How to Choose the Right Bird Cage for Your Species
A bird cage is not a piece of furniture. For most pet birds it is the place where they eat, sleep, play, and spend a large share of every day for years, sometimes decades. The wrong one can cause injuries that no amount of affection can undo, which is why it pays to choose the right bird cage before your bird comes home rather than after a scare.
The trouble is that there is no single right answer. A finch that crosses its cage on the wing and a macaw that climbs, chews, and tests every weld are living in completely different worlds, and a cage that suits one can be unsafe for the other. Cage size, bar spacing, bar strength, and materials all depend on the species you keep.
This guide shows you how to match a cage to your bird. You will learn which measurements actually matter, why bar spacing is a safety issue and not a style choice, how cage materials differ, and what size and bar spacing to look for in each group of birds, from finches and budgies to African greys, Amazons, and macaws. We also point to specific A&E cages along the way so you can see what the numbers look like in real products.

Why Your Bird's Species Comes First
Birds use their homes in very different ways. Finches, canaries, and budgies move mostly by flying, so they need width to cross from one side to the other. Climbing parrots such as conures, Amazons, and cockatoos travel along the bars with their feet and beaks, so they need strong horizontal bars and enough height for perches at several levels. Long-tailed birds such as cockatiels and macaws need clearance so their tail feathers do not bend against the floor or the bars.
Two more species traits matter just as much. Head size decides how far apart the bars can safely be, and beak strength decides how tough the bars, welds, latches, and finish need to be. A budgie is not going to damage a well-made cage. A large macaw can bend thin wire, work a weak latch open, and chew through a poor finish. That is why a cage sold as a parrot cage is not automatically the right cage for your parrot, and why the first step is knowing your species and its full adult size.
How to Choose the Right Bird Cage: Three Measurements That Matter
Width and Depth Matter More Than Height
Shoppers tend to be drawn to tall cages, but birds do not use them that way. The bird-care team at Lafeber and the St. Louis Avian Rescue (STAR) both point in the same direction: horizontal space is far more useful than vertical space, because birds fly and flap sideways and rarely use the top of a very tall cage. STAR tells adopters to judge a cage by its width and depth, not its height, and to check the real measurements because advertised dimensions can include seed guards.
Height still has a job, because it lets you place perches at different levels and gives long-tailed birds room to clear the floor. But a very tall cage with a small footprint is a poor home for a bird that flies, so compare width and depth first and height second.
The Wingspan Rule of Thumb
A quick way to test any cage is to compare it with your bird's wingspan. PetSmart's guidance is that a cage should be at least twice as wide as the wingspan, while an avian veterinarian quoted by ZuPreem suggests a width of about 2.5 times the wingspan and a depth of about three times. The rules do not match, so treat them as a floor rather than a target. If your bird cannot fully extend both wings, turn around, and move between perches without touching anything, the cage is too small no matter what the label says.
Bar Spacing Is a Safety Measurement

Bar spacing is the gap between two neighboring bars, and it is the most important safety number on any cage. If the gap is too wide, a small bird can push its head through and get trapped, and a trapped bird can be badly hurt or killed. Keepers often report that a head slips through in one direction and then refuses to come back out. If the gap is too narrow for a large bird, toes and beaks can catch. Smaller birds need tighter spacing and larger birds need wider spacing, and the exact ranges by species appear below. Within your species range, choose the tighter option.
Bar strength matters too. Bar gauge, which is the thickness of the wire, needs to match your bird's beak. A&E's flight cages for small birds use 3 mm bars, while its larger parrot cages, such as the 36" x 28" dome top, step up to 5 mm bars. Check both numbers in the specifications for the exact model and color you are buying, because spacing and gauge can differ between cages that look almost identical.
Bird Cage Size and Bar Spacing by Species
The chart below brings together the minimum cage requirements published by St. Louis Avian Rescue, a nonprofit that sets cage standards for the parrots it places, and checks them against ranges from other avian sources. Read every number as a minimum. Bigger is better, as long as the bar spacing stays safe for your bird.

