Carry-on packing list for a week: what actually fits

Five of each daily item, two pairs of shoes and one wash halfway through: that's the heart of a carry-on packing list for a week. Wear your bulkiest things on the plane, pack liquids to the strictest rule, and check your airline's bag size for this exact booking. Everything else is detail.

A week in a cabin bag sounds tight until you've done it once. After that it feels like a small superpower. You walk off the plane and straight out of the airport, nothing gets lost in transit, and mornings are quicker because there's less to choose from.

The trick isn't clever folding. It's counting. Most overpacking comes from packing one of everything for every day, plus a few "just in case" extras, so this guide gives you the numbers instead.

First, how big can your carry-on be?

Each airline sets its own cabin bag rules; there's no global standard. Plenty land somewhere around 55 × 40 × 20cm, but a bag that's fine on one airline can be too big on another flying the same route. Wheels and handles count.

Weight limits vary even more. Some airlines only check size, while others weigh cabin bags at the gate, often at 7kg or 10kg. On many low-cost airlines only a small under-seat bag is free, and the bigger overhead bag costs extra.

So before anything else, measure your bag once, write the numbers down, and compare them with your airline's own website for this booking. Not a blog, not a forum, and not this page.

The one rule that makes it fit: wash once

Pack one set of daily clothes per day and a week needs eight of everything: seven days plus a spare. That won't fit comfortably in most cabin bags.

Plan one wash in the middle instead. A sink and a bar of soap will do, or a hotel laundry, or a laundrette. With a wash on day four, the longest run you have to cover is four days. Add one spare and you need five of each daily item, not eight.

It's the same maths Neatly Packed uses on Premium when you tell it there's laundry on your trip: it covers the longest stretch between washes, plus one for the wash day itself. For a quick list without the app, our free packing list maker gives you a counted checklist in about a minute.

The carry-on packing list for a week

These counts assume seven nights, mild or warm weather and one mid-trip wash. Wear the bulkiest items on the plane. Heading somewhere hot? Our Caribbean island packing list adds the beach and rain extras.

Clothes

• 5 pairs of underwear
• 5 pairs of socks (skip most of these if you'll live in sandals)
• 5 tops or t-shirts, in colours that all go with each other
• 2 pairs of trousers, shorts or skirts, plus the pair you travel in
• 2 to 3 underlayers, such as bras, vests or undershirts
• 1 warm layer, like a light jacket, hoodie or cardigan, worn on the plane
• 1 set of sleepwear (a week doesn't need two if you're washing anyway)
• 1 outfit for a nicer dinner, only if you know you'll need it
• Swimwear, if there's a pool or beach
• A packable rain jacket, if the forecast says so

Shoes

Shoes are the heaviest, most awkward things you'll pack, so two pairs is the sweet spot for a week.

• 1 pair of comfortable walking shoes, worn on the plane
• 1 lighter pair: sandals, flip flops or flat shoes that pack flat

Toiletries

• Toothbrush and toothpaste
• Deodorant (a stick or solid avoids the liquids question entirely)
• Shampoo, soap and face care, in small containers or solid bars
• Hairbrush or comb
• Razor, if you use one
• Sunscreen and lip balm
• A small bag for dirty laundry

Tech

• Phone and phone charger
• Power bank, charged
• Headphones or earbuds
• A plug adapter if your destination uses different sockets

Documents, money and health

• Passport or ID, whichever your trip needs
• Travel insurance details, saved offline
• Bank card, plus a backup card packed separately if you have one
• Some local cash for places that don't take cards
• Booking confirmations, printed or saved offline
• Any medication you take, with a few days' spare

For the journey

• An empty reusable water bottle to fill after security
• A few snacks
• A pen, for arrival and customs forms
• A small day bag or tote that folds flat

Carry-on liquids: pack for the strictest rule

There's no longer one worldwide liquids rule. Many airports still want containers of 100ml or less, all in one clear resealable bag that comes out at security. Some airports with newer scanners allow more and let you leave liquids in your bag. Which one you meet depends on the airport, and sometimes on the lane.

The safe approach: pack to the 100ml rule unless you've checked every airport on your route, and remember that the airport you fly home from may be stricter than the one you left from.

"Liquid" means more than you'd think. Toothpaste, mascara, sunscreen, gel deodorant, lip gloss and even peanut butter all count. Solid shampoo bars, stick deodorant and bar soap don't, which makes them the easiest way to free up space in that little bag. Our guide on how to pack toiletries in a carry-on goes through it item by item.

How to make it all go in

Roll soft things like t-shirts and underwear, which pack small, and fold stiff ones like shirts and trousers flat so they crease less. Stuff socks, chargers and other small bits inside your shoes. It saves space and helps the shoes keep their shape.

Put the heaviest things at the wheel end so the bag stands up and rolls easily. And pick one colour story: if every top goes with every bottom, five tops feel like far more outfits.

Leave a little space, too. You'll almost certainly bring something home.

What to leave at home

These are the things that most often sink a carry-on plan:

• A third or fourth pair of shoes
• Full-size bottles of anything
• A hair dryer, when most hotels have one (check yours)
• A heavy book, when your phone can hold a dozen
• The "maybe" outfit you haven't worn in a year

Always pack the maybe outfit anyway? Our packing style quiz will tell you if you’re a just-in-case packer, with tips for packing lighter.

Forget something small and most places will sell you toothpaste. The only things that are truly hard to replace are your documents, your medication and your cards, so check those twice and let everything else be good enough.

A last check before you zip it

• Is your liquids bag at the top, where you can reach it at security?
• Are your power bank and chargers in the bag that stays with you?
• Does the bag meet your airline's size and weight for this exact booking?
• Are your passport, cards and medication on you, not buried?
