Bird Cage Size

Estimate a minimum cage footprint from a bird's wingspan.

About Bird Cage Size

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.

Formula

Bird Cage Size

Cage length ≥ 2.5 x wingspan; height ≥ 1.5 x wingspan

wingspan

Assumptions and limits

  • The result is derived only from the single input listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
