Minormeta-viewport-largeBest practice, not a WCAG failure
2.5%
of the 609 sites we scanned fail this
Ranging from 1.3% of Shopify DTC stores to 4.9% of Indian financial services. Pooled across five targeted cohorts, so treat it as a convenience sample rather than a rate for the web.
What it means and how to fix it
Anyone enlarging text to read it hits a ceiling before reaching a size that works for them.
The fix. Allow scaling to at least 500% in the viewport meta tag.

Share of scanned sites in each cohort. These are five targeted studies, not a random sample of the web, so read the contrast between cohorts rather than any one figure as a web-wide rate.
What this does not measureLimits of these figures, and where the corpus came from
- This rule maps to no success criterion, so a site failing it is not failing WCAG. It is still worth fixing: these are the patterns that decide whether assistive technology can navigate a page efficiently rather than merely read it.
- These are five targeted cohorts, not a random sample of the web. Per-cohort rates are the figure to quote; the pooled rate is a convenience sample.
- Denominators count sites that produced a result. Sites that were blocked or errored are excluded rather than counted as passing.
- Occurrence counts are floors: the engine records at most 25 occurrences of a rule per page.
- The EU and Indian cohorts retained only the primary success criterion per finding, so a rule mapping to several criteria contributes to one of them in those two cohorts and to all of them in the other three.
