What is WCAG Font Size Requirement?

WCAG 2.2 does not require a specific px, but recommends 16px minimum for body text. Text below 12px fails for low vision users. In USA, small fonts are common reason for ADA lawsuits against e-commerce sites.

Best practice for USA: 16px-18px for body, 14px minimum for secondary text, never below 12px. Large text (18px+ or 14px bold) has lower contrast requirements.
