Use standard cubes for organization
Standard lightweight cubes make categories easy to find and transfer between a suitcase and a drawer. They are most useful on multi-stop trips or when two travellers share one case.
Use compression selectively
Compression cubes reduce the volume of soft, lofty clothing, but they do not reduce weight and can create a dense, awkward block. They offer little benefit for jeans, structured garments, shoes, or already compact fabrics.
Match the cube to the bag
- Measure the interior rather than relying only on litre capacity
- Use fewer larger rectangles in a boxy suitcase
- Use flexible pouches in a tapered backpack
- Keep frequently used items outside the deepest cube
- Avoid buying a set with shapes your bag cannot use
Skip cubes when simplicity wins
For a one-night trip, a small personal item, or a bag with excellent built-in compartments, cubes can add weight and seams without improving access. Test the same list with and without them before deciding.
