Bird Cage Size Calculator
Calculate the minimum cage size for your bird species.
Ensure proper space for health and happiness.
Recommended Cage Size
Bird cage sizing is based on species size and wingspan. Birds need room to spread their wings and fly short distances.
Minimum cage width rule: The cage should be at least 1.5× the bird’s wingspan in width. Length should be at least 2× the wingspan for flight space.
Recommended minimums by bird size:
- Small (finches, canaries): 18" × 18" × 24" (46 × 46 × 61 cm)
- Medium (budgies, cockatiels): 24" × 18" × 24" (61 × 46 × 61 cm)
- Large (conures, Amazons): 36" × 24" × 48" (91 × 61 × 122 cm)
- Extra Large (macaws, cockatoos): 48" × 36" × 60" (122 × 91 × 152 cm)
Bar spacing matters too:
- Small birds: 3/8" – 1/2" (1–1.3 cm)
- Medium birds: 1/2" – 3/4" (1.3–2 cm)
- Large birds: 3/4" – 1" (2–2.5 cm)
Multiple birds: Add 50% more space per additional bird. Bigger is always better — these are minimums.
