Large Parrot Cages UK: Extra-Large, Double & Triple Cages Compared
Short answer: a “large” parrot cage is one with roughly 90–100 cm or more of internal width, 2–2.5 cm bar spacing and heavy wire (4–6 mm). That’s the size range for African Greys and Amazons at the smaller end, and for macaws and big cockatoos at the top end. If you want room for two birds, look at a cage with a removable divider or a stacked double or triple cage. If you have the floor space, an indoor aviary is the next step up.

How big is “large”? Sizes by species
There’s no official definition, so we go by the bird. Measure your parrot from head to tail tip and think about its wingspan. It should be able to open both wings fully inside the cage and turn on a perch without its tail touching the bars or the floor grille.
- African Greys, Amazons and Eclectus: aim for at least 80–90 cm of internal width. The Toronto II, Parrot Double and Rio Ara all give more than that. See our African Grey cage size guide.
- Large cockatoos (umbrella, Moluccan, sulphur-crested): 100 cm or more of width, with 2.5 cm bars and 5 mm wire. See our cockatoo cages guide.
- Macaws: 100–120 cm wide as a starting point, and wider if you can. Read what size cage a macaw needs and our best macaw cages shortlist.
Always compare the internal measurements where we list them. Seed catchers add width outside the cage but no living space inside it.
Single, double or triple: which type do you need?
One big bird: a single large cage
For one macaw, cockatoo or Grey, a single open cage gives the most usable space for the money. The Rio Ara is our all-rounder for big birds, with 2.5 cm bars, 5 mm wire, a 100 cm perch and four 15 cm bowls. The Parrot Double is a similar size and comes with two 102 cm perches.
Two birds: a dividable cage
If you keep a pair, or need to separate birds during introductions, choose a cage with a removable divider. The Castello II is about 162 cm wide and has a divider, seed catchers, pull-out trays and castors. The Nova 2 splits into two 102 × 100 × 200 cm sections, or opens into one 205 cm space.
Several birds kept apart: stacked triple cages
Triple cages stack three separate compartments on one frame. Each section is lower than a single cage, so they suit birds that need their own space, such as during quarantine, or a household with several smaller parrots. They aren’t a full-time home for one large bird. The Grande Triple has 6 mm wire and 2 cm bars. The Parrot Triple has 1.5 cm bars, which suit smaller parrots such as Senegals.
When to step up to an aviary
If your bird spends long hours in its cage, or you want two large parrots together, an indoor aviary gives far more room to climb and flap. The Nova 2 is the most compact of our large-parrot aviaries. For the full range, read our indoor aviaries guide. Even the biggest cage is a base. Your parrot still needs daily supervised time out, and a play stand gives it somewhere to go.
Fitting a big cage into a UK home
- Measure the route in. Check doorways, hall corners and stair turns as well as the room. Large cages usually arrive on a pallet, flat-packed or part-built.
- Allow for seed catchers. They add about 20 cm to the width and depth of cages like the Rio Ara and Toronto II.
- Corners save space. The Toronto II uses a corner footprint, so it takes up less of the middle of the room. Our corner cages guide has more detail.
- Check the floor. Castors only help on a level, hard floor. Put a mat underneath to protect carpet.
- Delivery. Allow 5–7 working days. If access is tight, contact us before you order and we’ll help you check.
Large parrot cage FAQs
What is the biggest parrot cage you sell?
Of our cages, the Castello II is the widest at about 162 cm. The Nova 2 is bigger again at 206 × 101 × 220 cm, and our full aviaries go up to 219 × 158 × 210 cm. See the aviaries guide.
What bar spacing does a large parrot cage need?
Usually 2–2.5 cm for large parrots, with 4–6 mm wire. Your bird should never be able to fit its head between the bars. Our bar spacing guide covers this by species.
Can two parrots share one large cage?
Only if they get on well and the cage is big enough for both to perch, eat and move apart. A dividable cage such as the Castello II or Nova 2 lets you house them side by side first.
Do large parrot cages come assembled?
Most arrive flat-packed or part-assembled. Plan for two people to build and move one.
