Adult carpenter ants can measure from 6 to 12 mm in length. Males, or winged swarmers, can measure up to 18 mm, while queens grow to 20 mm in length.Carpenter Ant Size.A mature colony usually contains around 3,000 adult ants, but some species have been known to contain up to 100,000 ants. Like other ant species, carpenter ants are social insects, and their colonies are composed of different castes.ales, or winged swarmers, can measure up to 18 mm, while queens grow to 20 mm in length.
