13.5 × 8.5 × 3.75 inEnormous margin against every limit here, and it looks like a normal bag rather than travel gear. Ten litres is a daybag though, not a travel bag.
Air Canada allows a cabin bag of 55 × 40 × 23 cm — 21.5 × 15.5 × 9 inches, with no published weight limit. The under-seat item is 43 × 33 × 16 cm.
Fare class: Economy Basic tickets bought on or after 3 January 2025 are personal item only on selected North America and Caribbean routes.
Air Canada states that both maximum sizes include wheels and handles. It publishes no weight limit — only that you can lift it unaided. Turning up at the gate with a carry-on on a Basic fare triggers a checked-bag charge plus a service fee, quoted at $65–78 including tax.
Measure the outside, wheels and handles included — that’s what they measure at the gate.

The anti-theft option that actually fits — slash-resistant panels, locking zips, RFID pocket, and a 13-inch laptop sleeve, all inside United’s width.
Pacsafe’s own site is JavaScript-gated, so this comes from a retailer spec rather than the brand. The 0.2 inches of width margin rests on that number.
A tote-shaped answer to the Narwey. Under a pound, folds flat, and doubles as a packable second bag stuffed inside a bigger case.

Yes — 43 × 33 × 16 cm, or 17 × 13 × 6 inches. It goes under the seat in front of you.
No — it is 0.5 inches over. Air Canada allows 21.5 × 15.5 × 9 inches, and the standard US 22 × 14 × 9 does not fit inside that.

Of the bags we track, 7 of 16 carry-ons fit the cabin limit and 3 of 25 personal items fit the under-seat limit.
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.
