Select your bird species from the dropdown and the calculator instantly displays the minimum recommended cage dimensions plus the correct bar spacing to keep your bird safe.
- Select your species. Choose from budgies, cockatiels, conures, African greys, macaws, canaries, lovebirds, cockatoos, and Amazon parrots.
- Read the minimum dimensions. Dimensions are shown as Width x Depth x Height in inches. These are the absolute minimums; a larger cage is always better for your bird's welfare.
- Check bar spacing. Bar spacing is critical for safety. Bars too wide let small birds escape or get their head stuck. Bars too narrow stress larger birds.
- Use the notes. Each species entry includes a care tip about cage orientation, latch security, or material preferences specific to that bird.

About Bird Cage Size Recommendations
Cage size recommendations are based on guidelines from avian veterinary associations and bird welfare organizations. The minimums shown represent the smallest acceptable space for a bird that also gets regular out-of-cage time. A bird kept in its cage most of the day should have a cage significantly larger than the minimum. For flight cages, width is most important since birds fly horizontally. For climbing species like parrots, height matters more.
Bar spacing is just as important as overall size. Bars spaced too widely allow small birds like budgies to push their heads through and get stuck, which can cause injury or death. For large parrots, bars must be heavy gauge to resist bending under strong beaks. Stainless steel and powder-coated cages are the safest material choices. Avoid cages with zinc or lead-based finishes, which are toxic when chewed.
Frequently Asked Questions
What is the minimum cage size for a budgie?
The minimum recommended cage size for a single budgie is 18 inches wide by 18 inches deep by 18 inches tall, with bar spacing of 1/2 inch. Since budgies fly horizontally, a wider cage is more beneficial than a taller one. For two budgies, double the width at a minimum. Budgies should have out-of-cage flight time daily if the cage is at the minimum size.
What bar spacing does a cockatiel need?
Cockatiels need bar spacing of 5/8 inch. Spacing larger than this risks the bird pushing its head through and becoming trapped. Smaller spacing is safe but makes the cage heavier and harder to clean. Cockatiels are climbers, so at least two sides of the cage should have horizontal bars to allow them to grip and move around the cage interior easily.
How big does a macaw cage need to be?
The minimum cage for a macaw is 36 inches wide by 48 inches deep by 60 inches tall, with bar spacing of 1 to 1.5 inches. Macaws have a wingspan that can exceed 3 feet, and their cage should allow them to fully extend their wings without touching the sides. Many experienced macaw owners use custom-built or extra-large commercial cages well beyond these minimums, supplemented with substantial daily out-of-cage time.
Are round bird cages okay to use?
Round cages are generally not recommended by avian veterinarians. Birds feel more secure when they can retreat to a corner, and round cages provide no corners. The converging bars at the top of round cages can trap toes and cause injury. Round cages also provide less usable interior space than a square cage of similar diameter. For most species, a rectangular cage is the safer and more comfortable choice.
