The short answer: To pack a carry-on for a week, choose a 35-40 liter bag, plan a capsule wardrobe of mix-and-match pieces, roll your clothes, use packing cubes, and limit toiletries to travel sizes. This guide breaks down each step so you travel light and avoid checked baggage fees.
Your first step is picking a bag that fits airline overhead bins. Most international airlines allow 55 x 35 x 25 cm (21.5 x 13.5 x 10 inches), but budget carriers like Ryanair or EasyJet have stricter limits. Check your airline’s website before you buy. For a week, a 35-40 liter backpack or a 21-inch rolling suitcase works well. Backpacks are easier for stairs and cobblestones, while rollers are better if you have back issues.

Don’t pack for every day individually; pack mix-and-match pieces that create multiple outfits. Aim for 5-7 tops, 3-4 bottoms, and 1-2 layers. For example: 3 pairs of pants (jeans, chinos, comfortable travel pants), 5 shirts (2 casual, 2 dressier, 1 t-shirt), 1 lightweight sweater or jacket, and 1 pair of comfortable shoes plus 1 dressy pair. Stick to a color palette (like navy, gray, white, and one accent) so everything coordinates. This reduces bulk and decision fatigue.
Rolling your clothes saves space and reduces wrinkles. For wrinkle-prone fabrics like linen, use the ‘bundle wrap’ method: lay a large item (like a jacket) flat, place your rolled clothes in the center, and wrap the jacket around them. This creates a compact bundle that minimizes creases. Use this technique for 80% of your clothing; keep delicate items in a separate packing cube.
Packing cubes are a game-changer. They compress your clothes and keep your bag organized. Use one cube for tops, one for bottoms, one for underwear/socks, and one for electronics/cables. For bulky items like a down jacket or sweater, use a vacuum compression bag (or a roll-up version) to squeeze out air. This can cut volume by 30-40%. Just be careful not to overstuff your bag past airline size limits.
If you’re flying in the US, remember the 3-1-1 rule: all liquids, gels, aerosols, creams, and pastes must be in containers of 3.4 ounces (100 ml) or less, all placed in a single quart-sized clear plastic bag. Travel-sized bottles are your friend. To avoid leaks, place the bag in an outer pocket or a separate pouch. Consider solid toiletries: shampoo bars, conditioner bars, deodorant sticks, and toothpaste tablets are TSA-friendly and save space. For a week, you only need small amounts; most hotels provide basics if you forget.
Shoes are heavy and take up space. Wear your bulkiest pair on the plane, and pack only one extra pair (or two if you need dress shoes). Stuff socks or small items inside shoes to use every inch. For jackets, either wear them or roll them into a compression bag. If you need a formal outfit, consider wearing the jacket on board and packing the rest.
Pack a compact charger, a power bank (under 100Wh for airlines), and necessary cables. Use a small electronics organizer to keep cords from tangling. For a week, you don’t need a laptop if you can manage with a tablet or phone. Remember to bring a reusable water bottle (empty when going through security) and a lightweight daypack for excursions.
On travel day, wear your heaviest and bulkiest items: your jeans, a jacket, and your largest shoes. This not only saves space in your carry-on but also keeps you warm on the plane. Many seasoned travelers also layer, peeling off layers once seated. This simple tactic can free up 15-20% of your bag’s space.
Pack your bag to 80% capacity. This leaves room for any purchases you make. If you know you’ll buy a lot, take an extra foldable duffel that can serve as a personal item on the return flight. Alternatively, plan to do laundry mid-trip; a sink wash with travel detergent can refresh clothes, allowing you to pack fewer items.
Before you leave, do a final check: all liquids in a clear bag, batteries in your carry-on (not checked), and any sharp objects in your checked luggage (if you have one). Weigh your bag on a luggage scale; most airlines have a 7-10 kg (15-22 lbs) limit for carry-ons. If you’re over, wear a few layers or move heavy items to your personal item. And remember, you can always buy toiletries at your destination if you need them.
Can I pack a week’s worth of clothes in a 22-inch carry-on? Yes, with careful planning. Use compression packing cubes and roll your clothes. You can fit about 5-7 outfits, plus shoes and toiletries, if you choose lightweight fabrics and avoid bulky items.
How many pairs of shoes should I pack? For a week, two pairs max: one comfortable walking shoe (wear on plane) and one dressier option. If you need athletic shoes, wear them on the plane or stuff them with socks.
Do I really need a packing cube? Not strictly, but they help compress clothes and keep you organized. If you don’t want to buy them, use resealable plastic bags to compress items like sweaters.
