(20") We teased our engineers about pocket-protectors and they came back with the new Pelican 0350 Cube Case. Its so square we thought they were having one on us. Then we showed it around and realized they are on to something. Extra deep so you can layer foam or padded dividers (it is like a split level condo for gear). Or empty it out and drop in one big-ass thingamajig. Which is why it has those gorilla-sized handles! A man on each side with a double hand hold each to heave those heavy loads.
