Choosing a backpack without regret: consider size, material and intended use

A backpack may seem straightforward to choose at first glance. In practice, however, many models turn out to be less convenient than expected. A bag may look stylish but offer too little space for a laptop. A spacious travel backpack, on the other hand, can become uncomfortable when you carry it heavily every day. And material described as water-repellent is not automatically able to withstand a heavy downpour.

Use this practical checklist to compare a women’s backpack, men’s backpack or unisex backpack based on the features that matter in everyday use. You’ll then find a selection for school, work, sport, travel and everyday use.

Common pitfalls when buying a backpack

1. Looking only at the appearance

A black backpack, leather backpack or model with distinctive branding may go well with your clothes, but make sure you also check the layout. Without a separate compartment for a laptop, tablet or water bottle, the interior can quickly become disorganised.

Also pay attention to where the zips are positioned. A front pocket is handy for keys and your phone, while a main compartment with a wide opening works better for books, clothing or sports equipment.

2. Confusing capacity with carrying comfort

A capacity of 20 to 25 litres is suitable for many everyday situations, but carrying comfort does not depend solely on the number of litres. A padded back panel, adjustable shoulder straps and a good fit make a difference when you carry the backpack for longer periods.

With a large travel backpack, it is worth checking whether the model is already heavy when empty. A sturdy construction can be useful, but additional material increases the overall weight.

3. Interpreting “water-repellent” as waterproof

Polyester with a coating or water-repellent finish can provide protection against light rain. This does not automatically mean that the seams, zips and base are fully waterproof. If you cycle through the rain every day, it is sensible to use a rain cover or waterproof laptop sleeve if one is not included as standard.

The key specifications to check

Size and capacity

Choose the capacity based on what you actually carry:

  • 15 to 20 litres: suitable for a compact everyday bag, light commuting or a few school essentials.
  • 20 to 25 litres: practical for books, clothing, lunch and accessories.
  • 25 to 35 litres: ideal for travel, weekend use or a working day with extra belongings.
  • Around 45 litres: designed for larger quantities of clothing, sports equipment or longer trips.

Don’t just look at the capacity in litres; check the dimensions too. A backpack measuring 44 × 30 × 14 cm has a different shape when carried than a model measuring 48 × 35 × 24 cm, even when the capacity appears similar.

Compartments and equipment

A laptop backpack should not simply state a laptop size. Check whether the laptop compartment is padded, whether it holds the device securely and whether there is enough room left for a charger. With a 15.6-inch model, it is important to check the actual internal dimensions; screen sizes and laptop housings vary by brand.

For school or the office, a separate tech compartment, a zipped front pocket and smaller internal pockets are useful. For sport, a spacious main compartment with a double base may be a better fit. A sporty backpack is not automatically suitable for carrying a laptop.

Material, care and warranty

Polyester is lightweight, relatively easy to clean and often used for a school backpack, sports bag or everyday backpack. Leather has a different look, but requires more care and protection from moisture and heat. With faux leather or coated canvas, follow the brand’s care instructions.

The statutory guarantee in the European Union gives consumers rights when a product does not meet what can reasonably be expected. The precise assessment depends on factors including how the product was used, the product information and the nature of the problem. Keep your purchase details and check the terms before placing your order.

Frequently asked questions about backpacks

What capacity do I need for work or school?

For a typical working or school day, 20 to 25 litres is often a useful starting point. Add up your laptop, lunch, books, charger and, if applicable, sportswear. If you regularly carry extra shoes or clothing, look for a model with a capacity of 25 to 35 litres.

How long does a backpack typically last?

Its lifespan depends on the material, zips, seams, load and maintenance. A backpack that is filled heavily every day will wear out faster than a model intended for light use. Avoid overloading it, clean the material according to the instructions and regularly check the shoulder straps and zips.

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

Not always. Water-repellent material can temporarily keep out light rain, but it does not guarantee protection against prolonged rainfall or water entering through zips and seams. For cycling to work, a rain cover or separate protection for your laptop and documents is a sensible addition.
