Choosing the right size
The following size guide will help you choose the right suitcase size based on the length of your trip and your personal packing needs. This will help you quickly determine whether a compact carry-on suitcase is sufficient for a short trip or whether you’d be better off opting for a medium or large model for longer journeys.
What are the maximum permitted dimensions?
The 158 cm rule sets the maximum permitted size for checked-in luggage on flights. This does not refer to a single edge length, but to the so-called ‘girdle measurement’. This is calculated as the sum of the suitcase’s width, height and depth. In practical terms, this means: you measure your suitcase along its three external dimensions (including wheels and handles) and add these values together. The result must not usually exceed 158 cm for the suitcase to still be accepted as standard checked-in luggage. If this measurement is exceeded, the luggage may be classified as bulky luggage depending on the airline and incur additional charges.
| Suitcase size | Duration of trip | Suitcase height | Volume | Hand luggage |
|---|---|---|---|---|
| Suitcase size S | Up to 3 days | 50–55 cm | 35–50 L | Yes |
| Suitcase size M | Up to 7 days | 60–69 cm | 50–80 L | No |
| Suitcase size L | 1–2 weeks | 70–79 cm | 80–100 L | No |
| Suitcase size XL | 2–3 weeks | from 80 cm | 100–140 L | No |
Crossover bags
A crossover bag is the perfect companion for anyone who can't decide between a rucksack and a handbag. Crossover bags are a hybrid of the two. The shape resembles a rucksack, but is more triangular. Crossover bags are worn on the back, but not over both shoulders like a classic rucksack, but diagonally, like a shoulder bag. However, the shoulder strap is usually a little wider than that of a rucksack or shoulder bag, which gives the crossover bag a sporty look.
Crossover bags for sport and everyday life
Crossover bags are suitable for many different leisure activities. They are particularly popular with sports enthusiasts. Thanks to their low weight, they are ideal for carrying all the items you need when jogging, cycling or inline skating without having to carry too much weight. Crossover bags, which also have a hip belt to prevent them from slipping, are particularly suitable for all sporting activities. The shape with the one-sided shoulder strap also ensures that you can easily access the main compartment at any time by simply swinging the bag forward. But crossover bags are also perfect for everyday use. At koffer24 you will find different models for every situation.
