The Best Suitcases: Hardshell vs Softside Luggage
The best suitcase is the one that meets carry-on size by airline rules for the trips you take, and passes the gate without a fee. Carry-on size limits differ between US and international airlines, and a bag that's fine on one flight can cost you on the next. This guide sets out typical carry-on size limits by airline type, explains the 22 × 14 × 9 standard, shows a size that fits almost everywhere, and settles hardshell vs softside luggage for each suitcase size.
Key Takeaways
- The common US carry-on size is 56 × 36 × 23 cm (22 × 14 × 9 inches), including wheels and handles.
- Many international airlines allow around 55 × 40 × 20 to 23 cm, often with a 7 to 10 kg weight limit.
- A bag of about 55 × 35 × 20 cm fits almost every airline's carry-on size.
- Softside bags squeeze into sizers more easily; hardshells must fit exactly.
- Always check your airline's own rules before you fly.
Carry-On Size by Airline Type
Carry-on size limits change often and without much notice. This table groups typical carry-on size by airline type, checked in September 2026. Confirm your airline's current rules when you book and again before you fly.
| Airline type | Typical carry-on size | Weight limit | Checked at the gate? |
|---|---|---|---|
| United States, full-service | 56 × 36 × 23 cm (22 × 14 × 9 in) including wheels and handles | Rarely weighed | Checked more often, with automated sizers at some airports |
| United States, low-cost | About 56 × 36 × 23 cm | Rarely weighed | Strictly; the carry-on is usually a paid extra |
| Europe, full-service | Commonly 55 × 40 × 23 cm | Around 8 kg is common | Sometimes, on busy flights |
| Europe, low-cost | Commonly 55 × 40 × 20 cm | Around 10 kg is common | Strictly; the larger bag often needs a paid fare |
| Middle East and Asia, full-service | About 55 × 38 × 20 cm to 56 × 36 × 23 cm | About 7 kg is common | Weight is often checked |
| Asia, low-cost | About 56 × 36 × 23 cm | Often 7 kg, strictly weighed | Strictly |
| Small regional aircraft | Overhead bins may be too small | Varies | Bags may be taken at the aircraft door |
Weight limits matter internationally
US airlines rarely weigh carry-on bags, but many international airlines do, often capping them at about 7 to 10 kg. That makes your suitcase's empty weight important: a 3 kg bag leaves only 4 kg for your belongings under a 7 kg limit.
Who checks at the gate
Low-cost airlines check carry-on size most strictly, because an oversized bag becomes a paid one, often at a higher price at the gate. Automated sizers are also spreading at some major airports. Assume your bag may be measured.
22 × 14 × 9 Luggage: The US Standard Explained
The most common US carry-on size is 22 × 14 × 9 inches, or about 56 × 36 × 23 cm. The key detail most people miss is that this includes wheels, handles and any outside pockets. A suitcase sold as "22 inches" may measure more once its wheels and handle are included, so always check the full outside dimensions.
International Carry-On Size
International carry-on size limits are often a little different. Many European airlines allow around 55 × 40 × 20 to 23 cm, and many airlines in the Middle East and Asia allow around 55 × 38 × 20 cm to 56 × 36 × 23 cm. International airlines are also more likely to weigh your bag. A US-sized carry-on can be a centimeter or two too deep for some international limits.
A Carry-On That Fits Almost Everywhere
If you fly US and international airlines, look for a suitcase of about 55 × 35 × 20 cm, including wheels and handles, weighing 2.5 kg or less empty. It fits within the common US carry-on size, the common European limits and most Asian limits, and leaves room under a 7 kg weight cap.
Will My Suitcase Fit in the Overhead?
Use this four-step check before you travel:
- Pack the suitcase as you would for the trip, without using the expansion zip.
- Measure height from the floor to the top of the handle, including the wheels.
- Measure width and depth at the widest points, including pockets and handles.
- Weigh it packed if you're flying an airline with a carry-on weight limit.
If it meets your airline's carry-on size when packed, it's designed to fit the overhead bin. On small regional aircraft, bags may be taken at the aircraft door and returned on arrival.
