I've been looking at carryons and am schtumped by what to do with dimensions. The " 20"" models don't include the wheel height , so several that looked good at TJMaxx are 23-almost 24" measured from the floor up.
If these had to " fit in the box" , would they? ( thinking 22"). Also, a nice gray Wenger bag is clearly deeper and spacious, about 9" of oacking depth compared to about 7" of others, and its exterior depth might push 10" ( ok, 9.5) when packed.
I get how not to overstuff for carryon to limit the bulging depth, but what about the wheeled length thing? Am I being obsessive, or appropriately concerned about lack of standardization and buyer- beware?