|
Species group |
Minimum cage (width x depth) |
Bar spacing |
Good to know |
|---|---|---|---|
|
Finches and canaries |
30" x 18" for 1 to 2 birds; 31" x 20" for 3 or more |
1/2" or less |
Flight is their main exercise, so width matters most |
|
Budgies, lovebirds, parrotlets, green cheek conures |
24" x 24" for one bird; 31" x 20" flight cage for two or more |
1/2" or less |
Active climbers that need room for toys and perches |
|
Cockatiels, Quakers, ringnecks, Senegals, medium conures |
24" x 24" for one bird; 31" x 20" flight cage for two or more |
Up to about 0.6"; 1/2" is common |
Long tails need height clearance |
|
Caiques, Pionus, larger conures, Alexandrine parakeets, Hahn's macaws |
32" x 21" minimum; 32" x 23" or 36" x 24" better |
1/2" to 3/4" |
Stockier and stronger, so harder on cages |
|

|
Macaws and large cockatoos |
46" x 36" minimum; 80" x 40" if space allows |
1" to 1.5" |
Construction and durability matter most |
Sizes are width by depth in inches. Source: minimum cage requirements from St. Louis Avian Rescue (staravian.org).
If your bird sits between two groups, such as a large conure or a small Amazon, choose the larger cage size and ask an avian veterinarian or our team to confirm the bar spacing.
Finches and Canaries
Finches and canaries barely climb. They live on the wing, hopping and flying from perch to perch, so width is the number that counts. STAR's minimum for one or two birds is 30 by 18 inches with bars no wider than half an inch, and groups of three or more need at least 31 by 20 inches. Those are floors, and a wider cage is always better for a bird that exercises by flying.
The A&E 32" x 18" Multi Level Flight Cage meets the small-group minimum with 1/2-inch bar spacing, ladders between levels, and six feeder stations. For a larger flock or extra flying room, the A&E 40" x 30" Extra Large Flight Cage is listed as suited to finches, canaries, parakeets, cockatiels, and small conures, and it adds a great deal more space to fly.
Budgies, Lovebirds, Parrotlets, and Green Cheek Conures
Small parrots are often sold as starter birds, and that leads owners to buy starter cages. Budgies, lovebirds, parrotlets, and green cheek conures are athletic, curious, and social. STAR's minimum is 24 by 24 inches for a single bird and a 31 by 20 inch flight cage for two or more, with bars no wider than half an inch. A half-inch gap is tight enough to keep even the smallest of these birds from slipping a head through.
The A&E 32" x 21" Elegant Flight Cage clears the two-bird minimum with 1/2-inch bar spacing, horizontal side bars for climbing, and four swing-out feeder doors, and it comes with its own removable mobile stand. If you keep two birds that need to live side by side but not together, the A&E 64" x 21" Double Flight Cage with Divider gives each bird its own half.
Cockatiels, Quakers, Ringnecks, and Medium Conures
This group includes cockatiels, Quaker parrots, Indian ringnecks, Senegals, and medium conures such as Sun and Jenday conures. They are stronger climbers than the smaller parrots, and cockatiels and conures also have long tails that need height clearance. STAR's minimum is the same 24 by 24 inches for one bird and 31 by 20 inches for two or more, with bar spacing up to about 0.6 inch, though half an inch is common and perfectly appropriate. Lafeber's bird-care team stresses that conures are very active and need room to explore, along with plenty of toys.
The same A&E 32" x 21" Elegant Flight Cage works well here, and A&E lists cockatiels and conures among the birds it suits. Because these birds have long tails, look for enough interior height that your bird can sit on a perch without its tail touching the floor.
Caiques, Pionus, and Larger Conures
Caiques, Pionus parrots, blue-crowned and golden conures, Alexandrine parakeets, and Hahn's macaws are stockier and stronger than the smaller parrots, and they are harder on cages. STAR's floor for this group is 32 by 21 inches, with 32 by 23 or 36 by 24 recommended where space allows, and bar spacing from 1/2 to 3/4 inch. The A&E 32" x 23" Dome Top Bird Cage falls in that window with 5/8-inch bar spacing, 3.5 mm bars, a large front door, and three separately opening feeder doors. Its sibling, the A&E 32" x 23" Play Top Bird Cage, adds a play area on top for supervised time outside the cage.
African Greys, Amazons, Eclectus, and Small to Medium Cockatoos
This is where cage size and construction step up sharply. Amazons, African greys, Cape parrots, Eclectus, small and medium cockatoos, and mini macaws are powerful, intelligent, and active. STAR sets 36 by 24 inches as the minimum, lists 40 by 30 and 36 by 28 inches among common recommendations, and specifies bars between 3/4 and 1 inch. More active or larger birds in this group may need a 40 by 30 inch cage or bigger.
The A&E 36" x 28" Dome Top Bird Cage has one-inch bar spacing and 5 mm bars. The A&E 40" x 30" Dome Top Bird Cage, which A&E lists for Amazons, African greys, and cockatoos, offers 62 inches of interior height and plenty of climbing room. A dome top suits these birds because it gives them a climbable ceiling and more places to hang toys and perches, which we cover in the style section below.
Macaws and Large Cockatoos
Macaws and large cockatoos such as Moluccans and Umbrellas are the largest companion parrots, and they need cages to match. STAR sets a minimum of 46 by 36 inches with bar spacing of 1 to 1.5 inches, and suggests an 80 by 40 inch cage if you have the room. It also tells owners to pay special attention to construction and durability, because the beaks and climbing of these birds put real stress on every weld and latch.
The A&E 48" x 36" Dome Top Bird Cage and the A&E 48" x 36" Play Top Bird Cage both clear the 46 by 36 inch minimum, and the Play Top has one-inch bar spacing. For more room, the A&E 80" x 40" Double Macaw Cage with Divider fits the larger-cage recommendation, and the A&E 64" x 32" Double Macaw Cage with Removable Divider is a middle option. Because these birds are so tough on a cage, many owners look closely at stainless steel, which we cover next.
Cage Materials: Stainless Steel, Powder-Coated Steel, and What to Avoid
Once the size and bar spacing are right, the next question is what the cage is made of. Birds explore with their beaks, and a bird that chews on its cage is swallowing a little of whatever the cage is made from, so material is a health decision as much as a durability one.
Stainless Steel

