Yes, but this is not my question.
Why do you think do i want to know the exact length? Because I'm a prof of mathematics, fallen in love with naked numbers?
No, it should help me to use the place as good as possible and to avoid the ugly cut with dots. So it should help me showing a good description which people like to click.
I guess the number of characters depend on how good you fill the first row in terms of pixels. If there are some small words at the end of the first row, like "it is a top...", then you will fill it good and get more characters in total.
Can anyone confirm?
