I am finding a conflict between articles I find through google, some suggest 163 ppi for iphone spirtes and others 72 ppi.
163 ppi seems to be the more correct answer to me. However all the Corona tutorials use 72 ppi.
Does anyone know the proper ppi? Anyone tested this on a real device?
EDIT: I know it depends on the device, lets just reference everything in regards to the iphone < iphone4 [import]uid: 9484 topic_id: 18563 reply_id: 318563[/import]

How you size your objects by resolution is up to you.

So basically what you are saying is that 163 ppi would be the optimal for all previous iphone versions. So Corona tutorials are a little bit misleading using 72 ppi, which doesnt take full advantage of any device. So if I use 163 for my standard images and use that same image at twice the size for iphone4 it will then get compacted into 326 ppi on the device?

The answer really depends on how large your image needs to be and the clarity of the resolution. Most game pieces don’t need pixel perfect images, and 72 pp is usually more than enough for a rocking good game. It’s pretty much a standard for mobile and some console games.
Bottom line… use the lowest resolution you need to get the job done to save load times, CPU cycles, and texture memory.
It’s necessary to match the display resolution of the target device, just that imagesare proportioned and scaled correctly.
