# How do I change the font size on mobile and desktop separately?

At present, the theme provides font size controls for desktop only. The mobile font size is automatically optimized through our built-in responsive code and cannot be adjusted independently via the Theme Editor.

If you need different font sizes for mobile and desktop:

* You can add custom CSS overrides to control font sizes per device. Please note that custom code is not preserved when using the one-click update feature and must be reapplied after updates.
* If you don’t have technical knowledge, you can [contact our support team](https://nextsky.co/pages/purity), and we’ll assist you with the customization.
