Carry-On Dimensions Decoded: What Size Suitcase Do You Really Need in Canada?

Last updated: September 2026

Carry-on sizing can look like a game of numbers.

You might see one suitcase advertised as 22 × 14 × 9 inches, another listed as 21.5 × 15.5 × 9 inches, and another measured in centimetres instead. So which one is actually the right size for your trip?

For Canadian travellers, the answer depends on the airline.

There is no single carry-on dimension that applies to every carrier. Air Canada, WestJet and Porter, for example, all publish different maximum dimensions. That makes the familiar 22 × 14 × 9-inch measurement worth understanding, but not necessarily the best measurement to use for every Canadian itinerary.

What Does 22 × 14 × 9 Mean?

The numbers represent the exterior dimensions of a suitcase:

  • 22 inches: height
  • 14 inches: width
  • 9 inches: depth

It is a common carry-on reference, particularly for U.S. and international airlines. It is also directly relevant to Canadian travellers because WestJet's current maximum carry-on dimensions are 56 × 36 × 23 cm, or 22 × 14 × 9 inches.

That creates an important distinction when comparing airlines. A suitcase that reaches WestJet's 56 cm maximum height can be 1 cm taller than Air Canada's 55 cm maximum.

Air Canada lists a maximum standard carry-on size of 55 × 40 × 23 cm, or approximately 21.5 × 15.5 × 9 inches, with wheels and handles included.

So if you are flying Air Canada, WestJet or another carrier, always check the specific airline's allowance rather than assuming 22 × 14 × 9 applies universally.

How Canadian Airlines Compare

The easiest way to understand carry-on sizing is to look at the airlines you are most likely to fly.

Air Canada: Maximum standard carry-on dimensions are 55 × 40 × 23 cm (21.5 × 15.5 × 9 in), including wheels and handles.

WestJet: Maximum carry-on dimensions are 56 × 36 × 23 cm (22 × 14 × 9 in), including wheels and handles.

Porter: Maximum standard carry-on dimensions are 55 × 40 × 23 cm (21.5 × 15.5 × 9 in). Whether a standard carry-on is included depends on your fare.

Flair: Carry-on allowances can vary based on the fare and itinerary, so check the current baggage allowance attached to your booking before flying.

The takeaway is simple: there is no single suitcase size that guarantees compliance across every Canadian airline and fare.

Why Canadian Travellers Should Pay Attention to Wheels and Handles

Imagine you find a suitcase with a case that measures less than the airline's maximum.

It seems like you are safely within the limit.

Then you add the wheels and handles.

The total exterior measurement may be larger than the case itself.

That is why Travelpro lists both case dimensions and overall dimensions on its luggage. The overall measurement gives you a more useful number to compare against an airline's baggage allowance.

When shopping for a carry-on, look beyond the size of the main compartment. Check the full dimensions of the suitcase as you would actually bring it to the airport.

Why Carry-On Dimensions Vary by Airline

Airlines have different aircraft, cabin configurations and baggage policies. They also have different approaches to fares and baggage allowances. Travelpro's size guide highlights the key differences.

This means two airlines flying similar routes can have different carry-on requirements.

Even within one airline, your fare can affect what you are allowed to bring.

Air Canada is a good example. Its current policy allows a standard carry-on and personal item on eligible fares, but Economy Basic tickets purchased on or after January 3, 2025 can have more restrictive baggage allowances on certain itineraries, including travel within North America.

Porter also varies its carry-on allowance by fare. Its Basic fare generally includes only a personal item, while higher fares include a standard carry-on.

In other words, knowing your suitcase dimensions is only half of the equation.

You also need to know what your ticket includes.

The Canadian Carry-On Sweet Spot

For Canadian travellers who fly Air Canada or Porter regularly, a suitcase around the 55 × 40 × 23 cm maximum can make sense, provided its overall dimensions comply with the current rules.

WestJet gives travellers slightly more room in one dimension, with a maximum of 56 × 36 × 23 cm. That means a suitcase designed around the familiar 22 × 14 × 9-inch format can fit WestJet's published maximum while exceeding Air Canada's 55 cm height limit by 1 cm.

If you regularly cross the border or fly internationally, you may want to think more strategically.

A suitcase that works well for one Canadian airline may not be the ideal choice for a European airline with a slimmer cabin-bag allowance.

That is where a more compact international carry-on can offer flexibility.

Travelpro's international luggage, for example, includes designs around 55 × 40 × 20 cm, a format used by a number of international airlines.

If your travel calendar includes Montréal to Paris one month and Montréal to New York the next, considering the stricter allowance can help you choose one carry-on that works across more trips.

Don't Confuse Carry-On Size With Packing Capacity

A suitcase's external dimensions do not tell the entire story.

Two carry-ons can have nearly identical measurements but offer different usable packing space depending on their interior construction, wheel housing, handle system and organization.

This is where luggage design becomes important.

Travelpro builds its luggage with features designed around real-world travel, including organized interiors, durable materials and smooth-rolling wheel systems.

A carry-on should not simply fit inside an airport sizer. It should also be easy to pack, lift, roll and access throughout your trip.

How to Pack a Canadian Carry-On

Once you have chosen a suitcase that meets your airline's requirements, the next step is making the most of the space.

For a short trip, start by planning outfits rather than packing individual pieces at random.

Choose a few pieces that can be mixed and matched. Wear your bulkiest shoes while travelling. Keep a lightweight layer accessible for the flight. Use packing cubes to group clothing and accessories so you are not digging through the entire suitcase at your destination.

And leave a little breathing room.

A suitcase that closes easily at home is much more useful than one that requires you to sit on it before every flight.

What About Winter Travel?

Canadian travel comes with one obvious packing challenge: the weather.

A summer weekend in Montréal is very different from a February trip to Vancouver, Calgary or Québec City.

During colder months, think strategically about what actually needs to go inside your carry-on. Wear your bulkiest coat and boots rather than packing them whenever possible. Choose lightweight layers that can be combined instead of bringing several heavy sweaters.

Your suitcase dimensions do not change with the season, so your packing strategy has to.

Check Before You Fly

Carry-on rules are not something to guess.

Before departure, check the airline operating each flight on your itinerary. Pay attention to:

  • Maximum dimensions
  • Whether wheels and handles are included
  • Weight restrictions
  • Personal-item allowances
  • Fare-specific baggage rules
  • Whether the allowance differs by route

Air Canada specifically states that carry-on dimensions include wheels and handles, and that a carry-on must be light enough for you to place in the overhead bin without assistance.

Those details are just as important as the measurements printed on the suitcase.

The Takeaway

So, is 22 × 14 × 9 inches the right carry-on size for Canadian travellers?

Sometimes.

But there is a better way to think about carry-on luggage: choose the dimensions based on the airlines you actually fly.

For Air Canada travellers, 55 × 40 × 23 cm is an important reference. For WestJet, the maximum is 56 × 36 × 23 cm, which aligns closely with the familiar 22 × 14 × 9-inch format. For Porter, the published maximum is 55 × 40 × 23 cm.

If you regularly travel internationally, a slimmer 55 × 40 × 20 cm suitcase may provide greater flexibility across stricter cabin allowances.

The goal is not to find the biggest suitcase you can squeeze into the overhead bin. It is to find a carry-on that gives you enough room to pack comfortably while keeping you within the rules.
