In this article, we will explore how to select legible fonts, maintain proper contrast ratios, and make your typography compatible with screen readers like VoiceOver.
Tools such as Google Fonts and Contrast Checker will be covered to provide practical solutions for achieving compliance with WCAG guidelines.
By the end, you’ll understand how to create readable, scalable text that not only meets ADA and Section 508 standards but also significantly improves the overall user experience on your website.
Let’s go into the key principles and tools that make accessible typography a crucial aspect of modern web design.
What is Accessible Typography?
Accessible typography is the practice of designing text that is readable and understandable for everyone, including individuals with disabilities. It focuses on clear fonts, proper contrast, scalable sizes, and adequate spacing to ensure inclusivity and usability across diverse audiences in both digital and print mediums.
Characteristics of Accessible Typography
Readability vs. Legibility
Readability refers to how easily a block of text can be read and understood. It focuses on the ability of the audience to read and comprehend text without straining. Factors influencing readability include font size, line height, and overall design consistency.
Legibility, on the other hand, focuses on the clarity of individual characters and how easily they can be distinguished from one another. This is crucial for users with visual impairments or dyslexia.
Both readability and legibility are essential in creating inclusive web designs. They directly impact the user experience by ensuring that text content is accessible to a wide audience, including those using screen readers or other assistive technologies.

Font Weight
Selecting a font with appropriate weight is critical. Fonts that are too light can be difficult to read, especially against certain backgrounds.
Conversely, fonts that are too heavy can cause visual clutter. A balanced font weight enhances legibility and makes text easier to read.
Character Spacing (Tracking and Kerning)
Proper character spacing, including tracking and kerning, can significantly affect readability.
Tight or inconsistent spacing can make text difficult to read, while well-spaced characters improve reading flow and comprehension.
Adjusting tracking for entire blocks of text and kerning for individual letter pairs ensures clarity.
X-Height and Its Role in Readability
The x-height of a font, which is the height of lowercase letters relative to uppercase letters, plays a pivotal role in readability.
Fonts with a larger x-height are generally easier to read, especially at smaller sizes. They provide better character recognition, aiding users with visual impairments or cognitive challenges.
Line Height and Spacing Considerations
Adequate line height (also known as leading) is necessary for making blocks of text readable. Space between lines should be large enough to avoid crowding but not so large that related lines of text appear disjointed.
Proper line spacing allows for a smooth reading experience and helps in maintaining the flow of content.
Color and Contrast

Color contrast ratios are essential to ensure text is distinguishable from its background.
High contrast between text and background colors increases readability for users with visual impairments. Using tools to check contrast ratios against WCAG guidelines is advisable.
Guidelines for Text-Background Combinations
Choosing the right text-background combinations goes beyond just contrast ratios. Avoid using similar hues even if they contrast well in brightness.
Effective combinations often include dark text on a light background or vice versa. These combinations prevent eye strain and enhance readability.
Addressing Color Blindness in Design
Design needs to accommodate users with color blindness. Avoid relying solely on color to convey information or distinguish text.
Use patterns, textures, or labels alongside color to ensure content accessibility. Implementing these adjustments ensures that users with color vision deficiencies have equal access to information.
Selecting Accessible Fonts
General Principles for Font Selection
Opt for widely available fonts. Common accessible fonts like Arial, Helvetica, and Verdana ensure that text is displayed consistently across various devices and platforms.
Avoid decorative or handwritten styles. While stylish, these fonts are hard to read and can be especially problematic for users with visual impairments or dyslexia.
Importance of fallback options for uncommon fonts. When using less common fonts, always provide fallback options. This ensures the text remains readable even if the primary font fails to load.
Recommended Accessible Font Types
Sans-serif fonts
- Arial, Helvetica, Verdana. These fonts offer clean lines that make text easier to read, reducing visual fatigue.
Accessible serif fonts
- Times New Roman, Rockwell. Certain serif fonts maintain readability, though they should be used judiciously.
Fonts specifically designed for accessibility
- Lexend, OpenDyslexic. These fonts are crafted with accessibility in mind. Lexend reduces visual stress, while OpenDyslexic helps users with dyslexia by using heavier bottoms to prevent flipping.
Fonts for Specific Needs
Dyslexia-friendly fonts and their benefits.
- Dyslexia-friendly fonts like OpenDyslexic aid by emphasizing the bottoms of letters, making them less likely to flip.
Fonts optimized for visually impaired users.
- Large x-height fonts improve readability by making characters more distinct.
- High contrast fonts increase visibility for those with vision impairments.
Best Practices in Applying Accessible Typography
Practical Usage Guidelines
Avoid excessive font styles.
Applying too many font styles like bold and italics makes the text look cluttered and difficult to read. Keep it simple to maintain a clean look and feel.
Use appropriate font sizes.
Under 12 points? Forget it. Aim for at least 16 points for better readability. Larger text is easier to read, especially for people with visual impairments.
Maintain consistent spacing and alignment.
Consistency is key. Uniform spacing between lines, paragraphs, and characters ensures a seamless flow. Proper alignment helps in maintaining structure.
Styling Considerations for Enhanced Readability
Left-aligned text and ragged-right margins.
Left-aligned text with uneven right margins is easier to read. It prevents the eye from straining to follow and aligns naturally. Avoiding “rivers” of white space in justified text ensures a smoother reading experience.
Avoiding “rivers” of white space in justified text
Justified text often creates awkward gaps known as “rivers” of white space. These disrupt the reading flow. Stick to left-aligned text to maintain a clean and legible layout.
Proper use of bullet points and lists.
Break down information with bullet points and lists. They make text more digestible. Well-spaced lists enhance readability and comprehension.
FAQ on Accessible Typography
Why is font choice important for accessibility?
