Storing this for yours and my convenience, here is a list of web-safe areas. The web-safe area is the maximum real estate available in a web browser, before a scrollbar is added.
These values apply only to maximized browsers, and should work for most of the browsers out there (in their standard UI configuration), although most certainly not all. There are no guarantees, but these are probably as close to “industry standard” as we’ll ever get.
Note: These sizes should work even with a vertical scrollbar.
