This will be a short article, last week I was struggling to add a new line in Instagram Bio, so I did some research and the solution was very simple, no app or third-party websites needed.
As shown in the image, tap on the 123 button on iOS and the RETURN button will appear on the right-hand side of the keyboard. Tap that button and voila, a new line break appears.
Hope this helps people who are trying to write a killer bio for their Instagram page and need help with a line break. Share with your friends and family if you found this article helpful.
