Choosing a 15.6-inch laptop backpack: practical buying tips and popular options

A 15.6-inch laptop backpack needs to do more than simply carry a laptop. For many people in the Netherlands, the bag comes along every day on the train, on a bike, to school or to the office. It often needs to hold documents, lunch, chargers and personal belongings too. Yet many models look much the same at first glance. That is precisely where disappointing purchases can happen.

Three common pitfalls when choosing a laptop backpack

1. “Suitable for 15.6 inches” does not always mean the same thing

A laptop’s screen size does not tell you everything about its external dimensions. A business laptop with a wide bezel, robust casing or extra-large battery may fit more tightly than expected. So do not just check the stated inch size. Also look at:

  • the dimensions of the laptop compartment;
  • whether the compartment is padded;
  • whether the laptop can be put in and taken out without much pressure;
  • how much space is left around the laptop.

A laptop compartment that fits closely can help prevent the laptop from moving around. A compartment that is too tight can put strain on the zip or seams.

2. Water-repellent is not the same as waterproof

A water-repellent laptop backpack helps protect against light rain or splashes. That does not automatically mean the contents will stay dry during a heavy shower. Pay attention to the product description, the fastening and the positioning of the zips. A roll-top or flap can provide extra cover for the opening, but always check that the laptop itself is stored in a separate protected compartment.

If you regularly spend a long time in the rain, consider using a separate rain cover. If you cycle every day, do not rely solely on terms such as “water resistant” or “water repellent”.

3. A USB port does not charge devices by itself

On a laptop backpack with a USB port, the connection is usually intended to link a power bank inside the bag to your smartphone using a cable. The backpack generally does not contain a battery. Check that there is enough space inside for your power bank and that your own cable is compatible. A USB port is particularly useful when you are out and about, but it is not a replacement for a good charger.

What to look for before buying

Laptop protection and compartment layout

For work or school, a separate padded laptop compartment is more important than a large main compartment with no organisation. Also look for room for A4 documents, a diary, mouse, adapter and cables. A business laptop backpack often has several smaller compartments, whereas a casual model may instead have one spacious compartment.

Think about what you carry every day. A bag with lots of compartments keeps small accessories organised, but can be inconvenient if you regularly pack larger items.

Capacity and expandability

A capacity of around 20 to 25 litres is often suitable for a laptop, documents and a few everyday essentials. If you also carry sportswear, lunch or travel items, it may be better to look for a spacious laptop backpack. An expandable laptop backpack provides extra capacity when needed, without requiring you to carry a completely full bag every day.

Do bear the weight in mind. A larger bag made with more material and extra zips can feel heavier, even when empty.

Carrying comfort for commuting

For a laptop backpack for work, school or travel, wide, adjustable shoulder straps are useful. A breathable back panel can feel more comfortable during longer walks or a cycle ride. A chest strap is handy when the bag moves around frequently, but not every model has one.

A laptop backpack for women and men does not need to be designed specifically for one particular group. More important are the length of the shoulder straps, the back length and how the weight is distributed.

Useful travel features

If you regularly travel by train, bus or plane, look for a laptop backpack with a luggage strap. This allows you to attach the bag to the handle of a wheeled suitcase. A wide opening is useful at security checks and when packing. For everyday use, a simple zip may be quicker than a complicated fastening.

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 always. Screen size is only one indication. Measure the length, width and thickness of your laptop and compare these with the dimensions of the laptop compartment. Also allow for a protective sleeve.

How long does a laptop backpack last?

Its lifespan depends on the weight carried each day, use in the rain, the quality of the zips and how the bag is put down. Avoid overloading it and regularly check the seams, shoulder straps and zips. A bag with a sturdy laptop compartment will not automatically last longer if the rest of its construction is subjected to heavy strain.

Does a laptop backpack with a USB port use extra power?

The USB connection itself uses no power when no power bank is connected. The power comes from your own power bank. The battery life therefore depends on the capacity of that power bank and the device you are charging with it.
