Best .png resolution for tablet/phone/pc PnC game

Getting Started Newbie Questions
#1

I’m creating a PnC game for phone/tablet and maybe PC.

Is there a ‘best’ resolution and image dimensions for static images? The one’s that will be the ‘background’, non-moving images. Like the image of a room that fills the display and may have ‘clickable’ images scattered here and there.

Thanks!

Go for at least twice the resolution…

I usually start all my psd projects in a 2048 x 2048 px @ 326 dpi … Then I scale them down to fit my desire resolution. Images sheets are best cause you get all the @4x, @2x images and code from texturepacker software for example.
