Typography needs to offer a clear way to display text. It helps us create hierarchies, organize information, and guide our users through pages.

If the font is not displayed in a browser, the fallback font is Verdana. Verdana is the default font used on the e-mails for technical reasons.

Typography components


Heading is used to create various levels of typographic hierarchies.

See all about Headings

Body text

Body text normal is always Proximus Text Font Regular and its typically used for long-form writing

Detail text

Detail text is used for disclosing extra information or smaller items in hierarchical relationships of text. As caption and footnotes who are the smallest font sizes. They are used sparingly to annotate a table or give more small information.

Type scale uses a common library with defined text sizes and line height. Refer to Text sizes to have all the details.


While right-aligned, centered, and justified text have their place, most websites benefit from a consistent use of left-aligned text. Justified text, common in print, does not yet display well enough in a web browser to be considered a best practice.

Type set flush left provides the eye a constant starting point for each line, making text easier to read.

Line length

Controlling the length of lines of text helps readers attention flow easily from one line to the next, making reading more natural and comfortable. While a line between 40 and 90 characters can be considered as readable, we tend to suggest to have lines somewhere around 40 to 60 characters in body text and 20 to 40 characters for shorter text (such as headings).

Paragraph spacing

Information architecture is the key to a comprehensive and readable content. Relationship between text element is affected by spacing, more space will distinguish one element from the other while less space will group them together. Making sure to use spacing wisely will help your content to be more comprehensive.

Typesetting at Proximus digital

Typesetting controls the readability of a text with the size, style, and spacing of its type. It's a function of microtypography (how text is styled within a text block) and macrotypography (how content elements are arranged on the page). The more readable a text the more easily users can understand its content. Text with poor readability turns off readers and can make it challenging for them to stay focused.

Easy to read

Easy-to-read constitutes a great extra reading to write and produce content that is accessible for all.


  • No italics and condensed versions for web usage
  • No transformation and effect on the font
  • No accent on capital letters




If you need add emphasis on one and some words, you can use the Proximus bold. Font weight is an important typographic variable that can add emphasis and differentiate content hierarchy.
