WebKit enforces a minimum font size of 9px when no explicit font size is
specified. This means that the font for rt cannot fall below 9px if it is
relative to the user agent default. It may be that we want to consider
modifying this minimum for ruby text and allow it to go below 9px though.

Of course. The website I was using has the line height set too tight for

it looked better. OTOH, that site loads a style sheet that overrides the ruby

In printing the standard is 50% of the base text. For larger point sizes like
headings, the size of ruby is often smaller than 50%.

So, how about we default to 50% and see how they come out. Glyphs designed for

That document also states:
When the size of base characters is very small (for e.g. smaller than seven
points), ruby which is half the size, will be even more small and illegible. In
such cases where the size of base characters is very small, ruby is not a
suitable method of annotation. In
I think 5px is way too small. Maybe 7 or 8 at least but even those are
really hard to read in high-resolution displays. See
Yeah, that demo makes me think maybe 9px is fine after all. :)

Thank you Ryosuke. This is a good demo. 5px is only barely legible and I agree
it is too small. 6px is legible but not fun to read. 7px looks reasonable lower
bound to me.
12pt text with 96dpi would translates to 16px, 50% ruby would be 8px. 10.5pt
which is often used by printed books is 14px,
Does this work?
Right. It is partly because webkit currently does not use glyphs that are
designed for ruby. I would not worry this too much as with 14px many kanjis are
only barely legible in anyway without the context. The lower bound for ruby can
be 8px for base 16px = 12pt in 96dpi. I am reluctant to raise
