Is iMac Retina 5K suitable for webdesign?

It is time to retire my old MacBook Pro which served me well for over 5 years, since I dont require portability I am leaning towards buying an iMac 27 with 5K display. I work as a web designer and my question is:

  • How will a Retina display affect a website design workflow?

I found this interesting article but I am interested in your personal experience and opinions.


Retina displays are definitely suitable for web design. There are some things you should understand when using them though.

  • Typically, Apple’s “Retina” branding is applied when a display is 220 pixels per inch (PPI) or higher.
  • 220PPI+ displays are common, especially on mobile devices.
  • One CSS pixel (px) is equal to two display pixels on Retina Macs. CSS pixels are an abstracted unit of measurement. They relate to the pixels on the display, but they are not always mapped 1:1.
  • One macOS point = one CSS pixel (except when zoomed etc).
  • The 5K iMac’s screen uses the Display P3 colour space. This might actually be the biggest hurdle when using a new iMac. You’ll have to be careful on how your design tools of choice are set up, and there will be some situations where colours appear oversaturated — currently that happens in Chrome, Sketch and software that doesn’t handle colour management well (I expect these issues to be fixed eventually).
