Free firewood cord calculator for stacking and ordering. Measure a rectangular wood pile in feet or enter full cords—we convert to cubic feet, cord equivalents, and common face-cord volume using 128 ft³ per cord and 42.67 ft³ per face-cord slice in the one-third definition.

A full cord is a volume measure for stacked firewood: 128 cubic feet of the stack’s outer boundary. We compute that volume from length × width × height in feet, then express it as full cords (divide by 128) and as equivalent face cords using one common third-of-a-cord definition (~42.67 ft³ per face cord).
ft³ = length × width × heightfull cords = ft³ ÷ 128face cords ≈ ft³ ÷ (128 ÷ 3)ft³ from cords = cords × 128More yard volume? Try fill dirt and crushed stone.
