At first glance, a backpack seems like a straightforward purchase. In practice, though, it often takes a few weeks or months to discover whether a model really suits your needs. A bag may look spacious, but can become awkward once you need to fit in a laptop, lunchbox and sports kit. Terms like "water-repellent" and "ergonomic" don't tell you much without further details.
This practical buying guide helps you compare a backpack on the features that really matter. Whether you're looking for a school backpack, work backpack, sports backpack or travel backpack, pay close attention to dimensions, carrying comfort, organisation and materials.
A 15.6-inch laptop backpack isn't automatically suitable for every laptop of that size. Manufacturers may quote the outer dimensions of the bag, while the laptop compartment is actually smaller. Always check whether the product description explicitly states a compatible screen size. Also consider the position of the compartment: a padded compartment against your back generally offers more protection than a loose internal pocket without padding.
A water-repellent backpack can help ward off light rain or splashes, but that doesn't mean the contents will stay dry during a prolonged downpour. Look at the wording used and check whether there's any mention of a coating, covered zips or a rain cover. For important electronics, a separate cover remains a practical addition.
A spacious backpack isn't necessarily comfortable. A large main compartment without any organisation can mean books, cables and clothes all get jumbled together. Conversely, a compact backpack may be unsuitable if you carry lots of things every day. So, alongside capacity, pay attention to multiple compartments, an adjustable carrying system and the shape of the back panel.
For a 15.6-inch laptop backpack, you need to distinguish between the laptop size, the laptop compartment size and the overall outer dimensions of the backpack. A compartment for a 15.6-inch device will fit most standard laptops, but for a thicker model, also check the available depth.
A backpack with a laptop compartment is handy for commuting, studying and working from home. For school or everyday use, a model without a separate laptop compartment may be sufficient, for example if you mainly carry books, clothes and accessories.
Think ahead about your daily luggage:
A capacity of 18 to 24 litres often suits daily use. If you carry extra clothes, shoes or travel essentials, you may be better off with a roomy backpack that has an expansion option.
A lightweight backpack reduces the weight of the bag itself, but carrying comfort also depends on the shoulder straps and back panel. Look for adjustable, preferably padded straps. A padded back panel can make contact with the contents more comfortable.
Also check the material. Polyester and synthetic fabrics are widely used for everyday use. A product description may mention durable construction, but treat this as a product feature rather than a guarantee of a specific lifespan. Zips, seams and the attachment points of the shoulder straps are areas that take extra strain with regular use.
Why this fits the profile: This sporty backpack combines a clear layout with a 22-litre capacity, making it suitable for school, daily use and light sports activities.
The 22-litre main space, front zip pocket and mesh side pocket make the organisation more specific than a bag with just one large compartment.
22-litre capacity, two-way zip, padded back panel and adjustable shoulder straps. According to the product information, at least 90% of the material consists of recycled materials.
Why this fits the profile: The two main compartments and multiple pockets suit users who want to keep school supplies, accessories and daily essentials separate.
The available compartment layout prevents everything ending up in one large main section. The stated dimensions of 45 x 30 x 18 cm help you compare the bag against your own items in advance.
Approximately 24-litre capacity, padded straps and back, two mesh side pockets and an internal pocket with elastic trim. The product information mentions support for devices up to 18.7 inches.
Why this fits the profile: This model is designed for commuting and travel. The expandable construction offers flexibility when you need to carry more on certain days.

Not automatically. The screen size is only one factor. Also check the width, height and thickness of your laptop and compare these with the dimensions of the laptop compartment. If in doubt, a small margin is practical so the zip doesn't come under strain.
The lifespan depends on the material, carrying weight, frequency of use and maintenance. A bag that's heavily loaded every day puts more strain on seams, zips and shoulder straps. Distribute the weight, don't overload the pockets and follow the manufacturer's care instructions.
First remove all items and dirt. Then clean the bag according to the washing or care label. Don't use harsh products if the material or coating could be damaged by them. Allow a wet backpack to air dry completely before storing it away.
