Working with Units & Rulers

While changing the measurable units and rulers do not affect output quality, they do help to measure information in a document consistent with the specific output device. Ruler Units give you precise information on the width and height of the active document. The Column Size measurements provide information that Photoshop needs to create documents with columns, such as newspapers, magazines, brochures, etc. The New Document Preset Resolutions area lets you select specific resolution values when creating new documents. Insert the values you’ll use most often in the creation of a new Photoshop document.

Work with Units & Rulers Options

  • yellow_1.jpg Click the Edit (Win) or Photoshop (Mac) menu, point to Preferences, and then click Units & Rulers.
  • yellow_2.jpg Select the Units options you want to use:
    • Rulers. Sets a default measuring system for the Ruler bar.

      For example, pixels would be most common for images displayed on a monitor, and picas or inches most common for output to press or printer.

    • Type. Use to measure type with pixels, points, or millimeters.
  • yellow_3.jpg Select the Column Size settings you want to use:
    • Width. Choose a measurement system and numerical value for column width.
    • Gutter. Choose a measurement system and numerical value for gutter (the space between the columns).

      When you choose a measurement system (points, inches, or centimeters), Photoshop changes the value to correspond to the type of measurement system.

  • yellow_4.jpg Select the New Document Preset Resolutions settings you want to use:
    • Print Resolution. Select a print resolution and measurement value for default printing.
    • Screen Resolution. Select a print resolution and measurement value for default screen display.
  • yellow_5.jpg Click the PostScript or Traditional option measuring systems for Photoshop’s type tool (PostScript is the most widely used).
  • yellow_6.jpg Click OK.
