How Big Should a Backpacking Bag Be?

By Michael Ferguson

When it comes to backpacking, the size of bag you choose is one of the most important decisions you can make. A backpack that is too big can be cumbersome and uncomfortable, while one that is too small can leave you without enough space to carry all your supplies. Finding the right size bag for your needs can mean the difference between an enjoyable trip and a miserable one.

Factors To Consider When Choosing a Backpacking Bag Size

The first thing to consider when choosing a bag size is what type of terrain you’ll be traveling through. If you’ll be navigating rocky trails or will be trekking through deep snow, you’ll need a larger bag so that your gear won’t get damaged. On the other hand, if you plan on taking short hikes in mild climates, a smaller bag should suffice.

Another factor to consider is how much gear you’ll need to bring along. If you plan on bringing bulky items such as a tent or sleeping bag, then opt for a larger size backpack. However, if all you need are necessities such as water, snacks, and clothing then a smaller pack should do the trick.

Size Guidelines For Backpackers

  • Lightweight Day Trips: For day trips or ultralight backpacking trips opt for packs that range from 20-35 liters. These bags are designed to hold just the essentials like water and food.
  • Weekend Getaways: For weekend getaways where more gear is needed opt for bags between 40-50 liters. These bags will provide enough space for items such as tents and sleeping bags while still remaining relatively lightweight.

Longer Trips: For longer backcountry excursions or multiple day hikes opt for packs between 50-75 liters. These larger bags provide plenty of space for bulky items like tents and sleeping bags as well as additional clothing layers.

Conclusion: How big should a backpacking bag be?

The answer depends on several factors including terrain type, length of trip, and how much gear needs to be carried. Lightweight day trips typically require packs ranging from 20-35 liters while weekend getaways favor 40-50 liter packs; whereas longer trips require 50-75 liter packs. With these guidelines in mind, it should be easier to choose the perfect sized backpack for your next backpacking adventure!
