For quite some time I have been wondering, whether users are browsing full screen or if they are only using a window which only takes up part of the screen.
Often I am discussing with customers of we are going to optimize towards a 1024x768 or a 800x600 resolution, but if it is common to surf in a small window, this is important to consider when designing a new website.
None of the tools I currently have access to (hitbox) are only tracking screen size, so now I have build my own tool to track it.
The idea for my tool is also to be my stat tool, but that depends on how much space all this statistics will take up. I have now started tracking throughout this site and dubidu.
I about a month I will try to evaluate on my statistics and make it public.
