Estimate a minimum cage footprint from a bird's wingspan.
A bird needs room to spread its wings fully, so the minimum cage length is about two and a half times its wingspan and the height about one and a half times. Cramped cages stress birds and prevent proper wing and tail health, so a wingspan-based minimum is a useful sizing starting point.
