If image or PDF files aren’t the correct size

If an image or PDF file’s size on your screen is different from its actual size, even though you’re viewing it at 100% scale, your display’s resolution may be different from the image or PDF file’s. For example, an image that’s 3 inches by 4 inches may not be that size on your display. Or, after you buy a display with a different resolution from your older one, a PDF file may appear to be a different size than it did before.

Preview can display image and PDF files at their actual sizes, regardless of your screen’s resolution.

To display images and PDF files at their actual sizes:

Step 1

Choose Preview > Preferences.

Step 2

To display images at their actual sizes, click Images and select “Respect image and screen DPI for scale.”

Step 3

To view PDF files at their actual sizes, click PDF and select “Respect screen DPI for scale.”
