A common sized bag for carry-on luggage is 22x 14x 9. Most airlines have a carry-on weight limit of 40 pounds. International airlines may have different restrictions for carry-on luggage.

For the 2026 travel season, carry-on weight limits are increasingly standardized but still vary by carrier and class. On most major international airlines, the standard weight limit for an economy-class carry-on is 7 kg to 8 kg (15-17.6 lbs). However, some full-service carriers like British Airways are notably generous, allowing up to 23 kg (51 lbs), provided the passenger can lift the bag into the overhead bin unassisted. In contrast, many budget airlines in Europe and Asia strictly enforce a 7 kg limit, often weighing bags at the gate and charging heavy fees for any excess. Business and First Class passengers usually enjoy higher limits, often up to 10 kg to 15 kg per bag. It is also important to note that many airlines now implement a "one-bag" rule, meaning your laptop or handbag must fit inside your main carry-on. Always check your specific ticket in 2026, as "Basic Economy" fares are increasingly excluding any overhead bin access entirely, allowing only a small personal item.
