How to choose a backpack without making a mistake: find the right model for school, work or travel

A backpack in the UK needs to stand up to daily use: cycling through a shower, hopping on and off the train, carrying a laptop, and sometimes stashing gym kit or groceries. Yet the choice can seem simpler than it really is. A backpack with lots of compartments isn’t automatically practical, and a model with a laptop sleeve won’t necessarily protect your computer from bumps or moisture.

The following points will help students, schoolchildren, commuters, professionals and travellers compare more effectively.

Three common pitfalls when buying a backpack

1. Only looking at capacity or size

A capacity of 20 or 25 litres doesn’t tell you everything. The shape of the main compartment, the opening and how the pockets are arranged determine how much you can actually carry. A narrow backpack might look roomy on paper, but becomes awkward as soon as you want to pack a lunchbox, jacket and laptop side by side.

So don’t just check the litre capacity – also look at:

  • the external dimensions;
  • the width of the laptop compartment;
  • the opening of the main compartment;
  • whether there are side pockets for a water bottle;
  • the space between your laptop, books and accessories.

2. Confusing “water-resistant” with waterproof

Terms like water-repellent and water-resistant don’t guarantee your belongings will stay dry in prolonged rain. With a water-repellent backpack, it’s usually the material or a finish that can help shrug off light drizzle. The zips, seams and openings remain weak points.

If you cycle every day, it’s worth checking whether:

  • the zips are covered;
  • the laptop can be placed in an extra sleeve;
  • the base is sturdy and well-sealed;
  • the product description clearly distinguishes between water-repellent and waterproof.

3. Judging comfort only after purchase

A heavily loaded backpack feels especially uncomfortable when the shoulder straps are narrow or the back panel offers little support. Look for padded shoulder straps, a cushioned back panel and, on larger models, a chest strap. A proper fit matters more than a flashy logo or a huge number of pockets.

Which specifications are important?

Laptop compartment and dimensions

For a 15.6-inch laptop backpack, don’t rely solely on the screen size. Laptops have different bezels and casings. Check the maximum compatible dimensions in centimetres when that information is available. The HP Travel 25L, for example, states support for a screen size of up to 39.6 cm (15.6 inches).

A laptop compartment is especially practical if the device doesn’t slide around loose against hard objects. For daily commuting, also take a protective sleeve if the product description doesn’t mention specific shock protection.

Capacity and layout

For a school backpack, a roomy main compartment and a separate section for smaller items are usually more useful than just one large space. For a work backpack, a laptop compartment, cable organiser and easy access also count.

As a rough guide:

  • 18 to 22 litres: suitable for everyday essentials, books or gym kit;
  • 24 to 25 litres: more room for a laptop, clothes, lunch and accessories;
  • 25 to 30 litres: interesting for short trips, thanks to an expandable design.

This breakdown isn’t a fixed rule. A backpack with a clever pocket layout can be more practical than a larger model without compartments.

Material, weight and carrying system

Polyester and recycled synthetic materials are common in everyday backpacks. Check whether the manufacturer states the material composition, and look closely at the seams, base and zips in product photos.

According to the product information, the PUMA Academy Backpack is made from at least 70% recycled materials and the Phase Backpack from at least 90% recycled materials. This is information from the brand’s product description and not a guarantee of a specific lifespan.

Also pay attention to the empty weight. A lightweight backpack leaves more room within your carrying limit, but a sturdier model may have a better-padded back panel or stronger zips.

Frequently asked questions about backpacks

Which backpack is suitable for a 15.6-inch laptop?

Choose a model whose product information explicitly states 15.6 inches or 39.6 cm. Also check the internal dimensions of the laptop compartment and use a protective sleeve if no shock protection is mentioned.

How long does a backpack typically last?

The lifespan depends on the load, material, seams, zips and usage conditions. A backpack that is heavily loaded every day will wear out faster than one used lightly. Distribute the weight, don’t overload the pockets and store the backpack in a dry place.

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

Not always. Water-repellent material is mainly intended for light drizzle. In prolonged rain, a rain cover and a separate laptop sleeve are sensible additions. Always check exactly what the manufacturer says about moisture resistance.
