Suitcases feel full when clothes are stacked, rummaged through, then shoved back in. And that’s why the Japanese packing hack in 2025 is worth trying: fold each garment so it can stand upright, then pack those folds like files.
This upright style is closely linked to Marie Kondo’s KonMari method. Her packing advice is to store folded items vertically rather than in a pile, so you can see what you brought without pulling everything out.
Why upright folding cuts “just in case” packing
Overpacking usually starts with doubt. If you cannot see what is in your case, you add extras to cover imagined gaps. Upright folding clears that fog. Open the case and your options are visible, edge-on, with each piece reachable without disturbing the rest.
It also helps clothes keep their shape. Marie Kondo explains that vertical storage prevents the bottom of a stack from being crushed and makes tidying mid-trip easier.
A workable routine (no special gear required)
- Begin with an edit. Lay everything out, then remove duplicates. Two “nice” tops often do the same job. Keep to a tight palette so most items go with most others.
- Fold into neat rectangles that can stand up. With tops, fold sleeves in, fold into thirds lengthways, then fold again until the item holds its shape. With trousers, fold in half and bring the hems up in sections, again aiming for a stable block.
- Pack upright in rows. Put heavier items near the wheels end of a roller case. Tuck socks and chargers into corners, ideally in a small pouch.
- Keep essentials accessible, not buried. British Airways notes that cabin bags may need to go in the hold, so medicines and valuables are better kept with you.
- A thin laundry bag for worn clothes stops the case turning into a jumble by day three and speeds up repacking.
Two weeks in a carry-on
A fortnight can fit into cabin luggage if you plan one mid-trip wash. A solid baseline is five tops, three bottoms, one mid-layer, one smarter outfit, sleepwear, and a week of underwear. Wear your bulkiest shoes and outer layer in transit.
Then match your packing to the airline.
easyJet’s free under-seat bag limit is 45 x 36 x 20 cm.
Ryanair’s personal bag allowance is 40 x 30 x 20 cm, with larger cabin bags tied to fare type or add-ons.
Upright folding works best when the case closes without strain.
Hard-shell vs. Soft-shell: Which suits the Japanese method?
Either can work, though they reward different habits. A hard-shell case keeps its geometry, which helps upright folds stay aligned through bumpy transfers.
- Hard-shell luggage is often made from plastics such as ABS and polycarbonate, and durability depends heavily on materials and build quality.
- Soft-shell luggage offers flexibility and handy exterior pockets. The downside is that an overfilled soft case loses its shape, and your “files” begin to lean. If you favour soft-shell, use internal straps and avoid treating expandable sections as free space.
Choosing luggage with a lighter footprint
Better packing should not lead to constant buying. If you are replacing a worn case, look for replaceable wheels, repair options, and a proper guarantee. Many mainstream brands now sell luggage made with recycled materials, including fabrics derived from plastic bottles or reclaimed plastics. If you are searching for sustainable travel luggage UK, those details matter more than a glossy finish.
Strict bag rules also make overpacking expensive. The cheapest advertised cabin bag fees on some budget airlines can be rare, so checking allowances early still pays off.

Frequently Asked Questions
- What is the Japanese vertical folding method for suitcases?
Clothes are folded into compact rectangles that stand upright. You pack them in rows like files, so every item is visible and you can lift one piece out without unravelling the rest. A flat-base case helps keep rows upright. - How can I fit 2 weeks of clothes in a carry-on suitcase?
Plan one wash and pack a capsule: five tops, three bottoms, one mid-layer, one smarter outfit, sleepwear, and underwear for about a week. Wear bulky shoes and a coat on travel days. Quick-dry fabrics make sink washing easier overnight. - How to avoid overweight baggage fees at UK airports?
Weigh your bag at home, then leave a buffer for gifts. Put dense items in your personal bag if your ticket allows. Always check airline size and weight rules before you fly. Reweigh after adding snacks or duty-free. - Are hard-shell suitcases better for organised packing?
Often. Their rigid sides keep the interior stable, which helps upright folds stay upright, especially if you repack often. - Do packing cubes replace the vertical fold?
No. Cubes group items and vertical folding keeps each piece accessible. Used together, cubes act like drawers inside your suitcase.
