natmfat provides you with components to manage text. Pre-set configurations including font-size, weight, or leading (line height) are all calibrated to use natmfat in product. Selecting the appropriate type style is determined by layout or template structure.

Scale

The natmfat type scale is built on a single equation, based on IBM Carbon Typography. The formula for our scale was created to provide hierarchy for all types of experiences.

Style

Typography creates purposeful texture, guiding users to read and understand the hierarchy of information. The right typographic treatment and the controlled usage of type styles helps manage the display of content, keeping it useful, simple, and effective.

Weights

Font weight is an important typographic variable that can add emphasis and differentiate content hierarchy. Font weight and size pairings must be carefully balanced. A bold weight will always have more emphasis than a lighter weight font of the same size. However, a lighter weight font can rank hierarchically higher than a bold font if the lighter weight type size is significantly larger than the bold one. We suggest using IBM Plex Regular, Medium, and Semibold for digital experiences. The semibold weight is ideal for section headers, but should not be used for long text.

Italic

Each weight has an italic style, which should only be used when you need to emphasize certain words in a sentence (i.e., titles of works, technical terms, names of devices, and captions).

Type color

Type color should be carefully considered, with legibility and accessibility as paramount concerns. Keep type color neutral in running text. Use primary blue for primary actions.
