Success Criterion 1.4.4 "Resize Text" is a Level AA requirement under the "perceivable" principle of WCAG 2.2. EN 301 549 clause 9.1.4.4 maps this criterion for procurement conformance.
Correct: at 200% zoom every control and block of text stays readable and usable with no loss of content or functionality. Incorrect: fixed-height containers that clip enlarged text, or zoom pinned via the viewport meta tag. maximum-scale=1 or user-scalable=no in the viewport tag is an instant failure on mobile — never pin user zoom.
Engine coverage: manual-only in the current audit tiers — no automated run can certify it.
