Site Zoom Depends on Primary Domain

[Glow_Up_Fits]

When the primary domain on my site is chicboutiquefashions.myshopify.com, the site displays properly. When I change the primary domain to maisondemodes.com, which is the store name, the entire site zooms in. I have to zoom out my browser to 80% to make it look right. Why would my primary domain change my site zoom? How can I fix this? Thanks.

The zoom is happening now regardless of the primary domain. I added zoom: 80% to my body tag and all is well. Still don't understand what made it increase.
