How can I adjust the width of my product page?

Topic summary

A user’s product page appears excessively wide on desktop and wants to reduce its width to match a reference image they provided.

Two solutions were offered:

  1. Custom CSS approach: Add specific CSS code to the theme.liquid file (placed above the </body> tag) to control page width through custom styling.

  2. Theme settings method: Navigate to Online Store > Themes > Customize > Theme Settings > Layout, then adjust the “Page width” setting directly in the theme customization panel.

The second responder suggested checking if the theme has built-in width controls first, and offered to examine the store directly if that option isn’t available. Both solutions aim to constrain the maximum width of the product page for better desktop display.
