Choosing a 15.6-inch laptop backpack: practical buying tips and suitable models

A 15.6-inch laptop backpack may seem easy to choose at first glance. In everyday use, however, you only find out whether the laptop compartment fits properly, the bag is comfortable to carry and there is enough room left for the charger, documents and other belongings. For students, professionals, business travellers and commuters, three pitfalls are particularly important.

The first is a laptop compartment that is too tight. A screen size of 15.6 inches only tells you the diagonal measurement. Laptop bodies vary from one make and model to another. A 15.6-inch laptop will therefore not automatically fit every compartment with the same label.

The second pitfall is mistaking a water-repellent laptop backpack for a completely waterproof bag. According to the product description, some models can repel water, but that does not mean the zips and seams will withstand heavy rain for a long time. In bad weather, consider using a separate rain cover.

The third pitfall is an overfilled backpack with little practical organisation. Lots of compartments may sound appealing, but small sections can actually take up valuable space. Think about what you carry every day: laptop, adapter, lunch, headphones, A4 documents and perhaps enough clothing for one night.

Which specifications should you check before buying?

1. Laptop compartment and internal space

Measure your laptop’s width, depth and thickness. Compare these measurements with the dimensions of the laptop compartment listed in the product information. Also check the fastening: an elastic strap, zip or padded compartment can make a difference when carrying the bag on a train or in a bicycle basket.

A laptop backpack for men and women does not need to be large, but it should leave some room around the laptop. A compartment that is too tight can put strain on the zip and leaves little space for a protective sleeve.

2. Capacity and intended use

For everyday commuting, a capacity of around 18 to 25 litres is often practical. If you also carry sportswear, documents or belongings for a short trip, a spacious backpack or expandable backpack may be a better choice.

The first model below lists an expandable capacity from 25 to 35 litres. When using it as cabin baggage, always check your carrier’s dimensions and conditions; the product name alone does not guarantee that the bag will be accepted as cabin baggage by every airline.

3. Material, zips and additional features

Check whether the product description refers to the bag as water-repellent, waterrepellent or waterproof. According to the brand’s or seller’s own product information, these are properties of the model offered; the actual level of protection also depends on rainfall intensity, duration of use and the condition of the zips.

A business backpack often has a practical, understated design and several compartments for accessories. A backpack with a USB charging port can be useful when you are out and about, but check whether it is only an external port. In most cases, you will need to connect your own power bank; a power bank is not automatically included.

Frequently asked questions about 15.6-inch laptop backpacks

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

No. The designation usually refers to the screen diagonal, not the full laptop body. Measure your laptop and compare its dimensions with those of the laptop compartment. Leave extra room for a sleeve or adapter.

How long does a laptop backpack typically last?

Its lifespan depends on the load, material, zip quality and frequency of use. A bag that is filled heavily every day will wear out faster than one used mainly for commuting. Check the seams, shoulder straps and zips regularly, and avoid overloading the bag for extended periods.

Is a USB charging port enough to charge a laptop?

Usually not. On a backpack with a USB charging port, this is generally a pass-through connection that allows you to connect your own power bank on the outside. You will need to check the power bank, cable and suitable charging capacity separately. A laptop will also often require a more powerful charger than a smartphone.
