When it comes to heating your home with firewood, one of the most important aspects is understanding how much wood you’re buying or stacking. That’s where a Cords of Wood Calculator comes in handy. This powerful tool helps you determine the number of cords in a given stack of firewood and even calculates the total cost based on the price per cord. Whether you’re a homeowner preparing for winter or someone working in the firewood industry, this calculator will simplify your planning.
What is a Cord of Wood?
A cord is a standardized unit of measure used to quantify firewood. One full cord is defined as a neatly stacked pile of wood that measures 4 feet high, 8 feet long, and 4 feet deep, totaling 128 cubic feet.
This unit ensures consistency in firewood measurement and helps buyers and sellers communicate clearly about the volume being exchanged. However, not all firewood stacks come in perfect cord-sized dimensions, which is why a calculator is useful.
What is the Cords of Wood Calculator?
The Cords of Wood Calculator is a digital tool that allows users to enter the dimensions of a woodpile — height, width, and length in feet — and the cost per cord, to calculate:
- The number of cords in the stack.
- The total cost based on the provided price per cord.
This calculator eliminates the guesswork and manual calculations involved in estimating firewood volume and cost.
How to Use the Cords of Wood Calculator
Using the calculator is simple. Follow these steps:
- Input the dimensions of your woodpile:
- Height (in feet)
- Length (in feet)
- Width (in feet)
- Enter the cost per cord (in dollars).
- Click on “Calculate” to get:
- The number of cords.
- The total cost based on your input price.
Formula Used in the Calculator
The calculator uses a straightforward formula:
Cords = (Length × Width × Height) / 128
Where:
- Length = length of the woodpile in feet
- Width = width of the woodpile in feet
- Height = height of the woodpile in feet
- 128 = the number of cubic feet in one full cord of wood
Total Cost = Cords × Cost per Cord
These equations allow for quick and accurate calculations for any stack size.
Example Calculation
Let’s say you have a stack of wood that measures:
- Height = 4 feet
- Width = 4 feet
- Length = 8 feet
- Cost per cord = $150
Step 1: Calculate cords
Cords = (8 × 4 × 4) / 128 = 128 / 128 = 1 cord
Step 2: Calculate total cost
Total Cost = 1 × $150 = $150
So, this stack contains 1 full cord and would cost $150.
Why Use the Cords of Wood Calculator?
Here are a few reasons why this tool is a must-have:
Saves time compared to manual calculations.- Avoids overpaying or underestimating wood volumes.
- Useful for buyers and sellers in the firewood trade.
- Great for home budgeting during the heating season.
- Helps compare suppliers based on cost per cord.
Important Considerations
1. Accurate Measurements Matter
Ensure you measure the actual stack, including gaps between logs. A loosely stacked pile may occupy more space than tightly packed wood.
2. Stacking Method Affects Volume
Stacking in criss-cross or haphazard ways may increase the air volume and reduce the real wood volume, leading to lower cord estimation.
3. Face Cord vs Full Cord
Be aware of the difference:
- A full cord is 128 cubic feet.
- A face cord is usually 4 feet high by 8 feet long but with shorter logs (e.g., 16 inches deep), which is only one-third of a full cord.
This calculator assumes you’re measuring the entire volume of the stack.
Benefits of Buying by the Cord
- Standardization: Avoids confusion.
- Transparency: Buyers know what they’re paying for.
- Better pricing: Sellers can set fair, competitive rates.

20 Frequently Asked Questions (FAQs)
1. What is a cord of wood?
A cord is 128 cubic feet of neatly stacked firewood, measuring 4 ft high × 8 ft long × 4 ft deep.
2. How do I measure a woodpile for the calculator?
Measure the height, width, and length in feet using a tape measure.
3. What unit should I use in the calculator?
Use feet for all dimensions and U.S. dollars for the cost.
4. Is the calculator accurate for any type of wood?
Yes, it calculates volume regardless of wood type.
5. Does wood density affect the calculation?
No, this calculator only measures volume, not weight.
6. What if I have multiple stacks?
Calculate each stack separately and sum the results.
7. Can I use this for stacked logs or split wood?
Yes, as long as the pile is measured in feet.
8. What’s the difference between a face cord and full cord?
A face cord is typically one-third the size of a full cord.
9. Why divide by 128 in the formula?
Because one full cord equals 128 cubic feet.
10. How can I reduce the total cost?
Buy in bulk or find local suppliers offering discounts.
11. Is the cost per cord fixed?
No, it varies by region, wood type, and season.
12. Can I calculate cost in different currencies?
You can, but you must manually convert the currency.
13. What happens if I enter zero or negative values?
The calculator will return 0 cords and 0 cost.
14. Is this tool mobile-friendly?
Yes, it works on most modern smartphones and tablets.
15. Can this calculator help with budgeting firewood?
Absolutely. It helps you forecast winter fuel expenses.
16. Is stacking tightly important?
Yes, tight stacking ensures accurate measurement.
17. Can I round the dimensions?
For rough estimates, yes. For precision, measure to the nearest inch and convert to feet.
18. Can I use this for metric measurements?
No, this version only supports feet. Use a converter before inputting values.
19. Is this calculator free?
Yes, it’s a free tool provided for public use.
20. Can I embed this calculator on my own site?
You’d need the code or embed script to do that. Ask the tool developer.
