What Size Cage Does Your Bird Need?
Calculate minimum cage dimensions by bird species. Bar spacing, shape, and placement recommendations.
Cage Sizing Philosophy
The cage should be large enough for the bird to fully extend its wings without touching the sides and take short flights between perches. Width is more important than height — birds fly horizontally, not vertically. The minimum cage sizes listed are truly minimums for species that get significant daily out-of-cage time. If your bird spends most of the day caged, double the minimum dimensions.
Bar Spacing Is Critical
Bar spacing must match the bird's head size — too wide and the bird can get its head stuck (potentially fatal). Too narrow and the bird cannot climb comfortably. Small birds (budgies, finches): 3/8-1/2". Medium birds (cockatiels, conures): 1/2-3/4". Large birds (African Greys, cockatoos): 3/4-1.5". Always check bar spacing before purchasing.
The biggest cage you can afford and fit in your home is almost always the right choice. Birds in larger cages exhibit less stress behavior (feather plucking, screaming, aggression) and are generally healthier and more interactive with their owners.
