Select the image in Finder, press Command+I, and look at “Dimensions” in the “More Info” section. To see the dimensions in the right-click menu, and copy them with a click, use [Supercharge](https://sindresorhus.com/supercharge).

## With Supercharge

1. Open the settings of [Supercharge](https://sindresorhus.com/supercharge), click “Tweaks”, and click “Configure…” next to “Context menu items”.
1. In the “Main Menu” tab, turn on “Image/Video Dimensions”.
1. Right-click an image or a video in Finder. The menu shows its dimensions, like “1920×1080”. Click them to copy them.

It shows when you right-click one file. The right-click items cannot show in synced folders, like iCloud Drive and Dropbox.

## Without an app

1. Select the image in Finder, and press Command+I.
1. In the Get Info window, open “More Info”. “Dimensions” shows the width and the height in pixels.

You can also choose “View › Show Preview” in Finder, which shows the dimensions of the selected image next to the files. The built-in ways are good for a quick look. Supercharge is faster when you check images often, or need to copy the size.
