When designing for mobile web, its important to check designs at the physical screen size of target device. Merely looking at your PC / Mac screen at designs of the same resolution isn't enough: * Mobile devices have smaller pixels (higher pixel density), and thus X x Y pixels on a PC screen will be physically smaller on mobile devices (generally) * One 'web pixel' (i.e. a CSS pixel) will be re-sized by the mobile device. e.g. retina devices doubling up pixels.
Has anyone encountered any good tools for simulating web designs (image based, not HTML prototypes) at the correct physical size (on a PC screen) for mobile devices?
