How big should a bird cage or aviary be?
Minimum floor area, suggested cage size, perch length and seed kg per month from bird species and count.
Quick answer
Pet birds need **width to fly**, not just height for a swing. Hobby targets scale by species: a pair of **budgies** wants a long flight cage more than a tall tower; **cockatiels** need still more floor. Perches should offer varied diameters — roughly **15–25 cm** of usable perch length per bird is a starting point, plus toys that do not block flight paths.

Hobby targets prioritize flight width over tall towers. Floor ≈ birds × cm²/species; suggested size scales the base cage with √birds on length/width. Perch ≈ birds × cm/species. Seed is a mixed-seed ballpark — add fresh veg and weigh leftovers. Not veterinary advice; larger flight cages are kinder.
How it works
Enter species and bird count for a practical minimum floor area, a suggested L×W×H, perch length and seed kg/month. Tiny “starter” cages often fail the flight test. Not veterinary advice — larger is kinder whenever you can.
Frequently asked questions
Budgie cage size for two birds?+
Aim for a long cage — often cited around 80–100 cm width for a pair — so they can hop and short-fly. Height alone does not replace a flight path.
Cage or outdoor aviary?+
An outdoor aviary gives more flight if predator-proof, shaded and draft-safe. Indoor flight cages still need daily out-of-cage time for many species.
How much seed do birds eat?+
Rough ballparks: budgie ~5–10 g/day, canary a bit less, cockatiel ~10–20 g/day — plus fresh veg. The tool scales by count; weigh leftovers and adjust.
Can different species share a cage?+
Often no — aggression and diet differ. When in doubt, separate housing. Ask an avian vet before mixing.
