Why is text rendered with a greater font-size in Opera?

Question

I\'m working on an HTML page that needs to be more or less pixel-perfect, and I noticed that in Opera 10, fonts are rendering larger than they do in other browsers, even tho

Answer 1

Came across similar issues, had to change my fallback order from:

font-family: Helvetica, Verdana, Arial, sans-serif;

to

font-family: Helvetica, Arial, sans-serif;

Since Arial and Helvetica are almost exactly the same size, when opera falls back it still looks good.
