html5 page size

Hello everyone.

I've created html5 web offline application with resolution 740x460, but it doesn't fit into iphone screen emulator. Even when i'm in "Retina display" mode.

If i'm chosing "Retina display" mode, page is stretched and html5 works incorrect.

Here is design code of the html5 app.

Canvas is the same size as body.

Simulator and iphone device display only 60% of the page in one screen. Application is launching on Safari.

How to fit page in to screen without scrolling anywhere?
