A 15.6-inch laptop backpack needs to do more than simply carry a laptop. In the UK, a backpack has to cope with rain, packed bicycle panniers, busy trains and being packed and unpacked every day. Yet many models disappoint in practice because of unclear dimensions, awkward compartments or materials that offer less protection than the product title suggests.
With this buying guide, you can compare the key features and find the right design for your needs – from a backpack for work and study to a spacious travel backpack for a short trip.
A water-repellent backpack can help keep light rain at bay, but that does not automatically mean the bag can withstand prolonged heavy rain or immersion. Check whether the product information refers to water repellent, water resistant or waterproof. These terms are not interchangeable.
Pay attention to the seams, zips and fastening too. Water-repellent material is of little use if rain gets in through an open top or a poorly covered zip.
A 15.6-inch laptop will not fit every bag labelled with that size. Screen sizes are measured diagonally, while a laptop compartment needs to accommodate the device’s actual width, height and sometimes thickness.
So check:
A spacious backpack can be useful, but a large main compartment without any organisation can quickly turn into a tangle of cables, books and personal belongings. For everyday use, several compartments, a separate laptop section and small zipped pockets are often more practical than a high litre capacity alone.
An expandable backpack is particularly useful when you carry fewer items on some days and more on others. However, check that the bag is still comfortable to carry when expanded.
Do not just look for the 15.6-inch designation; also consider the protection around the compartment. A padded section helps prevent the laptop from knocking directly against other belongings. For commuting, adjustable shoulder straps and a padded back panel are practical features.
A lightweight backpack can be comfortable for cyclists, students and commuters. Bear in mind that a lower empty weight does not always go hand in hand with strong structural protection. The balance between weight, carrying comfort and organisation is more important than any single specification.
When considering a waterproof laptop backpack, read the claim carefully. Products with “waterproof” in the title are positioned differently from models described as “water repellent” or “water resistant”. Treat a water-repellent backpack as protection against everyday rain unless the manufacturer provides specific additional information.
A brand’s own research may suggest that certain materials or constructions offer a particular level of protection. Do not treat such brand claims as a guarantee for every situation. Focus mainly on the product description, fastening and user experience.
For the office or studying, these features are generally useful:
A laptop backpack with a USB port generally has an external connection; the power bank and cable are not usually included automatically. So check exactly what is included in the product packaging.

No. The screen size alone does not tell you enough about the laptop’s external dimensions. Compare the width, height and thickness of your device with the dimensions of the laptop compartment. A small amount of extra room is practical, but too much space can allow the laptop to move around.
Its lifespan depends on the material, seams, zips, load and conditions of use. Cycling every day with a heavily loaded bag puts more strain on the construction than occasional use. Check the shoulder straps, base and zips regularly, and avoid overloading the backpack.
It can be useful if you use a power bank while travelling. The USB port allows you to route a cable to the outside, but it does not provide power itself. Before ordering, check whether the power bank, internal cable and any safety instructions are included.
