Need some understanding of Builder Width

Need help Responsiveness
1

Usually the system most of us use are 1080p … means they are 1920 pixels wide and 1080 pixels in height. Let’s not consider the height as the websites are scrollable, but why is Bubble’s max builder width 1400 by default ? And when doing responsive websites, why do we not consider 1920 as the default ?

I know I can edit them, but is there a standard that everyone is using ?

1400 is large - people like me with wide monitors,
1200 is default - normal 1920x1080 dimensions
960 is apple mode - basically a 3x mobile width
640 is tablet mode - 2x mobile width
320 is mobile mode. - 1x mobile width

Hope that helps you understand a little bit.

Usually I start with 320 then work up.
