Luggage Size Guide
Voyage buying guide
Find the right luggage size for the way you travel.
Start with your airline, trip, packing style, and how much you want to carry. Then measure the bag itself—including wheels, handles, and any expanded depth.

A practical place to start
These are common retail size bands, not airline approvals. Exterior measurements and usable capacity vary by model, so always check the product specifications and your carrier’s current rules.
Need maximum capacity? Explore extra-large luggage, but compare the bag’s packed linear dimensions and weight with your airline’s checked-baggage limits before departure.
Measure correctly
Use the bag’s true outside dimensions
Airlines evaluate the complete packed bag—not only the shell or fabric body.
-
Pack it as you plan to travel
Close every compartment. If you intend to use the expansion zipper, measure the bag expanded.
-
Measure the tallest point
Stand the bag upright and include wheels, fixed feet, and the collapsed top handle.
-
Measure the widest point
Include side handles, pockets, frame edges, and anything else that projects beyond the body.
-
Measure the deepest point
Measure front to back, including packed exterior pockets and expanded sections.
-
Add all three measurements for linear size
Checked-baggage rules often use a combined linear measurement, while carry-on rules usually specify a maximum for each side.
Compare sizes
Match the bag to the trip—not just the trip length
Climate, footwear, formal clothing, gifts, laundry access, and whether you share a bag can change what you need more than the number of days alone.
| Category | Common outside height | Often suits | Check before choosing |
|---|---|---|---|
| Underseat luggage | Varies widely | Essentials, short trips, or pairing with a larger bag | Your airline’s personal-item limit and the aircraft’s underseat space |
| Carry-on luggage | About 20–22 in | Travelers who want to avoid checking a bag when their fare allows | Every exterior dimension, fare allowance, weight rule, and operating carrier |
| Medium checked luggage | About 23–26 in | Versatile checked packing without jumping to the largest footprint | Packed weight and linear dimensions |
| Large checked luggage | About 27–30 in | Longer trips, bulkier clothing, or shared packing | How quickly the larger volume can exceed weight limits |
| Extra-large luggage | About 30 in and above | Special packing needs where capacity matters most | Oversize thresholds, handling, storage, and vehicle fit |
Before you fly
“Carry-on size” is not a universal approval
Airlines set their own dimensions, weight limits, fare allowances, and enforcement rules. Partner-operated and regional flights can also have less cabin space, and a compliant bag can still be gate-checked when bins fill.

Smart luggage reminder: Power banks and spare lithium batteries belong in carry-on baggage. If a carry-on is gate-checked, remove them and keep them in the cabin, following current FAA and airline requirements.
Common questions
Luggage sizing FAQ
Do wheels and handles count in luggage measurements?
Yes. Measure the entire exterior of the packed bag, including wheels, fixed feet, handles, pockets, and any expanded depth.
Is every 22-inch suitcase accepted as a carry-on?
No. Height is only one measurement. Width, depth, wheels, handles, packed expansion, airline rules, fare type, and aircraft space all matter.
What does 62 linear inches mean?
It means the bag’s exterior height, width, and depth add up to 62 inches. Many U.S. carriers use 62 linear inches as a standard checked-bag threshold, but the carrier’s current policy controls.
Should I buy an expandable suitcase?
Expansion adds flexibility, but it also increases depth and encourages heavier packing. Measure and weigh the bag in the configuration you will take to the airport.
Should I choose one large bag or a luggage set?
A set gives you more size options across different trips. A single bag can be simpler when you already know your usual packing volume. Compare storage space, packed weight, and the sizes you will actually use.
