20 Inch

The standard carry-on size for major US airlines typically measures 56 x 36 x 23 cm (22 x 14 x 9 inches), which includes all handles, side pockets, and wheels. Generally, airlines waive fees for carry-ons that adhere to their specific carry-on baggage policy.
Our 20″ is sure to be a great travel carry on in most cases, with some airlines differing in policy.
