A 15.6-inch laptop backpack may seem straightforward to choose at first glance. However, models can vary considerably in fit, layout and carrying comfort. A backpack may look spacious in the product photo but offer too little room in practice for a charger, lunchbox or documents. Terms such as “waterproof”, “business” and “USB charging” also do not always mean exactly what you need.
So pay particular attention to these common pitfalls:
Do not just look at the 15.6-inch designation. Measure your laptop:
A backpack with a laptop compartment should hold the device securely in place. If the compartment is too spacious, the laptop may shift while you are walking. A compartment that is too tight makes packing awkward and can put extra strain on the zip or seams.
Soft lining and a raised base are practical features. They can help prevent direct contact with the ground when you put the bag down. Do not consider this a guarantee against damage: careful use and a suitable case remain important.
For commuting with just a laptop, charger and a few documents, a compact backpack may be sufficient. If you also carry sportswear, lunch, headphones or travel essentials, a 25–35-litre laptop backpack is a better choice.
An expandable laptop backpack is useful when the amount you carry varies from day to day. In its compact configuration, the bag remains relatively slim; with the additional compartment opened, it provides more space for a weekend trip or business journey. Bear in mind, however, that a fully loaded bag will be heavier and may be less comfortable to carry.
Useful layouts include:
A water-repellent laptop backpack is practical for cycling, walking to the station and everyday use around town. Check whether the description says water-repellent, water-resistant or waterproof. These terms do not mean the same thing.
Also look for:
For a business backpack, a neutral shape is often practical in the office and during meetings. For school or travel, several easily accessible pockets may be more important than a formal appearance.

No, not automatically. The designation refers to the screen diagonal, while laptops with the same screen size can have different bezels and casing dimensions. Measure your laptop and compare its dimensions with the compartment specifications. Allow for a protective sleeve if you use one.
Its lifespan depends on the weight it carries, how it is used, exposure to moisture and the quality of the zips, seams and shoulder straps. A bag that is heavily loaded every day will wear out faster than one used for light commuting. Distribute the weight across several compartments, do not overload the zips and allow a wet bag to dry completely before storing it.
It can be useful when travelling or commuting, allowing you to connect a power bank. The USB port itself does not usually provide power. Check whether the bag has only a pass-through connection or whether a power bank is actually included. Also check that your cable and charging device are compatible.
A medium-sized model may be enough for a laptop, charger and documents. If you carry clothing, lunch and travel accessories, consider a 25–35-litre laptop backpack. An expandable model offers extra flexibility, but think beforehand about how often you will genuinely need the additional space. This will help prevent you from carrying an unnecessarily heavy large backpack for work and school every day.
