Typography and fonts
Visual identity
Typography is an important part of TxDOT’s visual identity. Below is information for the official TxDOT brand fonts.
General best practices
- Use upper and lower case for headlines.
- Use different weights and sizes to create content hierarchy.
- Generally, font size and weight decreases moving down or through a page/document.
- Body content should be between 16 to 20 pixels or 8 to 12 points.
- Line length should be 45 to 90 characters.
- If using color for headlines, use TxDOT blue.
- Never use TxDOT red for written content.
Approved brand fonts
Only use the approved brand fonts listed below. The primary typeface/font for communications is IBM Plex Sans. It has two versions, regular and condensed, which provide a range of weights.
IBM Plex Regular
IBM Plex Condensed
Font alternative
When IBM Plex Sans is unavailable, use Verdana. Verdana is native to Windows and MacOS.
Important: All TxDOT brand templates are built using Verdana and do not require installation of IBM Plex Sans.
Getting brand fonts
IBM Plex Sans and IBM Plex Sans Condensed are available for free from Google fonts.
Accessibility best practices
- Color contrast between text and background colors should be 4.5:1.
- Content must be 8 points in size or larger.
- Body content line spacing must be 1.5 times the font size.
- Content must not rely on color alone to communicate information.
- Use clear and direct language and avoid jargon.
- Consistently use typographic styles for headings and body content.
