How to use the Parrot Cage Size Selector
A cage is where a bird spends its day, so whether it can turn and fly across the inside matters more than the numbers on the product listing. Measure the wingspan in inches, choose the multiple to apply to width, depth and height, and this selector works out the cage dimensions to look for along with the floor area. The table below applies every multiple that is in circulation, so you can see where a given product sits.
The key point is that the multiple has never been settled. Some sources treat 1.5 times the wingspan as the minimum, others recommend 2 times, and others again recommend 3 to 4 times to allow for actual flight. Since none of these can be declared the minimum, this tool lets you choose, and starts with the same multiple pre-selected for all three dimensions. If the source you follow gives different multiples per dimension, change each box to match it.
As of October 2026, no veterinary body such as AAHA or WSAVA publishes a minimum cage specification by bird species. Parrots alone run into hundreds of species with very different activity needs, so this tool asks you to pick none. It also calculates cage dimensions only: bar spacing and out-of-cage time are outside its scope. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
Frequently asked questions
Recommendations of 1.5, 2 and 3 to 4 times the wingspan all circulate, so the tool names no single right answer. Choose the multiple your species care source gives, and where it gives a range, look at the larger end first.
Because no recognized standard splits the multiple by dimension. Inventing a split would make it read like a rule, so all three boxes start equal and you can change each one to match your source.
No. Bar spacing is directly tied to the risk of a bird trapping its head, and it depends on species and body size, so check the product specification and ask your veterinarian or breeder.
