A 15.6-inch laptop backpack needs to do more than just hold your laptop. Students often carry books and a charger too, while commuters require space for lunch, documents and accessories. If you travel, you’ll also want a sturdy layout, compact dimensions and handy features.
Yet many shoppers fall into the same traps. A backpack can look spacious in product photos, but in reality have few usable compartments. Terms like water-resistant and lightweight are also not always clearly explained. With the following checklist, you can compare models on the features that really make a difference for daily use.
The label “15.6 inch” refers to the maximum screen size, not the exact external dimensions of your laptop. A business laptop with a wide bezel, sturdy casing or an extra-large hinge can therefore feel tight. Always check:
A laptop backpack with a dedicated laptop compartment protects mainly through a combination of material, padding and a good fit. No backpack is automatically resistant to drops or impacts.
A waterproof laptop backpack and a water-repellent model are not the same thing. “Water repellent” or “water resistant” usually means the material helps to ward off light rain or splashes. That is useful for a short bike ride, but it is no guarantee that the contents will stay dry in prolonged rain or if submerged.
Pay attention to the product description, seams, zips and closure. A roll-top or flap design can offer extra sealing, but check whether the product actually states a waterproof rating. If that information is missing, assume protection against limited moisture and, in bad weather, consider using a separate rain cover.
A roomy laptop backpack is handy, but a full bag quickly becomes heavy. So don’t just look at the number of litres. Also check:
A lightweight laptop backpack can be pleasant for commuting, but a slightly larger model is more practical when you also need to carry clothes, books or accessories.
For a laptop up to 15.6 inches, a compartment with clear padding is an important starting point. Do not place heavy items loose next to the computer. A charger, power bank or metal water bottle can put pressure on the casing when you move. Use small accessory pockets to keep the contents separate.
Nylon and polyester are common materials for a business laptop backpack. The fabric thickness, lining, stitching and zips all help determine how suitable a model is for intensive use. The Kensington SP25, for example, specifies 1680 denier nylon, along with reinforced internal compartments and multiple accessory pockets. These are verifiable product specifications; they do not guarantee a particular lifespan.
A 25-litre backpack offers a different user experience from a slim model designed for just a laptop and documents. According to the product information, the HP Travel 25-litre laptop backpack has a capacity of 25 litres, expandable to 30 litres. This is especially relevant for travellers who sometimes need to pack extra clothes or personal items.
Alongside capacity, also check the external dimensions. One bag may fit in an overhead locker, bike crate or locker, while another model is too deep. Some models clearly state their dimensions and weight, such as the Kensington SP25: 480 × 330 × 180 mm and 710 grams.
The choices below are linked to different usage scenarios. Always check the current product page and confirm that your laptop fits in the compartment in terms of dimensions.

No. The screen size is only one indication. The casing can vary by brand and model. Therefore, measure the width, height and depth of your laptop and compare these dimensions with the laptop compartment. Allow extra room if you use a protective case.
That depends on the material, load, frequency of use and maintenance. A backpack that is heavily loaded every day will wear out faster at the shoulder straps, base and zips. Distribute the weight, avoid overloading and store the bag in a dry place. The statutory warranty for a product still applies; the Kensington SP25 and HP Travel both state a minimum of two years’ statutory warranty.
A laptop backpack with a USB port can be practical when you want to connect your phone to a power bank inside the bag while on the go. The USB connection itself does not usually contain a battery. So check whether the cable is suitable for your power bank and do not use the connection as a substitute for laptop security or water protection.
