How to choose a backpack for school, work, sport or travel: what to look for

Choosing a backpack might seem simple, until you find yourself carrying a laptop, books, gym kit or travel essentials every day. A model that looks spacious in an online shop can turn out to have an impractical layout or offer insufficient support. Marketing terms like “ergonomic”, “durable” and “waterproof” don’t always tell the full story either.

With this practical checklist, you can compare backpacks based on the features that matter most to UK pupils, students, commuters, professionals and travellers.

Common pitfalls when buying a backpack

1. A large capacity isn't everything

A spacious backpack isn't automatically a practical one. A large main compartment with no dividers can cause your laptop, books and accessories to get jumbled up. That's why you should look beyond the capacity in litres and also check for:

  • A separate laptop sleeve or padded compartment.
  • Pockets for cables, pens and keys.
  • Side pockets for a water bottle.
  • An external zipped pocket for items you need to grab quickly.

A school backpack with space for A4 books can be more suitable for daily use than a bag with a larger, but poorly organised, main compartment.

2. ‘Water-repellent’ is often confused with waterproof

Water-repellent fabric can temporarily keep light rain at bay, but that doesn't mean the seams and zips will keep water out for long periods. Check if the product information specifically mentions a waterproof construction or a rain cover. If it doesn't, don't rely on the backpack for complete protection during prolonged rain.

For commuters who cycle, the placement of a laptop is also more important than the material alone. A laptop compartment positioned close to your back will generally stop the device from sliding around while you're walking or cycling.

3. Comfort claims are no substitute for a good fit

A backpack with padded shoulder straps can be more comfortable to carry, but the fit depends on the length of the straps, the size of the back panel and the weight you're carrying. A backpack that's too full will pull on your shoulders and can still feel uncomfortable. Look for adjustable straps, a padded back panel and a grab handle for short trips.

Key specifications to compare

Laptop size and internal dimensions

If you're looking for a backpack for a 15.6-inch laptop, don't just go by the stated screen size. Laptops with the same screen size can have different external dimensions. Measure your laptop, including any protective case, and compare those measurements with the laptop compartment.

The Kono backpack states it has a laptop compartment for up to 15.6 inches. The Lenovo ThinkPad Professional is linked in the product information to laptops up to 15 inches, while the specification table mentions a maximum screen size of 16 inches. For this model, you should always check your actual laptop dimensions before ordering.

Capacity, dimensions and carrying weight

A capacity of 22 to 24 litres is often suitable for school, work and daily use. For sport or a short trip, you might need more flexibility. Besides the capacity in litres, look at the overall dimensions:

  • The PUMA Phase has a capacity of 22 litres and measures 44 × 30 × 14 cm, according to the product information.
  • The PUMA Academy is listed with approximately 24 litres and dimensions of 45 × 30 × 18 cm.
  • The Kono backpack measures 48 × 30 × 17 cm and is designed for a laptop, A4 books and school supplies.

Also, pay attention to the weight of the empty bag. A backpack that's already heavy before you fill it leaves less carrying capacity for books, clothes or equipment.

Material and care

Oxford fabric, polyester and synthetic materials differ in texture, finish and care instructions. A scratch-resistant fabric can be practical for daily use, but also check the zips, seams and base. According to the product description, the Kono uses Oxford fabric and must be hand-washed. The Lenovo backpack's description mentions 70% recycled material. For the PUMA models, a minimum of 90% and 70% recycled material is mentioned, respectively.

These percentages are product specifications taken from the relevant product information; they don't automatically say anything about the lifespan or overall environmental impact of a backpack.

Frequently asked questions about backpacks

What capacity do I need for school or work?

For a school or work backpack, around 20 to 25 litres is often a good starting point. This usually provides enough space for a laptop, books, lunch and accessories. If you also need to carry gym kit or shoes, it's better to look for an expandable model or a larger travel backpack.

How long does a backpack typically last?

The lifespan depends on the load, weather conditions, material and care. Overloading your bag will cause faster wear and tear on the zips, seams and shoulder straps. Distribute the weight evenly, keep sharp objects out of the bag and follow the care instructions. A model that is hand-wash only should not be put in the washing machine.

Is a USB port on a laptop backpack safe and necessary?

A USB port is a pass-through to a power bank stored inside the bag; the power bank itself is usually not included. Check the cables and connections regularly for damage and only use a suitable power bank. The feature is handy for travelling or commuting, but not essential for a good laptop backpack.
