I am the webmaster for Ubuntu.com and many of the other Canonical websites. I have access to browser statistics for our websites' visitors. We don't share actual numbers of visitors but I have permission to share ratios of screen resolutions of people coming to our site. This report includes many millions of visitors over the last 30 days. For brevity I've only included the top 100 screen resolutions. Those excluded from the list comprise less than 0.01% for a given screen resolution. The nice thing about the ubuntu.com website is that it attracts all kinds of users. While the forums and wiki tend to attract mostly Ubuntu/Linux users the main website gets a very good mix. http://people.ubuntu.com/~mnuzum/screenres.csv > While doing a simple mathematical scale up/down might be an interim > solution, it's not really the way to produce apps that look their best > on a smaller or larger screen.

I personally don't see a way around this. As a large screen high-dpi user I'm going to want my panels to be bigger, the spacing between buttons to be larger and the fonts to be bigger. As a small screen high-dpi user I'm going to want the text more readable, the buttons clickable but probably not waste space on padding. (just a guess though) For traditional desktop users using a unit of measurement that's based on font-size might be helpful (similar to the em's used on the web). That way if a user has a problem with an interface using a standard 9pt font they can increase it to 12pt and everything should scale appropriately. There are some problems with using EM's though, since it deals with the width of the letter M. Sometimes things grow larger than you think they should because of a surplus of thin letters. Someone more familiar with typography would have to chime in to suggest a better unit of measurement. By the way, I have to keep re-editing my text to be more clear... the term "high resolution" is very ambiguous. It could mean "a lot of pixels" or "a high dpi." I think that a lot of problems revolve around the growing availability of high dpi screens, regardless of resolution. I could be wrong though. To add another little bit of discussion material, there are probably two users who have high dpi screens. There is the technical user who wants more screen space. They want to see more. Then there are a lot of users who are simply sold a higher DPI screen because "bigger is better" and a "high res" screen *must* be better than a dorky low-res screen, right? (what, your screen isn't HD?) Check out Dell's website and you'll see what I mean... it's clearly being sold as a suggested upgrade. The user who wants more screen space will complain if we take away their extra pixels by using larger buttons and fonts. The user who just wants "higher res," whatever that means, currently gets a hard-to-use desktop experience that takes a lot of fiddling to overcome. We've done a lot of talk, is there any action that can be taken? -- Matthew Nuzum newz2000 on freenode _______________________________________________ Usability mailing list Usability@gnome.org http://mail.gnome.org/mailman/listinfo/usability