Stainless steel is widely considered the safest option. Avian Enrichment, a parrot welfare resource, calls it the safest, most durable, and easiest cage material to keep clean, and notes that it does not chip or rust. An avian care article in Pet Business makes the same point for large parrots, which can live for decades and have the strongest beaks. The tradeoff is cost, because stainless steel is the most expensive material. A&E's stainless models use 304-grade steel, and A&E says the steel can be pressure washed for a deep clean. You can see the full selection in our stainless steel bird cages collection, including the A&E Stainless Steel 40" x 30" Dome Top Bird Cage and the A&E Stainless Steel 80" x 40" Huge Double Macaw Cage.
Powder-Coated Steel
Powder-coated steel is the standard for most cages and is a sound choice when it is well made. An avian veterinarian writing at For The Birds DVM notes that properly manufactured powder-coated steel cages can provide decades of safe service. The caution is that a coating can chip, exposing the metal underneath. Inspect the cage regularly and replace it if the finish begins to flake. A&E states that its powder-coated cages use a non-toxic finish and welded bar construction.
Galvanized Wire and Antique Cages
Avoid galvanized wire. It is coated in zinc, and Pet Poison Helpline warns that birds that pick at galvanized cages can swallow small amounts of zinc that build up in the liver, kidneys, muscle, and pancreas over time. Signs of zinc toxicity include excess urine in the droppings, staggering, greenish diarrhea, weakness, weight loss, seizures, and sudden death. Some inexpensive cages are powder-coated over galvanized wire, and coatings on slick galvanized surfaces can peel and flake. Avian care guidance also warns against antique cages because old paint can contain lead. If a cage shows pitting, white burrs, or white rust, retire it.
Dome Top, Play Top, or Flight Cage? Choosing a Cage Style
Flight cages are wide, rectangular, and built for small birds that need room to fly. Dome top cages have an arched top that gives parrots more interior space to climb and makes it easier to place toys and perches. Play top cages have a flat, built-in play area on top with ladders and a perch, which gives your bird a place to spend supervised time outside the cage. Avian Enrichment points out that you can get the best of both worlds with a dome top cage and a separate, portable play gym that moves with you from room to room.

