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

A backpack may seem simple to choose, but marketing copy can make comparisons difficult. For example, “large capacity” says little if books, lunch and a laptop do not fit sensibly. “Water-repellent” also does not automatically mean that your bag is completely waterproof.

When choosing, pay particular attention to these three common pitfalls:

  • Incorrect laptop size: a 15.6-inch laptop will not fit every compartment labelled with a similar size. Always check the internal dimensions and the thickness of your device.
  • Confusing water-repellent with waterproof: a coating can help keep light rain at bay, but prolonged exposure to heavy rain may still allow moisture through.
  • Too much capacity without carrying comfort: a large backpack is not automatically comfortable for everyday use. Padded shoulder straps, a supportive back panel and a well-organised layout make a real difference.

Which features should you check?

1. Laptop compartment and internal dimensions

When looking for a 15.6-inch laptop backpack, do not just look at the number in the product name. Manufacturers do not always measure screen sizes and compartments in the same way. So make sure you check:

  • the maximum laptop size stated in the product specification;
  • your laptop’s dimensions, including its protective case;
  • whether the laptop compartment is padded and securely closed;
  • whether your device can be accessed through a separate zip.

A separate laptop compartment prevents your computer from sliding around among books, chargers or a water bottle. If a backpack only has one large main compartment, extra protection in the form of a sleeve is advisable.

2. Material and protection from rain

A water-repellent backpack is useful for cycling and commuting, but read the warnings carefully. According to the product information for the NINETYGO College-Style backpack, the bag is made from 900D tear-resistant fabric and has a level 4 water-repellent finish. The same information states that the bag is not completely waterproof and should not be exposed to heavy rain for prolonged periods.

Also check the base. A removable or easy-to-clean bottom is practical when you place the bag on a wet floor. Pay attention to the zips and seams too: water-repellent fabric does not automatically protect every opening.

3. Weight, capacity and organisation

A lightweight backpack is suitable if you mainly carry a tablet, bottle, wallet and a few small items. For school or work, you will often need more space. Look at:

  • capacity in litres;
  • number of separate compartments;
  • dimensions of the main compartment;
  • maximum load stated by the manufacturer;
  • adjustability of the shoulder straps.

For example, a 12-litre backpack is compact for everyday use, while a model of around 22 to 24 litres offers more room for books, clothing or sports kit. Do not fill a bag beyond the recommended capacity. An overfilled backpack puts extra strain on the zips, seams and fabric.

Choosing a backpack for different situations

A school backpack usually needs room for books, a pencil case, lunch and possibly a laptop. Students and working professionals are more likely to need an organised work backpack, with space for a laptop, charger and documents. For train journeys or short trips, a luggage strap, easy-access compartments and comfortable carrying options are useful.

A unisex backpack in a neutral colour works well with a range of clothing styles. If you are looking for a sporty appearance, consider reflective details, mesh side pockets and a model that can also be taken to the gym. For children, choosing the right size is more important than having the largest possible main compartment.

Frequently asked questions about backpacks

Which backpack is suitable for a 15.6-inch laptop?

Choose a model with a separate laptop compartment whose maximum internal dimensions are clearly stated. Measure your laptop with its case and compare those measurements with the product specification. Do not rely solely on “15.6 inches” in the title; the stated dimensions may vary between models.

How long does a backpack last?

Its lifespan depends on the weight carried, how it is used and how well it is maintained. Tear-resistant fabric and reinforced seams can help with everyday use, but overloading will shorten its lifespan. Clean your backpack according to the manufacturer’s instructions and allow it to air-dry. Do not leave wet items in a closed bag for prolonged periods.

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

For short journeys and light rain, a water-repellent backpack can be practical. In prolonged or heavy rain, a rain cover or waterproof protection is a wiser choice. Also check whether the zips, seams and laptop compartment offer additional protection.
