Cord of Firewood?
The calculation for finding the number of face cords is much like the standard cord formula, but the stack depth is fixed at 16 inches, or 1 ⅓ feet. Use the following formula:
number of face cords = (length (ft) × 1 ⅓ (ft) × height (ft)) / 42.67 ft³
When working with measurements in metres, the equivalent SI formula is:
number of face cords = (length (m) × 0.406 (m) × height (m)) / 1.208 m³
For example, suppose you have a stack of standard-length firewood outside a log cabin. If the stack is 7 feet (2.134 m) long and 4 feet (1.219 m) high, the calculation would be:
number of face cords = (7 × 1 ⅓ × 4) / 42.67 = 0.875 face cords

Conclusion
Knowing how cords, face cords, and firewood volume measurements work makes it easier to estimate your supply, compare quantities, and understand the value of your stack. By entering the right measurements into the calculator, you can quickly determine your firewood amount and plan your next purchase with greater confidence.
