Max length of Title Attribute

Question

What is the length limitation of HTML title attribute?

Answer 1

According W3C,

The title should ideally be less than 64 characters in length. That is, many applications will display document titles in window titles, menus, etc where there is only limited room. Whilst there is no limit on the length of a title (as it may be automatically generated from other data), information providers are warned that it may be truncated if long.
