This also gives you more versatility when switching luggage. Larger packing cubes may be difficult to match with different sizes of luggage.

This works well for long-term trips that requires you to mix and match many of the same pieces.

For example, if you’re going swimming one day and hiking the next, you could pack one cube with your swimsuit, goggles, cover-up, flip-flops, and a change of clothes, and another cube with a T-shirt, shorts, socks, and a light jacket for hiking.

For example, you could designate a color for each person and pack their all of their things into cubes of the same color. This could be especially helpful for parents packing for their young children. You could also designate a color for different categories of clothing, such as dressy and casual, or clothes for warm weather and clothes for cool weather.

This is especially helpful for extended trips that require more clothing options.

This technique works best on items like blazers, dressy pants, dressy skirts, and starched shirts. [16] X Research source

Keeping your laundry in a packing cube will help keep dirty clothes out of the way, separate from the clean clothes, and compressed so they won’t take up too much space in your bags. A double-sided packing cube is perfect for storing laundry. [20] X Research source

If you have trouble fitting the packing cubes into your suitcase, go for flexible ones over structured ones. This will let you fit the cubes into the contours of the suitcase more easily.
