Bag Size Checker: Will Your Bag Fit as Cabin Baggage?
✓ Checked: July 2026 against each airline's published cabin baggage rules · Limits move without notice, so confirm on your ticket
✈️ Cabin Baggage Size Checker (14 Airlines)
Tape the packed bag first: wheels, handles and any bulging pocket go into the numbers. Weight is optional.
Order never matters: the tool arranges your three numbers from longest to shortest and holds them against each airline's frame arranged the same way, which is how a real bag meets a real sizer. Data sources and dates: how we verify.
The exact limits this checker tests
These are the numbers the tool compares against, taken from each airline's published cabin baggage rules and checked in July 2026. Each airline name links to its full guide with checked allowances and fees.
| Airline | Cabin bag limit (cm) | Weight |
|---|---|---|
| IndiGo | 55 × 35 × 25 | 7 kg |
| Air India | 55 × 40 × 20 | 7 kg |
| Air India Express | 55 × 35 × 25 | 7 kg |
| SpiceJet | 55 × 35 × 25 | 7 kg |
| Akasa Air | 55 × 35 × 25 | 7 kg |
| Emirates | 55 × 38 × 22 | 7 kg |
| Etihad | 56 × 36 × 23 | 7 kg |
| Qatar Airways | 50 × 37 × 25 | 7 kg |
| Saudia | 56 × 45 × 25 | 7 kg |
| flynas | 56 × 36 × 23 | 7 kg |
| flydubai | 55 × 38 × 20 | 7 kg |
| Oman Air | 51 × 41 × 23* | 7 kg |
| Kuwait Airways | 56 × 46 × 25 | 7 kg |
| Gulf Air | 45 × 40 × 30 | 6 kg |
*Oman Air publishes a 115 cm total across the three sides. Some of its pages quote per-side caps of 51 × 41 × 24 cm, which add up to 116 cm, so this checker holds the last side at 23 cm and both versions of the rule stay satisfied. Economy figures on standard fares; premium cabins differ.
How to measure your bag before you type anything
Stand the bag upright, packed the way it will fly, and run a steel tape over its three outside spans. Height goes from the floor to the highest point of the closed carry handle. Width crosses the broadest face, side handles included. Depth runs from the back panel to the front pocket at its fullest bulge.
Three habits keep the numbers honest:
- Pack first, measure second. Soft panels swell by 2 to 4 cm once clothes press against them, so an empty measurement flatters the bag.
- Close the expander zip. Airlines judge the bag that arrives at the gate, and an open expander adds 4 to 5 cm of depth on most trolleys.
- Count every attachment. Wheel housings, feet, the handle stub on top and a stuffed side pocket all sit inside the frame with the bag.
Then enter the three numbers above in any order. The tool sorts them before comparing, so calling a side "length" or "height" changes nothing.
Why the same bag passes one airline and fails another
All 14 airlines allow a broadly similar amount of cabin luggage. They draw different boxes around it, though, and your bag is one fixed shape. That mismatch of shape against shape produces most gate surprises on this corridor.
Four frames cause the bulk of them:
- Qatar Airways trims the long side to 50 cm. Every 55 cm trolley that Indian carriers accept lands in Doha 5 cm too long for the frame.
- Gulf Air runs the smallest long side of all at 45 cm, plus the only 6 kg weight cap on this list. Its frame is 30 cm deep, though, so a squat daypack can pass Gulf Air and fail airlines that look more generous.
- Emirates against flydubai is a 2 cm story. Both publish 55 by 38 cm, then Emirates allows 22 cm of depth and flydubai only 20 cm. A soft bag packed round fails one Dubai carrier and passes the other.
- Oman Air states a 115 cm total across the three sides. Its per-side caps appear as 51 × 41 × 24 cm in places, which adds up to 116 cm, so this checker holds the last side at 23 cm; that way the per-side caps and the 115 cm total are both respected. If your bag lives on that edge, confirm on your ticket.
The arithmetic of overlap is stark. A bag inside 45 × 35 × 20 cm and 6 kg clears the whole board. The classic Indian 55 × 35 × 25 trolley clears exactly six: IndiGo, Air India Express, SpiceJet, Akasa Air, Saudia and Kuwait Airways. Air India misses that list because of its slim 20 cm third side, the same figure that trips overpacked bags on flydubai.
