First of all, there is no official ADA-compliant font or font list.
The ADA (Americans with Disabilities Act) does not approve or require specific fonts. WCAG (Web Content Accessibility Guidelines), the technical standard most courts and regulators use to measure ADA compliance for websites, does not name required fonts either.
More importantly, font choice is not a compliance requirement. The font you use on your website will not make you non-compliant, and it will not create legal exposure. It is, however, a readability and UX decision that directly affects how easily your users can read your content.
This guide covers the most legible, accessible fonts for websites in 2026. It also explains what accessibility standards actually say about typography and how to make sure your font choices are working for your readers.
What makes a font accessible?
These are the five properties that make a font accessible:
- Ascenders above capital height: lowercase letters with ascenders should sit visibly higher than their capital counterparts (h/H, d/D, l/L).
- Open counters: the internal spaces in letters like o, c, e, and a must be open, not closed or tight.
- Distinct characters: similar characters (Il1 / 0O) must be clearly different from each other.
- No mirrored letterforms: d/b and q/p must have unique shapes, not be reflections of each other.
- Varied character widths: characters should have distinct widths, not uniform ones that make them harder to tell apart.
Note: These properties determine how legible a font is at its core. But the font itself is only one part of accessible typography. Size, spacing, contrast, and implementation all play an equally important role, and are covered later in this guide.
How we picked these fonts
We started with a broader list of widely used web fonts, including Roboto, Inter, Open Sans, Arial, Segoe UI, Calibri, Trebuchet MS, Source Sans 3, and others, and put each one through the same test.
Each font was tested against the five accessibility properties covered earlier in this article. To do this consistently, we used a fixed test string:
cocoa Il1| rn m 0O bdpq minimum hH lL bB fF
Each part of that string targets a specific property. Every font was tested at the same size and weight, and assessed visually, including zoomed-in checks on characters that were borderline.
We scored one point per property passed, out of a maximum of 5. Fonts scoring 4 or 5 made the final list. Fonts scoring 3 are included only where they bring something specific to the table, such as government compliance or research-backed reading support, and their gaps are called out clearly.
The best accessible fonts for 2026
- Atkinson Hyperlegible Next
- Inclusive Sans
- Verdana
- Public Sans
- Lexend
#1. Atkinson Hyperlegible Next
Atkinson Hyperlegible is a text font created by the Braille Institute for people with low vision. Every character is designed to be as distinct as possible, developed with input from low vision communities and tested for legibility. The Next version, released in 2025, expands on the original with seven weights, variable font support, and coverage for over 150 languages.
The one gap is mirrored letterforms. The letters b and d remain mirror images of each other. For readers with dyslexia, who are more likely to reverse or rotate letters, this is a real: b/d confusion is one of the most common letter reversals. Worth noting: p and q are handled well and do not share the same problem.
#2. Inclusive Sans
Inclusive Sans is a text font designed by Olivia King for accessibility and readability. It takes the friendly personality of contemporary sans-serifs and pairs it with specific design choices: clearer character distinctions, non-mirroring letterforms, and wider spacing baked in to make it highly legible across all uses.
The one area it falls short on is ascenders above capital height. Lowercase letters like h, l, and b sit at the same height as their capital counterparts, which reduces how distinct word shapes look. The impact is small for most readers, but more noticeable for low vision and dyslexic readers who rely on whole-word recognition to read.
#3. Verdana
Verdana is a text font designed by Matthew Carter, commissioned by Microsoft in 1996, specifically for screen legibility. Screens at the time were low resolution, and most print fonts became blurry at small sizes. Verdana solved this with wide letter spacing and generous proportions.
Two limitations here. Capital I and lowercase l are both plain vertical strokes with no crossbars or distinguishing features. This has a broad impact, affecting anyone reading character-sensitive strings like passwords, serial numbers, or place names such as “Illinois.” The second is shared with most fonts: b and d remain mirror images. This is a lower-stakes gap for general readers but a genuine issue for readers with dyslexia.
#4. Public Sans
Public Sans is a free, open-source font developed by the US Web Design System (USWDS), adapted from Libre Franklin. It was built for US government digital services, with a focus on neutrality, legibility, and trust. Because USWDS recommends it as the default typeface, it is used across hundreds of US federal websites, making it a practical choice for teams building ADA-compliant digital services.
Two gaps worth knowing. Zero and capital O are visually very similar, with only a subtle width difference between them. This is a practical problem for any reader dealing with character-sensitive content, and a bigger concern on government platforms where accuracy matters. The second gap is mirrored letterforms: b and d remain mirror images, which is a lower-impact issue for most readers but problematic for those with dyslexia.
#5. Lexend
Lexend is a variable font created by Dr. Bonnie Shaver-Troup and type designer Thomas Jockin, developed in partnership with Google. It is built around the idea that adjusting letter spacing and font weight reduces the visual effort it takes to process text, particularly for readers who struggle with fluency.
It shares the same two shortcomings as most fonts in this list. Zero and capital O are slightly similar but distinguishable with close attention. The mirrored b and d are a minor concern for general readers but a notable one for readers with dyslexia, for whom letter reversal is a known challenge.
