Is 30 Liters Enough?
We would like to inform that 30L is simply too small to pack the items you will need for any hiking trips that will take more than a few hours.
What About More than 40 Liters?
On the other hand, while 55L will let you pack everything you’ll need with ease, it can be rather bulky to carry. It’s also important to note, especially if you plan on any airline travel with your backpack, that within that range,
most airlines require you to check in most bags over 45L.
The Best Choice is 40 Liters
So, with that in mind, we think that 40L is the best volume to go with. It manages to strike a perfect balance.
Measuring your backpack
There are typically two types of measurements used when measuring the size of a backpack – the actual height/length/width measurements and the volume, or total carrying capacity. You can generally get a rough estimate of the volume of the bag by calculating its dimensions, but that method is far from 100% accurate.
These measurements are taken in cubic inches and then converted into liters. It should be noted that the measurement is usually rounded to the nearest decimal points, meaning that they aren’t always 100% accurate.
