Traveling with only a carry-on can make trips simpler. You skip the baggage carousel, avoid checked bag fees on many fares and move through stations and streets more easily. The trade-off is that every item has to earn its place.
This guide gives you a flexible carry-on packing list, a simple clothing formula and tips for fitting everything in. Rules vary by airline, fare type and route, so always check your airline’s size and weight limits before you pack.
Start With the Rules
Before you choose what to pack, confirm:
- Carry-on size limits. Many US airlines list carry-on limits around 22 x 14 x 9 inches including wheels and handles, but limits differ, especially on international and budget carriers.
- Weight limits. Some airlines, particularly outside the US, set carry-on weight limits.
- Personal item allowance. Many fares allow a small personal item that fits under the seat. Some basic fares do not include a full-size carry-on.
- Liquids rules. In the US, the TSA 3-1-1 rule applies to most liquids in carry-on bags. See our guide to travel toiletries and liquids.
Knowing these limits shapes everything else, including which bag you bring. See carry-on vs. checked bag if you are deciding between the two.
Choose the Right Bag
A carry-on can be a wheeled suitcase or a travel backpack.
- Wheeled carry-ons roll easily through airports and keep weight off your shoulders.
- Travel backpacks handle stairs, cobblestones and crowded trains better.
Pair your main bag with a personal item for things you want at your seat. See how to choose a travel backpack and our personal item bag guide.
A Simple Clothing Formula
Clothing takes up most of the space. A formula keeps you from overpacking. For a trip of about one week:
- Tops: 4 to 5
- Bottoms: 2 to 3
- Underwear: 5 to 7, or fewer if you plan to wash
- Socks: 4 to 5 pairs
- Sleepwear: 1 set
- Layer: 1 sweater or fleece
- Outer layer: 1 jacket suited to the weather
- Shoes: 2 pairs, one worn and one packed
For longer trips, plan to do laundry rather than packing more. Many travelers pack for about a week and wash as needed.
Choose a Color Palette
Pick two or three base colors that work together so every top matches every bottom. Neutral colors hide wrinkles and stains and mix easily.
Favor Versatile Fabrics
Fabrics that resist wrinkles, dry quickly and handle odors well, such as merino wool and many synthetic blends, can be worn more than once and washed in a sink. Heavy denim and bulky knits take more space.
Wear Your Bulkiest Items
Wear your heaviest shoes and jacket on travel days to free up space in your bag.
Toiletries
Keep toiletries minimal:
- Toothbrush and toothpaste
- Deodorant
- Shampoo and conditioner, or solid bars
- Face wash and moisturizer
- Sunscreen
- Razor, following airline and TSA rules
- Hairbrush or comb
- Any medications, in original containers where possible
- Small first-aid basics such as bandages
Many hotels provide basics like shampoo and soap, so check before you pack them. Solid toiletries do not count toward liquid limits in many places.
Tech and Chargers
- Phone and charger
- Charging cable for each device, or a multi-device charger
- Power bank, carried in the cabin, since most airlines prohibit spare lithium batteries in checked bags
- Plug adapter for international trips
- Headphones
- E-reader or tablet if you use one
See travel adapters and chargers for help choosing.
Documents and Essentials
- Passport or ID
- Boarding passes, digital or printed
- Credit or debit cards and some local currency
- Travel insurance details if you have a policy
- Copies of important documents stored separately or securely in the cloud
- Accommodation and transport confirmations
- Pen for arrival forms
Personal Item Essentials
Keep these within reach at your seat:
- Documents and wallet
- Phone, charger and headphones
- Medications
- A light layer for cold cabins
- Empty water bottle to fill after security
- Snacks
- Comfort items. See our long-flight comfort kit.
Packing Techniques
Rolling vs. Folding
Rolling works well for soft, casual clothing and can reduce some wrinkles. Folding works better for structured items like button-down shirts. Many travelers combine both.
Packing Cubes
Packing cubes group items and make unpacking easier. Compression cubes can save some space. See are packing cubes worth it?
Fill Empty Spaces
Stuff socks inside shoes and use gaps along the edges of the bag for small items.
Pack Heavy Items at the Wheels or Back
In wheeled bags, place heavy items near the wheels. In backpacks, keep heavy items close to your back for better balance.
What to Leave at Home
- “Just in case” outfits
- More than two pairs of extra shoes
- Full-size toiletries
- Bulky towels, unless your lodging does not provide them
- Items you can easily buy at your destination
Laundry on the Road
For trips longer than a week, plan laundry:
- Sink washing with a small amount of travel detergent
- Laundromats in many cities
- Hotel or lodging laundry services
- Vacation rentals with washing machines
Quick-drying clothing makes sink washing easier.
A Sample One-Week Carry-On
| Category | Items |
|---|---|
| Tops | 4 to 5 shirts |
| Bottoms | 2 pants or shorts, 1 optional skirt or dress |
| Layers | 1 sweater, 1 jacket worn |
| Underwear and socks | 5 to 7 each |
| Shoes | 1 worn, 1 packed |
| Toiletries | Liquids bag plus solids |
| Tech | Phone, chargers, power bank, adapter |
| Documents | ID, cards, confirmations |
Adjust for climate, activities and how often you plan to wash.
Adjusting the List for Different Trips
Business Trips
Add one or two outfits suited to meetings and choose shoes that work with both business and casual clothing. A garment folder can help keep shirts and blazers smoother. Pack your laptop, charger and presentation materials in your personal item.
Cold-Weather Trips
Wear your heaviest coat and boots on the plane. Thin base layers made of merino or synthetic fabrics add warmth without bulk. A hat, gloves and a scarf take little space and make a big difference.
Beach Trips
Swimwear, sandals and lightweight clothing pack small. Pack sunscreen as a solid stick or in travel-size containers, or buy it on arrival.