The font is only part of the picture
Choosing the right font is a strong start, but it will not carry the full weight of accessible typography on its own. Size, spacing, line length, and contrast all play an equally important role. A well-chosen font set in the wrong size or with insufficient contrast will still be hard to read.
#1. Font size
WCAG does not set a universal minimum pixel size. However, 16px (1rem) is a widely recommended starting point for body text.
Make sure you use relative units such as rem, em, or percentages instead of fixed pixels so users and browsers can scale text without breaking layouts. This matters because WCAG SC 1.4.4 requires that text can be resized up to 200% without loss of content or functionality.
If a user has changed their browser’s default font size for accessibility reasons, a pixel-based declaration overrides that preference entirely, breaking that requirement.
Example:
html {
font-size: 100%;
}
body {
font-size: 1rem; /* 16px at default settings */
}For headings, maintain a clear size hierarchy so they are distinguishable from body text by size, not just weight or colour.
h1 { font-size: 2rem; }
h2 { font-size: 1.5rem; }
h3 { font-size: 1.25rem; }
body { font-size: 1rem; }#2. Line height and length
Tight line spacing forces the eye to work harder to track from one line to the next.
WCAG SC 1.4.12 requires that users can set line height to at least 1.5 times the font size without loss of content or functionality. Setting 1.5 as your default works well for most readers. Use a unitless value rather than pixels, so line height scales proportionally if the font size changes.
Also, lines that are too long make it hard to find the start of the next line. Lines that are too short create a choppy, effortful reading experience. The recommended range is 45 to 75 characters per line. The ch unit in CSS lets you control line length by character count.
body {
line-height: 1.5;
}
main {
max-width: 70ch;
}#3. Text spacing
Spacing between letters, words, and lines directly affects how easily the eye can distinguish and move between characters. Too tight, and letters blur together. Too loose, and the connection between words breaks down.
WCAG SC 1.4.12 requires that users can apply the following without losing content or functionality:
- Letter spacing to 0.12 times the font size
- Word spacing to 0.16 times the font size
- Spacing after paragraphs to 2 times the font size
You do not need to set all of these by default, but your layout must not break if a user applies them. A common failure is fixed-height containers that clip text when spacing increases.
A solid default that satisfies the requirement and improves readability out of the box:
body {
line-height: 1.5;
letter-spacing: 0.012em;
word-spacing: 0.016em;
}
p {
margin-bottom: 2em;
}#4. Text contrast
You can choose the most accessible font, nail the font size, line height, and spacing, but if color contrast fails, your text will not be readable.
WCAG SC 1.4.3 requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold). This applies regardless of font choice.
Some reliable combinations:
| Text | Background | Notes |
|---|---|---|
| #212121 | #FFFFFF | Softer than pure black, still very high contrast |
| #000000 | #FFFFFF | Maximum contrast |
| #000000 | #FFFDE7 | Cream background, easier on the eyes for long reading |
| #FFFFFF | #1B1B1B | Dark mode equivalent of the first option |

FAQs on accessible fonts
ADA does not maintain an official list of approved fonts. What it requires is that the text is readable and accessible, which means sufficient contrast, scalable text, and adequate spacing. Any font that supports those requirements can be ADA-compliant. The fonts in this article are good starting points.
There is no fixed pixel size mandated by ADA. The guidance is that text must be readable and resizable. In practice, this means using relative units like rem instead of fixed pixel sizes, so text scales when a user adjusts their browser settings. A 16px base size is a widely accepted starting point for body text.
No single font is universally perfect. Based on our testing, Atkinson Hyperlegible Next and Inclusive Sans score the highest against the five accessibility properties. The right choice also depends on your audience and context.
Verdana was designed specifically for screens and performs well on several properties: open counters, varied widths, and ascenders. Its main weakness is that capital I and lowercase l are both plain vertical strokes, making them easy to confuse. It scores 3 out of 5 and works well as a fallback font.
Atkinson Hyperlegible Next is specifically designed for low vision users and is the strongest choice. Inclusive Sans is also well-suited, with features that support both visually impaired and neurodiverse readers.
Lexend is built around reducing visual stress during reading, making it a strong choice for users who struggle with reading fluency. It scores 3 out of 5 on the accessibility properties in this article: zero and capital O are slightly similar, and like most fonts, b and d remain mirror images. For long-form reading and education platforms, it is a solid option.
Roboto is clean and well-optimised for screens, but our testing found several issues. Capital I and lowercase l are difficult to tell apart, and zero and capital O look very similar. On mirrored letterforms, both b/d and p/q remain mirror images of each other. It scores 3 out of 5 on the five accessibility properties. It is a reasonable choice for general use, but not the strongest option for accessibility-focused projects.
Montserrat is a geometric font with very uniform letterforms, which makes it visually striking but harder to read at length. Characters like I, l, and 1 are difficult to distinguish. It scores poorly on the five accessibility properties and is better suited to headings than body text.
Georgia is a serif font designed for screen legibility. Our testing found that zero and capital O are easy to mix up, and both b/d and p/q remain mirror images of each other. For most readers, the impact is moderate, but for those with dyslexia, the mirrored letterforms are a genuine concern. It is better suited to headings than body text in accessibility-focused contexts.
