Thanks for reaching out.
I do appreciate that you have included an image and the URL to the store as that is super helpful. As I am looking at the store, I did not notice what could be causing the width of the store to display as wide as it is currently. Would you let us know which theme you are using? If you are unsure about which theme is live on your online store, you can navigate to the Theme Editor and select the three dots to see who the theme is designed and supported by. I took a screenshot from my test store to show you the section I am referring to:
The sizing of the online store may be due to the coding of the theme. Once we determine which theme you are using we can then look towards the next troubleshooting steps.
Looking forward to your response.
Thanks for the quick reply.
I went ahead and added the Impulse theme to my test store to see if my online store would have a similar issue. It looks like the width of the Impulse theme is displaying fairly normal on my side. Did you make any custom coding changes to your theme? As this could be the reason the online store is appearing as wide as it is.
Since the Impulse theme is designed and support by Archetype Themes it would be best to reach out to their support. They can take a closer look into the coding of the theme to see what may be causing the width of the store. You can reach out to the third-party developers using their Contact Us page.
Let me know if you have any questions.
