What is the standard screen size anyway?

What are you designing for?

There is a glut of possible display resolutions or screen sizes for your viewing interface now, largely due to variation and convergence of traditional computer display screens, digitalisation and wide screen, then HD television.

These are roughly split between 3 main contenders:

18% approx - 4:3 ratio (following in the great VGA tradition)
42% approx - 16:10 (Widescreen)
20% approx - 5:4 (1280x1024 pixels)

It is a design consideration for fixed width display websites but also for desktop wallpapers based on bitmap images. There are some new Allan McNish images available on the official website...
