Formula & worked example

Volume (cu ft) = length x width x height converted to feet. Full cords = volume / 128. Face cords (16 in logs) = volume / 42.667.

A stack 8 ft long, 4 ft deep and 4 ft high is exactly 1 full cord, or 3 face cords with 16-inch logs.

Limitations — read this before you rely on it

Stacked volume only; it does not measure solid wood content, moisture, species, or heating value, and face-cord figures assume 16-inch log length.

Frequently asked questions

128 cubic feet of stacked firewood, traditionally a pile 4 ft high, 4 ft deep and 8 ft long, including the air between logs.

A single row of a cord: an 8 x 4 ft face with the log length as depth. With 16-inch logs it is one third of a full cord.

Because a face cord fixes the face area but not the depth; longer logs hold more wood per face cord.

No. Stacked cords include air gaps, typically 20 to 30% of the volume, so solid wood content is less than 128 cubic feet.

Yes, terms like rick or truckload vary by region and are not standard; always confirm cubic feet.
