⚠️ As of February 25, 2026, Atlas no longer generates or imports themes. If you already have the Atlas theme installed, your theme is unaffected and everything in this article still applies. New users can use Atlas to generate home pages and product pages and import them into any Shopify theme. For the full breakdown, see What's new with Atlas: page builder update.
Go to Online Store > Themes in your Shopify admin
Click Customize on the Atlas Theme
In the left sidebar, scroll down and click Theme Settings
Select the Typography section
From here, you can change:
Heading fonts (used for titles, banners, product names)
Body fonts (used for descriptions, buttons, and paragraph text)
Font sizes and weights depending on your section layout
Tip: Choose one heading font and one body font to keep your store clean and consistent. Avoid using too many font styles at once.
Click Save when you’re done to apply your changes across the site.
