Size and weight questions are the single biggest hand carry topic in Pakistan — bigger than prices, bigger than brands. That makes sense: a bag that is 3 cm too deep or 1 kg too heavy can be taken off you at the gate and charged as checked baggage. This page gives you the numbers, the reasoning behind them, and a measuring method that works for any bag you already own.
Measure height, width and depth — including wheels and handles — before you trust any size printed on a shopping listing.
The standard cabin size, explained
The figure you will see again and again for flights from Pakistan is 55 x 40 x 20 cm, roughly 22 x 16 x 8 inches, with a weight limit of 7 kg. It is the size widely reported for PIA, and it is very close to the official figures of Pakistan's other carriers: SereneAir and AirSial both publish a total-dimension limit of 45 inches (length + width + height added together) and a 7 kg weight cap. A 55 x 40 x 20 cm bag adds up to 115 cm, or about 45.3 inches — right at that line, which is why soft bags that can squeeze slightly are safer than hard shells at the maximum size.
Why 20 cm deep? Cabin bags live in overhead lockers or under seats, and locker depth is the tightest constraint on most aircraft. A bag can be a little tall or a little wide and still fit diagonally; a bag that is too deep simply will not let the locker door close. That is why gate staff check depth first, and why trolley bags with protruding wheels get rejected even when the body of the bag measures fine — wheels and handles count in the measurement.
The 7 kg weight rule
Seven kilograms is the standard economy hand carry weight on routes from Pakistan. PIA's widely reported limit is 7 kg; SereneAir states 7 kg total hand carry on its official site and does not count a laptop in that weight; AirSial's ticket information also sets hand baggage at a maximum of 7 kg. The Gulf carriers agree: Emirates economy cabin baggage is 7 kg, Qatar Airways economy hand baggage is 7 kg, and Etihad's hand-baggage-only fare allows a 7 kg cabin bag plus a separate 5 kg personal item.
Here is the part most buyers miss: the 7 kg includes the bag itself. A hard-shell trolley can weigh 2.8 to 3.5 kg empty, leaving you barely 4 kg for clothes and everything else. A soft duffel or fabric cabin bag often weighs 0.8 to 1.5 kg empty, which nearly doubles your usable packing weight. When you shop, the empty weight of the bag matters as much as its size — our 7 kg hand carry guide is built entirely around this trade-off.
Weigh the packed bag at home. A cheap luggage scale costs less than one excess-baggage charge.
Official limits for the airlines Pakistanis fly most
The table below separates what airlines publish officially from what is widely reported. Figures marked "official" were published by the airline and verified on October 30, 2026 for our sister baggage database. The full detail for each airline — fare differences, personal items, what to do when no official figure exists — is on its own page.
| Airline | Cabin bag size | Weight | Source |
|---|---|---|---|
| PIA | 55 x 40 x 20 cm (reported) | 7 kg | Widely reported; confirm on ticket |
| SereneAir | 45 inches total (L+W+H) | 7 kg, laptop excluded | Official |
| AirSial | 22 + 15 + 8 inches (45 total) | 7 kg | Official ticket information |
| Emirates | 55 x 38 x 22 cm | 7 kg Economy | Official |
| Qatar Airways | 50 x 37 x 25 cm | 7 kg Economy | Official |
| Etihad | 56 x 36 x 23 cm (hand-baggage fare) | 7 kg + 5 kg personal item | Official, that fare |
| Airblue | Not published in a readable official figure | Check your fare | How-to-check guide |
| Fly Jinnah | Set by fare bundle | Check your fare | How-to-check guide |
| Turkish Airlines | Given by the airline's baggage calculator | By route and fare | How-to-check guide |
Notice the pattern: sizes cluster tightly around 55 cm tall and 7 kg, but the depth and the exact shape differ. A bag bought to the largest limit (Emirates' 22 cm depth, Etihad's 56 cm height) can fail on a stricter airline (Qatar's 50 cm height). If you fly several airlines, buy for the strictest one you use regularly — for most people that means a bag at or under 55 x 40 x 20 cm.
How to measure your bag correctly
- Empty the bag completely and zip every expansion section closed — expanded bags are measured expanded if you board with them open.
- Height: stand the bag on its wheels and measure from the floor to the top of the shell, not the extended trolley handle.
- Width and depth: measure the widest points, including side pockets, compression straps and protruding wheels.
- Add the three numbers if your airline uses a total (linear) limit like SereneAir's and AirSial's 45 inches.
- Weigh it packed on a bathroom scale: weigh yourself holding the bag, then without, and subtract. Stay at least half a kilo under the limit — airport scales and yours rarely agree exactly.
Inches, centimetres and the "20-inch bag" trap
Pakistani shopping listings describe cabin suitcases as "20-inch" bags. That number is the height of the case body in a product family (20, 24, 28 inch), not a measurement you can compare directly with an airline's centimetre limit — and it usually excludes wheels. A typical 20-inch cabin suitcase measures about 55 x 35 x 20 cm including wheels, which fits the common standard; but some "20-inch" models are 58 cm tall with wheels and will fail a strict sizer. Always convert the listing's full external dimensions to centimetres and compare all three numbers, not the headline size. Our cabin bag vs hand carry explainer clears up the naming confusion, and the airline size comparison puts every verified figure side by side.
At the gate, your bag goes into a metal sizer frame. If it does not drop in freely, it does not fly as hand carry.
What happens if your bag is too big or too heavy
Outcomes vary by airline and airport, but the usual sequence is: the bag is tagged and moved to the hold, and you pay the checked-baggage or excess rate for your fare — which at the airport is almost always higher than buying allowance in advance. On full flights, gate staff may also collect cabin bags for free hold carriage, starting with the largest ones. Fragile items, medicines, documents, laptops and power banks must come out before a bag is gate-checked, because batteries are not allowed in the hold at all. Packing with that moment in mind is covered in how to pack a hand carry bag.
Personal items: the second, smaller bag
Most allowances separate the cabin bag from a smaller personal item — a handbag, small purse, laptop bag or small briefcase that fits under the seat in front of you. Qatar Airways lists a small purse or briefcase explicitly; Etihad's hand-baggage fare gives the personal item its own 5 kg and 23 x 39 x 19 cm limits. Pakistani domestic carriers describe hand carry as a single total in most published material, which is why the two bags question and the ladies handbag question deserve their own careful answers.
