Before using the carry-on size checker you will need to measure your suitcase correctly.

A bag that appears small enough may exceed the permitted dimensions once you include its wheels, handles, and external pockets.

1. Measure the height

Make your suitcase stand upright and measure from the bottom of the wheels to its highest point.

Don’t forget to include any fixed handles or other parts that stick out.

2. Measure the width

The width is the front of the suitcase.

Measure across the widest part of your suitcase, including side handles or other parts like pockets.

3. Measure the depth

Measure from the front of the suitcase to the back at its deepest point.

Include external pockets and any bulges caused by packing, usually pocket don’t take too much size in the suitcase depth.

4. Check the packed dimensions

Measure your suitcase as you intend to travel with it.

If it has an expandable section, remember that opening it can increase its depth and cause the bag to exceed the airline’s limit.

What Do the Checker Results Mean?

The results you get from the checker will help you understand which airline your suitcase fits well.

Your bag is within the listed size limit

If all dimensions are within the listed limits, your suitcase appears to meet the size requirements used in the comparison.

However, size is only one part of an airline’s baggage policy.

You may also need to meet a weight limit and have a ticket that includes a cabin bag.

Your bag exceeds one or more limits

If one or more dimensions exceed the listed maximum, your suitcase may not qualify as carry-on baggage under that airline’s rules.

Check the airline’s official baggage policy before traveling.

Depending on your ticket and the airline’s options, you may need a smaller suitcase, an additional baggage allowance, or checked baggage.

You need to confirm the airline’s rules

This airlines and airport carry-on size checker is a useful guide, but it cannot guarantee that an airline will accept your bag.

The rules may depend on your fare, route, aircraft, and the specific baggage allowance included with your booking.

Always verify the applicable rules before departure.

Carry-on bag size limits: what you need to know

There is no single carry-on bag size limit that applies to all the airline.

Each airline has its own baggage policy, and the permitted dimensions and weight can differ.

Here are the main things to check before choosing a cabin suitcase.

Maximum length, width, and height

Airlines commonly specify maximum baggage dimensions using three measurements: height, width, and depth.

Some publish the maximum for each dimension, while others also have a combined total which you can use this calculator to find.

Do not assume that a suitcase will be accepted simply because its combined dimensions appear to be within a particular limit.

Carry-on weight restrictions

Some airlines have a maximum weight for cabin baggage, while others have different rules depending on the ticket or route.

If your airline has a weight limit, weigh your packed suitcase and compare it with the applicable allowance.

A suitcase can meet the size requirements and still exceed the permitted weight.

Different tickets may have different allowances

The baggage allowance included with your booking may depend on the fare you purchased.

Some basic fares include only a small personal item, while other fares or optional add-ons may allow a larger cabin suitcase.

What If Your Carry-on Bag Is Too Large?

If your suitcase is above your airline carry-on dimensions, do not assume it will be accepted because it just few inches larger even though sometimes it will.

But here is what to keep in mind:

  • Measure your suitcase again: Make sure you are using the correct units inches or centimeters and measuring all the three dimensions.
  • Double check your ticket details: If you already book your flight then your booking may include a different baggage allowance from the airline’s basic fare.
  • Consider a smaller bag: If your suitcase exceeds the applicable limit, a smaller cabin bag may be the simplest solution.
  • Consider checked baggage: If the suitcase is too large to sue as carry-on, then using a small one is a great option or check in it is maybe is necessary.

Carry-on Bag vs. Personal Item: What’s the Difference?

A carry-on bag and a personal item do not have the same restrictions.

A carry-on bag is typically a suitcase or larger cabin bag that you can place in the overhead compartment.

A personal item is generally a smaller bag, such as a handbag or a purse, A Laptop bag, or small backpack, that you can place under the seat in front of you.

The permitted size, number of bags, and included allowance vary by airline and fare.

Some tickets include a personal item but require an additional purchase for a larger cabin suitcase.

Before packing, check which type of bag your ticket permits and measure it against the corresponding restrictions.

If you are checking a smaller backpack or handbag, use our personal item size checker to help compare its dimensions with the applicable limits.

How to Choose the Right Carry-On Suitcase

Choosing a suitcase that meets your airline’s restrictions can make travelling easier and reduce the chance of baggage problems at the airport.

Keep these points in mind if you are looking for a cabin or carry-on suitcase.

Take a look at the external dimensions

Do not rely only on the dimensions listed for the suitcase’s main compartment.

Look for the complete external measurements, including wheels and handles, and compare them with the limits for your intended airline.

How much the empty suitcase weight

A lightweight suitcase leaves more of your permitted baggage weight available for clothing and other travel essentials when a weight restriction applies.

Remember that the total weight includes the suitcase itself and everything packed inside it.

Watch out for expandable suitcases

Expandable luggage can have extra packing space, but opening the expansion section increases the suitcase’s dimensions.

Measure it expanded if you plan to use during your trip.

Keep an eye on your most strict flight

If your trip involves many airlines, compare the baggage allowances for each flight.

Choose a suitcase that fits the applicable restrictions across your itinerary to help you avoid having to change bags partway through your trip.
