@thinksinc Hey! Moved this over to the Wishlist category so we can note it for the team.
I have seen past discussion about this. If you are familiar with CSS you may be able to follow the tips mentioned in this thread: Set max width for an entire page/section (Wix Studio). Otherwise, please don’t hesitate to submit your idea to become an official feature request! Head on over to the Product Roadmap and click the ‘Request a Feature’ button.
If you didn’t previously have experience with our first fully responsive platform, Editor X, then going from Wix Editor to Studio will be a little bit of a learning curve. We do offer many resources to help with this stage, and the Studio Academy is a great place to start: Wix Studio Academy
Keep in mind, you can still enjoy all the benefits of the Studio workspace but continue to edit your sites with the Classic Editor (you do not have to use the Studio editor if you prefer not to).