Soft shell or hard shell at the sizer frame
Gulf boarding gates use metal sizer frames, and the two shell types behave differently inside them. A soft bag taped at 57 cm can often be pressed into a 55 cm frame if it still has give; wheels and the handle housing are the only parts that refuse to compress. A hard shell taped at 57 cm stays 57 cm, and the frame wins.
That flexibility cuts both ways. The soft bag's give is also how it drifts over the limit in the first place: stuff it round and the depth grows past 20 cm without you noticing. A hard shell holds the size printed on its tag, packed full or half empty.
If you fly Gulf routes on full flights, the calmer combination is a hard shell bought 2 cm inside the strictest frame you use, or a soft bag packed with room left to squeeze.
When your bag fails: four fixes that work
The grid above names the airline and the rule, so you know whether the problem is centimetres or kilos before you spend anything.
- Repack flat. Soft bags fail on depth more than length. Shoes along the spine, nothing round against the front panel, expander closed. A 1 to 2 cm overage on a soft bag often vanishes here.
- Prebook a checked bag. If the overflow is real, buying hold luggage online before departure usually costs around half of the airport counter rate. Price your route in the excess baggage calculator before you decide.
- Wear the heavy things. The jacket goes on you, the boots go on your feet, the power bank rides in a pocket. Scales weigh bags, not passengers.
- Load the personal item. Most airlines here allow a small under-seat bag besides the main one, so dense items such as chargers and books can move there. SpiceJet folds that item into the same 7 kg, so the trick does nothing on SpiceJet; check your airline's rule.
The one move that never pays is arriving at the gate and hoping. Gate-rate fees sit at the top of every fee table, and the sizer frame does not negotiate.
The American 22 × 14 × 9 inch standard vs the Indian 55 × 35 × 25
A large share of luggage sold online follows the American carry-on standard of 22 × 14 × 9 inches, which converts to 55.9 × 35.6 × 22.9 cm. Bags built for the Indian market follow 55 × 35 × 25 cm instead. The two differ by less than a centimetre on two sides, and that sliver decides real verdicts.
Run both through the tool and the split is clean. The American shape passes four airlines here: Etihad, flynas, Saudia and Kuwait Airways; Etihad and flynas wrote their 56 × 36 × 23 cm rule around that very standard. On the Indian low-cost carriers it sits 9 mm over the 55 cm length, a fraction that a strict frame can still refuse.
The Indian shape has the opposite problem. Its 25 cm depth is legal at home and 2 to 5 cm too deep for Emirates, Etihad, flynas and flydubai.
Buying one bag for both worlds? Stay inside 50 × 35 × 20 cm and 13 of the 14 frames here turn green, with Gulf Air's 45 cm frame the lone holdout. Drop the long side to 45 cm and the whole board passes.
FAQs: bag size checker
How do I measure my bag for this checker?
With a tape on the packed bag: floor to handle top with the handle down, across the widest face, and back panel to the fattest point of the front pocket. Wheels, handles and bulging pockets all count, because the airline's sizer frame counts them. Manufacturer labels usually quote the shell alone, which runs 2 to 3 cm small.
Why does my bag pass IndiGo but fail Qatar Airways or Gulf Air?
Frames differ by shape. Indian carriers accept 55 cm on the long side, Qatar Airways stops at 50 cm and Gulf Air at 45 cm, so the same trolley reads as fine in Delhi and oversize in Doha or Bahrain. Gulf Air also caps cabin weight at 6 kg instead of the usual 7 kg.
Does a 22 × 14 × 9 inch American carry-on work on Indian airlines?
On paper, no. It converts to 55.9 × 35.6 × 22.9 cm, which is 9 mm over the 55 cm length used by IndiGo, Air India Express, SpiceJet and Akasa Air. It does pass Etihad, flynas, Saudia and Kuwait Airways. The margin is small enough that enforcement varies, so confirm on your ticket and pack for the strictest frame of your trip.
What should I do if my bag fails the check?
Three fixes, in order of cost: repack so the soft sides sit flat and the depth drops; move the overflow into a prebooked checked bag, which usually costs around half the airport counter rate; or wear the heaviest items and shift dense gear into your under-seat personal item where the airline permits one.
Does the order I enter length, width and height matter?
No. The tool sorts your three numbers from longest to shortest and compares them with each airline's frame sorted the same way, since a bag can enter a sizer frame in any orientation. Type the three outside measurements in any order and add the weight if you know it.
