Cord of Firewood Calculator

Calculate Your Firewood Needs Instantly with Our Cord of Firewood Calculator

Our Cord of Firewood Calculator is your essential tool for accurately determining the exact quantity of firewood you need for the season. Whether you’re heating your home or stocking up for campfires, this firewood volume calculator helps you avoid overspending and ensures you have enough fuel. Simply input the dimensions of your stacked wood, and our cord calculator will provide the precise volume.

How to Use the Cord of Firewood Calculator for Accurate Estimates

1. Measure Your Stack: Begin by measuring the length, height, and depth of your stacked firewood in feet.
2. Enter Dimensions: Input these measurements into the respective fields: “Stack Length (feet),” “Stack Height (feet),” and “Stack Depth (feet).”
3. Calculate Volume: Click the “Calculate” button. The wood cord calculator will instantly display the total volume in cubic feet and the equivalent number of cords.

Cord of Firewood Calculator Worked Example for 2025

Let’s say you have a stack of firewood that measures 16 feet long, 4 feet high, and 4 feet deep.

Using our firewood quantity estimator:

• Stack Length: 16 feet
• Stack Height: 4 feet
• Stack Depth: 4 feet

The calculator would determine the total volume as 16 ft × 4 ft × 4 ft = 256 cubic feet. Since one cord is 128 cubic feet, this stack contains exactly 2 cords of firewood. This helps you plan your purchases for the upcoming 2025 winter season.

Key Assumptions and Limitations of Our Firewood Volume Calculator

• Standard Cord Definition: This cord calculator uses the universally accepted definition of a cord as 128 cubic feet of stacked wood. This includes the wood itself and the air spaces between the logs.
• Stacking Method: The accuracy of the firewood quantity estimator relies on your firewood being stacked reasonably tightly and uniformly. Loosely stacked wood will contain more air and less actual wood volume.
• Wood Type & Density: While the calculator provides volume, it does not account for the weight or energy content, which varies significantly by wood species (e.g., oak vs. pine) and moisture content.
• Measurement Accuracy: The precision of the calculated cords depends directly on the accuracy of your input measurements. Always measure carefully!

Frequently Asked Questions

How many cubic feet are in a cord of firewood?

There are exactly 128 cubic feet in one cord of firewood.

The weight of a cord of firewood varies significantly depending on the type of wood (density), moisture content, and how tightly it’s stacked. For example, a cord of seasoned oak can weigh over 4,000 lbs (1,800 kg), while a cord of seasoned pine might weigh around 2,500 lbs (1,130 kg).

To measure if a stack of firewood is a cord, you need to calculate its volume. Measure the length, width (depth), and height of the stacked wood in feet. Multiply these three dimensions together. If the result is 128 cubic feet, you have a full cord. For example, a stack 8 ft long, 4 ft high, and 4 ft deep is a cord.

A cord of firewood is a standard unit of measure for stacked firewood, defined as 128 cubic feet of wood. This typically corresponds to a stack measuring 4 feet high, 4 feet deep, and 8 feet long, including the air spaces between the logs.
