Cubes for a carry-on
Monos says its Set of Four fits all its Carry-On sizes and its Set of Six all its Check-In sizes. Its Carry-On is 22 x 14 x 9 in outside, wheels and handles included.
Cubes from another maker may fit differently. Lay the cubes out against your suitcase’s inside before you buy a set: a cube taller than the case is deep won’t close flat.
Liters
Eagle Creek’s Pack-It Reveal cubes are S 3 L, M 7 L and L 12 L, by its own calculation from each cube’s size. For a suitcase’s liters, see suitcase size in liters.
