What are the optimal dimensions of the application workspace for mobile devices?

Question

iPhone

Making a game in HTML5 format for mobile devices. What is the optimal workspace size?

Answer 1

Scale graphics depending on the resolution (three sets of pictures) and use elastic design.
The first set is for screens up to 480x320 or so, the second is for 800x480, 1024x768, 1280x800 devices, and the third is for iPad 3.

Answer 2

“Mobile devices” are now considered everything from simple phones to tablets with resolutions from 128x128 () to halfHD, or even FullHD resolutions.
So you can either avoid segmentation or concentrate on specific platforms.

Answer 3

Optimal - try to look for statistics on browsers and screen resolutions used in them.
