Bird Cage Size Calculator
Find the minimum cage dimensions for your bird species. Covers budgies to macaws.
Quick Answer
Minimum cage size varies widely: budgies need 18x18x18", cockatiels 24x18x24", African Greys 36x24x48", and large macaws 48x36x60". Width is more important than height for most species. Add 50% space per additional bird.

About This Tool
The Bird Cage Size Calculator helps you choose the right cage for your feathered friend. It covers species from small finches to large macaws, with minimum dimensions, bar spacing, and multi-bird adjustments.
Minimum vs. Ideal
The sizes shown are minimums. Bigger cages reduce stress, prevent feather plucking, and allow natural behaviors like climbing and short flights. If your bird spends most of the day in the cage (while you're at work), aim for at least 1.5-2x the minimum dimensions.
Cage Shape Matters
Rectangular cages are best. Round cages don't provide corners where birds feel secure, and the converging bars at the top can trap toes and wings. Wide, rectangular cages with horizontal bars on at least two sides give the best combination of flight space and climbing opportunity.
