The size of carry-on luggage is typically limited to 22 inches long, 14 inches wide, and 9 inches high, including wheels and handles. These measurements may vary slightly depending on the airline, but the general rule of thumb is to stay within these dimensions to ensure your bag fits in the overhead bin or under the seat in front of you
. Some airlines may have additional restrictions on the weight of the carry-on luggage, so it's important to check the specific requirements of the airline you are flying with.
