Best dimensions to fit mobile devices

[bloodylupin]

Hola,

I am developing a simple platform game with kaboom and I can't figure out what's the best way to set kaboom width and height to make the design consistent on different devices. I tried to use default options and setting the sprites dimensions to a portion of the screen width()/27 but the results are different and on mobile the screen exceeds the viewport. When I used Phaser there was an option on scale to fit the window, is there something similar? I also noticed when inspecting the canvas that when the device pixel ratio is 2, the width and the height on the html are doubled, have I to set a scale based on different device pixel ratios?

Thanks in advance 🙏
