What are the layout guidelines for 2K/4K resolutions?

Question

Layout

Let's say the design was developed with a frame width of 1920px, all the elements are located as they should and everything is very harmonious. But what happens if someone opens the site on a higher resolution monitor? Do professional web developers think about such cases? What to do in such situations? Increase the size of the font and elements everywhere by 2-3 times?

Answer 1

1. Used relative units for fonts.
2. Use percentages for measured values.
3. Use svg for images where possible. Where impossible - srcset
4. Use grid and flex. They can be customized however you like.
5. The main thing: to accurately represent for whom the site is being made and what device the user has.
