Question 1

What minimum color contrast ratio does WCAG 2.1 Level AA require for normal body text?

Accepted Answer

4.5:1

Answer

WCAG 2.1 Level AA requires a contrast ratio of at least 4.5:1 between text and its background for normal-sized body text to ensure readability for users with low vision.

Question 2

What is the recommended maximum line length (measure) for readable body text?

Accepted Answer

45–75 characters per line

Answer

Optimal readability is achieved with 45–75 characters per line; shorter lines cause too many eye returns while longer lines make it hard to track from the end of one line to the start of the next.

Question 3

Which font characteristic can cause readability issues for users with dyslexia?

Accepted Answer

High-contrast strokes between thick and thin parts of letters

Answer

High stroke contrast (common in Didone/Modern serifs like Didot) can cause letters to blur or 'flutter' for users with dyslexia or visual processing differences.

Question 4

What does 'accessible typography' mean in the context of web design?

Accepted Answer

Typography that is legible and usable for people with a range of visual abilities and disabilities

Answer

Accessible typography ensures text is legible, well-contrasted, and properly sized so that users with low vision, dyslexia, color blindness, or other disabilities can read content effectively.

Question 5

What is the WCAG recommendation for resizable text?

Accepted Answer

Text should be resizable up to 200% without loss of content or functionality

Answer

WCAG 2.1 Success Criterion 1.4.4 requires that text can be resized up to 200% using browser zoom without loss of content or functionality.
