Choosing a lightweight backpack: practical buying tips for work, travel and everyday use

A lightweight backpack may seem easy to choose at first. In practice, though, many models can disappoint. A bag may be light but offer little protection. Or it may have a generous stated capacity, while pockets and thick padding reduce the usable space.

For commuting, school, short trips and air travel, there are three key pitfalls to watch out for:

• Low weight isn’t everything: thin materials and limited support can compromise comfort and durability.
• Water-resistant doesn’t mean waterproof: a water-resistant backpack can help in light rain, but won’t necessarily keep your belongings dry in prolonged or heavy downpours.
• Measurements aren’t always taken in the same way: when choosing a cabin-size backpack, check the external dimensions, including any protruding parts and side pockets. Airlines may change their requirements.

Which specifications should you check?

1. Weight, capacity and dimensions

First, think about how you’ll use the backpack. A compact backpack of around 10 to 15 litres is often enough for a tablet, lunch, documents and a few personal items. For a weekend away, around 20 to 25 litres is more practical.

Bear in mind the difference between the weight of the bag and its carrying capacity. A very lightweight backpack may be suitable for everyday use, but less so if you’re carrying a heavy laptop, books or walking gear.

If you’re looking for a 40 x 30 x 20 cm Ryanair backpack, compare its external dimensions with the airline’s current baggage rules. According to the product information, a model of these dimensions may be intended as a personal item, but always check the terms of your ticket before you travel.

2. Laptop compartment and protection

A backpack with a laptop compartment won’t automatically protect your computer from knocks. Check:

• which screen size the compartment is designed for, such as a 15.6-inch laptop backpack;
• whether the compartment is padded;
• whether the laptop sits directly on the bottom of the bag;
• whether the compartment closes securely and isn’t too roomy.

A laptop compartment is particularly useful for commuting, studying and business travel. For a 15.6-inch laptop, the screen size isn’t the only thing to consider: the actual dimensions of laptops can vary between brands.

3. Materials, comfort and care

Polyester, canvas and similar synthetic fabrics are often used for lightweight backpacks. Check the product description for details such as tear resistance, water-repellent treatments and washing instructions. A brand’s claim about durability or protection is a product claim; don’t treat it as an independent guarantee.

For everyday use, adjustable shoulder straps, a padded back panel and a sturdy handle are useful features. A hiking backpack also needs to distribute weight well. For longer walks, a hip belt can offer more support than a basic school backpack.

Frequently asked questions about lightweight backpacks

Is a lightweight backpack suitable as hand luggage?

That depends on its dimensions and the airline’s requirements. A 40 x 30 x 20 cm model is often sold as an underseat backpack, but measure the bag including its side pockets and check the rules that apply to your ticket.

How long does a lightweight backpack last?

Its lifespan depends on the materials, stitching, zips, load and care. Avoid overfilling the compartments, keep sharp objects away from thin fabric and follow the cleaning instructions. A water-resistant coating may become less effective with use and washing.

How many litres do I need?

For everyday use, 10 to 15 litres is often enough. For work with a laptop, lunch and accessories, around 15 to 20 litres is practical. A travel backpack of around 20 to 25 litres gives you more room for a short trip, but it may also become heavier when fully packed.
