Buying a backpack: how to choose a practical model for school, work or travel

A backpack might seem simple to choose, until you realise day after day that the laptop compartment is too small, the contents are a jumble, or the shoulder straps are uncomfortable. Marketing terms like “water-repellent”, “spacious” and “durable” don’t always tell the full story either.

So before you buy, watch out for these common pitfalls:

  • Contents without a useful layout: a large main compartment isn’t automatically handy. Without separate pockets, your laptop, documents and accessories can all get mixed up.
  • Water-repellent is confused with waterproof: polyester or a coating can offer protection against light rain and splashes, but that doesn’t mean the backpack will keep out heavy rain for long.
  • Comfort is judged only from the photo: a padded back panel and adjustable straps are useful, but the fit, dimensions and maximum load also determine how comfortable a backpack is for daily use.
  • A laptop compartment without checking the size: always check the laptop size in inches and the dimensions of your device. A 14-inch laptop won’t automatically fit in every compartment labelled as a “laptop compartment”.

Which specifications matter?

1. Dimensions and capacity

For school, work and commuting, a capacity of around 20 to 27 litres is often practical. A 20-litre model is suitable for daily essentials and a tablet or small laptop. A roomy backpack of 24 to 27 litres offers more space for A4 documents, books, clothing or a lunchbox.

Alongside the litre capacity, pay attention to the external dimensions. A backpack that is 44 cm high may be suitable for A4 folders, but the depth determines how much space you actually have. A thick model can also be less comfortable on crowded public transport.

2. Laptop compartment and internal layout

A backpack with a laptop compartment is especially handy if you regularly travel to the office, school or university. Check:

  • the stated maximum laptop size;
  • whether the compartment is padded;
  • whether the compartment sits against your back;
  • whether there is room left for a charger and accessories;
  • whether documents can stay flat.

The Eastpak Out of Office Blue Medium and Grey Medium are listed in the product information with a padded laptop compartment for a laptop up to 13.3 inches and a capacity of 27 litres. Still check the dimensions of your own laptop before buying.

3. Material, carrying comfort and load

Many models in this selection use polyester or recycled polyester. That material is lightweight and suitable for daily use. A water-repellent backpack helps with light rain, but in bad weather it’s best to store electronics with extra protection.

Also look at:

  • padded shoulder straps that are adjustable;
  • a padded back panel;
  • a wide, stable base;
  • sturdy zips;
  • the maximum weight.

The Eastpak Pinnacle states a maximum recommended load of 10 kg. The Eastpak Out of Office Blue states 6 kg. So more capacity doesn’t mean you can fill the bag with unlimited weight.

Which backpack suits your use?

A school backpack mainly needs to carry books, A4 folders and daily items. For a work backpack, a laptop compartment and quick access to keys or your phone are often more important. You then choose a women’s backpack, men’s backpack or unisex backpack based on size, colour and fit; the practical features remain the deciding factor.

Frequently asked questions about backpacks

What capacity do I need for school or work?

For a laptop, lunch, charger and a few documents, 20 to 24 litres is often enough. If you also carry books, sports kit or extra items, it’s better to look at 24 to 27 litres. Always check the dimensions and maximum load.

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

A water-repellent backpack is mainly intended for light rain and splashes. The term doesn’t automatically mean the seams and zips are fully waterproof. For a laptop or tablet in prolonged rain, use a separate protective sleeve or choose a model with an additional rain cover.

How do I clean a backpack?

Follow the manufacturer’s care instructions. For many polyester models, wiping with a slightly damp cloth is sufficient. Not every model can go in the washing machine or be soaked. Keep the backpack away from direct heat and check that the zips dry properly after cleaning.
