Understanding carry-on luggage size can feel confusing, especially with different rules across airlines. Whether you’re flying within India or travelling abroad, knowing the right cabin bag size helps you avoid last-minute stress, repacking at the gate, and extra fees. This guide explains everything you need to know before your next trip.
What Is a Carry-On Bag?
A carry-on bag is luggage you’re allowed to take inside the aircraft cabin. It usually goes in the overhead bin, while smaller items like a laptop bag or handbag stay under the seat in front of you.
If your bag is larger than the airline’s carry-on allowance, it must be checked in.
Carry-On vs. Personal Item
Carry-On Bag:
A small trolley suitcase, duffel, or travel backpack that fits overhead.
Personal Item:
A laptop bag, handbag, sling, or compact backpack that fits under the seat.
Checked-In Bag:
Large suitcases that go into the aircraft’s cargo hold.
Understanding these categories helps you pack correctly and avoid surprises at the airport.
Standard Carry-On Size
The most widely accepted international carry-on size is:
22" x 14" x 9" (56 x 36 x 23 cm)
This includes wheels, handles, and any protruding pockets.
Weight Limit:
Usually 7 kg for Indian airlines
7–10 kg for most international airlines
Some premium cabins may allow more.
Always check your airline’s policy before travelling, as rules can change.

To avoid issues, measure your luggage fully packed.
Tips for Choosing the Right Carry-On
Hard-Shell or Soft-Shell?
Hard-shell luggage offers better protection and a premium finish, while soft-shell bags provide extra pockets and more flexibility.
Look for Smooth Wheels
Spinner wheels make airport navigation easier.
Expandable Bags — Use Caution
Expandable carry-ons are convenient, but expanding them may push the size beyond airline limits.
Internal Organisation Matters
Look for compression straps, mesh dividers, laptop sleeves, and quick-access pockets.
Can a Backpack Be a Carry-On?
Yes.
Many travel backpacks (30–45L) are designed to meet cabin size requirements. Just ensure the bag fits within the airline’s limits and isn’t overstuffed.
Popular Carry-On Options to Consider
Some popular categories suited for most travellers include:
-
Lightweight polycarbonate cabin suitcases

Compact soft-side cabin bags

Travel backpacks built for overhead storage
