Viewport for embedded Unity in a web browser?

we are going to embed a Unity file into a webpage. However, we were asking ourself if there is some standard height in pixels for the unity animation, which can ensure that user doesn't have to scroll vertically. The target would be a common PC with Chrome, let's say. 1366x768 should be, then, the minimum requirement. So, considered the address bar and what is on the top of a browser like Chrome (normally), which is, in your experience the height of the viewport to be considered in this case as a good choice?

Thanks! Fabio
