A 15.6-inch laptop backpack may seem straightforward to choose on paper. However, not every model with this label will fit every laptop. A 15.6-inch screen reveals little about the device’s overall dimensions. A slim laptop, charger, lunchbox and documents can also take up more space than expected.
For students, school pupils, professionals and commuters, three things are particularly important: a suitable laptop compartment, protection from rain and a layout that suits your everyday needs. Below, you’ll find what to look out for and which models are suitable for different situations.
The screen size is measured diagonally. The laptop casing can vary depending on the bezels, keyboard and construction. So measure the height, width and thickness of your laptop and compare these measurements with the internal dimensions of the laptop compartment.
A backpack may be described as suitable for 15.6 inches, yet still be a tight fit for a business laptop with a wider casing. Also check whether there is enough room for a protective sleeve.
Many product titles use terms such as waterproof, water resistant or anti-splash. In practice, this may mean that the fabric helps repel splashes or a brief shower. It does not automatically mean that the seams, zips and laptop compartments will remain watertight for a long time.
If you cycle every day in the Netherlands, it’s better to look for:
According to Beneunder’s product description, the fabric used is resistant to wind, rain and stains. This is a product specification from the brand; it is not a guarantee that the contents will stay dry in all weather conditions.
A backpack with multiple compartments can help keep everything organised, but only if the compartments are large enough for your belongings. Pay attention to the position of the laptop compartment, the space available for a charger and how easily you can access smaller accessories.
A business model with a laptop compartment, document compartment and space for a water bottle works differently from a travel backpack with a laptop compartment that also needs to hold clothing and toiletries. A large capacity is not always useful if you mainly travel light.
A suitable laptop compartment should hold your laptop reasonably securely. Too much room for movement can cause the device to shift against the side of the bag as you walk. Soft lining helps reduce scratches, but a backpack is not a hard protective case.
Also check whether:
For commuting, a capacity of around 10 to 20 litres is often enough for a laptop, charger, documents and a few personal items. If you carry sportswear, lunch and extra clothing, you’ll probably need a spacious laptop backpack of 20 to 30 litres.
An expandable backpack offers flexibility. Do pay attention to the dimensions when the bag is expanded, though. Extra capacity can be useful for a short trip, but it also makes the bag fuller and potentially heavier on your back.
A lightweight bag helps keep the overall weight down, but also consider the shoulder straps and back panel. Wide, adjustable straps distribute pressure more effectively. A chest strap can be useful when cycling, walking or carrying a full bag.
Place heavy items as close to your back as possible. This is generally more stable than keeping the charger, books and water bottle all at the outer edge of the bag.
Why it suits this profile: This compact backpack is designed for everyday use, short journeys and light luggage. Do check your laptop’s dimensions before buying, as the product information does not state a maximum screen size for the laptop compartment.
The capacity is clearly specified as 10 litres, expanding to 13 litres. This gives you a better idea in advance of how much luggage will fit than an unclear marketing claim would.
Lightweight at 8.3 oz, with expandable capacity and nylon fabric that, according to the product description, helps resist wind, rain and stains.
Why it suits this profile: This model is ideal for professionals and travellers looking for a business backpack with room for equipment, clothing and everyday essentials.
The capacity is clearly stated as 25 litres, expandable to 30 litres. The compartments and maximum laptop size of 15.6 inches are also specified.
25 to 30 litres of capacity, chest straps, lockable zips and a hidden RFID-blocking compartment, according to the product description.
Why it suits this profile: A practical choice for travellers, weekend users and commuters who want a travel backpack with a laptop compartment and variable capacity.
The capacity is not merely described as “large capacity”; it is stated as 25 litres and expandable to 35 litres. For air travel, do check your airline’s rules in advance.
Expandable capacity from 25 to 35 litres, multiple compartments and a design described as water-repellent in the product title.
For models with an external USB port, check whether the bag only provides a cable pass-through or also includes a power bank. A power bank is often not included. Also keep electronics away from moisture, even when the outer fabric is water-repellent.
We’ve put together a complete, up-to-date list of products that fully meet these strict selection criteria and the applicable European safety regulations.
No, not always. Measure the laptop itself and compare its dimensions with those of the compartment. Also consider the laptop’s thickness and whether you use a protective sleeve.
For just a laptop, charger and documents, around 10 to 20 litres is often enough. For sportswear, lunch or a short overnight stay, 25 litres or more is more practical. An expandable model gives you extra flexibility.
Follow the manufacturer’s instructions. For example, Beneunder LC183’s instructions state that you can wipe the outside with a damp cloth and leave the bag to air-dry. Avoid using a washing machine or exposing the bag to prolonged direct heat unless permitted.
