How do I find the size of a project in Photoshop?

Published in Photoshop Image Size 2 mins read

To find the size of your project in Photoshop, which typically refers to its dimensions and resolution, you need to access the Image Size dialog box. This feature provides key information about your document's physical size, pixel dimensions, and resolution.

Accessing the Image Size Information

Photoshop provides a dedicated dialog box to view and modify the size properties of your image.

  • Step 1: Open your project in Photoshop.
  • Step 2: Navigate to the menu bar at the top.
  • Step 3: Click on Image.
  • Step 4: Select Image Size from the dropdown menu.

Alternatively, you can use a convenient keyboard shortcut:

  • Windows: Press Ctrl + Alt + I
  • macOS: Press Command + Option + I

What Information is Displayed?

Once the Image Size dialog box opens, you will see several important metrics about your project's size. These typically include:

  • Pixel Dimensions: The width and height of your image in pixels. This tells you how many pixels make up your image horizontally and vertically.
  • Document Size: The physical dimensions (e.g., inches, centimeters, millimeters) and the resolution. This shows how large the image will appear when printed or placed at that specific resolution.
  • Resolution: The number of pixels per unit of measurement (commonly pixels per inch, or ppi). As noted in the reference, "The resolution value is displayed in pixels per inch (ppi) in the Image Size dialog box."

Here's a simple representation of the key information you'll find:

Metric Description Unit Example Found In Dialog Box?
Pixel Dimensions Total pixels wide by total pixels high pixels Yes
Document Size Physical width and height at a given resolution inches, cm, mm Yes
Resolution Pixels per unit of physical measurement ppi (pixels/inch) Yes

Understanding these values is crucial for both digital and print workflows. Pixel dimensions are key for screen display, while document size and resolution are critical for print output quality.

This dialog box is your primary tool for understanding the dimensional and resolution "size" of your Photoshop project.
