To optimize web design, it is advisable to measure font sizes in points (pt) to maintain clarity and consistency across different devices.

Combining Serif and Sans Serif for Enhanced Readability

The combination of serif and sans serif fonts offers a strategic advantage in enhancing visual hierarchy and improving content readability within digital contexts. Utilizing a sans serif typeface, such as Public Sans, for headings alongside a serif typeface for body text creates a distinct contrast.

This clear differentiation supports consistent measures and contrast ratios, aligning with accessibility standards such as the Web Content Accessibility Guidelines (WCAG).

This dual approach is particularly advantageous for government websites, where readability is crucial for individuals with low vision or disabilities. The United States Web Design System (USWDS) emphasizes the importance of usability testing, focusing on factors such as font size, point height, and typographic combinations.

These tests ensure compliance with official directives, including the GSA Accessibility statement, thereby promoting equitable access to information and services across diverse user populations.

Line Height and Kerning Adjustments

Typographic clarity is fundamentally influenced by line height and kerning, both of which are critical for enhancing legibility in digital content. Establishing a line height of at least 1.5 times the font size helps mitigate density concerns, particularly for longer texts and primary content on government websites.

Kerning, which refers to the adjustment of spacing between individual characters, plays a crucial role in achieving a visual rhythm that is clear and consistent.

For governmental websites operating under .gov domains and those that adhere to the United States Web Design System (USWDS), it is essential to maintain proper measures and spacing. These adjustments are particularly beneficial for individuals with low vision or disabilities, as they contribute to compliance with the Web Content Accessibility Guidelines (WCAG) and align with the General Services Administration (GSA) Accessibility Statement.
