Aspect ratio for Web applications

I promised a Computational Media student here at Georgia Tech that I’d post this.  He’s running an experiment to understand what ratios will work best for using HTML5 Canvas on current Internet devices.  If you’re willing to participate in his (very short) experiment, please do visit

    Hi Mark

    I suggest that the student — among other things — should look at the visual angles needed for various kinds of presentations, especially those that involve text, and also those that use decoration to help manipulation (for example, tiles in Etoys and Scratch).

    I think the results would be (are) that one not only has to use every trick in the book (including some of David Salesin’s) plus go to some kind of multilayer alpha blending scheme (we experimented with a few of these on the OLPC XO).

    Still, I think the visual angles available for many cellphone types are just not suitable for many high content web presentations, regardless of the resolutions of the devices.

    (This is why I said to Steve when he showed me the iPhone “Make it at least 5″x8″ and ….” etc.)
