How to Change Font in Map Viewer

[EdwardCronin]

Hello ESRI community. 

I have been asked to change the font of an experience builder application and web map from the default text to Arial. Is this possible to perform on ArcGIS Online? I have not found a way to change font for the legends, reference text, or table text in AGOL.

Any advice on strategies to accomplish this would be appreciated. Thank you for your time and assistance!

You can change the font for an experience in the theme settings. There are 9 fonts available including Arial.:

Some widgets can also choose a font, so ensure it's also set correctly on layout items like Text.

Additional fonts would require experience builder developer edition.
