Qatar allows a cabin bag of 50 × 37 × 25 cm — 19.7 × 14.6 × 9.8 inches — and weighs it at 7 kg (15.4 lb), which most US carriers never do. Qatar publishes no personal item dimensions.

The one most likely to catch you out. At 50 cm the length limit is 19.7 inches — a standard American 22-inch spinner is more than two inches too long, and the generous width and depth disguise it. Qatar also warns that a separately carried laptop bag counts as your carry-on rather than an extra. On flights departing the US it applies the usual bag-plus-personal-item pattern.
Measure the outside, wheels and handles included — that’s what they measure at the gate.

That is not a gap in the list — at 50 cm the longest side is 19.7 inches, and effectively every bag sold as a carry-on in the US is built to 22 inches. If you are flying Qatar, you need a genuinely smaller case, or you check it.
50 × 37 × 25 cm, which is 19.7 × 14.6 × 9.8 inches, up to 7 kg (15.4 lb).
Qatar publishes no dimensions for a personal item. A small bag is described but not measured, so there is no number to check against.
No — it is 2.3 inches over. Qatar allows 19.7 × 14.6 × 9.8 inches, and the standard US 22 × 14 × 9 does not fit inside that.

Of the bags we track, 0 of 16 carry-ons fit the cabin limit. All of them are under the weight limit empty.
Manufacturers publish dimensions inconsistently, and a “20-inch” spinner is almost never 20 inches once you count the wheels. Where a brand states dimensions including wheels and handles, that’s the number we use. Where it only publishes the case, we say so on the card. Airlines measure the outside of your bag — wheels, handles, straps and all. Anything marked borderline is down to the gate agent, and remember that a soft bag squashes into a sizer while a hard shell won’t.
