Carry-On Suitcases That Fit the Overhead Bin: Size, Weight, Wheels, and Shells

A good carry-on suitcase saves time and money on almost every trip. It skips the checked bag fee on many fares, avoids the wait at the baggage carousel, and keeps clothes and essentials with you if a connection goes wrong. For a long weekend or a short work trip, a carry-on is often the only bag you need.

Carry-on suitcases look alike in photos, but they differ in size, weight, shell material, wheels, handles, and how much they expand. This guide covers what to check before you buy, how airline size limits work, what the TSA allows in a carry-on, and a range of models from several stores.

Top Carry-On Suitcases

Start with the size limit

The most important number on a carry-on is its outside size. Airlines set their own limits, and they are not all the same. United Airlines, for example, lists a carry-on limit of 22 x 14 x 9 inches (56 x 35 x 23 cm). Many U.S. carriers use similar numbers, but budget airlines and airlines outside the U.S. can be stricter, and some charge extra for any bag that goes in the overhead bin.

Always check the airline's own baggage page before a trip, and measure the bag yourself. Product listings sometimes give the size of the packing space and leave out the wheels and handles, which still count at the gate. A 20-inch or 21-inch suitcase gives a little more room to spare than a 22-inch model, especially on smaller planes and international flights.

Hardside or softside?

Hardside suitcases use a shell of polycarbonate, ABS plastic, or a blend. They resist rain, protect fragile items better, and are easy to wipe clean. Most open like a clamshell into two equal halves, which is handy for keeping clean and worn clothes apart. The trade-off is that they do not flex, so an overstuffed hardside case can be hard to close or squeeze into a tight bin.

Softside suitcases use a woven fabric such as nylon or polyester. They usually have outside pockets for a jacket, a laptop, or a quick-access bag of liquids, and they give a little when the bin is nearly full. They can scuff and absorb water more easily. Many frequent travelers like softside bags for the pockets, while others prefer the neat, protective shell of a hardside case. Both work well, so choose based on how you pack.

Spinner wheels or two wheels?

• Spinner wheels: Four wheels that turn in every direction. The bag rolls upright beside you and glides down narrow airplane aisles. Spinners are easiest on smooth airport floors.
• Two wheels: Inline wheels that roll the bag behind you at an angle. They handle curbs, cobblestones, and rough sidewalks better and take up a little less space inside the bag.
• Wheel quality: Look for smooth, quiet wheels that are set into the corners of the case, where they are less likely to snap off.

Weight and handles

Some airlines limit the weight of a carry-on, and you have to lift the bag into the overhead bin yourself. A lighter empty suitcase leaves more of that allowance for your things and is easier on your shoulders. Check the empty weight in the product listing and compare a few models.

The telescoping handle should lock firmly at more than one height and should not wobble much when fully extended. Top and side carry handles make it easier to lift the bag onto a bin or a car trunk. A handle that sits flat when stowed saves a bit of packing space.

Expandable zippers and packing space

Many carry-ons have an expansion zipper that adds an inch or two of depth. It is useful on the way home when you have picked up gifts or souvenirs. Keep in mind that an expanded suitcase may no longer meet the airline's size limit, so treat the extra room as a backup for trips where you know the bag will be checked.

Inside, look for compression straps or a zippered divider to keep clothes in place, a mesh pocket for small items, and a lining that is easy to wipe out. Packing cubes work well in both hardside and softside bags.

Full-size carry-ons

The Travelpro Maxlite Air V2 is a 20-inch hardside carry-on with an expansion zipper, a good all-around size for domestic and many international flights.

The Samsonite Freeform is a hardshell carry-on with spinner wheels and an expandable design, a solid pick for travelers who want a protective shell.

At Target, the SWISSGEAR Cascade II is a hardside carry-on spinner in black, a practical choice for everyday travel.

Also at Target, the American Tourister Stratum 3.0 is a 20-inch hardside spinner in a bright blue that is easy to spot at the gate.

The Wrangler 22-inch hardside spinner is an affordable option for travelers who want the largest common carry-on size.

Budget carry-ons and sets

The Travelers Club Chicago is a 22-inch expandable spinner in teal, a low-cost pick for occasional trips.

At Walmart, the iFLY Fibertech is a 20-inch hardside carry-on with an expandable spinner design.

The UKEIN 3-piece set pairs a 20-inch carry-on suitcase with a matching backpack, which helps when you also want a personal item that fits under the seat.

What the TSA allows in a carry-on

Size is not the only rule. The Transportation Security Administration's liquids rule lets travelers bring a quart-sized bag of liquids, aerosols, gels, creams, and pastes in a carry-on. Each item has to be in a travel-sized container of 3.4 ounces (100 milliliters) or less. The TSA says to pack anything in a larger container in checked baggage.

Keep that quart-sized bag near the top of the suitcase or in an outside pocket so it is easy to pull out at the checkpoint. Solid toiletries, such as bar soap and solid shampoo, can free up room in the liquids bag. Rules can change, so check the TSA website before you fly, especially for items like medications, batteries, and duty free purchases.

Packing tips for a carry-on

• Roll or fold with cubes: Packing cubes keep outfits together and compress soft clothes.
• Wear the bulky items: Put on the heaviest shoes and jacket for the flight.
• Plan outfits: Pick a small color palette so tops and bottoms mix and match.
• Use the corners: Tuck socks and chargers into shoes and gaps.
• Leave a little room: A bag that closes easily is faster to open and repack at security.

Personal item vs. carry-on

Most airlines allow one carry-on bag for the overhead bin plus one smaller personal item, such as a backpack, tote, or laptop bag, that fits under the seat in front of you. Some basic fares allow only the personal item. Read the fare rules when you book, since the answer affects which bag you should bring.

Caring for your suitcase

Wipe hardside shells with a damp cloth and mild soap, and spot clean fabric bags. Clear hair and grit from the wheels now and then so they keep rolling smoothly. Store the suitcase in a dry place, and keep it zipped so dust does not collect inside. Nesting smaller bags inside a larger one saves closet space at home.

Common carry-on mistakes

The most common mistake is buying a bag by its listed name alone. A suitcase sold as a carry-on may still be too big for a specific airline once the wheels and handle are counted. Another mistake is overpacking the expansion zipper and then being asked to check the bag at the gate. Travelers also forget that a heavy bag has to be lifted overhead. Finally, liquids in containers over 3.4 ounces are a frequent cause of delays at security.

Questions to ask before you buy

• Which airlines do you fly most? Check their size and weight limits first.
• Hardside or softside? Choose protection or outside pockets.
• Where do you walk? Spinners suit airports; two wheels suit rough streets.
• How long are your trips? Short trips rarely need the expansion zipper.

The short answer

For most travelers, a 20- to 22-inch carry-on with smooth spinner wheels, a sturdy locking handle, and a light empty weight covers weekend trips and short work travel. Confirm the size against your airline's current limits, keep liquids to 3.4-ounce containers in a quart-sized bag, and choose hardside or softside based on how you like to pack.
