Air Canada Carry-On Size: Standard Article and Personal Item Rules
Air Canada's carry-on limit is 55 x 23 x 40 cm, or about 21.5 x 9 x 15.5 inches, for the standard carry-on article. The smaller under-seat item is 33 x 16 x 43 cm, or about 13 x 6 x 17 inches, for the personal article. The practical packing move is to measure the packed bag including wheels, handles, outside pockets, and straps, then keep medicine, documents, electronics, keys, and valuables in the under-seat bag in case the larger bag is checked at the gate.

What matters first
Use this page as the practical filter before you open booking pages, maps, or official policy documents.
Main bag limit
Air Canada's carry-on limit is 55 x 23 x 40 cm, or about 21.5 x 9 x 15.5 inches, for the standard carry-on article. The smaller under-seat item is 33 x 16 x 43 cm, or about 13 x 6 x 17 inches, for the personal article.
Protect the under-seat item
Medicine, documents, electronics, chargers, keys, glasses, and fragile items belong in the personal item because that is the bag least likely to be taken away.
Keep TSA separate
TSA liquid limits are about contents, not airline bag size. A right-size bag can still fail security if liquids are packed wrong.
Decision system
The planning sequence
Use the sequence below to decide how this should shape the trip.
The real packing check
Measure the packed bag, not the empty shell
Airline baggage rules apply to the object that reaches the airport: wheels, handles, straps, outside pockets, and everything added at the end. A bag that looks compliant empty can fail once it bulges. Measure the packed bag at home, then keep documents, medicine, chargers, keys, and fragile items in the under-seat personal item.
The Air Canada size rule that matters
Air Canada's carry-on limit is 55 x 23 x 40 cm, or about 21.5 x 9 x 15.5 inches, for the standard carry-on article. The smaller under-seat item is 33 x 16 x 43 cm, or about 13 x 6 x 17 inches, for the personal article. Measure at home with the bag packed, because soft bags and outside pockets can grow past the limit once they are full.
Why the personal item is the safety bag
The personal item should not be treated as random overflow. It should hold documents, medication, valuables, electronics, a charger, keys, glasses, and anything needed if the larger bag is checked or delayed.
How fare, cabin, or route changes the decision
Air Canada uses a standard article plus personal article model, so travelers should size each bag by role instead of treating both as full carry-ons The safest move is to confirm the allowance on the official page and in the reservation before arriving at the airport.
What happens on full flights and smaller aircraft
Even a compliant bag can be checked when overhead bins fill or the aircraft has smaller bins. Fragile items, lithium batteries, documents, and medicine should never be buried in the overhead bag.
TSA rules are a different checkpoint
Airline dimensions decide whether the bag fits onboard. TSA rules decide whether the contents clear security. Liquids, gels, aerosols, creams, and pastes in a carry-on generally need travel-size containers in a quart-size bag, with specific exceptions.
Deep Arrival recommendation
Air Canada travelers should size the main bag conservatively and make the personal item the essential kit. The best setup is boring at home and painless at the gate: measured bag, flat pockets, accessible liquids, and no irreplaceable items in the overhead bag.
