RE: Enabling Zoom on Mobile Devices

I consider limiting user scaling a violation under 1.4.4.   The SC is clear that use of AT is not permitted to meet the requirement.

Subject: Enabling Zoom on Mobile Devices

Hi All--

Is it required under WCAG 2.0 AA that users can enlarge mobile sites to 200%? The question came up during our monthly accessibility forum, and I haven't been able to find anything about it online.

Apparently it is not uncommon for designers to set a fixed width for Responsive Web Designs, which, it seems to me, would be a violation of 1.4.4.

Your thoughts?

Mike
