How to troubleshoot Looker Studio embed height issues in WordPress

Summary:
When embedding Looker Studio (formerly Google Data Studio) reports on WordPress pages, you may encounter an issue where the report appears cropped or shows white space—especially on mobile devices. This guide outlines how to diagnose and improve the responsiveness of embedded Looker Studio reports across screen sizes.

Issue background

A Looker Studio report was embedded in a WordPress page using an iframe. While the report displayed as expected on desktop and tablet, mobile users encountered a problem: once the iframe height exceeded 800px, it introduced white space or failed to scale properly—resulting in a poor user experience.

The goal was to show the entire report across all device types without requiring scroll bars.

Diagnosis

The issue was isolated to iframe rendering on smaller mobile screens. Here’s what was discovered:

• The report iframe was styled for responsiveness using CSS and JavaScript adjustments.
• On screens below ~500px in width, the embedded Looker Studio iframe forcibly rendered at a height of 750px due to internal styles set by Google—not by the site.
• Attempts to override this using CSS or JavaScript in the parent site had no effect because cross-origin iframes cannot be styled or resized from the outside.

Resolution steps

1. Use responsive iframe container styles
   Apply the following CSS to ensure the container is as flexible as possible:

   .iframe-container {
     position: relative;
     width: 100%;
     padding-bottom: 75%; /* Adjust as needed for aspect ratio */
     height: 0;
     overflow: hidden;
   }
   
   .iframe-container iframe {
     position: absolute;
     top: 0;
     left: 0;
     width: 100%;
     height: 100%;
     border: 0;
   }

2. Embed the iframe within that container
   Example HTML:

3. Avoid forcing height from the parent site
   Setting a fixed pixel height on the iframe often conflicts with the internal responsive behavior of Looker Studio. Let the iframe scale naturally where possible.
4. Check for Looker Studio display settings
   Within Looker Studio:
   • Ensure “Fit to width” is selected.
   • Disable any fixed height settings, if possible.
   • Review “View mode” behavior for mobile.
5. Accept limitations of cross-origin iframes
   Since the iframe content is hosted externally, styles injected from your site can’t override what’s inside. If Google enforces a minimum or maximum height at specific breakpoints, this can’t be bypassed with CSS or JavaScript on your end.

Final outcome

The Freshy team made responsive styling adjustments on the test page and confirmed that the Looker Studio report was rendering as responsively as possible—within the limits of iframe behavior. Remaining height issues on narrow screens were traced to Google’s internal styling, which cannot be manipulated externally.
