Increase Width product page

Topic summary

A user seeks help expanding the width of their Shopify product page, which currently appears constrained with significant white space on the sides.

Two CSS solutions were provided:

  1. Full-width approach: Add code to the base.css file setting .page-width to max-width: 100% with 40px padding on sides. This creates an edge-to-edge layout.

  2. Custom width approach: Modify the existing .page-width class in base.css by adjusting the max-width value (suggested: 2000px) while maintaining centered alignment with margin: 0 auto.

Both solutions involve editing the theme’s base.css file through the Shopify code editor. Screenshots demonstrate the implementation steps and expected results. The issue remains open with no confirmation from the original poster on which solution was implemented or if the problem was resolved.

Hi @ellacoker

You can try to follow this step
Step 1: Go to Edit code
Step 2: Find file base.css and add this code at the end of the file

.page-width {
   max-width: 100% !important;
   padding: 0 40px !important
}

Hi @ellacoker

You can find and change the page width of your store by adjusting max-width: 2000px; code in the base.css file

.page-width {
    max-width: 2000px; /* Adjust as needed */
    margin: 0 auto;
