Firewood Stack Volume

Width × height × depth gives the stacked volume. One cord, the traditional trading unit, is about 3.62 m³. Stacked volume includes air gaps, so solid wood is around 70% of it.

Formula

Firewood volume = Length × Width × Depth

Freshly cut wood is half water by weight. It needs six months to a year of seasoning to drop below 20% moisture before it burns well.

Frequently asked questions

Q. How is Firewood Stack Volume calculated?

Firewood volume = Length × Width × Depth — Width × height × depth gives the stacked volume. One cord, the traditional trading unit, is about 3.62 m³. Stacked volume includes air gaps, so solid wood is around 70% of it.

Q. Can you walk through an example?

With Length 2.4m, Width 1.2m, Depth 0.5m, the answer is Firewood volume 1.44m³.

Q. What do I need to enter?

Enter Length, Width, Depth. The result recalculates as you type, and an empty box counts as zero.

Q. How much does the answer move if I change a number?

Changing only Length (m) moves the answer to Length (m) 1.2 → Firewood volume (m³) 0.72 and Length (m) 4.8 → Firewood volume (m³) 2.88. The table below lays out five steps.

Q. How are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

Q. Anything to watch out for?

Freshly cut wood is half water by weight. It needs six months to a year of seasoning to drop below 20% moisture before it burns well.
