Packing cubes don't create space on their own; they keep a bag organized, so you can find things fast and keep clothes neat. Compression cubes do save space by zipping down to squeeze out air. A starter set of one large, one medium and one small cube covers a week in a carry-on. Pack one category per cube, roll or fold to the cube's size, and put heavy cubes at the wheel end.
Packing cubes are zippered fabric boxes that turn a suitcase into a set of drawers. They are one of the simplest upgrades for anyone who travels regularly.
What packing cubes do
- Organize: one cube per category means you find things without unpacking everything.
- Compress (somewhat): keeping clothes in a tight, rectangular shape uses space efficiently.
- Make repacking fast: at hotels, the cubes go straight into a drawer and back again.
- Separate: keep clean and worn clothes apart, or split one bag between two people.
Regular vs compression cubes
| Regular | Compression | |
|---|---|---|
| How it works | A single zip around the lid | A second zip squeezes the cube flatter |
| Space saved | A little | Noticeably more |
| Wrinkles | Fewer | More, from pressure |
| Best for | Organizing, shirts and dresses | Bulky knits, base layers, longer trips |
Be careful with compression cubes on weight-limited flights: they let you fit more, which also means more weight.
Which sizes to buy
- Large: pants, sweaters and bulky items.
- Medium: shirts, tops and dresses.
- Small: underwear, socks, swimwear and accessories.
- Slim or extra small: chargers, cables and toiletry overflow.
A three-piece set covers a week in a carry-on. Check the cubes against your bag’s interior dimensions, since a set that doesn’t fit wastes space.
How to pack with cubes
- Plan outfits and lay everything out first.
- Assign one category per cube.
- Roll or fold to the cube’s width so items fill it edge to edge.
- Zip and stand the cubes in the bag like books, or stack them.
- Put heavy cubes at the wheel end of a rolling bag so it stays upright.
- Fill the gaps with shoes, toiletries and soft items.
Materials
Look for lightweight ripstop nylon, sturdy zippers and a mesh panel so you can see what is inside. Some cubes have a two-sided design to separate clean and dirty clothes.
Are they worth it?
For short, simple trips with a small bag, you can manage without. For multi-stop trips, shared luggage or anyone who wants an organized bag, packing cubes are one of the best-value travel accessories you can buy.
Common questions
Do packing cubes save space?
Regular cubes mostly save time and keep things organized, with a little space saved by keeping clothes compact. Compression cubes have a second zipper that squeezes the cube down and can save noticeably more space.
Should I roll or fold clothes in packing cubes?
Either works. Rolling suits soft knits and casual clothes; folding to the cube's width works better for shirts and anything that wrinkles. Most people use a mix.
What size packing cubes should I buy?
A three-piece set with large, medium and small cubes suits most trips. Check that the cubes fit your bag's interior, since sets are often designed for specific luggage sizes.
