What Size Backpack Do I Need for Hiking
A hiking backpack of the appropriate size is required for all types of adventures
Whether you are going on a relaxing day hike or intend to conquer challenging terrain coupled with unforgiving weather for several days, a backpack is among the top accessories needed for outdoor trips It’s designed to carry all the items you need for a fun and safe trip, which is why it’s so important to choose a pack of the proper size
Hike Duration
How long your hiking expedition will be is the primary consideration when deciding on the capacity of your backpack:
Day hikes
A day or travel pack that is 10-25L large is perfect for a short day hike It will have just the right amount of space to carry your water bottle, snacks, and other gear including a jacket or change of clothes and sun protection
Weekend hike
A backpack that’s 20-35L large is recommended for a two or three-day hike You will need slightly more gear, especially if you will be carrying your own camping or cooking gear as opposed to spending the night in a hotel or other accommodations
Over 3 days
You should be using a backpack with at least 35L capacity for hikes that are 3 days or more This is recommended even if you are going to be staying in rented accommodation Keep in mind that the longer your hike is, the higher the chances are that you may be exposed to unpredictable weather so you should prepare for this by packing enough; in addition you will also need more clothes and have more gear for hikes this long
Multi-day hikes
If you are heading out to a multi-day camping and hiking trip, you should consider a backpack that can fit 50L and up It will allow you to bring all your essentials plus other gear including a sleeping bag, sleeping pad, and tent more However, it’s not uncommon for some hikers to use backpacks this size even for weekend trips if they have to carry three of the biggest and bulkiest hiking gear themselves: tent (or any other form of shelter for the night), sleeping pad, and sleeping bag
Multi-week trips
For trips that entail 2 weeks or more of hiking especially in the backcountry, it’s best to go with a backpack that is at least 60L or more in capacity It will allow you to carry everything included with smaller trips as well as other gear that you might need for added comfort because it’s likely you will need bulkier goods such as:
Take note of the backpack weight too, before and after it’s been packed Loaded hiking backpacks (or any backpack for that matter) should not weigh more than 20% of your own body weight to prevent any shoulder or neck pains, and to prevent injury
Hike Location
In addition to the length of your trip, where you are camping also plays a big role For example, you would be needing significantly less clothing if you will be spending a week in the beach, as compared to the cold mountains or backcountry
This is why it’s important to invest time in researching the climate of the destination you intend to travel to It also helps to check the forecast right before you leave to double check that you have everything you need to stay dry, warm, and comfortable no matter what happens
Remember that if you are hiking in the mountains, no matter what the altitude is, the conditions can change at any time without any warning For these reasons you will be needing a windproof jacket, waterproof clothes, and a change of clothes Similarly, the weather can also change when you are in an island; rain, fog, heat, and humidity can strike at any time
If you are hiking in a destination with arid climates, there can be stark differences in the temperatures during the day and at night In the daytime, you’ll need light clothing, while thicker clothing to keep you warm is necessary for the nighttime
The climate of the destination you are traveling to will impact the type and amount of gear you will be packing, thus it will impact the capacity of your backpack In addition, it should also guide you on the material your backpack is made of, as well as any technical features you should look out for
Body Fit
Last but not least, before you shell out money on a hiking backpack that ticks all the boxes capacity-wise, you should also make sure it’s the appropriate size for your size and frame
Here are some tips:
1 Get your torso length To do this, stand straight with your head tilted back then locate your C7 It’s the bump near the intersection of your neck and shoulders After this, use your thumbs to locate your hip bones by drawing an imaginary line from left to right hip bone
Ask a friend to measure the distance from the C7 down to the area between the hip hones This is your torso length
2 Next, get your hip width Use a measuring tape to locate your hips, then measure the length between This measurement will help you ensure that if you get a hip belt on your hiking backpack, it will fit properly
Keep in mind that the hips are higher than your waist, so it should have a similar measurement to your pant size with a small difference
Once you have these measurements in place, you can use the size charts provided by backpack manufacturers It will provide guidance on whether you should be buying small, medium, or large size pack though backpack sizes can vary depending on the brand

Frequently Asked Questions
How to wear a hiking backpack
Once your hiking backpack has been loaded, there’s a right way to wear it
Many beginners make the mistake of hoisting it up using the shoulder straps This can wear out the harness while making it difficult to balance the pack and get it onto your back
The correct way to put on a loaded hiking backpack is to loosen all of the straps a little, tilt the backpack upright, then stand by the back panel Be sure that you are standing with your legs apart and knees bent, then grab the haul loop, lift the pack up your thigh while keeping a grip on the haul loop Slide your other arm through one of the shoulder straps until the padding cradles your shoulder
Next, lean forward then swing the backpack onto your back The hand that was holding the haul loop can then be slid through the other shoulder strap
Adjust and tighten the straps to the right fit
