> horizontal scrolling of vertical text is not a problem

I was thinking of several scenarios, but reading up on it there is often a mix of writing modes, e.g. apparently in Japanese:
“Where the efficient use of space is important — namely newspapers and magazines — both orientations are often combined.” [3]

So pages which use a lot of vertical writing still use some horizontal, therefore I think you are right – for each ‘bit’ of content.

To adjust the text, I’d suggest:
“Content can be resized to 400% without loss of content or functionality, and without requiring scrolling in the direction of text except for parts of the content where fixed spatial layout is necessary to use or meaning.”

Getting in to the terminology for “direction of X”, I wasn’t sure what “text line” would mean, alternative terms (reviewing the “writing modes” documentation [4]) are:

“without requiring scrolling in the direction of ______”

-          text

-          text line

-          text flow

-          writing mode

-          the text orientation

Any better suggestions? iOS/Android don’t seem to have a concept of vertical text or writing modes (from a quick google), so I’m leaning towards the W3C’s “writing mode” as it seems to be the first to define this concept.



This seems like a good starting point for learning about vertical text:
