Why won't my banner images fit in the Dawn theme?

Topic summary

Main issue: In the Shopify Dawn theme’s Image banner, uploaded images are auto-zoomed/cropped and won’t display fully. Reducing image dimensions doesn’t change the visible framing; it only becomes pixelated. Using “adjust to image size” makes the banner excessively large and still doesn’t fit the whole image.

What’s been tried: Multiple images of different sizes/aspect ratios were tested. Previously suggested forum solutions were reviewed but did not resolve the behavior. The user seeks guidance on modifying the banner container (“banner box”) to control how images fit.

Assets: Two example images were attached and are central to understanding the display issue.

Status: Unresolved. The user is requesting concrete steps to edit the banner section so images can fit without unwanted zooming/cropping or pixelation, and to understand how Dawn handles image sizing in the banner.

I’m new to the Shopify platform and I am just trying to fit images within the image banner in the DAWN theme and everything seems to get zoomed in, no matter how I size the image. If I make the image smaller, it just keeps it the same size within the banner box but makes it super pixelated. If I set it to “adjust to image size” it is way too big. Even then it doesn’t fit the entire picture within the banner box.

Hoping I can get some guidance on this! I’m just trying to understand how the banner box can be edited. I’ve read quite a few other posts on here and the solutions haven’t worked at all for me.

These are 2 of the images I’m trying to fit. No matter what other image I put in though they all seem to not fit.