Hardshell vs Softside for Carry-On Size
The hardshell vs softside choice matters most when it comes to carry-on size, because it decides how forgiving your bag is at the sizer.
| Factor | Hardshell | Softside | Better for carry-on |
|---|---|---|---|
| Fitting a sizer | Rigid; must fit exactly, wheels included | Can squeeze in if slightly full | Softside |
| Empty weight | Polycarbonate is moderate; aluminum frames are heavy | Usually lightest | Softside |
| Expansion zip | Often adds depth that can break the limit | Same risk if expanded | Keep either unexpanded |
| Outside pockets | Rare, unless front-opening | Standard | Softside |
| Protecting contents | High | Lower | Hardshell |
The expansion zip trap
An expansion zip adds several centimeters of depth, which can take a bag that meets carry-on size limits over them. Use it on the way home only if you're checking the bag, and keep it closed for carry-on.

Hardshell vs Softside Luggage: Which Makes the Best Suitcase?
The hardshell vs softside luggage question has a different answer at each suitcase size, because a carry-on and a large checked case face very different journeys.
| Suitcase size | Best choice | Why |
|---|---|---|
| Carry-on (about 55 cm) | Softside | It squeezes into sizers and full bins, and front pockets help at security |
| Medium checked (about 65 cm) | Either | Choose hardshell for protection or softside for lighter weight and expansion |
| Large checked (about 75 cm) | Hardshell (polycarbonate) | Big checked bags take the roughest handling, and a shell protects what's inside |
What makes the best hardshell suitcase
- Polycarbonate shell: flexes under impact and springs back, unlike brittle ABS.
- Matte or textured finish: hides scuffs far better than a glossy shell.
- A 50/50 or front opening: a front opening gives the quick access hardshells usually lack.
- A TSA-approved lock and a strong frame or zip: the shell is only as secure as its closure.
What makes the best softside suitcase
- Heavy, tightly woven fabric: high-denier nylon resists tears and abrasion.
- Reinforced corners and sturdy zips: the parts that fail first.
- Useful front pockets: for a laptop, documents and liquids.
- An expansion zip: handy for checked trips, kept closed for carry-on.
The trade-off in one sentence
In the hardshell vs softside luggage decision, hardshell buys protection and weather resistance, while softside buys lightness, flexibility and pockets. The best suitcase is the one whose strengths match where it travels: in the cabin or in the hold.
The Best Suitcases by Trip Length
The best suitcase depends on how long you travel. Here's a guide to sizes.
| Size | Typical height | Trip length | Watch out for |
|---|---|---|---|
| Carry-on | Around 20 inches, about 55 cm tall | 1 to 4 nights | Must meet your airline's carry-on size |
| Medium | Around 24 inches, about 65 cm tall | 5 to 10 nights | Checked; mind the weight limit |
| Large | Around 28 inches, about 75 cm tall | 10 nights or more | Checked; easy to overpack past 23 kg |
A note on inch labels
Suitcase sizes in inches often describe the body only, not the wheels and handle. Two "20-inch" suitcases can differ by several centimeters in total height, so always compare full dimensions with your airline's carry-on size before buying.
What Makes the Best Suitcase
- Light empty weight: especially for carry-on and weight-limited fares.
- Four spinner wheels: easy to steer through airports.
- A TSA-approved lock: security staff can open it without breaking it.
- A sturdy telescopic handle: little wobble means a longer life.
- A useful interior: compression straps, a divider and zip pockets.
- Clearly stated full dimensions: so you can check carry-on size before you buy.
Packing a Carry-On to the Limit
- Use packing cubes: they compress clothes and keep the bag from bulging past its carry-on size.
- Roll soft items: rolled clothes fill gaps and crease less.
- Wear your bulkiest items: travel in your heaviest shoes and jacket.
- Check the liquids rules: many airports still limit liquids to small containers in a clear bag, though rules vary by airport, so check before you fly.
- Leave the expansion zip closed: it keeps the bag within its stated dimensions.
A well-packed carry-on stays within its limits and still holds everything for a short trip.
Personal Item and Carry-On Together
On most full-service fares you can bring a carry-on and a smaller personal item that fits under the seat. Pack your valuables, medication and chargers in the personal item. For under-seat limits, see our personal item bag guide.
