Choosing a 15.6-inch laptop backpack: look out for these pitfalls and smart features

A 15.6-inch laptop backpack needs to do more than simply carry a laptop. Students often take books and a charger with them, commuters have to deal with rain and crowded trains, while travellers want to carry extra clothing and documents. Yet many models look much the same at first glance.

That is why you should pay particular attention to three common purchasing pitfalls:

  1. Confusing “waterproof” with water-repellent
    A product title may use terms such as waterproof or water resistant, but that does not automatically mean the bag can withstand heavy rain for extended periods. Check whether the material, seams and zips are actually described as water-resistant. A water-repellent backpack is generally suitable for light rain, but a separate rain cover may be a sensible choice if you cycle every day.

  2. Looking only at the screen size
    A laptop with a 15.6-inch screen does not always have the same external dimensions. A thick work laptop, gaming laptop or laptop with wide screen bezels may be larger than the laptop compartment. Measure the laptop itself and compare its dimensions with those of the stated compartment.

  3. Confusing plenty of capacity with good carrying comfort
    A spacious laptop backpack can be useful, but a full bag quickly becomes heavy. Look for padded shoulder straps, a firm back panel and, where appropriate, a chest strap. A larger capacity, such as that offered by a 25-litre backpack, is particularly useful when you regularly make use of the extra space.

Which specifications are important?

1. Laptop compartment and internal dimensions

Look for a separate, well-fitting laptop compartment. This helps prevent the laptop from moving around loose among books, cables and other belongings. Also check:

  • the maximum screen size, for example 15.6 inches or 39.6 cm;
  • the internal width and height of the compartment;
  • whether the bottom is padded;
  • whether the laptop is secured with a zip, hook-and-loop fastening or elastic strap.

A laptop backpack for work and school often benefits more from a well-fitting compartment and an organised layout than from an exceptionally large main compartment.

2. Material and protection from rain

Polyester and canvas are commonly used for laptop backpacks. The product description should make it clear whether the material is described as water-repellent, water-resistant or waterproof. These terms are not automatically interchangeable.

Pay attention to the fastening as well. A roll-top or flip-top design can partially shield the opening, but the level of protection also depends on the construction and seams. When cycling in changeable weather, do not carry electronic devices without additional protection unless the manufacturer provides clear information to the contrary.

3. Capacity, compartments and extra features

Think in advance about what you need to carry every day:

  • laptop and charger;
  • A4 documents or books;
  • lunch and water bottle;
  • clothing for a short trip;
  • power bank, mouse and cables.

An expandable backpack can stay compact on working days and offer extra space when travelling. With a model that expands from 25 to 30 or 35 litres, however, you should allow for additional weight when using the expanded capacity.

A backpack with a USB port can be practical for connecting a power bank. The port does not charge devices by itself: you need a suitable power bank and cable. Also check whether the power bank fits in a separate compartment.

RFID protection is a specific feature that is not included in every business backpack. According to HP’s product information, the HP Travel model has a concealed RFID-blocking compartment. This is an HP product specification; the feature should not be presented as a guarantee against every form of data theft.

When are other designs worth considering?

For cyclists and urban commuters, a roll-top laptop backpack can be practical because the top closes flexibly. The Water Repellent Roll Top Laptop Backpack is described as a water-repellent model for work, cycling and urban travel. If you prefer a more classic look, consider the 15.6-inch vintage canvas backpack. Canvas can suit a casual style, but here too, check the fastening and protection from rain.

A model with an external USB charging port, such as the Expandable Business Travel Backpack, is particularly useful if you want to use a power bank while on the move. For a business backpack, a trolley strap, document compartment and lockable compartments are also useful features to check.

Frequently asked questions about a 15.6-inch laptop backpack

Will every 15.6-inch laptop fit in a 15.6-inch laptop backpack?

No, not automatically. The inch measurement refers to the screen diagonal, not the laptop’s overall dimensions. Measure the laptop and compare its width, height and thickness with those of the laptop compartment.

How long does a laptop backpack typically last?

Its lifespan depends on the load, materials, zips and frequency of use. A bag that is constantly overloaded will wear out more quickly. Distribute the weight evenly, place heavy items close to your back and only use the expansion zip when necessary.

Is a water-repellent backpack sufficient for cycling in the Netherlands?

A water-repellent backpack may be sufficient for light rain, but it does not offer the same protection as full waterproofing. In prolonged or heavy rain, a rain cover is advisable. Also keep your laptop in its own compartment and avoid leaving zips open while cycling.
