How Big of a Bag Do I Need for Backpacking?

By Alice Nichols

Backpacking is an incredible way to experience the outdoors and create unforgettable memories, but it does require packing smartly and efficiently. Figuring out what size bag you need for your backpacking trip can be a difficult decision, as there are many factors to consider.

The first thing to consider is the length of your trip. For a short weekend trip, you may only need a small-to-medium sized bag that can hold a few days’ worth of supplies. In contrast, if you’re planning on a longer journey such as a month-long excursion, you will likely require a large bag to fit all of your necessary items.

Another factor to consider is the type of terrain you will be travelling through.

If you are backpacking through mountainous regions or in cold climates, then it is important to bring along heavier items such as sleeping bags and warm clothes. This means that your bag needs to be able to accommodate larger items while still remaining comfortable enough for you to carry comfortably.

The final factor that should be taken into account when deciding on the size of bag needed for backpacking is how much personal gear you plan on bringing along with you. If you plan on bringing items such as camera equipment or extra clothing, then it may be necessary to invest in a larger bag so that everything fits comfortably and securely.


Overall, the size of bag required for backpacking depends largely on the length and type of trip being taken as well as how much personal gear needs transporting. It is important to research all available options before investing in any particular size so that your backpacking experience can be both comfortable and enjoyable.
