Pick your Bird Size Category, Number of Birds, and Housing Type, and the Bird Cage Size Calculator tells you the Minimum Floor Area, Min Width/Length/Height, and Recommended Bar Spacing. Plug in your Current Cage dimensions to check if it meets the requirements.

Measure your bird from the tip of their head to the end of their tail while they're in a natural standing position. This gives you the total body length needed to select the correct size category.
Minimum sizes are the absolute smallest dimensions for bird welfare, assuming several hours of daily flight time outside the cage. Recommended sizes provide more comfort and are better for birds with limited out-of-cage time.
Bar spacing is critical for safety. Too wide and your bird can get their head stuck or escape; too narrow reduces visibility and climbing ability. Each bird size has specific spacing requirements.
Generally, birds of similar sizes can be housed together, but always research species compatibility. Use the largest bird's size requirements when calculating cage dimensions for mixed groups.
Yes, absolutely. Birds that spend most of their time in the cage need significantly larger spaces. The calculator adjusts requirements based on whether birds get daily flight time outside their cage.
While floor space is most important for exercise, adequate height allows for natural perching behavior and multiple perch levels. Height should be proportional to width and length.
Flight cages are longer horizontally, allowing for more natural flight behavior. They're ideal for active species or when out-of-cage time is limited. Regular cages work well with ample daily exercise time.
If your cage doesn't meet minimum requirements, consider upgrading as soon as possible. In the meantime, increase out-of-cage flight time and ensure your bird gets maximum exercise and mental stimulation.
