Quick answer
The most important spec is the bag’s overall size including wheels and handles. Many US airlines cap carry-ons at 22 x 14 x 9 inches. From our research, the Travelpro Maxlite 5 Compact is the lightest option here (5.1 lb), the Travelpro Platinum Elite Compact Hardside is the most feature-rich, and the Delsey Helium Aero 21″ suits travelers who want a laptop pocket on the front.

What to look for in a carry-on
True overall dimensions
Airlines measure everything: wheels, handles and any bulge from overpacking. Some bags are marketed as “21-inch” while measuring 23 inches tall overall. Always check the overall figure, and remember that using an expansion zipper can push a compliant bag over the limit.
Weight
Many US airlines don’t weigh carry-ons, but many international and low-cost airlines do, sometimes with limits around 7 to 10 kg (15 to 22 lb). Every pound of bag is a pound less of clothes.
Hardside vs softside
Hardside shells (polycarbonate or polypropylene) resist rain and crushing and are easy to wipe clean, but they don’t flex into tight overhead bins and have no outside pockets for quick access. Softside bags are often lighter, squeeze into tight spaces and usually have exterior pockets.
Wheels and handle
Four spinner wheels are easiest in airports. Two inline wheels tend to roll better over cobblestones and curbs and take less space. A sturdy, stable telescoping handle matters more than most people expect.
Warranty
A good warranty is a signal the maker expects the bag to last. Read what’s actually covered: many exclude airline damage or normal wear.

Bags we looked at but didn’t pick
Samsonite Freeform Carry-On Spinner: light for a hardside at 6.5 lb, but Samsonite lists it at 23 x 15 x 9.75 inches, larger than the common 22 x 14 x 9 inch limit. Travelpro Maxlite 5 21″: roomier at 46 L, but 23 inches tall overall per Travelpro. Both may be fine on airlines with larger allowances, so check yours.
Common mistakes when buying a carry-on
- Trusting the “21-inch” name instead of the overall dimensions.
- Ignoring empty weight when flying airlines with carry-on weight limits.
- Buying the biggest bag allowed, then overpacking it until it no longer fits the sizer.
- Forgetting the personal item. A small backpack under the seat adds a lot of capacity.
FAQ
What size is a carry-on bag?
Many US airlines, including American and Delta, set a maximum of 22 x 14 x 9 inches (56 x 36 x 23 cm) including wheels and handles. Limits differ between airlines and fare types, so check your airline before you fly.
Is a hardside or softside carry-on better?
Neither is better for everyone. Hardside protects contents and handles rain; softside is usually lighter and more flexible with outside pockets.
Should I get a backpack instead?
If you’ll walk a lot, take stairs or travel over rough streets, a travel backpack can be easier. See travel backpack vs suitcase and our travel backpack guide.
Final recommendation
If you fly airlines that weigh bags, start with the Travelpro Maxlite 5 Compact. If you want a protective shell and extras, the Platinum Elite Compact Hardside is the more feature-rich choice, at the cost of weight. Once you’ve chosen, read how to pack a carry-on to make the most of it.
