If you were to make your own digital drawing, how would you know how to create the sizes?

Hi,

How do you create the different sizes on another image for the app icon? Thanks

Lana

Hi Lana,

I would first create a high-res icon and then scale it down.

For example, the iPhone App images, which are 60pt@2x and @3x: I could create an image with 180x180px (that's 60px@3x -> 60*3 = 180) and then scale it down to 120x120px.
