At the heart of document accessibility lies a fundamental element that often goes unnoticed – the choice of typefaces and fonts. While fonts may seem like a design afterthought, they play a pivotal role in determining how content is consumed and understood. This comprehensive guide will explore the crucial role of typefaces and fonts in document accessibility, their profound impact, and strategies to craft truly inclusive content.
Understanding Document Accessibility
Document accessibility refers to creating content that can be easily consumed and understood by individuals with disabilities, ensuring that no one is left behind. Legal requirements, such as the Americans with Disabilities Act (ADA) and the Web Content Accessibility Guidelines (WCAG), mandate accessibility for digital content. Failure to comply with these accessibility standards can have legal repercussions, underlining the importance of making digital content accessible to all.

The Importance Of Typefaces And Fonts
Typefaces, commonly known as fonts, are the building blocks of typography. They encompass various styles and designs of characters, each with its unique characteristics. Understanding the distinction between typefaces and fonts is the first step in making informed font choices.
To navigate the world of typography, you need to grasp key terminologies such as serif, sans-serif, font size, line spacing, and more. These terms will serve as a compass as we explore the intricacies of font choice and accessibility.

Special Contemplations For Accessibility
Typeface Readability
Use Simple Fonts: Fonts that are straightforward and familiar are easier to read because our minds can quickly recognize their shapes and patterns. Unfamiliar or complex fonts require more time and effort to interpret, affecting readability negatively.
Avoid Character Complexity: The human mind processes simpler shapes and patterns in typographical text more efficiently. Complex fonts, especially used in long text sections, can introduce cognitive load and slow reading.
Avoid Character Ambiguity: When characters within a font resemble each other closely, it creates ambiguity that the brain must resolve, slowing down reading speed and comprehension. Ensuring distinct characters within a font is crucial for readability.
Use A Limited Number Of Variations: Every time a new typeface, font, or font variation is introduced, readers must build a mental map or model of the characters and patterns. This consumes cognitive effort and time. Using familiar typefaces reduces this overhead.
Consider Spacing And Weight: Adequate spacing between letters and words enhances readability by clearly separating characters and words. Additionally, the thickness of glyphs (font weight) can impact readability.
Ensure Sufficient Contrast: Text is easiest to read when there’s a clear contrast between the text and its background. Proper contrast improves readability significantly. However, excessive contrast can introduce visual disturbances and hinder readability.
Avoid Small Font Sizes And Anti-patterns: Font size plays a significant role in readability. While there is no specific minimum font size requirement in the accessibility standards of WCAG, it is still a vital consideration. Smaller text can be challenging to read, especially for users with visual impairments. Relative font sizes offer more flexibility for users to customize text presentation than absolute units such as pixels or points.
Real Text Vs. Text Within Graphics: Real text, rendered as text characters within a web page, provides numerous advantages over text within images. It is highly adaptable, allowing users to customize it for better readability, change font faces, adjust text colors, and translate it into different languages. Real text can also be copied and pasted, adapted to various screen sizes, and made more compatible with search engines. It also performs well in low-bandwidth environments.
On the contrary, text within images loses most of these advantages. When enlarged, it can become pixelated and difficult to read, posing challenges for users with visual disabilities. Therefore, accessibility guidelines recommend using real text whenever possible.
The Importance Of Embedded Fonts
Modern browsers support font embedding, a CSS technique that allows web pages to download fonts and display text in those font faces. While most system-level typefaces are designed with readability in mind, many custom-designed fonts may not prioritize accessibility.
It is essential to choose typefaces and fonts that maintain high levels of readability when using font embedding. Changing the font face does not impact screen readers or other types of accessibility as long as the underlying text remains in an accessible format

Best Practices For Designers And Content Creators
Guiding Principles
Educate Yourself: Stay informed about accessibility standards and best practices to make informed design decisions.
Choose Accessible Fonts: Select fonts that prioritize readability and inclusivity, favoring sans-serif fonts for body text and using appropriate font sizes and contrast ratios.
Test With Real Users: Conduct usability testing with individuals with disabilities to gather feedback and make necessary improvements.
Use Proper Markup: Employ semantic HTML to structure your content correctly, making it easier for screen readers to interpret.
Provide Alt-Text: Include descriptive alt-text for images and other non-text content to ensure that screen reader users receive context and information.
Offer Alternative Formats: Consider providing content in multiple formats, such as PDFs and HTML, to accommodate different user needs.
Stay Updated: Keep your content and technology up-to-date with the latest accessibility features and standards.
Use Accessibility Tools: Streamline document accessibility and remediation through accessibility tools such as PREP to access features like auto-tag detection, support for multiple file formats, compliance with accessibility standards, affordability, scalability, quality, and quick turnaround times.
