Is a backpack considered a small carry-on bag?
Souleymane Enok
Traveling by plane often raises a practical question: is a backpack considered a small carry-on bag? Between carry-on items, personal items, and cabin suitcases, rules vary by airline, which can quickly lead to confusion.
Some airlines allow a small backpack provided it meets specific dimensions, while others apply stricter restrictions on weight and size. A simple excess of a few centimeters can result in additional fees at boarding.
In this article, we will clarify whether a backpack can be accepted as a small carry-on bag, what dimensions are generally allowed, and how to avoid unpleasant surprises at the airport.
Is a backpack considered a small carry-on bag?
Yes, a backpack can be considered a small carry-on bag, provided it respects the dimensions imposed by the airline. This point is essential: it is not the type of bag that determines its status, but rather its size and sometimes its weight.
In the majority of cases, airlines distinguish between two categories:
- The small carry-on bag (also called a personal item)
- The standard carry-on bag (cabin suitcase placed in the overhead compartment)
The small carry-on bag must generally fit under the seat in front of you. That is where the backpack comes into play.
The backpack as a personal item
A backpack is often perfectly suited to the "small carry-on" format. Why? Because it is flexible, compact, and easy to slide under the seat.
However, the allowed dimensions vary by airline. As a guide, the most common sizes for a small carry-on bag are around:
- 40 x 30 x 20 cm
- 40 x 25 x 20 cm
- 45 x 36 x 20 cm
If your backpack meets these measurements (handles and pockets included), it will generally be accepted as a small carry-on bag.
Beware of overly bulky backpacks
Not all backpacks are considered small carry-on bags. Large hiking models or very thick bags may exceed the allowed dimensions.
A 50-liter backpack, for example, will often be classified as a standard carry-on or even checked baggage if it exceeds the limits.
It is therefore essential to:
- Check the exact dimensions of the bag
- Compare with your airline's rules
- Measure the bag once packed (as it may expand)
Weight also plays a role
Some airlines impose a weight limit for all carry-on baggage. Even if the bag meets the dimensions, excessive weight can be an issue.
It is therefore advisable to weigh your bag before departure, especially if you are carrying a laptop or heavy items.
Why is a backpack a good choice for the cabin?
The backpack offers several advantages as a small carry-on bag:
- Ease of transport
- Flexibility and adaptability
- Optimized organization
- Speed during security checks
It allows you to keep your essential items within reach: documents, phone, charger, tablet, empty bottle, etc.
What dimensions must a backpack meet to be accepted in the cabin?
For a backpack to be accepted in the cabin, it must first and foremost meet the dimensions imposed by the airline. Contrary to popular belief, it is not the type of bag that determines its acceptance, but its exact size once filled.
Most airlines distinguish between two categories: the small carry-on bag (personal item) and the standard carry-on bag. If you want your backpack to be considered a small carry-on bag, it must be able to fit under the seat in front of you.
Common dimensions for a small carry-on bag
Even though each airline applies its own rules, the most frequent sizes for a small carry-on bag are:
- 40 x 30 x 20 cm
- 40 x 25 x 20 cm
- 45 x 36 x 20 cm
These dimensions include handles, outer pockets, and any extensions. A backpack that slightly exceeds these may be rejected if the staff determines it does not fit into the sizer.
It is important to note that some low-cost airlines apply very strict checks, including the use of metal sizers at boarding.
Dimensions for a backpack considered a standard carry-on
If your backpack is bulkier, it may be classified as a standard carry-on. In this case, the maximum allowed dimensions are generally around:
- 55 x 35 x 25 cm
- 55 x 40 x 23 cm
This size corresponds to a classic cabin suitcase. The bag will need to be placed in the overhead compartment.
Note: this type of carry-on baggage is sometimes subject to fees, depending on the airline.
Volume in liters can be misleading
Many backpacks are sold based on their capacity in liters (20L, 30L, 40L, etc.). However, this information is not enough.
A 30-liter bag can sometimes exceed the allowed dimensions depending on its design. It is therefore essential to check the measurements in centimeters, especially once the bag is filled.
Weight can also be checked
Some airlines impose a weight limit for carry-on baggage (often between 8 and 10 kg). Even if the bag meets the dimensions, excessive weight may result in it being checked into the hold.
It is therefore advisable to weigh your bag before departure.
How can you be sure your bag will be accepted?
To avoid unpleasant surprises:
- Measure your backpack while filled
- Check the exact dimensions on the airline's website
- Avoid overstuffing outer pockets
- Opt for a flexible rather than a rigid model

In summary, to be accepted in the cabin as a small bag, your backpack must generally meet a size close to 40 x 30 x 20 cm. For a standard carry-on, the limit is around 55 x 35 x 25 cm.
Conclusion
Ultimately, a backpack can certainly be considered a small carry-on bag, provided it strictly follows the dimensions imposed by the airline. It is not the shape of the bag that counts, but its size once filled.
A compact model, generally around 40 x 30 x 20 cm, will be accepted as a personal item and can be placed under the seat in front of you. On the other hand, a bulkier backpack may be classified as a standard carry-on, or even refused in the cabin if it exceeds the allowed limits.
To avoid additional fees and unpleasant surprises at boarding, it is essential to:
- Check your airline's official dimensions
- Measure your filled bag
- Check the total weight
In short, the backpack is often the most practical and flexible option for traveling light in the cabin. When well-chosen and well-prepared, it becomes an ideal ally for a stress-free trip.
