Choosing a backpack for school, work or travel: how to avoid a bad purchase

A backpack may seem simple to choose, until your laptop does not fit, the shoulder straps dig in or your belongings get soaked in the first shower. For school pupils, students, commuters and travellers, choosing the right model is about more than colour or brand. Dimensions, organisation, carrying comfort and material determine whether a backpack remains comfortable in everyday use.

Marketing terms can be confusing. For example, a bag may be advertised as “spacious” without stating its capacity in litres. “Water-repellent” also does not automatically mean that a backpack is fully waterproof. Use the checks below to compare models based on practical, verifiable features.

Three common backpack pitfalls

1. Laptop size does not tell you everything

A 15.6-inch laptop backpack is not automatically suitable for every laptop of that size. The device’s external dimensions, thickness and the shape of the laptop compartment may vary. So do not just check the maximum screen size; also check the available space and the backpack’s dimensions.

2. “Water-repellent” is sometimes interpreted too generously

A water-repellent backpack can help keep out light rain, but zips and seams remain potential weak points. Look for information about the material, coating and fastening. If a product does not state a specific water-resistance rating, do not treat the bag as a waterproof protective case.

3. Lots of compartments do not automatically mean a practical layout

A spacious backpack with several compartments can help you stay organised, but only if the compartments suit what you carry. A laptop backpack for work, for example, benefits from a separate laptop compartment, space for documents and an easily accessible front pocket. For travel, a larger capacity, room for clothing and secure fastenings are more important.

Which specifications should you check?

Size and capacity

For a backpack for school or work, capacity in litres is a useful point of comparison. A compact model of around 13 litres is suitable for everyday essentials, while a travel backpack of 25 litres or more provides space for clothing, accessories and electronics.

Also pay attention to the external dimensions. According to the product specifications, the HP Travel 25L 15.6-Inch Blue Laptop Backpack has a capacity of 25 litres, expandable to 30 litres. Its stated dimensions are 32 cm wide, 24.5 cm deep and 44 cm high. This is relevant information when using public transport, placing it under a seat or taking it as hand luggage; always check your carrier’s rules.

Laptop compartment and protection

A backpack with a laptop compartment should keep your laptop separate from books, clothing and other hard objects. Check:

• the maximum screen size, for example 15.6 inches or 39.6 cm;
• whether the compartment is lined or padded;
• whether the laptop compartment can be accessed separately from the main compartment;
• whether the laptop stays securely in place when the bag is upright.

The HP backpack states that it has a dedicated compartment for laptops up to 15.6 inches. According to the product information, the Michael Kors Jaycee has an internal tech compartment for a laptop or tablet. However, the product description does not specify the exact laptop dimensions the compartment can accommodate. Measure your device beforehand.

Carrying comfort and weight distribution

For a backpack for work or everyday commuting, padded, adjustable shoulder straps are important. A chest strap can help make a larger bag more stable to carry. Pack heavy items close to the back panel and distribute smaller belongings among the compartments.

Also consider the empty weight. According to the specifications, the HP Travel backpack weighs approximately 860 grams. This leaves more capacity for your own belongings than a heavier model with a similar capacity.

Frequently asked questions about backpacks

How big should a backpack be for a 15.6-inch laptop?

Do not look only at the screen size. Measure the laptop including its bezel and check the internal dimensions of the laptop compartment. A model stating “15.6 inches” may vary in depth and width depending on the version.

How long does a backpack last on average?

Its lifespan depends on the load, frequency of use, moisture, and the quality of the zips and seams. Do not overfill the bag, place sharp objects in a separate compartment and follow the care instructions. Some products are covered by a statutory guarantee of at least two years in the European Union; this is separate from normal wear and tear.

Can I use a water-repellent backpack in heavy rain?

Not without additional protection. “Water-repellent” generally indicates protection against limited moisture exposure, but it is not a guarantee of waterproofing. In prolonged or heavy rain, use a rain cover and, preferably, carry electronics in an additional protective case.
