The Perfect School Bag: Tips for Choosing Design, Ergonomics and Size
For many children, their first school bag is a real highlight – and for parents, an important decision. Beyond colourful designs and cool motifs, it's primarily about ensuring the bag is comfortable, practical and healthy for little backs. But how do you find the perfect school bag? Let's clarify the most important questions!
When should you buy a school bag?
Most parents start their search for the right school bag in spring before school starts – at this point, the school start is still six months away. Parents therefore have plenty of time to compare different models and prices. Additionally, spring offers the largest selection of school bags and many shops offer discounts.
If school start is still six months away, your prospective first-year pupil's height could still change. Therefore, choose school bags that grow with them, e.g. school rucksacks with an adjustable height carrying system.
Some parents wait for offers just before school begins. This is often cheaper and you can adapt the rucksack's fit to your child's current height. However, the selection might already be limited shortly before school starts.

School bags – what should you look for?
When choosing the right school bag, parents should consider these 6 criteria:
Ergonomics
Ergonomic school bags focus on back-friendliness. To avoid overloading the spine, the school bag should have padded shoulder straps, a reinforced back panel and ideally a chest or hip belt. With these practical straps, it's possible for your child to carry the daily weight of school books with minimal health impact.
Visibility
Reflectors on school bags are a must so your child can be clearly seen in traffic, even in poor weather or darkness.
Size
Many children experience enormous growth spurts during primary school – nevertheless, the bag should fit optimally from Year 1 to Year 6. Therefore, ensure the ergonomic school bag has a continuously adjustable back system and an adjustable chest strap. This way the rucksack can be adapted to the schoolchild's back after each growth phase.
Storage Space
Look for clever compartments and pockets so your child can stay organised. Ideally, the compartment closest to the back is larger to store heavy books there. The closer heavy items are to the back, the easier they are to carry. An externally mounted side pocket for drinks could prevent hastily closed water bottles from damaging the bag's interior should the bottle leak.
Construction
During the school years, the bag must withstand quite a lot – after all, it's in use 5 days a week. Durable and waterproof materials protect exercise books and textbooks from rain and snow. Magnetic closures offer your schoolchild easy and quick opening of the school bag – even with just one hand!
Design
Finally, your child should naturally like the school bag. Let them help choose, as they'll be carrying the bag daily. Whether with dinosaurs, princesses or cool colour gradients – design is at least as important to children as comfort. Kletties in various designs can be attached to many models as desired – so your schoolchild can alternate their favourite motifs on the bag.
How heavy should a school bag be?
The weight of the school bag is one of the most important criteria. The bag should ideally weigh no more than 10–15% of your child's body weight – including contents. If your child weighs 20kg, for example, the bag should have a maximum weight of 3kg. When buying, therefore, pay attention not only to the bag's empty weight, but also consider how heavy the school supplies might become in daily use.
A little tip: Check the bag regularly. Toys or unnecessary exercise books often sneak in, increasing the weight.
How many litres capacity should a school rucksack have?
The school bag's capacity mainly depends on the child's age and the number of required school materials:
- For primary school (ages 6 to 10), models between 15 and 20 litres are sufficient.
- In secondary school, more books, larger exercise books and additional materials are often needed, so the rucksack should have a capacity between 20 and 30 litres.
-
In sixth form, a rucksack with up to 35 litres can be useful.
