How to buy a backpack: choose a model that suits school, work and travel

Buying a backpack might seem straightforward – until you’re commuting daily with a laptop, books, gym kit or travel essentials. A bag that looks roomy in the online shop can turn out to be awkwardly organised in practice. And a backpack with a laptop compartment doesn’t automatically offer enough protection or carrying comfort.

When comparing, pay particular attention to these common pitfalls:

• A laptop compartment that doesn’t fit your device: a 15.6-inch laptop won’t fit in every compartment labelled as a “laptop sleeve”. Always check the maximum screen size and the internal dimensions when available.
• Lots of pockets, but little usable space: small zip pockets are handy for accessories, but they also take up room. So look at the capacity in litres and the main dimensions.
• Comfort claims without concrete details: adjustable shoulder straps are useful, but for daily use you also need a padded back panel, good weight distribution and possibly a chest strap.
• Material claims without context: “durable” can refer to abrasion resistance, recycled material, or simply a marketing position. Check what the product specifications actually say.

Which specifications matter?

1. Laptop size and organisation

If you’re looking for a laptop backpack or backpack for a laptop, first check compatibility. A backpack for 15.6 inches is designed for laptops with a maximum screen size of around 39.6 cm, but the chassis can vary between models.

A padded laptop compartment is a practical feature. It helps keep the laptop separate from books and accessories, but it’s no guarantee against damage. Place the device carefully and avoid hard or sharp objects pressing against the compartment.

A backpack with a laptop compartment is especially handy for students, professionals and commuters who travel between home, school and the office every day.

2. Capacity, dimensions and carrying style

For a school backpack or compact work backpack, a capacity of around 20 to 25 litres can be enough for a laptop, documents, lunch and a few accessories. If you also need to carry clothes or larger items, it’s better to look at a roomy backpack.

Compare the dimensions as well as the litres. A bag that is 48 cm high can feel noticeably bigger than a 43 cm model, especially on public transport. A handle is practical when you want to lift the bag briefly or set it down beside you.

An expandable model offers extra flexibility. Just check that the bag remains comfortable when fully loaded and that the zips and shoulder straps are suitable for the extra weight.

3. Material and carrying comfort

Nylon and polyester are commonly used for everyday backpacks. According to the product information, the Kensington SP25 uses 1680 denier nylon. That’s a concrete material specification you can factor into your comparison. Other models may simply list synthetic material or polyester.

Also look out for:

• padded shoulder straps;
• a padded back panel;
• adjustable straps;
• a chest strap for longer walks;
• mesh side pockets for a water bottle;
• sturdy zips and sufficiently wide seams.

For a sporty backpack, ventilation, freedom of movement and a lightweight design are often more important than a formal look. A women’s backpack or men’s backpack doesn’t necessarily have a different technical design; fit, dimensions and style are usually more decisive than the label.

A black backpack is easy to pair with workwear and gym kit. With dark materials, do check the care instructions, as dust and wear can become more visible.

Frequently asked questions about buying a backpack

Which backpack is suitable for a 15.6-inch laptop?

Choose a model that explicitly states a maximum screen size of 15.6 inches or 39.6 cm. For a large laptop, also check the chassis dimensions. A padded laptop compartment offers extra separation, but don’t pack the laptop together with sharp or heavy items.

How big should a backpack for school or work be?

For a laptop, documents, lunch and daily accessories, around 20 to 25 litres is often practical. If you also need to carry gym kit or clothes for a short trip, choose a roomy backpack or a model with expandable capacity. Bear in mind that a larger bag isn’t automatically more comfortable when you load it heavily.

How do you maintain a backpack so it lasts longer?

Always follow the manufacturer’s care instructions. Remove dirt with a soft, slightly damp cloth and don’t use harsh cleaning products unless expressly permitted. Don’t overload zips unnecessarily, distribute the weight across the compartments and store the bag dry. This will help limit wear to the material, seams and fastenings.
