Keeping birds can be done well, and to the benefit of both them and us. But too often in doing so we take away the very thing that defines them: flight. So here are some suggested minimum case sizes to allow your feathered friends to enjoy their fullest lives.
Why is it important? Studies have repeatedly shown that birds in smaller cages are more likely to suffer from:

Dimensions display minimum floor areas; long rectangles work better than squares for these types of spaces. All measurements are in cm.
Length of bird | 1 bird | 2 birds | 4 birds | Height |
10 (finch, canary) | 100 x 37 | 100 x 55 | 150 x 61 | 60 |
20 (budgie, bourke) | 160 x 45 | 180 x 60 | 200 x 90 | 60 |
30 (cockatiel) | 180 x 60 | 200 x 75 | 200 x 150 | 90 |
40 (most parrots) | 200 x 75 | 225 x 100 | 250 x 150 | 90 |
50 (most cockatoos) | 250 x 100 | 250 x 150 | 250 x 250 | 150 |
*An outdoor aviary or cage’s minimum dimension in any direction shouldn’t be less than 60 cm. **Any outdoor aviary or cage should have a minimum height of one 5 meters above the ground to give birds a safe haven from predators The Queensland code of practice stipulates a 180cm height outdoors.
Some Notes On Cage Sizes
The Victorian Code of Practice for the Housing of Caged Birds and the Queensland Aviculture Code of Practice 2010 are the two sources of information that I used. Due to their social nature, most birds should be kept in groups of two or four rather than alone. Therefore, sizes for multiples have also been included.
For each, I have used recommended sizes for outdoor cages. These are ideal for smaller birds like cockatiels and budgerigars indoors. I hope you can go over these measurements whenever you can, or give your bird daily freedom to fly around the house.
Cages outside require roofs and a single, sturdy wall that faces the direction of the wind. Additionally, all cages require a range of sized natural stick perches that are positioned so they don’t obstruct flight.
My tiel is 23″ long, 14″ wide, and 16″ tall, and I would really like to get her a larger cage. The one she came with when I rescued her seems too small. Google states that the dimensions are 24″ long, 18″ wide, and 24″ tall, but I wanted to check with you guys to see what you thought. In addition, is 5/8 bar spacing too much? I really don’t want to have to spend a lot of money, but I’ll do whatever it takes to make sure she’s satisfied.
