An adult Alexandrine parakeet needs a cage of at least about 36 inches wide, 24 inches deep and 36 inches tall, and that figure is a floor, not a target. The Alexandrine is one of the largest parakeets, a big-shouldered Asiatic parrot whose long, tapered tail alone accounts for much of its total length. A cage that fits a ringneck comfortably will cramp an Alexandrine, fraying that tail, restricting wing stretching and souring the bird's temper. If you have room for a cage closer to 40 inches wide with more height above it, this active, chewing species will use every inch, and daily out-of-cage time remains essential regardless of cage size.
Measuring for Wings and Tail, Not Just Body
Measure an Alexandrine's cage by what the bird does inside it, not by its body length on a chart. Fully extended, its wings need clear space to open and flap in place without striking bars, toys or dishes, because that flapping is basic exercise and a release for frustration in a caged parrot. Turning matters as much: an Alexandrine pivoting on a perch sweeps that long tail through a wide arc, and a cage too shallow front to back forces the tail against bars, breaking and bending feathers and coating them in whatever is on the cage floor. Depth is the dimension buyers most often skimp on, and it is the one this species notices first.
Bar Spacing and Strength for a Powerful Beak
Bar spacing and build quality are part of size, because an Alexandrine parakeet has a notably large, powerful beak for a parakeet. Spacing around three quarters of an inch to one inch lets the bird climb and grip without any risk of pushing its head between bars and becoming trapped. Bars must be stout and the welds and door catches strong, since this species tests every fixture methodically and can flex thin wire, pop weak welds and learn simple latches.
Fitting Perches, Dishes and Toys Into the Minimum
A minimum cage only works if the Alexandrine's furniture respects the space. Set the main perch high enough that the tail hangs clear of dishes and the floor when the bird sits upright, and leave a genuinely empty flight lane across the cage where wings can open without threading between toys. Alexandrines are enthusiastic chewers, so offer substantial natural wood perches and rotate chunky toys in one corner rather than filling the centre.
Why Out-of-Cage Time Does Not Shrink the Minimum
Daily out-of-cage time improves an Alexandrine parakeet's life enormously, but it does not shrink the cage minimum. Even a bird out for hours still sleeps, rests, eats and spends its unsupervised time in the cage, and routines slip: holidays, illness and busy weeks all produce full cage days. A bird that tolerates those days in a roomy cage stays fit and good-tempered; one in a cramped cage plucks, screams and chews destructively, and those habits outlast the busy week.
Choosing Between Cages That Both Claim to Fit
Choosing between two cages, favour width first, then depth, then height, for an Alexandrine parakeet. Width gives the horizontal wing stretch and short flights this species uses most; height matters mainly to keep the tail clear and let the bird sit above eye level if it prefers. A play-top or an attached stand is a bonus, never a substitute for internal room. Check door size too: a large access door makes cleaning, perch changes and calmly returning a big parakeet far easier, and you will do all three for decades with this long-lived bird. KinsLe Family Sharing keeps the Alexandrine's cage dimensions, perch plan and chewing-toy rotation on a shared profile, so anyone upgrading its setup starts from the real measurements.
