What Bar Spacing Size Should My Pet Bird's Cage Have? Guidelines & Chart Below

Bar spacing is the most vital factor to consider when selecting a bird cage. Choosing a cage with bar spacing that's too wide could result in your bird escaping from its cage, or worse yet, injuring itself when trying to escape!

It is also crucial to select a cage that's adequately sized regarding the internal dimensions. Getting the overall cage dimensions correct is extremely important to the health of your bird as well...

This makes for an interesting dilemma when shopping for a bird cage:

You want the cage to be large enough for your bird to spread his wings, but the bar spacing can't be too wide either. And generally, as the cages increase in size, the bar spacing goes up as well.

So How Do I Pick The Right Cage?
