The Red Hat Display typeface is intended for larger-scale uses, such as headings on your website and headlines in print. Red Hat Text is designed for better legibility at a smaller scale, which makes it more effective for longer body copy. (We will also be providing an additional font for body copy in print at a later date.)
Both are variable fonts with several preset styles (e.g., light, bold, black) as well as customization capabilities (e.g., weight, slant, width, etc.), providing great flexibility across print and digital uses and high usability for those with little or advanced design experience.
