Airbus Design System uses the base Roboto, a Sans Serif font inspired by several fonts, including Helvetica. Made for the web, this font has several sizes and styles developed to balance content density and reading comfort.
Combining several parameters such as font size, font-weight, color, line height, etc, we created a set of defined text styles.
Size matters when it comes to creating content hierarchy. We created several text styles and inserted them into categories.
Heading, used as title, it helps the users quickly scan the content. Use them wisely, mix them with the spacing and your UI is going to be flawless.
Body are used for text paragraphs, several sizes are available and can be applied depending on the HMI type (18px body will better suit for public website with imagery and space)
Labels are mainly combined with other components, such as text fields, combo box, etc.
Small text is used for additional information.
