Length of title tag shown in SERPS is NOT 600px

[Martinus33]

Hi,
many of you may know it: The length of the title tag shown in SERPS is max. 600px, it's not dependant on number of characters. Every expert knows this and every online tool checks the 600px.

But, surprise surprise, most of my title tags, which are 500 to 580px, are truncated! All online tools give me "green", but they are actually truncated. Checking the SERPS with other keywords and title tags it confirms me that Google only shows about 520px at best.

Has G changed their 600px maximum or increased the font size? Does anybody know?

Seems that way...

Thanks.
So do I interprete JM correctly, that font size has changed? But from 600px down to 520px (using present online tools), this is a lot and probably not only due to a "subtle change of font size".
