There is no such thing as "the Indian cabin bag size." Five carriers publish five different limits. A bag that clears IndiGo's sizer can be refused at an Air India gate, on a dimension most people never check.
The number almost every blog repeats — 55 × 35 × 25 cm — is IndiGo's and SpiceJet's. Air India's is 55 × 40 × 20 cm. Air India Express publishes 56 × 36 × 23 cm. Akasa publishes no per-side limit at all. Those are not rounding differences; they are different shapes, and depth is where they diverge most.
Every figure below comes from each airline's own policy page, read on 5 August 2026. None of it comes from other summaries. Where an airline's wording is odd, we say so rather than smooth it over.
Every Indian airline's cabin limit, side by side
| Airline | Max dimensions (cm) | L+W+H | Cabin bag weight | Personal item |
|---|---|---|---|---|
| IndiGo | 55 × 35 × 25 | ≤ 115 | 7 kg | 3 kg, separate |
| Air India — Economy & Premium Economy | 55 × 40 × 20 | ≤ 115 | 7 kg | 3 kg, separate |
| Air India — Business & First | 55 × 40 × 20 | ≤ 115 | 10 kg | 3 kg, separate |
| Air India Express | 56 × 36 × 23 | not stated | 7 kg total for both pieces | 40 × 30 × 10, inside the 7 kg |
| SpiceJet — Boeing 737 | 55 × 35 × 25 | 115 | 7 kg total for both pieces | laptop bag or purse, inside the 7 kg |
| SpiceJet — Q400 turboprop | 50 × 35 × 23 | 108 | 7 kg total for both pieces | laptop bag or purse, inside the 7 kg |
| Akasa Air | no per-side limit published | ≤ 115 | 7 kg | 3 kg, separate |

Three things in that table are worth pulling out, because they are where people actually get caught.
Air India's depth limit is 20 cm. Every other carrier allows 23 to 25 cm. This is the single tightest dimension in Indian domestic flying and the one that almost no cabin trolley sold here respects.
SpiceJet's Q400 is stricter than its Boeings. These turboprops fly short routes such as Dehradun, Jabalpur and Kandla. They take 50 × 35 × 23 cm, not 55 × 35 × 25 cm. Your bag can be legal on the outbound 737 and too big on the return Q400.
Akasa gives only a total. 7 kg, and 115 cm added up, with no side limit given. So by that rule, a 60 × 35 × 20 cm bag is fine on Akasa and too big everywhere else.
The 20 cm problem
Air India allows 55 cm of height and a generous 40 cm of width, then caps depth at 20 cm. Cabin trolleys are not built to that.
A typical four-wheel hardshell cabin case measures 23 to 25 cm front to back once the wheels are counted. Mokobara's Transit Cabin Pro, to take a model whose maker publishes real external figures, is 56 × 34.5 × 24 cm. Against the published limits, that bag is 1 cm too long for IndiGo. It is 4 cm too deep for Air India, and 1 cm too deep for Air India Express. It is within Akasa's 115 cm total.
That is not a knock on one brand. It is the shape of the whole category. Wheeled hardshell cabin luggage is built around a 55 × 35 × 23-25 cm envelope. That is the IndiGo and SpiceJet Boeing spec. Air India's 20 cm is a different envelope, and the market does not build for it.
What this means in practice: if you fly Air India in economy with a wheeled hardshell case, you are almost certainly over the published depth.
Enforcement is patchy. Gate checks in India are driven far more by weight, and by how full the bins are, than by a depth measurement. But the rule is the rule, and it is the airline's call on the day. A soft-sided bag has the edge here, because it squashes. A hardshell cannot.
Your bag's listed size is not its real size
This is the trap underneath everything above.
"55 cm" on a product listing is a size class, not a measurement. It describes roughly how tall the case body is. It tells you nothing about the two dimensions airlines also measure, and it usually excludes the parts that stick out.
Airlines measure the bag as an object, not the shell. IndiGo states it outright: "This dimension includes handles and wheels." Air India Express goes further — its limit is "including the handles, wheels, and side pockets." Airport sizers are boxes. A bag either drops in or it does not, and the wheels go in with it.
Take a case whose shell is 55 cm tall, with 3 cm wheels and a 2 cm handle housing. That is a 55 cm bag on the listing. It is a 58-60 cm bag at the sizer.
How to measure yours properly. Stand the bag upright on the floor, packed the way you actually travel, and measure the outside of everything:
- Height — floor to the highest fixed point, including the retracted handle housing and the wheels the bag is standing on.
- Width — the widest point, including side handles and any bulge from a packed front pocket.
- Depth — front to back at the fattest point, including wheels that stick out and an opened expansion zip.
Then check that number against the airlines you actually fly, not against the listing.
If your bag has an expansion zip, measure it both ways. An expanded case gains 3 to 5 cm of depth. That is enough to move it from legal to oversized on every carrier in the table.
The one size that clears everything
Take the smallest published value on each axis, across all seven rows above. That gives you the envelope that clears every Indian carrier, on every aircraft type:
50 × 35 × 20 cm, measured over wheels and handles.
That is driven by SpiceJet's Q400 on length, IndiGo and SpiceJet on width, and Air India on depth. If you never fly SpiceJet's turboprops, the practical target relaxes to:
55 × 35 × 20 cm.
Both totals sit well under the 115 cm and 108 cm sum limits. So a bag inside either envelope clears every rule on this page — the per-side limits and the sums.
