Flight Cabin Carry-on Hard Cases

Cabin Size hard case

Cabin hard cases, also known as carry-on hard cases, refer to luggage that meets an airline’s maximum size allowance for items brought into the aircraft cabin. These size limits exist because cabin storage space is limited, especially in the overhead compartments.

Check-in luggage is usually larger than carry-on luggage and has a higher size allowance. However, there are still maximum size restrictions, especially for oversized, irregular-shaped, or non-standard luggage. Please check with your airline before travelling, as baggage rules may vary depending on the airline and aircraft model.

For carry-on luggage, avoid packing dangerous items such as cutters, sharp tools, or anything that could potentially be used as a weapon onboard the aircraft.

For check-in luggage, do not pack batteries, flammable items, or other restricted materials. If a fire starts inside the checked baggage storage area during a flight, it is more difficult to detect and extinguish quickly.

Typical Size Restriction

The carry-on luggage size for most airlines is typically limited to 56 x 35 x 23 cm (22 x 14 x 9 inches), including handles and wheels. Or a quick and simple guide by the airlines is to take the sum of the 3 dimensions to be <115cm. For this example, 56 + 35 + 23 = 114cm which is less than 115cm.

Note: Not all airlines are this strict in their luggage rules. It’s best to check with the specific airline you’re travelling with, as the size and weight restrictions may vary. Some airlines may have more strict guidelines. It is best to check directly with your airline before you travel to avoid any unexpected inconvenience.

Nominal Size vs. Actual Size: What’s the Difference?

When shopping for luggage, you may notice that the advertised size does not always match the suitcase’s full exterior dimensions. This is because manufacturers often distinguish between nominal size and actual size.

1. Nominal Size — The Advertised Size

The nominal size is the size label commonly used by manufacturers to classify a suitcase, such as a 20-inch carry-on or a 28-inch checked suitcase.

What it measures:
Nominal size generally refers to the height of the suitcase’s main packing shell. Depending on the manufacturer, components such as wheels, handles, and exterior pockets may not be included.

Why it is used:
Nominal sizing provides shoppers with a simple way to compare luggage and understand its general size category and packing capacity.

2. Actual Size — The Full Exterior Dimensions

The actual size refers to the suitcase’s complete external dimensions, measured from its furthest points.

What it measures:
Actual dimensions typically include the suitcase body, spinner wheels, handles, side grips, and any protruding exterior features.

Why it matters:
Airlines generally base their baggage restrictions on the suitcase’s overall external dimensions, not its advertised nominal size. When luggage is measured at check-in or placed into a baggage-sizing frame, the entire suitcase – including wheels and handles – is taken into account.

Why the Difference Matters

A suitcase advertised as 20 inches may have an actual overall height of 22.5 inches once the wheels and handles are included.

For example, if an airline allows cabin baggage with a maximum height of 22 inches, a suitcase marketed as a “20-inch carry-on” could still exceed the airline’s limit.

For this reason, always check the manufacturer’s overall dimensions – height, width, and depth – rather than relying only on the nominal size printed on the product label.

Before You Travel

To make sure your suitcase meets an airline’s baggage requirements, compare its actual exterior dimensions, including wheels and handles, with the airline’s published size limits.

If you have a specific suitcase or airline in mind, provide the brand and model of the luggage or the airline name to check whether it meets the required dimensions.
