How to use the Firewood / Cord Calculator

  1. Enter the requested field, crop, animal, equipment, or cost information.
  2. Keep every value in the unit shown beside its field.
  3. Select Calculate and review each result and assumption.
  4. Verify important decisions with local records, labels, extension guidance, or a qualified adviser.

Formula and method

Stacked volume = length × height × depth × number of stacks. Full-cord equivalent = stacked volume ÷ 128 ft³.

The calculator uses stacked external dimensions. A full cord is defined as 128 cubic feet of stacked firewood; for example, 4 ft × 4 ft × 8 ft.

Worked example

One 8 ft × 4 ft × 4 ft stack has 128 ft³ of stacked volume, equal to one full-cord equivalent.

Understanding the result

Treat the calculated values as a planning estimate. Compare them with your field records, product information, local conditions and operational capacity before acting.

Important: Local sales rules and terminology can differ. Terms such as face cord or truckload are not universally standardized; verify the legal selling unit and stack dimensions in your jurisdiction.

Frequently asked questions

How many cubic feet are in a full cord of firewood?

A full cord is 128 cubic feet of stacked firewood. A 4 ft × 4 ft × 8 ft stack is one example of dimensions that equal 128 cubic feet.

How do I calculate cords from a wood stack?

Multiply stack length, height and depth, multiply by the number of identical stacks, then divide the stacked cubic feet by 128.

Is a face cord the same as a full cord?

Not necessarily. Terms such as face cord can vary by locality and are not universally standardized, so verify the actual stack dimensions and local selling rules.

Does the calculator measure solid wood volume?

No. It calculates external stacked volume, which includes the air spaces between pieces of firewood.
