Resizing

In order to change the display or print dimensions of your image, you need to resize it. Do this by going to Image >> Image Size, and entering the desired dimensions in either the pixel dimension (for computer display) or document size (for print) area of the dialog box (Figure 10).  

You will notice when you adjust the numbers in the pixel dimension area, the document size numbers adjust automatically (and vice-versa). This is because pixel and print size are related, and affect one another. You may find it necessary to have one image sized optimally for computer display (from the original), and another copy of the image sized optimally for print (also from the original).

Selecting "Constrain Proportions" will ensure that adjustments to width will automatically adjust the height proportionally, and vice-versa, so that your image doesn't become distorted.
