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.)

context.drawText(x,y,string); context.getFontAscent();
context.getFontDescent();
context.getFontLeading();

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