Seasoned weight per full cord, highest official figure for each wood. Woods with only one, likely low, source are left off. Figures in lb per cord, seasoned.

Weight of your wood

The sums behind this tool are tested against 5 worked examples printed in published sources, and 17 checks in all, including the limits where it gives no number.

Cord weight by species

These figures come from university extension and state forestry tables. Where they disagree, we use the highest weight, so estimates lean heavy.

Green vs seasoned firewood weight

Green wood is freshly cut. Seasoned wood has dried in the air, and Utah State University's table defines its dry weight as "the weight of a cord after air drying."

The gap can be large. Green cottonwood is listed at 4,640 pounds a cord, against 2,272 pounds seasoned.

The tables don't all state the same moisture for seasoned wood, which is one reason we take the highest figure. Wood that isn't fully dry weighs more.

Can my truck carry a cord of wood?

We can't tell you that: it depends on your vehicle. Find the payload on the sticker in the driver's door jamb or in the owner's manual, and compare it with the weight above.

A half cord weighs half as much as a full cord of the same wood.

For the space side of the question, measure your bed and use the stack calculator.

Why some woods show no figure

Several woods have no official green weight in the tables we use, including hickory, sugar maple, American beech, hemlock, eastern white pine, quaking aspen and eastern redcedar. The calculator gives no number for those rather than guess.

Yellow-poplar and sweetgum have only one cord weight each, from a table that runs low against the others. We leave them out of the weight calculator until a second source confirms them.

Questions people ask

How much does a cord of oak weigh?

Seasoned red oak is listed at about 3,757 pounds a cord and seasoned white oak at about 4,200 pounds. Green oak weighs more.
