Choosing a 15.6-inch laptop backpack: how to avoid a bad purchase

A 15.6-inch laptop backpack may seem easy to choose at first glance. However, not every model with this size label will actually fit every laptop properly. A lack of compartments, thin shoulder straps or an overly optimistic water-resistance claim can also make everyday use unnecessarily difficult.

For students, school pupils, professionals, commuters and travellers, these are the main pitfalls to watch out for:

  • Screen size is not the same as your laptop’s external dimensions. A 15.6-inch laptop may be larger than the laptop compartment because of a wide bezel or thick chassis.
  • Water-repellent does not mean waterproof. A coating can help repel light rain, but it does not guarantee protection during prolonged or heavy rainfall.
  • Lots of compartments do not automatically mean good organisation. Check whether there is a separate laptop compartment, room for the charger, and pockets for documents, a bottle and accessories.
  • A USB port does not charge devices by itself. With a laptop backpack featuring a USB port, you will generally need a power bank; the backpack acts as an external connection.

What should you look for in a 15.6-inch laptop backpack?

1. Check laptop compatibility

Do not just look for “15.6 inches”; compare your laptop’s dimensions with those of the laptop compartment. A suitable 15.6-inch laptop backpack should provide enough room without allowing the device to slide around.

Also look for:

  • a padded laptop compartment;
  • a fastening or strap to keep the laptop in place;
  • enough depth for a charger and, if necessary, a sleeve;
  • protection on the bottom and sides.

For example, the HP Prelude Pro 15.6-Inch Backpack lists a padded compartment for a 15.6-inch laptop. According to the product specifications, this bag measures 31,75 × 12,7 × 42,55 cm and has a stated weight of 480 grams.

2. Choose capacity based on what you carry every day

A school backpack often has different requirements from a work backpack. For books, lunch and sportswear, a capacity of around 20 to 30 litres is practical. If you only carry a laptop, charger and documents, a more compact model may be sufficient.

A roomy backpack with compartments is particularly useful when you want to keep your belongings separate. For example, look for:

  • a main compartment for clothing, books or documents;
  • a separate laptop or tablet compartment;
  • a front pocket for keys and your phone;
  • side pockets for a water bottle or umbrella;
  • an expandable compartment for extra luggage.

The HP Travel 25L has a capacity of 25 litres and, according to the product information, can be expanded to 30 litres. This makes this type of expandable backpack suitable for commuting, a day of study or a short trip.

3. Assess comfort and materials realistically

A laptop backpack is often worn for long periods at a time. Padded shoulder straps, a cushioned back panel and an adjustable chest strap can improve carrying comfort. Check that the straps are wide enough and are not merely thin decorative straps.

Also consider the material. Polyester and synthetic fabrics are common and often easy to clean. A model made from recycled polyester may suit your preferences, but in itself this says nothing about carrying comfort or durability.

When it comes to water resistance, the wording matters. “Water-repellent” or “water-resistant” does not automatically mean that the seams, zips and laptop compartment will remain completely dry for long periods. If you cycle in heavy rain, take a separate rain cover or protective cover with you.

Frequently asked questions about 15.6-inch laptop backpacks

Will every 15.6-inch laptop fit in the same backpack?

No. Screen size is only one measurement. Check the width, height and thickness of your laptop and compare them with the laptop compartment. Leave some extra room for a protective sleeve and charger.

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

For light rain, a water-repellent outer layer can help. In prolonged or heavy rain, it does not provide complete protection. Consider using a rain cover and placing your laptop in a separate protective sleeve as well.

How long will a laptop backpack last?

Its lifespan depends on the material, zips, seams, load and maintenance. Do not overload the bag, store sharp objects carefully and clean the material according to the instructions. When purchasing, also check the warranty and your statutory rights as a consumer.
