Graphic safe areas for Web pages

 
[Safe Assumed Web Values]
 

    In the years since the above information was put together, browser manufactures have added more tool-bars to the top of Web browsers. More important, many third party sites and programs now also want to add a tool-bar to the top of the user's Web browser. So 240 pixels of screen height may be a more reasonable "expected minimum" for viewable page area.

    Personally, I would not presume more than 200 pixels of viewable screen height. Which also provides some hope, that by using the right browser program (like Opera) in "full screen" mode, a site will still be easily usable on the top end pocket PC's, that some business executives strongly favor. As those provide only a 640x200 LCD display.

    The North American (NTSC) WebTV will only display a maximum picture or table width of about 540 pixels. That system having a claimed (maximum) safe area of 544 wide by 376 high. And for any Webpage wider than that, it will start to shrink image sizes, etc., to force the page fit on the screen width. (It will not scroll horizontally.)

 
[More Safe Assumed Values]
 

    Most printers can now print larger images (in dots or pixels), than the original printers could output, using (only) the portrait page orientation. However, the above (535 x 670 pixel) size is still the best assumed maximum dimensions for any item within a Webpage.
