No. Do not mess with Instagram bio font.
I will be transparent. Custom Instagram bio fonts do a great job making an Instagram profile stand out. Not in a good way.
Instagram knows a thing or two about a good and clean design. It is at the core of Instagram philosophy.
There is a reason why they use Neue Helvetica as a default Instagram font. Including bio.
Neue Helvetica is a clean and readable font. It works great on every possible device. Stick to it and maintain a professional and clean bio.
