If you’re like most people, you probably use a ruler to measure distances and angles in your day-to-day work. But did you know that you can also use a ruler in Photoshop? Here’s how:

  1. Open Photoshop and create a new document.
  2. Select the rulers tool (R) from the Tools panel and drag it onto your document.
  3. Position the rulers so that they’re evenly spaced across the width of your document, and then click on one of the rulers to select it.
  4. Click on the Options bar at the top of the screen and select Ruler Options from the list.
  5. In the Ruler Options dialog box, set the following options: Width: This is the width of your ruler in pixels (px). Height: This is the height of your ruler in pixels (px). Ruler Style: This determines how your ruler will be displayed in Photoshop – either as an actual line or as a grid with squares equal to 1 px wide and 1 px high (or any other value that makes sense to you).
  6. Click OK to close the Ruler Options dialog box and return to Photoshop.
  7. To use your ruler, simply position it where you want it on your document, and then use its measurements to make adjustments to your image! ..
