Accessibility people, a question about web page zoom. Do you know how many people use text only zoom as opposed to full page zoom?

It's more complex than people realize. There are many methods by which low vision users "zoom in," including ZoomText, which operates outside of the browser. Best data I can find is from WebAIM, with an important caveat...

Surveys are based on self-reporting, which means that there are inevitably more people than the results show (fear of stigma). Our usability tests with low vision users reveal that much variability exists with "zooming." We observed everything from 0% to 1200% increase in size.

If the goal IS accessibility, it is better to ask what has to be done to make sites and applications accessible to low-vision users. That information is well established and does not have to negatively impact UX or visual design.

I was interested to know what zoom level is the standard for text zoom. WCAG 2.1 AA seems to advise 200% for text, 400% for the full page. If folks are zooming way higher than that I suspect many designs will break.
