Why Bird Cage Size Matters
Choosing the right bird cage size is one of the most important decisions you'll make as a bird owner. A cage that's too small can cause stress, feather plucking, and health problems, while the right size gives your bird room to stretch, climb, and thrive.
At YES4PETS, we stock a wide range of bird cages and aviaries to suit every species — from small budgies to large parrots. Here's everything you need to know before you buy.
General Rule: Bigger Is Always Better
As a starting point, your bird should be able to fully extend both wings without touching the sides of the cage. They should also be able to move between at least two or three perches comfortably. If in doubt, always size up.
Cage Size by Bird Species
Small Birds (Budgies, Canaries, Finches)
Minimum cage size: 45cm W × 45cm D × 60cm H. These birds are active flyers, so a longer cage (wider than it is tall) is ideal to allow horizontal flight.
Medium Birds (Cockatiels, Conures, Lovebirds)
Minimum cage size: 60cm W × 60cm D × 90cm H. Cockatiels in particular love to climb, so vertical height is important.
Large Birds (African Greys, Amazons, Eclectus)
Minimum cage size: 90cm W × 60cm D × 120cm H. These intelligent birds need space for enrichment toys and multiple perches.
Extra-Large Birds (Macaws, Cockatoos, Large Parrots)
Minimum cage size: 120cm W × 90cm D × 150cm H or larger. For these birds, a full aviary setup is often the best option.
Bar Spacing: Don't Overlook This
Bar spacing is just as important as overall cage size. If bars are too wide, small birds can escape or get their heads stuck. If too narrow, larger birds can't grip properly.
- Small birds (budgies, finches): 1–1.5cm bar spacing
- Medium birds (cockatiels, conures): 1.5–2cm bar spacing
- Large birds (parrots, cockatoos): 2–3cm bar spacing
Indoor Cage vs. Outdoor Aviary
If you have multiple birds or a large parrot, an outdoor aviary may be a better long-term solution. Aviaries allow birds to experience natural light, fresh air, and much more space to fly freely.
Our Bird Cages collection includes everything from compact indoor cages to full-size aviaries with castor wheels for easy repositioning.

Other Things to Consider
- Cage shape: Rectangular cages are best — round cages can disorient birds and reduce usable space.
- Placement: Position the cage at eye level, away from drafts, direct sunlight, and kitchen fumes.
- Accessories: Leave room inside for perches, food/water bowls, and enrichment toys without overcrowding.
