There are a few ways to make the ruler visible in Photoshop. One way is to use the Ruler tool, which is located at the bottom of the Tools palette. The Ruler tool can be used to draw lines and shapes, as well as create rulers for text and images. Another way to make the ruler visible is to use the Marquee tool, which is located at the top of the Tools palette. The Marquee tool can be used to select a part of a image or text, and then drag it around so that it changes its size.
