Size of folders displayed in Mac

One, look at the folder size in the Finder:

1. Cmd+a Select all files in the current directory

2. In the right-click menu, select "Show Options" or press Cmd+j shortcut key

3. Select the check box for "Calculate all sizes"

The size of the folder will then be displayed.

Second, in terminal view the current directory of all files (including folder) Size:

DU-HS *

Or:

DU-SHC *

The second command displays a total size at the end, which is the overall size of the current directory.

Reference: What command combo at terminal would output a list of directories with human-readable sizes?
