Choosing a 15.6-inch laptop backpack: how to avoid a poor choice for work, school or travel

A 15.6-inch laptop backpack may seem straightforward to choose at first glance. However, not every model with “15.6 inch” in the title will actually fit every laptop of that size properly. Spacious compartments, water-repellent fabric and a USB charging port can also work differently in practice from what the product name suggests.

So pay particular attention to these three common pitfalls:

1. The laptop size is not checked properly. A 15.6-inch screen size does not tell you everything about your laptop’s width, thickness and corners. A sturdy gaming laptop may be larger than a slim office or school model.
2. Water-repellent is confused with waterproof. A water-repellent laptop backpack offers extra protection from light rain, but seams, zips and openings remain vulnerable points.
3. Lots of compartments do not automatically mean a good layout. A backpack may look spacious but still be awkward to use if the laptop compartment is too tight or documents become creased among other belongings.

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

1. Check the internal dimensions, not just the product title

Measure your laptop before ordering: width, height and thickness. Compare these measurements with the dimensions of the laptop compartment. A sleeve or protective case can add a few extra centimetres.

Also look out for conflicting product information. The NINETYGO College-Style Dual-Shoulder Backpack title states that it supports laptops up to 15.6 inches, while the product specifications mention compatibility up to 14 inches. If you have a genuine 15.6-inch laptop, it is sensible to check this information on the product page before ordering.

2. Consider the material and water protection

A water-repellent laptop backpack is practical for cycling, train journeys and walks to school or the office. Look for a clear material description, such as a sturdy synthetic fabric or a coating. However, “water-resistant” and “water-repellent” do not mean that your bag will remain completely dry during prolonged heavy rain.

A backpack made from 900D tear-resistant material, as stated for the NINETYGO model, may be more robust on paper than a thin polyester bag. According to the product description, this model has a level 4 water-repellent rating. At the same time, the manufacturer warns that the fabric is not fully waterproof and that prolonged exposure to heavy rain should be avoided. If you cycle every day in poor weather, consider using a separate rain cover.

3. Assess carrying comfort and organisation

For commuting and a full day at school, padded shoulder straps, a breathable back panel and a sturdy handle are important. A spacious laptop backpack should not only hold plenty, but also keep everything organised.

Useful features include:

• a separate padded laptop compartment;
• an A4 or document compartment;
• a front pocket for your phone, keys and power bank;
• side pockets for a water bottle or umbrella;
• a luggage strap for attaching it to a trolley;
• a lunch compartment if you want to keep food separate from electronics.

A multi-compartment backpack helps you organise accessories, but check that the compartments are large enough for your charger, mouse and documents. A backpack with a USB charging port usually contains only a pass-through or connection. You will still need your own power bank; the backpack will not charge your phone by itself.

Tips for extending its lifespan

Always put your laptop in the designated compartment and position the charger so that it does not press against the computer. Do not overfill the backpack: too much strain puts pressure on the zips, seams and shoulder straps. It is best to clean a water-repellent bag with a damp cloth. Hand washing and air drying are recommended for the NINETYGO model; machine washing and tumble drying are not advised.

For a lightweight laptop backpack, it is useful to compare its empty weight with its capacity. A larger bag weighing just over one kilogram may be comfortable thanks to its layout, but can feel heavy when filled to capacity every day. Travellers may also want to look for a trolley strap and a compartment that opens fully, as found on some travel backpacks with laptop compartments.

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 screen size is only one indication. Measure the entire laptop and compare it with the internal dimensions of the laptop compartment. Also take a protective case into account.

Is a water-repellent laptop backpack enough for cycling in the rain?

Water-repellent fabric can be useful in light rain. In prolonged or heavy rain, additional protection is advisable, such as a rain cover. Pay particular attention to zips, seams and openings, as water can enter through these areas.

Is a USB charging port really necessary?

That depends on how you use it. The port allows you to connect a power bank inside the bag to a cable on the outside. You will not need to open the backpack to connect your phone. The power bank itself is usually not included and must be charged separately.
