RE: Low Vision Needs

> Do you think we need a WCAG Low Vision failure to specifically address resizing viewports?

My thought would be we would have one that covers up to 200% as part of current WCAG with the user agent note that most desktop browsers ignore the viewport maximum and thus a user agent that ignored it would allow it to pass as well similar to how SC 1.4.4 works with desktop browser zoom in general.

And then we would create a more broad low vision failure that addresses viewport scale beyond 200% or perhaps less than 100%.  For many people with low vision 200% won't be sufficient and for other people for example with RP may want to reduce the size of the text below 100%.

Hi Jon,

Do you think we need a WCAG Low Vision failure to specifically address resizing viewports?

Adopting the text from 1.4.2 in UAAG 2.0 and maybe 1.4.1 and 1.4.3 too might help.

Best Regards,
