What size bird cage do I need? The short answer: the biggest cage that fits your space, with bar spacing that is safe for your bird. A cage that is too small limits flapping and climbing, while bars that are too wide can trap a small bird's head. This bird cage size chart lists minimum cage sizes and bar spacing for common pet birds, plus the cages we would choose for each.
Why cage size matters more in winter
Pet birds spend more time indoors and inside their cage during cold, dark months. A roomier cage with several perches gives them space to stretch their wings and stay active until longer days return.
Bird cage size chart
| Bird | Minimum cage (W x D x H) | Bar spacing |
|---|---|---|
| Finches, canaries | 18" x 18" x 18" (wider is better) | 1/4"-1/2" |
| Parakeets (budgies) | 18" x 18" x 24" | 1/2" |
| Cockatiels, lovebirds | 20" x 20" x 28" | 1/2"-5/8" |
| Conures | 24" x 24" x 30" | 5/8"-3/4" |
These are minimums for one bird. Add width for each extra bird; small birds fly side to side, so width matters more than height for finches and canaries. Always check the bar spacing on the product page against your bird's size.
Cage features to look for
- Horizontal bars for climbing birds like parakeets and cockatiels.
- A slide-out tray for daily cleaning.
- Multiple doors for easy access to food and your bird.
- An open top or play top for out-of-cage time.
- Casters to move the cage away from drafty windows in winter.
