The Zoom Level Indicator
Located at the lower left corner of the document window, the zoom indicator shows the magnification level of the document. You can swipe your cursor in here and type a new number to change the zoom level. Go ahead and try it now.
To return your document to 100% magnification, locate the zoom tool in the toolbox and double click the button. The keyboard equivalent to this shortcut is Ctrl-Alt-0 (Win) or Cmd-Option-0 (Mac).
Status Bar
To the right of the magnification display on the status bar, you will see the document dimensions displayed. This shows the print size of the file and its resolution.
Status Bar Display Options
Next to the Document sizes display there is a small black arrow that pops up a menu. This menu controls what is shown in this area of the status bar. In addition to Document Dimensions, you can optionally choose to display Document Sizes, Document (Color) Profile, Scratch Sizes, Efficiency, Timing, or the name of the current tool. To learn more about each of these items, look up "To display file information in the Info palette or status bar" in Photoshop's online Help.
