Firewood Cord Calculator

Estimate cords of firewood from any stack size.

How the firewood cord calculator works

A full cord is 4 ft × 4 ft × 8 ft = 128 ft³ of stacked wood. A face cord is 4 ft × 8 ft × log length (typically 16 in ≈ 1.33 ft).

Frequently asked questions

How much is a face cord vs a full cord?

A face cord with 16 in logs is 1/3 of a full cord (~42.7 ft³ vs 128 ft³).

How long does a cord of wood last?

For a woodstove used as primary heat, expect to burn 3–5 full cords per winter in cold climates.
