Frequently Asked Questions
What's the difference between WCAG AA and AAA line height requirements?
WCAG AA requires minimum 1.5x line height ratio (e.g., 16px font needs 24px+ line height), while AAA requires 2.0x ratio (16px font needs 32px+ line height). AA is the standard legal requirement, AAA provides enhanced accessibility for users with cognitive disabilities.
Should I use pixel values or unitless line-height in CSS?
Use unitless values (1.5, 2.0) for responsive design. Unitless line-height scales proportionally with font size changes, while pixel values create fixed spacing that may break responsive layouts. Our tool calculates ratios regardless of input format.
Does line height affect all users or just those with disabilities?
Proper line height improves readability for everyone, but it's especially critical for users with dyslexia, cognitive disabilities, and visual processing disorders. WCAG requirements ensure text is accessible to users who struggle with cramped or poorly spaced text.
What happens if my line height fails WCAG compliance?
Non-compliant line height can make your website legally inaccessible and difficult to read. Users may struggle with text comprehension, reading flow, and visual tracking. Our tool provides specific recommendations to achieve compliance while maintaining design aesthetics.
Can I use this tool for checking mobile typography?
Yes! Mobile typography often uses different font sizes, so it's crucial to verify line height ratios across device breakpoints. Check your responsive font sizes and ensure consistent WCAG compliance across desktop, tablet, and mobile viewports.
