The black woodpecker measures 45 to 55 cm (18 to 22 in) long with a 64 to 84 cm (25 to 33 in) wingspan. Body weight is approximately 250 to 400 g (8.8 to 14.1 oz) on average.

The closely related pileated and white-bellied woodpeckers also broadly overlap in size with the black woodpecker, but both are somewhat smaller in average and maximal size and mass.
