If you're interested in setting up a mix room for Dolby Atmos, you can find all the needed information on this page:

It offers Dolby's latest DARDT-Tool (Dolby Atmos Room Design Tool), a very useful Excel-file to configure your system. You can enter your room dimensions and listening position, and then you can select speakers and subwoofers from the drop-down menus. All our models are included and we have taken great care to provide the most accurate data to Dolby. The DARDT-Tool will then show you if the selected system will fulfil the needed requirements. Make sure to allow macros, otherwise it won't work.
