RE: Horizontal Scrolling for Reading Text: Why it doesn't work.

Wayne,

Interesting research and if I have read it correctly. As the WCAG 2.0 only recommends 200% and based upon your research. There is no difference between wrap and zoom. Should the SC be updated or change to include wrap magnification to permit a higher level?

Wayne,

I'm deeply grateful for your research on this!  I always knew it was a pain, but I did not truly understand how bad it was until I experienced it myself.  I want the world to understand this now!

If you would want to understand why horizontal scrolling is really not the following gives a quantitative explanation. Nobody has ever done this analysis before.

You cannot make an informed judgement of Resize Content and Linearize without considering this proof of extreme user need. Two dimensional scrolling of blocks of text is not just annoying it is a profound disruption of the reading process.
