In Hungary, both motivating factors are present: larger companies follow the "business" practices of their parent companies, while smaller ones opt for a different size to conform to the image created by EU forms.

Our company typically produces three sizes in mass. In our file submission section, we demonstrate the correct layout for the standard 90x50 mm size. The 90x50 mm business card, which can also be considered the domestic standard, enjoys an absolute majority. This is the conventional and widely recognized shape, so most business card orders don't even consider deviating from the trend.

The second most important size is the so-called EU-sized business card, measuring 85x55 mm. In everyday language, it's even called the "bank card" size, and orders for this size come primarily from medium-sized companies.

The third size – which might be considered increasingly popular – measures 90x55 mm. Although orders for this size are almost negligible compared to the total annual production, it still ranks third in production statistics.

There is also a general interest in rounded-corner business cards, which lend a modern and elegant appearance. These are most popular with the 85x55 mm cards, as they evoke the design of bank cards—a look that is familiar and instills confidence in most people.

We have seen sizes of 50x50 or 60x60 mm as well, but these are more form-breaking rather than fitting into the typical business card category. The need to express uniqueness is most apparent in these sizes – sometimes in a rather clever way.

Breaking forms with forms

The reasons for alternative and innovative sizes can be found not only in the typography and colors but also in the design, taking into account their combined advertising-psychological effect. It is also true that with the explosive development of computing technology, the number of users has grown exponentially, and consequently, more creative minds have been able to engage in the process of visual design and style creation. Meanwhile, software developed for graphic purposes has become increasingly "smart," almost offering visual elements even in the realm of business card creation.
The combination of these two factors results in graphic solutions that, in the realm of printed communications, until recently could only be observed on an artistic level.

All of this directly implies that the visual elements require space and harmony, which must be reflected in the size of the business card being designed. The size not only frames the creative work but also constitutes a crucial and essential element in starting the project.
Additionally, the practical usability of business cards must be taken into account. Cards that are too large may not fit well in wallets or card holders, while those that are too small might get lost or fail to convey a sense of professionalism. This is why it is important to align creative ideas with practical considerations.
