Ratio is a Dashboard widget for calculating common screen resolutions of various sizes. Includes presets for HD, NTSC, PAL, Apple iFrame, iPhone/iTouch, iPhone 4, iPad, Microsoft Zune HD, Windows Mobile, and Surface, Fullscreen and Widescreen PC, and more.

Handy for working with various image sizes, element scaling, and other common CG calculations (tailored for motion graphics and interactive design, this widget does not calculate DPI or non-square pixels).

The double arrows let you swap width and height settings, easily switching an iPhone or Zune HD from vertical to horizontal, or more easily dealing more...
