Real World Browser Size Stats Part Ii

In Part I of this article I showed you how to write your own script(s) to track the screen resolution, browser viewable size, and bit-depth, of your users. While you are gathering your own statistics, I'll offer mine up for review.

The site for which I gathered these statistics is http://algonquinstudios.com/. It is the web site for my company, Algonquin Studios. It is not a portal site, or really any other kind of traditional destination on the web. It is a site that offers corporate information. Much of the site traffic comes from searches on Yahoo! and Snap for web development, enterprise application development, and various other software and web-related topics. A good deal of traffic comes from client sites, including a popular local not-for-profit. The rest of the traffic have no referrers and most likely are existing clients, leads, or people who just check on us every now and then (competitors, partners, friends, etc.).

I started with 1,000 records, and discarded 14 that had no data. There are some records that have questionable data, but only those with a bit-depth of '0'. So that left 986 good records on which I based these results. What I've done is break the data down per resolution tier. But first I will cover the aggregate data.

The window width and height represent the viewable space within the window, not the actual window size. Instead of guessing who had what tool bars open, it seemed easier to just capture the actual usable real estate. Please keep that in mind as you view these numbers.

All Users

	Screen Width	Screen Height	Bit-Depth	Window Inner Width	Window Inner Height
Mean	941	705	21	806	485
Median	1,024	768	16	783	446
Mode	1,024	768	16	780	602
Highest	2,560	1,024	32	1,372	1,014
Lowest	640	480	0	80	51

I've also created this handy chart to show you the actual numbers and percentage breakdowns of each resolution that visited the site. The x-axis represents the screen resolution, and the y-axis represents the number (of 986) and percent of users at that resolution.

Other Users

There are also a few records that had unique settings. They are as follows:

• One user with monitor resolution of 767 x 553 x 32-bit. Viewable browser area was 763 x 442.
• One user with monitor resolution of 960 x 720 x 16-bit. Viewable browser area was 940 x 578.
• One user with monitor resolution of 2,560 x 1,024 x 16-bit. Viewable browser area was 628 x 623.

Finally

Some of you who are better number crunchers than I may be interested in looking at the log. Some of you may want to verify what I've found. You can get your own copy of the log, with IP addresses removed.

You will note some odd numbers above every now and then. Some browsers reported '0' as the bit depth. This is most likely incorrect, but I have left the data in there instead of dumping the whole record. A bit-depth of '1', however, is quite possible. You will also note that while bit-depths can come as 1, 4, 8, 16, 24, and 32, some charts show a mean bit-depth of 17, or some other number. This is an average. I leave it up to the user to determine whether or not he/she would round it up or down. In these cases, the median or mode would be more useful.
