How to pack a suitcase with packing cubes
A suitcase opens flat and packs in layers, which is exactly what cubes are built for. Here's the step-by-step method to turn a suitcase into tidy, findable drawers that don't shift in transit.

A suitcase is the ideal home for packing cubes: it opens flat, it packs in layers, and its rectangular interior is exactly the shape cubes are built to fill. The trick is treating the cubes as a system rather than as random pouches — sort by category, fill each cube firm, then load them in a deliberate order so the case is balanced, findable and stays put in transit. Here is the method, step by step.
Step 1 — Sort by category, one job per cube
Give each cube a job: tops in one, bottoms in another, a small cube for underwear and socks, and a separate small one for tech or toiletries. Sorting by category (not by day) is what makes cubes findable — you always know which cube holds a clean shirt and can pull just that one. Match cube size to the load; our sizes guide maps sizes to what fits inside.
Step 2 — Fold or roll, then fill firm
Roll soft casual clothes for density, fold structured pieces flat to avoid creases (details in the folding guide). Pack each cube full and flat so nothing shifts — a firm cube holds its shape and prevents the in-transit movement that causes wrinkles. Do not overstuff past the zipper; if it will not close easily, move a piece to another cube.
Step 3 — Load heaviest cube at the wheels
In a roller suitcase, place the heaviest cube (usually bottoms and shoes) against the wheel end — the side that sits at the bottom when the case stands upright. Keeping the weight low makes the case stable and easy to wheel. Lay the cubes flat in layers rather than standing them on end.
Step 4 — Square the cubes so they tessellate
Arrange the cubes so they fit together with no gaps — gaps are where things slide and shift. Because cubes are rectangles, they tessellate neatly; slot soft items (a packed jacket, a shoe bag, socks) into any corners the rectangles leave behind so the whole layer is snug.
Step 5 — Reserve a cube for laundry
Leave one cube empty on the way out (or bring a dedicated laundry bag). As clothes are worn, they move into the dirty cube so clean and worn never mix — and repacking to come home is just as organized as leaving. On longer trips, dedicate two. More on the system in how to use packing cubes.
A quick note on carry-on suitcases
The method is the same for a carry-on, just tighter — slim cubes that stack flat help you use every inch of a cabin bag. See the dedicated carry-on guide and the carry-on cube picks.
Questions
Frequently asked
How do you pack a suitcase with packing cubes?
Sort clothes by category into separate cubes, pack each cube full and flat, place the heaviest cube at the wheel end, square the cubes so they tessellate with no gaps, and reserve one cube for laundry. That turns a suitcase into tidy, findable, balanced drawers.
Should heavy items go at the bottom or top of a suitcase?
At the bottom — the wheel end of a roller — so the weight sits low and the case is stable and easy to wheel. Lighter cubes and crease-prone folded items go on top.
How many packing cubes fit in a suitcase?
A carry-on comfortably holds a three-cube set plus shoes and a toiletry bag in the gaps; a large checked case holds six or more. See our how-many guide for the chart.
