Airlines have specific guidelines when it comes to carry-on bags, and it's essential to familiarize yourself with them before your trip. Typically, the maximum size for a carry-on bag is around 22 inches tall, 14 inches wide, and 9 inches deep. However, it's always best to check with your airline, as these dimensions can vary.
For example, if you're flying on a budget airline, they may have stricter size restrictions to ensure everyone's bags fit in the overhead compartment. On the other hand, if you're flying on a luxury airline, they may be more lenient with their carry-on bag size policy.
