What screen resolutions should I use if I would like to...

I have searched, most threads are from 2012, Some say "960 x 640?" Which seems small since a few phones are 1440 x 2560 pixels.

Thank you

If I would so want to make a mobile game with Scirra, what screen size should I use?

Looking at landscape.

As example, Mobile game in landscape mode.

Map needs to be bigger than just a screen size, but how do I know what the user will see on the phone? (Will they see everything in the marked area? " - - - - - - - -"

The awesome part with Construct 2 is that it autoscales to the device size. I use 650,350 resolution and my phone is double that resolution size yet the game scales perfectly. I use the inner scale instead of letterbox scale. I have an android device what do you have?

There are two sizes:

• Window size: the size the player can see at once; marked with dashes (- - - -) in layout view,
• Layout size: the size of the layout; can be larger than window size; it can be, let's say, the size of the map you want. Then, use different techniques (for example, add Scroll To behaviour to your player to follow it).

About the best resolution, I'm not sure either.
