Chris Tuner wrote blog posts on Meta title and older posts from a year or so ago from SEOmofo.
He said that it’s not about the number characters of Meta Title but width in pixels of those characters together.
Now, question is how long can it go? Figures are about 584 pixels wide, which can be over 107 characters.
Now I understand that why Google shies away from giving a specific number of characters on the title tag. It’s not about number characters but what is best way to find the accurate characters, Simple search out.
