How to enlarge logo size in Dawn theme?

Topic summary

A user attempted to increase their logo size in Shopify’s Dawn theme using custom CSS, but the code didn’t work.

Solution for Dawn 8.0:

  • Navigate to Online Store > Theme > Edit code
  • Open settings_schema.json in the Config folder
  • Change the “max” value to 500 (or desired size)
  • Save changes
  • Adjust logo width to 400 in the theme customizer

This solution was confirmed working for Dawn version 9 and the Sense theme.

Mobile view issue:
Multiple users reported the fix works for desktop but causes oversized logos on mobile. One user found a solution for mobile auto-adjustment and shared a link to a separate community thread addressing this specific problem.
