Choosing a backpack that suits school, work, sport and travel

A backpack seems simple: pick a model with enough pockets and you're done. In reality, most poor purchases come down to details that only become apparent after a few weeks. A laptop compartment turns out to be too small, the shoulder straps dig in, or the fabric can't handle a short downpour.

With this buying guide, you can compare key specifications and use cases. That way, you'll more easily find a laptop backpack, school backpack, work backpack or travel backpack that fits your daily routine.

Three common pitfalls when buying a backpack

1. Laptop sizes don't always match the product title

A label like "15.6-inch laptop backpack" usually refers to the maximum screen size, but laptops also have different bezels and casings. So don't just check the number of inches – also check the dimensions of the laptop compartment.

Also watch out for conflicting product information. With the NINETYGO backpack, the title mentions a laptop up to 15.6 inches, while the description states compatibility up to 14 inches. If you use a larger laptop, it's a good idea to compare the current product specifications with your device's dimensions before buying.

2. Water-repellent is not the same as waterproof

A water-repellent backpack can help fend off light rain and splashes. That doesn't automatically mean the contents will stay dry for long in a heavy shower. A roll-top closure or coated fabric can offer extra protection, but even then, careful closing is important.

In heavy rain, it's best to protect electronics with a separate cover. According to the product information for the NINETYGO, the fabric is water-repellent, but not fully waterproof and not intended for prolonged exposure to heavy rain.

3. Lots of capacity can affect carrying comfort

A spacious backpack is handy for books, clothes and accessories, but a large main compartment doesn't automatically make a bag comfortable. Look for adjustable, padded shoulder straps, a padded back panel and possibly a chest strap. Distribute heavy items close to your back and avoid regularly overloading the bag.

A handle is also practical when you need to lift the backpack briefly or carry it on public transport.

Key specifications to compare

Laptop compartment and dimensions

Measure your laptop: width, depth and thickness. A 15.6-inch model won't necessarily fit in every compartment with the same label. For a business laptop backpack, the overall external dimensions are also important. A bag measuring 30 × 43.5 × 18.5 cm, for example, takes up more space than a slim model.

If you travel daily with a laptop, charger and documents, you'll benefit from:

  • A separate, padded laptop compartment.
  • A sturdy zip.
  • Extra pockets for cables, phone and power bank.
  • A handle for an alternative carrying method.
  • A stable base when the bag is often set down.

Capacity and layout

Capacity is usually given in litres. A compact backpack is suitable for a laptop and a few accessories. For school, work and short trips, around 20 to 30 litres is often more practical, depending on what you take with you.

A spacious backpack with multiple compartments helps separate books, clothes and electronics. However, a bag that's too large can encourage overpacking. So don't just look at the number of pockets, but also their size and accessibility.

Material and daily maintenance

Nylon, polyester and synthetic fabrics vary between products in weave density, coating and finish. Kensington, for example, specifies 1680 denier nylon for the SP25. That's a verifiable material specification, but it doesn't on its own tell you how long a bag will last in your situation.

Also check the care instructions. Different models are designed to be cleaned with a damp cloth and should not be machine washed. Zips, buckles and seams deserve extra attention if you load the bag heavily every day.

Frequently asked questions about backpacks

Which backpack is suitable for a 15.6-inch laptop?

Choose a model whose laptop compartment is explicitly suitable for 15.6 inches and also check the internal dimensions. The Kensington SP25, HP Travel and Lenovo ThinkPad Professional all state laptop compatibility in this class. With the Lenovo, the information differs between the general description and the specifications, so check the exact size of your laptop before buying.

How long does a backpack typically last?

The lifespan depends on weight, frequency of use, rain and maintenance. A bag that's heavily loaded every day will wear out faster at the base, zips and shoulder straps. Clean the backpack according to the instructions, don't overload it and store it in a dry place. A material specification such as nylon or 900D fabric helps with comparison, but doesn't guarantee a fixed lifespan.

What should I look for in a comfortable backpack?

Look for adjustable and padded shoulder straps, a padded back panel and good weight distribution. For longer cycle rides or trips, a chest strap can provide extra stability. Adjust the straps so the backpack sits close to your back and place heavy items low and central. That way, you'll make the most of the carrying comfort, whether you choose a backpack for women and men, a school backpack or a business laptop backpack.
