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

A 15.6-inch laptop backpack may seem like a straightforward purchase at first glance. However, choosing the wrong one can quickly become inconvenient. For example, a laptop will not always fit in a compartment labelled “15.6 inches”. Thin shoulder straps, limited space for accessories or water-repellent fabric that is not waterproof can also make everyday use less comfortable.

For work, school, commuting and travel, these three pitfalls are particularly important:

  • Looking only at the screen size: laptops with the same screen size can have different external dimensions.
  • Confusing water-repellent with waterproof: a water-repellent laptop backpack does not automatically provide protection during prolonged or heavy rain.
  • Mistaking lots of compartments for sufficient space: a spacious laptop backpack should not only have compartments, but also suit what you actually carry.

Below, you’ll find out which specifications to check before buying a 15.6-inch laptop backpack.

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

1. Check the internal dimensions of the laptop compartment

The 15.6-inch designation usually refers to the diagonal screen size. The outside of your laptop may be larger because of the screen bezel, casing and construction. So measure your laptop:

  1. Width from left to right.
  2. Depth from front to back.
  3. Thickness, including any protective case.

Compare these measurements with the dimensions of the laptop compartment. A compartment suitable for up to 39.6 cm or 15.6 inches is not automatically suitable for every model. An overly tight fit can also make it more difficult to insert and remove the laptop.

A laptop backpack with a laptop compartment is preferable to a general main compartment. A padded or reinforced compartment keeps your laptop separate from books, chargers and other hard objects.

2. Consider the material and protection

Nylon, polyester and durable synthetic fabrics are common materials for everyday use. Don’t just look at the name of the fabric; also consider how the backpack is constructed:

  • Is the laptop compartment padded?
  • Are the base and seams finished securely?
  • Does the bag have a zip, roll-top closure or drawstring?
  • Is the back panel comfortably padded?
  • Are the shoulder straps adjustable and wide enough?

A water-repellent laptop backpack can help keep out light rain or splashes. This does not mean that the bag will remain completely dry during prolonged heavy rain. If you’re carrying a vulnerable laptop, consider taking a separate rain cover or protective case. According to the NINETYGO product information, the fabric is water-repellent but not fully waterproof; prolonged exposure to heavy rain is not recommended.

3. Match capacity and carrying comfort to your routine

If you only carry a laptop, charger and notebook, a slim business laptop backpack is often sufficient. If you also carry sportswear, lunch, books or travel accessories, a spacious laptop backpack is a better choice. In that case, look at the capacity and layout.

A capacity of 25 litres may be suitable for a working day. According to the product description, the HP Travel 25L can be expanded to 30 litres. Bear in mind, however, that a larger bag can become heavier and fuller. Distribute the load across several compartments and do not exceed the recommended capacity.

For cyclists and train commuters, a chest strap, trolley strap, easily accessible side pockets and a stable back construction are also practical features. A USB port is only useful if you also use a suitable power bank; the port itself does not charge a device.

Frequently asked questions about 15.6-inch laptop backpacks

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 width, depth and thickness of your laptop and compare these with the laptop compartment. Also take a protective case into account.

How long does a laptop backpack typically last?

Its lifespan depends on the material, zips, seams, load and conditions of use. A bag that is heavily filled every day will wear out faster than a backpack used for light commuting. Check the shoulder straps, base and zips regularly, and avoid overloading the bag.

According to the product information, products from brands including Kensington and HP come with a statutory guarantee of at least two years under European consumer regulations. This is separate from normal wear and tear or damage caused by incorrect use.

What does it cost to use a laptop backpack with a USB port?

A USB port on a laptop backpack generally acts as a pass-through connection to a power bank. The power bank is usually not included and must be charged separately. So check which accessories are included and whether the port is compatible with your cable. A model without a USB connection may be more practical if you don’t use this feature.
