Measure your firewood stack in feet and the log length in inches to see how much of a 128 cu ft cord you have, if you were shorted, and the price per cord.

Good to know: Scope: how much firewood is in a neatly stacked pile, measured in cubic feet, cords and cubic meters, with an optional check against the amount you paid for and the real price per full cord. Not included: loose, thrown-in wood in a truck bed or crisscrossed stacks (stack it in tight, parallel rows first, then measure), wood moisture or heat value, delivery fees, and state rules beyond the NIST Handbook 130 method of sale (your state may add its own). The rule: under NIST Handbook 130, which most states adopt into law, a cord is the amount of wood in a space of 128 cubic feet when the wood is ranked and well stowed (pieces in a row, touching, parallel and stacked compactly), commonly 8 feet long × 4 feet high × 4 feet deep. Firewood may be sold only by the cord, a fraction of a cord or the cubic meter, and sellers may not use “face cord”, “rack”, “pile” or “truckload”. The math is the one in the NIST and state weights and measures guides: width × height × length; 128 cubic feet is one cord (4 × 4 × 8 ft or 2 × 4 × 16 ft). The depth is how far the stack goes from front to back, which is usually the length of one log. Everything stays in this browser tab; nothing is sent or saved.

How to use it (step by step)
- 1Stack the wood in tight, straight rows with the pieces parallel and touching. Then measure the stack’s length and height in feet (for 8 ft 6 in, type 8.5).
- 2Measure how deep the stack is from front to back in inches; for a single row this is the length of one log, often 16 inches. If you have several stacks of the same size, enter how many.
- 3Read how many cords you have. To check a delivery, add the price and the amount you paid for (for example 1 or 0.5 cord) to see if you were shorted and what you really paid per full cord.
Words to know
- Cord
- The legal unit for firewood: 128 cubic feet of wood stacked neatly, for example a pile 8 feet long, 4 feet high and 4 feet deep.
- Face cord
- A word some sellers use for a single row of logs. It has no legal size, so how much wood you get depends on the row’s length, height and log length. Measure it here.
- Ranked and well stowed
- Stacked in neat rows with the pieces lying side by side, touching and parallel, with few gaps. That is how a cord must be measured.
- Cubic foot
- A box 1 foot long, 1 foot wide and 1 foot high. A cord holds 128 of them.
