Typography
RUB Inter is the corporate typeface of Ruhr University Bochum. We use it consistently across all digital and printed applications. The typeface family comprises over 2,000 characters and supports 147 languages. This makes it highly versatile and suitable for international use. Thanks to its clear letterforms, it supports accessible communication and is particularly easy to read.
At a Glance
We use RUB Inter in four weights: Extra Bold, Semi Bold, Medium, and Regular.
For headings, we primarily use RUB Inter Extra Bold.
For body text, we use RUB Inter Regular.

Special Features of RUB Inter
RUB Inter is highly versatile: characters that resemble one another, such as the number zero and the letter O, are clearly distinguishable, thereby facilitating accessible communication. The typeface supports accents, Cyrillic and Greek characters, as well as mathematical symbols, fractions and subscripts for scientific applications.

Substitute Typeface
If RUB Inter cannot be used for technical or system-related reasons—for example, in certain Office applications—we use Arial as a substitute. We use Arial exclusively in Bold and Regular. The use of Arial is intended only for such exceptional cases.
For languages that are not supported by either RUB Inter or Arial—such as Japanese or Sanskrit—we independently select a suitable font. This font should be as clear as possible and meet the accessibility and readability requirements of the respective writing system.
For Designers
Character Spacing in Headings
To achieve a striking effect, the character spacing can vary between 0% and −5%. For short headlines, a tighter spacing (−3% to −5%) is possible to achieve a more compact look. For longer headlines or very small font sizes, a wider spacing (0% to −1%) is recommended to ensure readability.
Typographic Hierarchy
A clear typographic hierarchy provides structure to our communication. It draws attention to key content and improves readability. The hierarchy shown here serves as a guide. Its specific application always depends on the situation.
To ensure readability, font sizes in digital formats must not be less than 14 px. For printed materials, the minimum size is 8 pt.
We choose the line spacing so that the ascenders and descenders of the letters do not overlap. This ensures that the text remains easy to read even in multi-line paragraphs and does not look cramped.

RUB Inter with appropriate letter spacing
To ensure readability, we do not use light font weights.
We always use mixed capitalization for headlines.
Do not set letter spacing too tight
Do not set the tracking distance too wide.
Do not set body text to Extra Bold—it’s hard to read
If the line spacing is too narrow, the ascenders and descenders will overlap
