Ringnecks and their needs

[Becl]

I am considering a ringneck for a second bird. Other is a sweet Jenday Conure (Jenny).
I am trying to buy another cage but it giving different measurements for the bars. What should I be looking for with bar measurements. The conure came with her cage.

I believe A Ringneck needs the same bar spacing as a conure; 1/2 inch to 5/8 inch wide
