A 15.6-inch laptop backpack may seem like a straightforward purchase at first glance. However, not every model bearing this label will fit every laptop properly. Terms such as “waterproof”, “business” and “large capacity” only mean something once you check how the bag is designed and what you intend to use it for.
For students, commuters and business users, these three pitfalls are particularly important:
A good choice therefore starts not with colour or style, but with dimensions, fastening, material and how you use the bag every day.
The 15.6-inch designation usually refers to the diagonal screen measurement. However, laptop exterior dimensions can vary. Measure your laptop’s width, depth and thickness. Leave extra room for a sleeve if you use one.
A laptop compartment should hold the computer reasonably securely in place. If the compartment is too spacious, the laptop may slide against the base or sides when you put the bag down. A compartment that is too tight makes packing and unpacking inconvenient every day.
With a spacious laptop backpack, also consider how the rest of the interior is arranged. A separate document compartment, accessory pocket and space for a bottle are often more useful in practice than one large main compartment alone.
A water-repellent backpack is generally made with a material or coating that allows water droplets to run off the surface temporarily. This is useful during a short cycle ride or walk to the station and office. However, the level of protection also depends on the seams, zips, flaps and condition of the material.
“Waterproof” has a stricter meaning in practice. Check whether the product information specifies a particular protection method or classification. Without this information, it is better to assume protection against light rain rather than prolonged immersion.
A waterproof laptop backpack is particularly relevant for cyclists and travellers who spend more time outdoors. Even with valuable electronics, use a protective sleeve and avoid leaving the bag wet for extended periods.
A backpack for commuting is often worn for several hours at a time. So check:
A flip-top or roll-top fastening can provide extra protection for the contents and makes the bag flexible to use. A zip fastening, on the other hand, offers quick access. A drawstring fastening is practical for a casual bag, but requires more attention when you often need to access your laptop or documents while travelling.
A business laptop backpack often has a understated appearance and a well-organised layout. For school or everyday city use, a more casual model may be a better fit. If you regularly travel by train, you may also want to look for a luggage strap for attaching the backpack to a trolley.
A laptop backpack with a USB port can be useful when you want to route a cable to an external power bank while on the move. The USB port itself is not a built-in battery. You will still need a suitable power bank. Also check that the cable and port are securely attached and that the connection is compatible with your devices.
An expandable laptop backpack is useful for travellers who take only a laptop one day and extra clothing or documents the next. Check whether expanding the bag makes it heavier or less stable.
For short trips, a travel backpack with a laptop compartment and several compartments can help keep electronics, clothing and accessories separate. For everyday use, a more compact layout is often sufficient. Carrying more items does not automatically mean greater comfort.

No, not automatically. Screen size is only one measurement. Compare your laptop’s width, depth and thickness with the internal dimensions of the compartment. Allow for a protective sleeve or additional accessories.
For short journeys and light rain, a water-repellent backpack can be practical. During prolonged or heavy rain, seams, zips and flaps do not always offer the same protection as a model specifically described as waterproof. Take additional protection for important electronics.
That depends on what you carry each day. A medium-sized bag may be sufficient for just a laptop, charger and documents. If you also carry books, sportswear or items for a short trip, a spacious or expandable laptop backpack is a better choice. Do bear the carrying weight in mind: more capacity can also mean a heavier bag sooner.
