Even if you're a heavy packer, you should be able to take a 45L pack away for a weekend. A light packer could easily do with a bag like this for a week. With that in mind, here's a packing list for what you can fit in a 40+ backpack.
The best carry-on travel backpack sizeYour backpack will generally be allowed as a carry-on if it's under 50 liters, or about 22 x 14 x 9 inches. Get a 45-liter backpack if you want to carry as much stuff as possible on the plane with you.
Multiday Packs: 50-75 litersA light packer will have ample room for five nights or more with a multiday backpack, which is typically a 50L backpack or larger. These are designed to carry more food and cooking fuel than a weekend pack, as well as extra clothes and layers.
Trips of 5 days or more usually call for packs of 70 liters or more. These are also usually the preferred choice for winter treks lasting more than 1 night. (Larger packs can more comfortably accommodate extra clothing, a warmer sleeping bag and a 4-season tent, which typically includes extra poles.)
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!

You can always go smaller, but I wouldn't recommend anything smaller than 35L — unless you're into minimalist travel. The length of your trip really doesn't make much of a difference when it comes to choosing a backpack — so don't buy a huge backpack because you're going on a 6-month journey.

Effects of an overweight backpackAn overweight backpack causes the body to compensate for the extra weight. If you lean forward to compensate, it reduces your balance making it easier to fall. The extra weight can distort the natural curve of the middle and lower back, causing muscle strain.
10 to 19 liters: For light loads and 13-inch laptops. 20 to 29 liters: Best for students and 15- to 16-inch laptops. 30 to 39 liters: For super-size workloads and weekend trips. 50 to 80 liters: For hikers and campers.
Size Matters (but Bigger Isn't Better)Like a few other things in life, size matters when it comes to choosing a backpack — but not in the way you might think. Based on many years of dragging excessively large backpacks around the world, I have to say bigger is not better. You do not need an 80 or 90 litre pack.
