A 15.6-inch laptop backpack may seem straightforward to choose at first glance. However, two bags designed for the same laptop size can differ considerably in layout, protection and everyday practicality. A laptop compartment that is too tight, insufficient space for accessories or material that only copes with a few splashes can quickly lead to disappointment.
For students, pupils, commuters and business users, three pitfalls are particularly important:
As well as checking the 15.6-inch designation, measure your laptop. The screen size refers to the screen’s diagonal, not the device’s total width, depth and thickness.
Pay attention to the following points:
A backpack for a laptop and work essentials should not only fit everything you need; it should also be easy to organise. For everyday commuting, a slim business backpack is often sufficient. For studying, travelling or longer days, a spacious laptop backpack is more practical.
Product descriptions use terms such as “water resistant” and “water repellent”. In practice, these labels usually mean that the material helps repel moisture temporarily. They do not automatically say anything about the seams, zips or the level of protection during a heavy shower.
Therefore, check:
Without a verifiable standard or measurement, it is best to view water-repellent as a practical feature for light rain, rather than as complete waterproofing. If you often cycle or walk outdoors, you may also want to consider a separate rain cover.
An expandable backpack can be useful when you carry more items on certain days. A model that can, for example, expand from 25 litres to 35 litres, offers greater flexibility for clothing, documents or travel essentials. Bear in mind, however, that more capacity can also mean more weight.
A laptop backpack with a USB port can be handy when you are out and about. Usually, this is an external connection that lets you connect a power bank stored in an internal compartment. The backpack does not charge your phone independently. Check whether the required power bank and cable are included; if this is not clearly stated, do not assume that they are.
For travelling, a luggage strap, wide opening and sturdy handle are useful details. For work and study, a separate laptop compartment, document pocket and quick access to smaller accessories are often more important.

Use this quick checklist before ordering a laptop backpack:

No. The screen diagonal is only one indication. Compare your laptop’s width, depth and thickness with the internal dimensions of the protective compartment. Also allow room for a sleeve or charger.
That depends on the duration and intensity of the rain. Water-repellent material helps in light rain, but does not guarantee protection against water getting inside. For regular cycling, a rain cover is a sensible addition.
A medium-sized bag may be enough for a laptop, charger and a few everyday items. If you also carry sportswear, documents or travel essentials, an expandable backpack is a better choice. Do not look only at the maximum capacity; consider the layout and carrying weight too.
