Cage size is where most new owners under budget, and it is the decision that affects your birds every hour of every day for the next decade. Worth getting right the first time.
A budgie needs a cage that is wider than it is tall, with bar spacing no more than 12mm, at least two perches of different thicknesses, food and water that cannot be soiled from a perch above, and room to fly a short distance rather than just hop. For two budgies, 60cm wide is the practical minimum. Bigger is always better.
Does a budgie need a cage?
Yes, even a bird that spends most of the day out of it. The cage is where a budgie sleeps, eats and retreats to when it wants to be left alone.
A budgie loose in a house without a base of its own is a bird at risk. Ceiling fans, open windows, cooking, cats, doors and people who do not know to look before they sit down all account for birds every year. The cage is not a prison, it is the one place in the house that belongs to the bird and is safe when you are not watching.

What cage is best for a budgie?
A wide, rectangular cage with horizontal bars. Not a tall narrow one, and never a round one.
Budgies fly horizontally. They do not hover and they do not climb the way a larger parrot does, so height beyond a certain point is wasted space. A cage 60cm wide and 40cm tall gives a budgie far more usable room than one 40cm wide and 60cm tall, even though the volume is much the same.
Horizontal bars matter too, because budgies climb sideways across them for exercise. A cage with only vertical bars gives them nothing to grip.
Avoid round cages. There are no corners to retreat into, which some birds find genuinely unsettling, and the curved bars make it harder to attach perches and toys properly.

What size cage do I need for 2, 3 or 4 budgies?
Sixty centimetres wide is the practical minimum for two budgies, 90cm or more for three or four, and a large flight or aviary for five or more. Use these as a working guide:
- Two budgies: 60cm wide minimum. This is what comes with our starter package and it suits a pair that gets time out of the cage.
- Three to four budgies: a flight cage of 90cm or more in width. Four birds in a 60cm cage will squabble, because there is not enough perching space to get away from each other.
- Five or more: a large flight, a Palace style cage, or an aviary. At this point you are running a small flock and they need room to move properly.
If your birds are out of the cage for a good part of the day, the lower end of those cage sizes is fine. If they are in the cage most of the time, go bigger than the minimum. The cage is their world.
What bar spacing does a budgie cage need?
No more than 12mm between bars, and 10mm is safer.
This is a genuine safety issue, not a preference. Budgies push their heads through gaps, and a bird can get its head stuck in spacing designed for a larger parrot. Cages sold as generic bird cages are often spaced for cockatiels or bigger, so check the measurement before you buy rather than trusting the label.
What do you put on the floor of a budgie cage?
Plain paper. Newspaper or purpose made cage liner paper both work perfectly well.
Paper is best because it lets you see the droppings, and droppings are the earliest warning you get that something is wrong. Colour and consistency change before a bird looks sick. If the floor is covered in sand or shavings you cannot see any of it.
Do not use sandpaper sheets. They were sold for years on the theory that they keep nails trim. They do not, and they can irritate a bird's feet. Cat litter, sand and wood shavings are worse again, because birds pick at them and some grow mould once they get damp.
How often should I clean a budgie cage?
Paper every day, food and water bowls washed every day, perches and toys weekly, and a full clean once a month.
Changing the paper takes twenty seconds and gives you a look at the droppings while you do it. Bowls need washing rather than topping up, because a film builds up on the inside that you will not see. Once a month, take everything out, scrub the tray, the bars and the perches, let it all dry properly and put it back.
Use hot water and a bird safe cleaner or plain white vinegar. Never use bleach, disinfectant sprays, oven cleaner or anything aerosol near birds. Their respiratory systems are far more sensitive than ours and fumes that mean nothing to you can kill them.
What do budgies need in their cage?
The essentials, in order of importance:
- Perches of varying thickness. Natural wood branches are best, because the irregular shape works the foot muscles and prevents pressure sores. The plain dowel perches that come with most cages are all one diameter, so add a couple of natural ones.
- Food and water positioned away from perches. Anything directly under a perch gets soiled. It sounds obvious, but most cages come set up badly.
- A cuttlebone or mineral block. Permanent fixture, for calcium and beak condition.
- Two or three toys, rotated. Chewable wood, a swing, a ladder, something to forage in. Not so many that the bird cannot fly across the cage.
- A bath, offered a few times a week. Most budgies love bathing and it keeps the feathers in good order. A shallow dish or a clip on bath both work.
What they do not need is a mirror, at least not if the bird lives alone. A single budgie will bond to its own reflection, feed it, court it and then become distressed when it does not respond. If you want your bird to have company, get it a real one.
Is it cruel to leave a budgie in a cage?
Not in itself, provided the cage is the right size and the bird gets time out of it every day.
A cage is a safe place to sleep, eat and retreat to. What is unfair is a bird that never comes out of one. Budgies need to fly properly and no domestic cage is big enough for real flight. Aim for at least an hour a day out, in a closed room with the windows shut and the fans off.
If a bird cannot be let out safely yet, or you are not confident handling it, the answer is a bigger cage and a playground on top of it, not a smaller world. Our playgrounds sit on a stand or a cage top and give the birds somewhere else to be.
Where should the cage go?
Against a wall rather than in the middle of a room, somewhere the family actually spends time, out of direct sun and away from draughts.
A cage against a wall gives the birds one side they do not have to watch, which settles them. Budgies also want to be part of the household, so a spare room nobody enters is worse for them than a busy lounge room.
Never in the kitchen. Overheated non stick cookware releases fumes that kill birds very quickly and there is no warning at all. This is the most common avoidable death we hear about on the helpline.
Cover the cage at night if the room stays lit. Budgies need ten to twelve hours of dark to sleep properly, and a tired bird gets sick.
_____________
Wide beats tall. Bar spacing 12mm or less. Plain paper on the floor, changed daily. Natural wood perches of different thicknesses. Food and water clear of the perches. A few toys, rotated. Out of the cage every day, and never anywhere near the kitchen.
Buy the biggest cage you have room for and can afford. Nobody has ever regretted it, and most people upgrade within a year anyway.
Free health checks, free wing trims, free dietary advice. That is what we do at Just Budgies, and it does not stop the day you take your birds home.
