Best practice height/character count for text in tategaki format


On a web page, what is the maximum good practice height (in pixels) for text
written in tategaki format?

A height of about 500px looks good to me, which is about 40 characters.

Are there heights either are too long, or too short, which make reading
uncomfortable/difficult?




I think 40 characters per line is a good upper limit. This is how novels are
typically typeset on paper. See this [image search results for 小説 +

Lines longer than this start to be unfamiliar and difficult to read. If you
care for smartphone screens, 30 characters per line should be safer.
