Their height, however, stands slightly taller, with most reaching about 7 or 8 inches.

A. Genetic Factors and Breed Variations

Like many creatures, Cockatiels’ size and growth are significantly influenced by their genetics. Different Cockatiel subspecies might display minor size variations. For instance, the Lutino Cockatiels can be fractionally larger than their cousins.
