The typical maximum size for a carry-on bag is about 22 inches tall, 14 inches wide, and 9 inches deep (56 cm x 35 cm x 23 cm), including handles and wheels. This size is generally accepted by many airlines such as United Airlines, American Airlines, and Lufthansa, though exact limits can vary slightly by carrier
. Passengers are usually allowed to bring one carry-on bag plus one personal item (like a backpack or purse) that fits smaller dimensions, often around 40 x 30 x 15 cm (16 x 12 x 6 inches)
. Some airlines may have stricter or slightly different size limits, and low- cost carriers might enforce these rules more strictly. Also, weight limits for carry-ons typically range around 7-8 kg (15-18 lbs) but vary by airline and travel class
. In summary, to ensure your carry-on is accepted, aim for a bag no larger than approximately 22 x 14 x 9 inches (56 x 35 x 23 cm), including wheels and handles, and check your specific airline’s policy before traveling.
