What is the minimum WCAG contrast ratio for body text?

WCAG 2.2 Level AA requires a contrast ratio of at least 4.5:1 for normal body text and 3:1 for large text (18pt+ or 14pt bold). The contrast criteria are unchanged from WCAG 2.1.

What changed between WCAG 2.1 and 2.2 for contrast?

The contrast success criteria (1.4.3, 1.4.6, 1.4.11) are unchanged in 2.2. WCAG 2.2 adds criteria such as Focus Appearance and Dragging Movements — use this checker for contrast, and audit focus states separately.
