How to buy a backpack: choosing a practical model for school, work or everyday use

A backpack might seem simple to choose, until you use it every day. A main compartment that’s too small, shoulder straps that rub, or a zip that’s awkward to open – you only notice these things once the bag is in use. Marketing terms like “durable”, “laptop-ready” or “ergonomic” also tell you very little when concrete dimensions, materials and compartment layouts are missing.

So pay particular attention to these three common pitfalls:

  • The wrong size: a backpack can look roomy in a photo, but in practice may not have enough space for a lunchbox, sports kit or laptop.
  • An awkward layout: without a backpack with a front pocket, keys, phone and bike light often end up at the bottom of the main compartment.
  • Comfort that doesn’t match the load: adjustable straps are useful, but also check whether they are padded and whether the back panel offers enough support.

Which specifications matter?

1. Size and capacity

Don’t just look at the dimensions – also look at the capacity in litres. A compact children’s backpack is suitable for small items and a light school day. For sports kit or a work day, you’ll need more capacity.

As a guide:

  • Up to around 13 litres: suitable for young children, short trips or a light school day.
  • Around 20 to 25 litres: practical for older children, teenagers, work and sport.
  • Larger models: handy for travel or when you’re taking extra clothes and accessories.

Also check the size of the main compartment. A school backpack with a two-way zip is often easier to open fully than a bag with a narrow top opening.

2. Compartment layout and access

A backpack with a front pocket makes small items accessible without having to empty the main compartment. A mesh side pocket can be suitable for a water bottle, while an internal tech compartment is intended for a laptop or tablet.

Pay attention to the wording in the product information. “Suitable for laptop” is not the same as a protective laptop compartment with a stated size. If you’re looking for a laptop backpack, it’s a good idea to compare the dimensions of your device with the available space.

3. Material, straps and care

Polyester, coated canvas and material with a polyurethane coating are common for backpacks. Check whether the bag can be cleaned with a damp cloth and whether wet items need to be removed immediately. This prevents unnecessary wear to the lining.

For everyday use, adjustable shoulder straps are important. Padded straps and a padded back panel can improve carrying comfort, but the experience varies from person to person and depends on the load. A reflective detail is practical for children who cycle to school or sport in the dark.

When it comes to claims about recycled materials, the product specification is the relevant source. For the PUMA models mentioned below, the product information states that at least 90% of the materials used are recycled. That is a product specification, not a guarantee about the total environmental impact of the bag.

Frequently asked questions about backpacks

What capacity does a school backpack need?

That depends on the child’s age, school supplies and activities. For a young pupil, around 10 to 15 litres may be enough. Older children and teenagers often need more space for books, lunch and sports kit. Always compare the dimensions with what needs to go in it every day.

How do I clean a backpack?

Follow the manufacturer’s care instructions. For the PUMA models mentioned, cleaning with a damp cloth is recommended and the use of detergent is advised against. Remove wet items immediately and let the bag dry completely before storing it.

Is a laptop backpack automatically suitable for every laptop?

No. Check the size of the internal tech compartment and compare it with the width, height and thickness of your laptop. A backpack with a tech compartment provides a space for a device, but doesn’t in itself tell you how much protection or padding is present.
