Cages for Pet Birds
Guidelines for Cage Size and Bar Spacing

As discussed in "Before You Buy a Bird Cage," the following are minimum guidelines only. In all cases, the larger the cage you can get, the better. Remember, your bird will spend a good deal of time in his or her cage so it needs to be as spacious as possible.

Even though some birds are quite small, most are active and need the exercise afforded by a large cage to be healthy and happy. Also remember that birds with long tails need taller cages than their shorter-tailed counterparts, to make sure they can manouver around the cage and not damage their tails.

Bar spacing is also important because inappropriate bar spacing can result in injury to your bird. Here are general guidelines for cage size and bar spacing for some common pet birds:

Note: all dimensions are given in inches and in the format width x length x height.

Species Minimum Cage
Bar Spacing
Finches 18"x30"x18" 1/4" to 1/2"
Canaries 18"x24" x18" 1/4" to 1/2"
Budgies 18"x18"x24" 1/2"
Cockatiels 20"x20"x24" 1/2" to 5/8"
24"x24"x24 1/2"
Ringneck Parakeets 24"x24"x36" 1/2" to 5/8"
24"x24"x24" 5/8" to 3/4"
24"x24"x36" 5/8" to 3/4"
Mini Macaws
Goffin's Cockatoos
African Greys
24"x36"x48" 3/4" to 1"
Large Cockatoos 36"x48"x48" 1" to 1.5"
Large Macaws 36"x48"x60" 1" to 1.5"
Doves and Pigeons *see below 1/2" to 5/8"

*Dove and Pigeons: Doves need daily flight time so should either be kept in a flight cage or given daily flight time outside of the cage. With time outside of the cage for exercise, diamond doves can be kept in a cage 24"x24"x24" with bar spacing of no more than 1/2" and ringneck doves in a slightly larger cage (for example, 24"x36"x24"). Pigeons are most often kept in outdoor flights but if kept indoors need a large cage and daily flight time as well.

Metric Conversion: to convert to centimeters, simply multiply the stated dimensions by 2.54. It may helpful to remember that 12 inches is 30 cm, so a cage that is 24"x24"x36" is 60cmx60cmx90cm.
