You don't want the cost and hassle of checking luggage. But you still want to max out your packing space.
The best size of backpack for the most packing space and still being allowed as a carry on is 40 liters.
How big is a 40L backpack?
A 40L backpack measures about 22 x 14 x 8 inches (55 x 35 x 20 cm). At this size, you can use your backpack as a carry on, even on budget airlines and when flying internationally. Most airlines allow 40L bags in the overhead bin.
The US max is 45 liters, but you might have to check that bag when you travel abroad.
A 40L travel bag will fit a week's worth of clothes, toiletries, accessories, and a computer. That's everything you need for your next big trip.
