Windows platforms use four different sizes of icons, as follows:
Size | Values |
Shell Large | User selected. Standard sizes are 32x32 and 48x48. |
Shell Small | Size is 16x16 pixels as defined by Windows and cannot be changed. |
System Large | Size is defined by the video driver, usually 32x32. |
System Small | Size is derived from the size of window captions. The caption size can be adjusted from the Appearance tab in the Display Properties dialog. |
Windows displays these sizes in different areas:
Size | Where Used |
Shell Large | On the Desktop, and in Large Icon views of Explorer and open folders. |
Shell Small | On the Start menu, and in Small Icon, List and Details views of Explorer and open folders. |
System Large | In <ALT><TAB> dialog (also known as "Cool Switch"). |
System Small | Title bar (caption) of application windows. |
