What does 56x45x25cm mean? 56x45x25cm (All Parts) = EXACTLY the Maximum Allowance Cabin Luggage Size for Easyjet and British Airways / 53.5x45x25cm (Body) / Weight 2.3kg / Capacity: 60L.
In terms of kilos, a full 55 litre backpack will weigh around 14kgs approximately whereas a full 70 litre backpack will weigh around 20kg. That's too much to travel around the world with. Naturally, as a backpacker, you want to travel as light as possible so I would recommend taking a 55litre.
A 50L+ backpack is a great friend to those travelling for a few weeks. These bags are spacious and can accommodate a number of outfit changes before you ever have to visit a laundromat. But don't be tempted to fill your pack to its capacity before you've even left - remember to save space for souvenirs!

Bottom Line. Is a backpack a carry on? In many cases, as long as it's not larger than about 55L, yes, you can use many backpacking backpacks as a carry on.
One MIGHT get away with a 55L backpack, but 40L would be much more reliable. Carry-on limits are defined by total linear inches, typically 45 or fewer, also maximum dimensions particularly length, generally 22 inches. 22 x 13 x 9 is 2574 cu. inches, 42L.
