24-26 liters is considered a medium-size backpack and is probably the most popular bag capacity out there. It's great for taking to school or work, depending on the styling, and can also be a great travel pack for taking on a plane.
Volume: A 45L backpack is the maximum-sized carry on allowed on most US airlines. For international or budget airlines, choose a bag under 40L. If you want to pack ultralight, anything 35L or under can be carried on virtually any airline. Dimensions: The common 45L volume is usually measured as 22 x 14 x 9 inches.
