The default setting in Mac OS X Finder is to display no file information, but you can easily set the Finder, Windows, and the Desktop to show image dimensions through a setting in View Options. Basically, you’ll see the complete resolution of a picture highlighted in blue underneath the file name, hugely useful for Mac users who do a lot of image work and editing.
Here’s how to enable this great feature and view the image file dimensions right from the Mac Finder.
How to Make Image Resolution & Dimensions Visible Under File Names in the Mac Finder
- Hit Command+J or pull down the View menu and choose “Show View Options”
- Select the checkbox next to “Show Item Info”
- Optional: If you want the setting to be applied to all Finder windows and folders, click the “Use as Defaults” button at the bottom, which will allow all folders to show the image information. Otherwise, this setting is just folder specific.
You’ll notice that images will immediately show their dimensions. As a side effect, other Finder objects will also display information like item count and file size. Here is what the view option looks like toggled, and the image resolution shown under a few sample files in the Finder:
In order to see the image dimensions underneath a file name, you must be viewing the files in “Icon” view of the Finder. Any other view option will not display the image dimension or file information under the file name, this is limited to the icon format only due to size restraints, that may change in a future version of OS X. Keep that in mind, because if you enable the “Show Item Info” option and don’t see the image resolution underneath a picture, you probably just need to switch back to the Mac Finder’s “Icon” view to make it visible.
This works in all versions of OS X from the earliest renditions through Mavericks, so you’ll find it supported regardless of what release you’re using.
