What is the proper way to adjust screen ( padding? margin? body width? ) so that the content is nicely width in screen resolutions such as 2560*1440?
The customizer’s desktop setting applies to screens equal or larger than 1025px.
The proper way to go is to set up everything within the Appearance > Customize > Layout > Container as content padding can also be set there but if you want to specify the styles for larger screens (4k), you’ll have to write a custom CSS for it. And you can write CSS styles specific to screen size by using @media rules.
Example:
/* styling for 1440p */
@media (min-width:2560px){
.grid-container{
max-width:1920px; /* this is the container width settings */
}
.site-content{
padding: 50px; /* this is for the padding */
}
}
