I want to grab screenshots of some web pages, as seen by common users. I know that I can use wkhtmltopdf to do this, and pass custom values for the user agent and screen size, as per the example here: https://code.google.com/p/wkhtmltopdf/issues/detail?id=596
However, I'm not so sure where I can get a list of the most common screen sizes for my country (China).
I've seen the list here (http://www.bigbossmas.com/web-development/list-of-mobile-device-sizes/) but it doesn't show the frequency, so I'm not sure which ones to pick to get my 'top 10'.
Does anyone have a list, or a pointer to a tool which will generate the screenshots for popular combos?
