New Rack Questions

[dfitzsim]

I'm building a rack to house my corns, cresties and leos. I'm looking at several different sized sterilite storage boxes. Can you guys let me know if you think these are appropriately sized?

4 1/2 quart - 13" long, 7 1/2" wide, 3 1/2" high.
28 quart - 23" long, 16"wide, 5 1/2" high.
52 quart - 22 1/2" long, 16" wide, 12" high
73 quart - 22 1/2" long, 16" wide, 15" high

I was going to use the 4 1/2 quart for babies, 28 quart for a breeding group of leo's and maybe for my individual corns. Do you think this is big enough for the corns or should I find something bigger? Also should I use the 52 quart or 73 quart boxes for my breeding cresties? The only difference is 3 more inches of height.

Thanks
Don
