Relating to maximum resolution, Washington said, “You can run Metro style apps on a screen as big as 30 inches with a resolution of 2560 x 1600.” Though it’s unclear if this means Metro will not run on a higher resolution, it’s more likely that this is an example of a large resolution that Metro supports. Similarly, to use the Snap feature, which allows multiple apps to share the screen, a minimum resolution of 1366 x 768 is required, which allows a 1024 pixel-wide app, as well as a 320 pixel-wide sidebar. Washington pointed out that this would support 98.8 percent of Windows 7 installations, and that the minimum would make apps richer as well as prevent developers from having to test apps at resolutions below that. One of the most important considerations was in defining a minimum resolution of 1024 x 768 pixels required for the display of Metro apps.


Microsoft put a large amount of thought into screen resolution, which varies as much as screen size does. Windows 8 will support 98.8 percent of Windows 7 installations. Windows 8, especially on the Metro interface, is designed to look and function well in all three scenarios. Microsoft is focusing on screens for three primary uses: “Slates” that tend to be 10.1 to 17 inches, “Workhorse PCs” typically from 12 to 15.6 inches, and “Family Hubs” that are either large monitors or, more commonly, high definition televisions 23 inches and larger.

The screen sizes available in devices varies immensely, from 1 inch in small handheld devices to well over 600 inches in a stadium display. Windows 8 supports many screen sizes.Washington talked the least about screen size–the diagonal, corner-to-corner measurement of the display area of the screen.
