A 15.6-inch laptop backpack needs to do more than simply carry a computer. Students often pack books and accessories, commuters want room for lunch, and office workers are looking for a professional backpack that remains practical on the train or bicycle. However, a backpack can look more spacious, sturdier or better protected in product photos than it is in everyday use.
So before you buy, pay particular attention to the following potential pitfalls.
Many models are described as water-repellent or water-resistant. This generally means that light rain temporarily beads off the material. It does not guarantee that the bag will withstand prolonged rain, puddles or a completely wet bike ride. So check whether the product description refers to water-repellent material and, in changeable weather, consider using a separate rain cover.
A laptop’s screen size does not tell you everything about its external dimensions. A thick model, gaming laptop or laptop with a wide bezel may need more room than a slim office device. So do not just look for “15.6 inches”; also check the shape of the laptop compartment, the padding and the space available for the charger.
A 15.6-inch laptop backpack with a separate, padded compartment generally offers better organisation than a large main compartment where the computer slides around between books and other belongings.
A laptop backpack with a USB port usually has a pass-through or connection on the outside. You will generally still need your own power bank for charging. The USB port is not a built-in battery. A luggage strap is only useful if it is sturdy enough and fits your trolley case.
Also pay attention to the zips, handles and shoulder straps. A spacious laptop backpack that is heavily loaded requires well-adjustable straps and a back panel that sits comfortably against your back.
For everyday use, the external dimensions are at least as important as the laptop size. A bag measuring approximately 48 x 33 x 21.5 cm provides room for more than a laptop, but it also takes up more space under a desk or on a crowded train. Think in advance about what you carry every day:
A backpack with multiple compartments helps keep small accessories separate. An A4 organiser compartment is particularly useful for documents that must not get creased.
A padded laptop compartment protects against minor knocks, but it does not replace a hard protective case. Check that the compartment closes securely and that the laptop does not rest directly on the bottom. With a water-repellent laptop backpack, it is sensible not to treat the bag as completely waterproof.
Canvas, synthetic fabric and leather-look materials can each create a different appearance. Check the product description for the exact material specification. Claims about durability or protection come from the brand’s or seller’s product information and should not be taken as a guarantee of years of use.
An empty backpack weighing 1.14 kg can be comfortable when you need a lunch compartment and extra pockets, but it will feel heavier once you add a laptop, books and accessories. For a commuting backpack, a breathable back panel, wide shoulder straps and several carrying options are useful features.
If you cycle frequently, also look for a stable fit. When travelling, a luggage strap is useful for attaching the bag to a wheeled suitcase. If you often walk through busy stations, you may instead appreciate a zipped pocket that sits close against your back.

Not always. The stated size usually refers to the maximum screen size, not the device’s exact external dimensions. So compare your laptop’s measurements with the internal compartment and allow for a protective case.
Choose a model whose product description mentions water-repellent material and make sure all compartments are properly closed. In prolonged or heavy rain, a rain cover is a sensible addition. You should also avoid placing a laptop loose against the outer wall of the bag.
The USB port generally works as a connection between a power bank inside the bag and your cable on the outside. A power bank is not automatically included. Always check the contents of the product and use a suitable cable for your phone or other device.
