b++ Typetester has the base font size option
By popular demand Typetester now has an option to set preview pane’s base font-size.
Remember, em units act like multipliers for a given base size. In short, the base size of 12px and the font size of 1.2em will result in 14.4px which is rather nasty number. Just keep it in mind when applying to your layout…

Ahh, but if you set the base font size to something like 67.5% (I don’t remember the exact number), then you can use em sizing to acheive pixel perfect results, at least that’s what I’ve been told. I think I got that from the book Professional CSS, but I searched and searched and couldn’t find anything.
67.5% base font. 1em = 10px, 1.2em = 12px, .9em = 9px, etc…

Default font-size in most browsers is 16px, therefore 62.5% is nailing it down to 10px (16 × 0.62 = 10).
There’s however, many designers who still don’t get it, but IMHO the future is bright.

Ahh, I thought I had it wrong :)
How did you learn that, was there an article somewhere?
