What Goes in Each Packing Cube? A Simple 3-Cube Formula

Three cubes, three clear jobs. Use this simple formula to organize the little things, tops and light layers, and bulkier pieces so everything in your suitcase has a home.

Three Cram packing cubes sorted by bottoms, tops, and small items for a three-day trip

Packing cubes work best when each one has a job. Otherwise, they’re just smaller bags to rummage through.

Our system is simple: use the small for little things, the medium for everyday layers, and the large for heavier pieces. Three cubes, three clear jobs and significantly less hotel-room archaeology.

What Goes in Each Packing Cube?

Here’s the quick version:

Small Cube: Socks, underwear, swimsuits and loose essentials
Medium Cube: Tops, dresses and light layers
Large Cube: Pants, denim, jackets and heavier knits

The exact contents will change with the destination, weather, and length of your trip, but giving each cube a category makes packing and unpacking much easier.

What to Pack in a Small Packing Cube

The Tiny-Things Wrangler

The best things to pack in a small packing cube are socks, underwear, swimsuits, sleepwear, scarves, and the loose extras that would otherwise disappear into the corners of your bag. Think of it as the suitcase catch-all, minus the chaos.

The Small Cube also works inside a tote, backpack, or roomier purse. Use it to keep charging cables and adapters together, or turn it into an in-flight pouch for a book, your passport, headphones, an eye mask, lip balm, medication, and anything else you’d like to keep within reach. Just keep liquids and fragile items somewhere more secure. No digging through the overhead bin midflight.

What to Pack in a Medium Packing Cube

The Overachiever

The Medium is the most versatile cube in the set. Use it for T-shirts, tanks, button-downs, dresses, pajamas, light sweaters, and other everyday layers.

Roll or fold each piece to roughly the width of the cube, then stack everything vertically so you can see your options instead of excavating through a pile of clothes. This works especially well for pieces you’ll mix and match throughout the trip.

Because the Medium handles so many categories, it’s also the first extra cube we reach for when we want more separation. Use a second one to give pajamas, dresses, workout clothes, or dry worn laundry their own lane. You can add an extra Medium when you shop the 3-Piece Set.

What to Pack in a Large Packing Cube

The Heavy Lifter

The Large works best when it has one clear job: carrying the heavier stuff. Fold pants and denim to the cube’s width, place the sturdiest pieces on the bottom and layer softer knits on top.

Keep shoes outside the cube in a shoe bag along the edge of your suitcase. Your clothes will stay cleaner, and you won’t sacrifice valuable cube space. Pack the Large flat near the wheel end of your suitcase to keep the weight anchored and the bag balanced.

And despite our name, stop before the zipper has to fight for its life. A little breathing room makes the cube easier to close, carry, and unpack.

How Many Packing Cubes Do You Need?

For most trips, three packing cubes are a useful starting point. A small, medium, and large cube can organize the major clothing categories without turning your suitcase into a complicated filing system.

For longer trips or travelers who prefer more separation, add another Medium. It’ll give you room to separate outfits, activewear, sleepwear, or worn clothes without introducing an entirely new packing system.

Should You Roll or Fold Clothes in Packing Cubes?

Both methods work. The goal is to match the width of the cube and arrange your clothes so you can see what you packed.

Rolling works well for T-shirts, tanks, pajamas, and other soft pieces. Folding is usually better for denim, structured clothing, and heavier knits. Whichever method you choose, avoid stacking everything flat from bottom to top. A vertical arrangement makes individual pieces easier to find and remove.

The Three-Cube Formula

Packing doesn’t need seventeen categories and an elaborate spreadsheet. Give each cube a job:

Small: The little things
Medium: Tops and light layers
Large: Bottoms and bulkier pieces

Once everything’s in place, packing’s faster, unpacking’s easier and fewer socks vanish into the corners of your suitcase.