Rectangular cages are the standard for a good reason. Round cages are attractive, but they cut into usable living space and are not recommended. Horizontal bars help birds climb, and a combination of horizontal bars on the sides with vertical bars on the front and back, which is how A&E builds its parrot cages, gives your bird climbing footholds and more places to hang toys.
Features That Make Daily Life Easier and Safer
Some cage features are about convenience, and some are about keeping your bird inside. Start with the doors. Intelligent parrots learn to open simple latches, so a cage for a parrot needs bird-proof locks on the main door and the feeder doors, not just spring clips. A large front door makes it easier to bring your bird in and out, and feeder doors you can reach from outside let you refill food and water without putting your hands in the cage.
Cleaning features matter more than most first-time buyers expect. A slide-out tray and a removable grate keep your bird away from droppings and make daily cleanup quick, and on large parrot cages the grate should lock in place so an escape artist cannot push it out. A removable seed guard cuts down on mess, and casters let you roll a heavy cage away from the wall for cleaning. A&E builds these features into its cages, including bird-proof door locks, slide-out grills and trays, and easy-rolling casters.
When your cage arrives, inspect it before your bird moves in. Check that the welds are smooth, the powder coat is not flaking, the top is secured to the frame, the locks work, and your bird cannot slip out when the tray is removed. Several larger models require assembly, so plan on having a second person to help.
Housing More Than One Bird
Every extra bird raises the space you need, and it is not as simple as doubling the cage. STAR's minimums step up for two or more small birds, from 24 by 24 inches for a single bird to a 31 by 20 inch flight cage for two, and finches move from 30 by 18 inches to 31 by 20 inches once there are more than two. Birds sharing a cage also need plenty of perches so every bird has a place to relax, and multiple feeding stations help prevent fights at mealtime.
Not every pair belongs in the same space all the time. Cages with dividers, such as the A&E 64" x 21" Double Flight Cage with Divider and the A&E 64" x 32" Double Macaw Cage with Removable Divider, let birds live side by side and let you separate them whenever you need to.
Where to Put the Cage
A good cage in a bad location still fails your bird. ZuPreem's guidance is to balance safety and stimulation: keep the cage away from anywhere people smoke, avoid strongly scented candles and diffusers, and skip essential oils altogether because they can be toxic to birds. Many avian veterinarians also advise keeping birds out of the kitchen, since fumes from overheated nonstick cookware are dangerous to them. A spot in a room where the family gathers lets your bird stay part of the household without those hazards. Before you order, measure the floor space and the door swing.
A Simple Checklist Before You Buy
Use this list as a final check before you order a cage for any species.
-
Identify your bird's species group and its full adult size, and measure the wingspan if you are unsure.
-
Find the minimum width and depth for that group, and go larger if you can.
-
Confirm the bar spacing and bar gauge in the specifications for the exact model and color.
-
Choose stainless steel or intact powder-coated steel, and avoid galvanized wire and antique cages.
-
Look for bird-proof door locks, feeder doors you can reach from outside, and a locking grate on large parrot cages.
-
Choose a slide-out tray, removable grate, and casters that make cleaning realistic.
-
Measure the space where the cage will live, including door swing.

Frequently Asked Questions About Choosing a Bird Cage
What size bird cage does a cockatiel need?
St. Louis Avian Rescue sets the minimum for a single cockatiel at 24 by 24 inches, and at a 31 by 20 inch flight cage for two or more. Bar spacing should be no wider than about 0.6 inch, and half an inch is common. Some sources list smaller minimums, but a larger cage is always better, and because cockatiels have long tails, choose one with enough height that the tail does not touch the floor.
What bar spacing is safe for a conure?
It depends on the conure's size. Green cheek conures need bars no wider than half an inch. Medium conures such as Sun and Jenday conures can use spacing up to about 0.6 inch, and larger conures such as blue-crowned and golden conures do well with 1/2 to 3/4 inch. When you are not sure, choose the tighter option and confirm with an avian veterinarian.
Is a bigger bird cage always better?
Bigger is better as long as the bar spacing is safe for your bird. A large cage with bars that are too wide is more dangerous than a smaller cage with the right spacing. Look at width and depth rather than height, because birds use horizontal space far more than vertical space.
Can out-of-cage time make up for a smaller cage?
No. Rescue organizations such as STAR are clear that time outside the cage does not replace an appropriately sized cage, because your bird still needs room for movement, toys, perches, and enrichment during the hours it spends inside.
Are stainless steel bird cages worth it?
For owners of large parrots, usually yes. Stainless steel is considered the safest, most durable, and easiest-to-clean material, and it does not chip or rust. It costs more up front than powder-coated steel, so it makes the most sense for macaws, cockatoos, and other hard chewers that will live in their cages for decades. A well-made powder-coated cage remains a safe choice for smaller birds while the finish is intact.
Are powder-coated bird cages safe?
Yes, when the cage is well made and the finish is intact. Powder-coated steel is the standard for most bird cages, and it is very hard for a parrot to strip the coating. Inspect the cage regularly, and retire it if you see chipping, flaking, rust, or pitting, especially on the grate.
Should I choose a dome top or a play top cage?
Choose a dome top if you want more interior climbing space and easier toy placement. Choose a play top if you want a built-in spot for supervised time outside the cage. Neither is better in every case, and some owners choose a dome top and add a portable play gym.
