questions on building a rack

[Stewart_Reptiles]

hi, i am going to build a rack for about 6 juvie ball pythons. i was thinking on building one rack with smaller tubs on top and larger ones for adults on bottom. just a question on what size tubs to get for the juvies and what for adults. they are not hatchlings by the way. so my questions are what size tubs for juvies and then adults.
Thanks

This is the tub size I use
