Hi Nick, 

Welcome to the Unbounce community. 

Google forms are responsive by default so in theory, at least, they should adjust based the screen size. 

A few things you can try: 

• 
  

  Set the width & height of the form to 100% in the HTML code for the iframe

  
  


• 
  

  Make sure you check the “Show Mobile Version to Visitors” box in the Page Properties of the Unbounce editor for your mobile view. 

  
  

Here is a quick test I set up and the form seems to adjust accordingly. (although it doesn’t look that well): http://unbouncepages.com/google-form-test-new/

Can you share a link to your landing page so the community here can try to help you.

If you can’t share publicly the page, try reaching out to the awesome support team at Unbounce. 

Best,

Hristian

P.S. Any particular reason you want to use Google Forms instead of the native Unbounce forms?
