RE: Enabling Zoom on Mobile Devices

Ø  Also, please note that the normal ZOOM feature in all browsers is sufficient to meet this requirement.   It is therefore virtually impossible today to not meet this SC unless you either

Greg, I have to disagree, if a site designed for mobile blocks user scaling then how can I use the browser zoom feature.  The zoom feature in Safari on iOS for example does not function when user scaling is blocked so as a person with a visual impairment I am prevented from zooming in on the page with browser zoom.  Can you please explain how this does not fail WCAG – the situation described above is assuming they don’t have another in-page or apple-system-xxx font techniques as discussed earlier..

In my experience most mobile browsers do not have a zoom capability when user scaling is turned off.   Only a few offer an option to override the setting.  IMO there is an accessibility support issue on mobile for this success criteria – there is not sufficient support in browser to override the setting and therefore it’s a failure.

the width does not determine the enlargement.

with responsive design you can have a fixed width and be able to enlarge the content 300% or more.

Also, please note that the normal ZOOM feature in all browsers is sufficient to meet this requirement.   It is therefore virtually impossible today to not meet this SC unless you either

  1.  find some way to shrink your text to the same degree that someone zooms the browser  so that it doesn’t change size as you zoom’
  2.  you create content that can ONLY be viewed by a certain browser and that browser has no zoom.


The problems being cited in the other posts are assuming things that are not required by WCAG.

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?
