Packing cubes do not physically shrink your clothes, but they save space by maximizing "spatial efficiency" and eliminating the "dead air" that occurs when clothes are packed loosely. By turning soft, irregular items like shirts and socks into neat, rectangular bricks, you can fit them into your suitcase like a game of Tetris, utilizing corners and edges that usually go to waste. However, if your goal is significant volume reduction, you must use Compression Packing Cubes. These feature a secondary reinforced zipper that squeezes the air out of the fabric, which can reduce the volume of soft items (like t-shirts and sweaters) by 20% to 40%. The downside is that compressed clothes tend to wrinkle more, and it is very easy to accidentally overpack and exceed your airline's weight limit because the bag looks half-empty even though it's already heavy. For most travelers, the real "space-saving" benefit is organizational; you spend less time digging through your bag, which keeps everything flatter and more compact throughout the trip.

Pro Tip: Roll clothes before placing them in cubes for even more space savings. While they won’t magically shrink your clothes, they do optimize how you use available space.
