Unit Rulers preferences The Unit Rulers preferences panel shown in Figure provides the following settings to define the units column sizes document resolution and point size to use in Photoshop Units The Rulers option specifies the units used for rulers and measurements in Photoshop. The Type option specifies the units used to measure all the settings used by the Type tools as well as the Character and Paragraph panels. The options are pixels inches cm mm points picas and percent where percent is in relation to the size of the image . When working in a print workflow using inches or picas is best. When working in a Web output workflow using pixels is typically best. Column Size Several Photoshop dialog boxes use column width as a unit of measurement including the New Image Size and Canvas Size dialog boxes. The columns in those dialog boxes are based on the setting here. Using columns can be very useful if you are preparing an image or multiple images that can be broken up into columns. New Document Preset Resolutions This specifies the default print and screen resolutions used when creating a new document with the File C New command from the main menu. Keep in mind that the screen resolution is important for images that are viewed on a computer such as Web images but print resolution determines the print quality and size of the printed image. Point Pica Size This allows you to set the values used to define the number of points and pica in an inch. The PostScript method defines a pica as about 1 6 of an inch and a point as about 1 72 of an inch. Applications from years ago used a different system where there were picas per inch and points per inch. You should keep this setting on Postscript unless you have a specific need to use the traditional method.
