What size trekking backpack do I need?

Choosing the right backpack isn’t just about capacity. The larger the pack, the more important a well-fitting, adjustable back system is. A back system with anatomically S-shaped shoulder straps that wrap around the shoulder will create superior carrying comfort allow for unrestricted range of movement. And that’s why the backlength of a backpack is also key.
How do I measure back length?
- Measurement point 1 "neck vertebra": Tilt your head down. The C7 vertebra bulges below the base of the neck.
- Measurement point 2 "lumbar region": Use a belt to help you measure. Position the belt across the top of the hip bone. This is at the same height as the L3 lumbar vertebra.
A measuring tape can then be positioned on the C7 vertebra, and the measurement taken between this and the top of the belt or top of the hip bone. You can measure your back length by following these instructions. Once you have established your back length, you can use our size chart to see what size trekking backpack is right for you.

Types of trekking
Whether it’s a long-distance thru-hike, hut-to-hut mountain hike, following a pilgrim’s trail or a full-on wilderness expedition, deuter has a trekking backpack that fits the bill. To ensure you enjoy your experience to the full, we’ve focused on maximum comfort and carefully considered features. Adjustable back systems create a tailored fit and make it easier and more comfortable to carry heavier loads for longer periods of time. Check out our trekking backpack models that cover a range of uses:
Correct way to wear a backpack
It's in the back system adjustment
With loads of 10 kg+ or when walking longer distances, ensuring the back system is correctly adjusted to your size is critical to carrying comfort. That’s why we equip all 35 liters+ backpack models with a back length adjustment system. With smaller packs, doing away with adjustable back lengths keeps the overall weight down. In such cases, back panel length can be determined by selecting a men’s/ regular (REG), women’s (SL,) or extra long (EL) model. Our backpacks are designed with an average athletic person’s proportions in mind.
Varislide system
Precision-adjustable back length for a perfect fit on any back length.
- Lift the plastic buckle at the center of the back panel.
- At the same time, either raise or lower the shoulder strap harness to the desired position.

VariQuick system
On backpacks featuring the VariQuick system, follow these steps when adjusting the back length:
- Pull back the hook & loop flap on the back panel.
- Thread the end of the strap through the desired loop in an upward direction, pull tight and fasten again.

Clip & Loop system
For our ultra-light trekking backpacks, we use a Clip & Loop system to adjust the back length for tailored comfort. Simply clip the carabiners into the loops at the desired height.
| Loop | 1 | 2 | 3 |
|---|---|---|---|
| Men's back length | 44 cm | 46 cm | 48 cm |
| Women's (SL) back length | 40 cm | 42 cm | 44 cm |

How to pack a trekking backpack

Aside from selecting the right type of backpack, using it the right way is also important in achieving the best carrying comfort. This includes packing it correctly, and for models with an adjustable back system, adjusting it precisely. The main aim when packing your backpack is to do away with any unnecessary items.
The heaviest part of the load should be close to the body and ideally at shoulder height. That way, the load’s center of gravity and your own center of gravity will be aligned, and the pack will not pull you backwards.
How heavy should a trekking backpack be?
What do these "trekking load categories" within our trekking backpacks mean?
With our load categories, we don’t mean the maximum load our trekking backpacks can take – they can handle way more than anyone would want to carry. They are intended as a guideline. It’s all about carrying comfort. The categories are decided based on a combination of the following:
- Build and sturdiness of the back system
- Expected carrying duration, e.g., trekking backpack compared to travel backpack
- Personal requirements, e.g., thru-hikers will want the lightest backpack possible, trekkers will place emphasis on comfort
- Individual fitness levels, e.g., the aspirations of an expedition team member will be greater than a hobby hiker’s
- They are also based on the usual or appropriate equipment required for that activity
Our load categories are only intended as a guide to help find the right trekking backpack. We would always recommend that customers test out carrying a backpack with a realistic load before buying.
“Recommended load up to”
These are not the maximum weight that can be carried in a particular backpack, but instead the load that is most common for that particular application. It is the weight that can be carried in comfort over several hours in a particular backpack model, when correctly fitted. When selecting a backpack model, in addition to load weight, the anticipated carrying duration and target group-specific requirements for carrying comfort are also taken into account. So, the ‘recommended load’ figures serve as an aid in finding the right backpack.
Packing lists: what you need to take on a trek
In general, for any trek:
Take only what you need – and nothing you don’t need! Together with state certified mountain guides from the German Association of Mountain and Ski Guides, we’ve compiled packing lists and some well-earned top tips. Please note that all weights are only intended as a guide and may vary. As a general rule, the higher quality the equipment, the more lightweight it will be. Have fun on your adventures!
