How to Underline Text in Instagram (Caption, Bio, Story)

Instagram captions and bios do not support true underline. The workaround is using Unicode underline formatting.

Quick Answer

Instagram does not provide a real underline option for captions or bio. You can underline text using a text formatter that applies Unicode underline characters, then paste it into Instagram.


Underline Captions and Bio with a Formatter

  • Type your text into a formatter.
  • Select Underline.
  • Copy the underlined text.
  • Paste into your caption or bio.

Underline Text in Instagram Stories

Stories are different. Instagram has native text styling options there, but underline availability depends on your font and updates. If you do not see underline, use the formatter method and paste into the Story text box.


Best Practices

  • Underline only a few words, not full paragraphs.
  • Underline can reduce readability on small screens.
  • Test on dark mode and light mode.
