If you’ve ever packed for a trip and wondered, “How big is a carry-on?” , then you are not alone. Different airlines have different rules, and it can be frustrating to figure out how much luggage is allowed. Don’t worry, this guide will give you the details so you can pack with confidence and avoid surprises at the gate.

Standard carry-on baggage sizes
Most airlines allow carry-on bags to have a maximum size of 22 inches high, 14 inches wide, and 9 inches deep. This size includes wheels and handles, so be sure to measure carefully. While this is the standard size, be sure to check the airline’s specific policy, as some airlines may allow slightly smaller or larger bags.
Why Airline Policies Matter
Every airline has its own carry-on baggage rules. Low-cost airlines, in particular, tend to have stricter limits on baggage size. If your luggage is too large, you may be forced to check it at the gate and pay an additional fee. Checking the airline’s website before packing can save you time and money.
How to measure your carry-on luggage
To make sure your luggage fits, measure its height, width and depth, including any handles or wheels. Use a tape measure to compare it to the airline’s size guide. Don’t forget to consider how your luggage expands when packed. Overpacking may exceed the size limit.
Tips for maximizing luggage space
Choose lightweight clothing and pack versatile items. Use packing boxes to organize items and save space. Roll your clothes instead of folding them so you can fit more in. Remember that liquids must meet TSA size requirements, so stick to travel-size containers.
What if your luggage is too big?
If your luggage does not meet the size limit, you may need to check it at the gate. This usually incurs an additional fee, which can be as much as $50 or more. To avoid this hassle, it’s a good idea to double-check the size of your luggage ahead of time.
Knowing the size of your carry-on luggage is the first step to stress-free travel. By following the rules and packing smart, you’ll be able to breeze through security and enjoy your trip.
