How do you determine the coordinates of a game's play screen area?

In Intro to JS, Dave talks about using the screen's coordinates 0,0 to 600 on the y axis and 800 on the x axis to determine where you place the game's coins... however, what's confusing me is what determines the size of the game's play screen? Is this measured in pixels or something else? And most importantly, how do you determine exact locations of objects in your game other than through a bunch of guesswork? There has to be a better/easier way. Thanks for your help!

yes from phaser they are stored when you instantiate the 

    game = new Phaser.Game(800, 600, Phaser.AUTO, '', { preload: preload, create: create, update: update, render: render

They are in pixels.

I believe to retrieve the values it is game.height or something like game.height and game.width
