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...

User testing or website usability

I'm not even sure if usability is actually a word beyond the realms of websites and graphical user interfaces. Anyhow, user testing is a research component of the website usability consultancy service offered by Callisti.

A client's website is examined in several ways: what does the unassuming user discover unprompted when visiting the website; how does the user navigate through the site and what is her experience of this; how does the client intend the website to work; etc.

By compiling the findings we can report back on a convergence strategy that aims to improve ROI and goal conversion from the client's point of view while simultaneously improving user feedback.
