What are the specs for a top bar in a web application (1440px) according to Material Design?

I'm new to UX design. As a fun project, I'm designing a calendar web application while referring to Material Design. I can't seem to find anything about the top bar specs for web apps on the Material Design Website. What is the height of this top bar (for a 1440px screen)? Is it the same as top bar navigation on a mobile app? Looking at Google Photos seems to be around 88px...

Help would be much much appreciated.
