Tub height compatability

Can you guys list off hand the tubs that are compatible in height?
Im gonna be building some racks and I wanna be able to use a larger tub sideways or two smaller tubs straight.

Example : sterilite 32qt and 15qt are the same height (can use one 32qt sideways in a shelf or 2 15qt's straight. get what I mean?

I would love to make a 41qt sideways rack but still be able to use 2 smaller tubs straight or maybe even 3 smaller ones for hatchlings on the same size shelf.

well
my rack is 32 sideways, and two 15s straight, so u got that right

i dont think there is any half sizes for a 41 qt, personally, itd be better to have 41 quarts if u do to have them go in straight cause thatd be a pain in the but to pull out all the time