Almost nothing wheeled is sold at 20 cm deep. The bags that hit this envelope are cabin backpacks, soft holdalls and the slimmer two-wheel soft cases.
A smaller wheeled case gets you closer without getting you there. An overnighter trolley is 38-48 cm tall, so it clears every length limit on this page with room to spare. Depth is still the problem. A typical 42 cm case is 22-24 cm front to back, which is over on Air India. One 45 cm case in that shortlist adds up to 117 cm, and a buyer was refused by three carriers.
That is the real trade-off. A wheeled hardshell is easier through a terminal and protects better. It is also the format most likely to be over on depth. A 40-45 L cabin backpack clears every carrier. If you fly mixed carriers and want to stop thinking about this, that is the one to buy.
The personal item is not the same allowance everywhere
This is the difference that costs people money, and it splits the market cleanly in two.
IndiGo, Air India and Akasa give you a personal item on top. One additional article — a purse, or a small bag with a laptop — up to 3 kg, over and above the 7 kg cabin bag. Effective allowance: 10 kg.
SpiceJet and Air India Express count it inside. You may carry two pieces, but their combined weight must not exceed 7 kg. A laptop bag with a 15-inch laptop, charger and a book runs 3 to 4 kg. That leaves you barely 3 kg for the cabin bag itself. Effective allowance: 7 kg.
Same 7 kg headline, very different allowance. If you often fly hand-baggage-only with a laptop, that gap is the difference between packing in peace and repacking at the gate.
Air India Express also caps the personal item at 40 × 30 × 10 cm. That is slimmer than many laptop bags, once a charger is in the front pocket.
Weight is what actually gets enforced
Every carrier in the table sets 7 kg for economy cabin baggage. That is the limit that gets checked. Weighing a bag takes two seconds; measuring one takes a conversation.
The maths is unforgiving. An empty 55 cm hardshell cabin case weighs 2.5 to 3.5 kg. On a 7 kg allowance, the bag itself is a third to a half of what you are allowed before anything goes in it. A 40-45 L cabin backpack weighs 0.9 to 1.5 kg and gives you 5.5 kg of packing weight instead of 3.5 kg.
Fly hand-baggage-only with any regularity, and the empty weight of the bag is the spec that matters most. It counts for more than the shell, the wheels or the brand.
Going over is priced. SpiceJet charges ₹750 per kg at the gate, for up to 5 kg of excess, to a cabin cap of 12 kg. Air India charges ₹3,000 at home and USD 75 abroad when a cabin bag is over on weight or size.
Air India Express sells the overage up front instead. You buy a 3 kg or 5 kg "Xtra carry-on" block, up to 12 kg in total. Booked ahead, it is far cheaper than paid at the gate.
Common mistakes to avoid
Trusting the "cabin size" label. Brands sell cases as cabin luggage against the loosest common limit, not the tightest. A bag can be marketed as cabin-compliant and be over Air India's depth by 4 cm. The label is a marketing category, not a certification.
Measuring the shell instead of the bag. Wheels, handle housing and side pockets all count. This is where most of the surprise comes from, and it is worth 4 to 6 cm.
Assuming one airline's rule covers the trip. Codeshares, connections and mixed-carrier returns are common on Indian routes. The strictest airline on the ticket is the one that counts. IndiGo tells you to check your booking email for the allowance on a codeshare.
Packing to the size limit and ignoring the weight limit. A bag that fits the sizer at 9 kg still gets stopped. Weight is checked far more often than dimensions.
Expanding the case on the return leg. The expansion zip turns an outbound-legal bag into an inbound-oversized one. It is also the most common point of failure on cabin cases.

What is the cabin baggage size limit for Indian airlines?
There is no single limit. IndiGo and SpiceJet's Boeing fleet allow 55 × 35 × 25 cm. Air India allows 55 × 40 × 20 cm. Air India Express allows 56 × 36 × 23 cm. SpiceJet's Q400 turboprops allow 50 × 35 × 23 cm. Akasa gives only a 115 cm total, with no per-side limit. Every carrier sets 7 kg for economy. A bag of 50 × 35 × 20 cm over its wheels and handles clears all of them.
Do cabin bag dimensions include the wheels and handle?
Yes. IndiGo's policy says the dimensions include handles and wheels. Air India Express names handles, wheels and side pockets. Airport sizers are fixed boxes, so anything that sticks out counts. A case listed as 55 cm usually measures 58-60 cm, once wheels and the handle housing go in.
Why does my cabin bag pass on IndiGo but not Air India?
Depth. IndiGo allows 25 cm front to back; Air India allows 20 cm. Most wheeled hardshell cabin cases are 23-25 cm deep. So they clear IndiGo easily and sit 3-5 cm over Air India. Air India is kinder on width, at 40 cm against IndiGo's 35 cm. The two limits are different shapes, not one simply bigger than the other.
How strictly is the 7 kg cabin weight limit enforced in India?
Weight is checked far more often than size, because weighing is quick and measuring is not. Gate-side weighing is routine on the low-cost carriers. SpiceJet charges ₹750 per kg at the gate, up to a 12 kg cabin maximum. Air India charges ₹3,000 on domestic sectors. Going over is priced, not waved through.
Can I carry a laptop bag in addition to my cabin bag?
On IndiGo, Air India and Akasa, yes — one personal item up to 3 kg, on top of the 7 kg cabin bag. On SpiceJet and Air India Express you may carry two pieces, but together they must not top 7 kg. A laptop bag eats straight into the cabin bag's allowance. Air India Express also caps the personal item at 40 × 30 × 10 cm.
