The right carry-on luggage size fits your airline's current cabin limits with wheels and handles included. Measure the bag at its widest points, because a suitcase named 20 or 22 inches can have a larger outside size.
Use 22 x 14 x 9 in as a comparison point, not a promise of acceptance. Check your airline's rules for your route, then compare them with the bag's full dimensions.
What carry-on luggage size fits most airlines?
No single carry-on size guarantees a fit across airlines. Start with your airline's current limit before you choose a suitcase or pack for a trip.
A suitcase's named size can refer to its case alone rather than its outer dimensions. Wheels, handles and other parts can add to the overall measurements, so use complete exterior measurements when comparing bags.
A few examples show why the model name alone isn't enough:
- The Samsonite Freeform 21-Inch Carry-On has a 20.5 x 14.5 x 10 in interior, which isn't the measurement to use for cabin fit.
- The American Tourister Stratum 2.0 Carry-On measures 22 x 15 x 9.5 in, though you should confirm whether that measurement includes every projecting part.
- The Travelpro Maxlite Air V2 20-Inch Carry-On measures 23 x 14.5 x 9.5 in overall, including wheels and handles.
- The Samsonite Omni 2 Domestic 22-Inch Carry-On has conflicting exterior measurements, so its name alone doesn't settle cabin fit.
Samsonite's exterior measurements also conflict for the Freeform, so confirm the full outside dimensions of both Samsonite models before ordering. Compare each dimension with your airline's maximum rather than relying on a carry-on label.
How do you measure carry-on luggage?
Measure the full outside of your packed suitcase, including wheels and handles. Check height, width and depth at their widest points, then compare each measurement with your airline's limit.
- Stand the bag upright on a flat surface.
- Measure from the floor to the highest point with the telescoping handle retracted.
- Include the wheels and any fixed handles that stick out.
- Measure the widest part across the front and the deepest part from front to back.
- Compare all 3 measurements with your airline's cabin bag rules.
Measure an expandable bag while it is expanded if you plan to use the expansion zipper. The American Tourister Stratum 2.0 Carry-On expands by 1 in, and the Travelpro Maxlite Air V2 20-Inch Carry-On expands by 2 in.
If you want a broader comparison of cabin, medium and large suitcases, see standard luggage sizes.
Do wheels and handles count toward carry-on size?
Include wheels and handles when the airline defines its limit using total outer dimensions. Follow any specific measuring instructions the airline provides.
A suitcase named 21 inches may be taller once its wheels and fixed top handle are included. Check the actual outside dimensions and make sure they use the same measurement method as your airline.
The Travelpro Maxlite Air V2 20-Inch Carry-On illustrates the difference: its case is 19.75 in high, but its overall height is 23 in. Use the overall measurement for a limit that includes wheels and handles.
Are carry-on size limits the same on every airline?
Airlines set their own carry-on limits, so check every carrier on your itinerary. Don't assume the bag that fits your first flight will meet the rules for a connection.
Use the airline's official site or travel documents to find its current cabin bag size. For example, American Airlines' carry-on baggage guide is a place to check its requirements before packing.
The complete carry-on luggage guide covers how to choose a bag alongside size. For weight rules, see carry-on luggage weight limits.
What if your carry-on is slightly too large?
A bag that exceeds the airline's limit may need to be checked. Choose a suitcase that fits with some margin instead of counting on an exception at the airport.
Don't rely on squeezing a bag into shape to make it acceptable. Expansion adds depth, so a suitcase that fits when closed may exceed the limit with its expansion zipper open.
For a close fit, measure again after packing. Put bulky items inside, close all zippers and check the suitcase as you'll carry it.
How much does a carry-on suitcase weigh?
Empty suitcase weight varies by model, and your airline may also limit the packed bag's weight. Check both size and weight requirements before your flight.
The Samsonite Freeform 21-Inch Carry-On weighs 6.5 lb, the American Tourister Stratum 2.0 Carry-On weighs 7.3 lb, and the Travelpro Maxlite Air V2 20-Inch Carry-On weighs 6.7 lb. A lighter empty bag leaves more of a fixed weight allowance for your belongings.
Weigh the packed suitcase with everything you plan to leave inside it. For tips on making room without overpacking, read how to pack a carry-on suitcase.
Which carry-on suitcase size should you choose?
Choose a bag whose full exterior measurements fit the strictest limit on your itinerary. If you're comparing bags with similar dimensions, also consider expansion, empty weight and interior organization.
Compare carry-on luggage size and packing features
Check cabin fit first, then choose the packing features you'll use. Straps, divider panels and pockets can help organize your belongings, but they don't change the airline's size allowance.
Check the airline's carry-on size before you go
Choose your carry-on luggage size using the strictest airline limit on your route. Measure with wheels and handles included, and leave some margin if you plan to use expansion.
Pick the Freeform for its straps, divider and pouch, or the Travelpro for its 2 zippered divider panels, once you've confirmed cabin fit. If you're still deciding what to buy, compare our carry-on luggage picks.
Frequently asked questions
What is the standard carry-on luggage size?
There isn't one size that every airline accepts. Use 22 x 14 x 9 in as a comparison point, then check your airline's actual limit.
Compare the suitcase's full exterior dimensions, including wheels and handles, with the rules for every flight on your route.
Do carry-on dimensions include wheels and handles?
Use wheels and handles when comparing a bag with an airline's total exterior size limit. Measure from the floor to the highest point and across the widest parts, including anything that sticks out.
Follow your airline's measuring instructions if it gives a specific method.
Is a 22-inch suitcase a carry-on?
It can be, but the number in a suitcase's name may not match its full exterior height. Measure the height with wheels and handles included, then compare all 3 outside dimensions with your airline's current limit for your route before you travel.
Do international airlines have smaller carry-on limits?
International travel doesn't come with one shared carry-on size limit. Check each airline on your itinerary rather than assuming a bag accepted on one flight will fit another.
Include connecting flights in that check, and review any separate weight limit before you pack.
