By Impran M N
Matching your Power BI reports to your company's branding often comes down to typography. This tutorial covers the theme JSON method for applying custom fonts, so your reports look consistent and polished across every visual.
01Open the theme JSON editor
Access Power BI's theme settings where you can edit the underlying JSON file that controls fonts, colors, and other styling.
02Edit the JSON for custom fonts
Update the relevant font properties in the JSON so they point to the typeface you want applied across the report.
03Apply the theme to your report
Load the edited theme file into Power BI Desktop so the custom fonts take effect across your visuals and text elements.
04Use it for branded business reporting
Apply this to marketing reports or executive dashboards where a consistent, branded look matters for how the report is received.
Frequently asked questions
Do I need coding experience to edit the theme JSON?
Not really — you're editing simple key-value font settings in a text file, not writing a program.
Will custom fonts display correctly for everyone who views the report?
Viewers generally need the font available on their system or via the Power BI service for it to render exactly as designed.
Can I save my custom theme for reuse in other reports?
Yes, once you have a theme JSON file set up, you can import it into any other Power BI report.
Does changing fonts affect report performance?
No, font changes are purely visual and don't impact how the report processes or loads data.
