You should consider on what season and how long you’re going to go on your trip when looking for the right backpack size. More than anything else, these two factors should decide what the dimensions of your backpack should be.
Backpack for Summer Hiking
The backpack size for day hiking is 1,500-2,000 cubic inches (25 to 35 liters). If the trip lasts for two nights, increase this total to 2,500 or 3,000 cubic inches (40 to 50 liters).
For a 3 to 5 night trip, the size should be 3,000 to 4,000 cubic inches or 50 to 65 liters. If it is for at least five nights, the capacity should be 4,000 to 5,000 cubic inches or 50 to 65 liters at the minimum.
Backpack for Hiking in The Spring and Fall / Autumn
For day hiking you will need a backpack capable of carrying 2,000-2,500 cubic inches or 35 to 40 liters. If the trip lasts for two evenings, increase this total to 3,000 to 3,50000 cubic inches (50 to 55 liters).
If you’ll be hiking for a minimum of three nights (maximum five nights) the capacity should be 4,000 to 5,000 cubic inches (65 to 80 liters). The capacity should be 4,000 to 5,000 cubic inches or 50 to 65 liters at the minimum if it is for at least five night.
Winter Hiking Backpack
The requirements for winter hiking are a little bit different. You will need a backpack capable of carrying 2,500-3,500 cubic inches or 40 to 55 liters for day hiking. If the trip lasts for one or two nights, the capacity should be 4,000 to 5,000 cubic inches (or 65-80 liters).
For hiking that takes three to five nights maximum, the backpack should be able to carry 5,000 cubic in (80 to 90 liters). The capacity should be 4,000 to 5,000 cubic inches or 50 to 65 liters at the minimum if it is for at least five night.
Backpack Types
Daypacks are very popular among summer hikers. These are basically small backpacks. Their small size makes them ideal to carry during hot days. When shopping for daypacks, think of the trip duration.
If you’ll be hiking for at least a couple of days, make sure the backpack has enough room for extra clothing. The backpack size for winter hiking needs to be a little bigger. You’ll need thicker clothes.
Backpacks use internal or external frames. The internal frames are more popular nowadays because it provides mobility and balance. This is most suitable for hiking and mountain climbing. However the external backpack is preferred by some as there is space between the backpack and one’s back.
What to Carry
Food, water and clothing are the bare necessities. Make sure to carry the amount of clothing needed; you don’t want to run short, but don’t fill your backpack with stuff you won’t use. Don’t forget to carry medical kits.
Having a compass with you is also a good idea. A flashlight, batteries and a cell phone are also essential especially for new hikers.
While manufacturers may use the same backpack size measurements, each has its own nuances. Spend some time trying them to see which one you’re most comfortable with.
