Picture size to look the same Mobile abd desktop

[SouthernCustom]

I've read through as many old posts as I can and still don't see an answer that works -what is the best size for a product picture to be so it looks the same on mobile and desktop? I've tried every sequence and still is either huge and cut off on mobile preview or is so small it's blurry

Hi SouthernCustom,

See your other post.   Suggest trying 720 x 720 as noted in the other response.  It's worked for me however, there's no guarantees but, at least worth a test.
