Limitation of title tag is about 55 to 60 character and the Description should be 155 to 160 character.
Optimal title length. Google typically displays the first 50-60 characters of a title tag. If you keep your titles under 60 characters, our research suggests that you can expect about 90% of your titles to display properly.
Meta descriptions can be any length, but search engines generally truncate snippets longer than 160 characters. It is best to keep meta descriptions between 150 and 160 characters.
