Can't you determine the size from the accessible version you are
doubtless creating inside the <canvas> element? ;-)
(This assumes that if you draw a string in 8px Monaco on a <canvas>, and
do the same thing in a <span>, the span will have the same size as the
canvas version. But that seems to make sense to me.)

Hang on; can we even get these for existing text styled with CSS in web
pages?
