Option 2: Advanced Way To Change The Default Font Size Via The Code Editor

If you want greater control over font sizes, you can make changes in the code editor. By making changes to the settings schema, you can customize font sizes beyond the default options provided in the theme editor.

2 Important Notes:

  • Before making any code changes, it’s important to duplicate your theme and work on the copy. This prevents accidental modifications that can break your live website. To duplicate the theme, simply click on the ellipsis (…) to the left of the Customize button, and then select Duplicate.  
  • The location and name of the file differs from theme developer to theme developer. The code may be located under theme.scss.liquid, and the name could be “base_size
  1. Log in to your Shopify admin and navigate to Online Store > Themes
  2. Click (…) to the left of the theme you want to edit and select Edit code.
  3. Locate the Config folder and click on settings_schema.json.
  4. Search for “heading_scale“, this controls the heading font size range. And/or “body_scale”, this controls the body font size range. 
  5. Change the default values to your desired minimum “min” and maximum “max” font size (NOTE: use % not px for the size).
  6. Don’t forget to save!

Head to the Theme customizer > Typography. You should now see the font size range you entered, allowing for finer control over your website’s typography. You may have to refresh the screen.
