Show Finder Folder Size

The Finder’s list view is my favorite way to view the folders and files within the macOS Finder, because it provides a wealth of information via columns that can be sorted on.

One thing that you won’t find when using the Finder’s default list view is the cumulative size of the Folders contained within. But there’s an easy way to view the sizes of Folders directly within the Finder; watch our video tutorial to see how.

How to view the size of folders within the Finder’s list view

Step 1: Open Finder

Step 2: In the menu bar select View → as List

Step 3: In the menu bar, select View → Show View Options

Step 4: Check the box next to Calculate all sizes

Doing this will replace the double dash that normally appears under the size column for folders. No more will you be required to perform a Get Info command in order to view the size of the folders within the Finder’s list view.

Along with the Calculate all sizes option, you can also choose to use the Always open in list view option to force the Finder window use list view upon opening. Since list and Cover Flow views are the only views where these info columns appear, you may consider it best to open Finder windows in list view by default.

You may also want to take another step and set the updated Finder view as the default option across all Finder windows. To do so, click the Use as Defaults option at the bottom of the View Options. Note: I’ve had mixed success with setting Finder view defaults, so your mileage may vary.
