There are some limits to the number of characters you can use throughout Instagram. Iâve been trying to confirm a limit on usernames but havenât been able to verify this information. However, I believe that an Instagram username cannot exceed 30 characters. Your Instagram bio cannot exceed 150 characters.
In a single tweet, you can post up to 140 characters. You may not  exceed this character count. If you upload an image with your  tweet, that will take up 22 of your charact â¦ ers, so you will be left  with only 118 characters to write your message. Twitter is a social  media platform people use to communicate with others. + 1 other found this useful.
