How do I see folder sizes in Finder?

\n

Short answer: In Finder's List view, open View Options (Command-J) and tick Calculate all sizes, then sort by Size. For one folder, select it and press Command-I.

\n

In a Finder window, switch to List view (Command-2), then choose View → Show View Options (Command-J) and tick Calculate all sizes. Folders then show a size instead of "--", and you can click the Size column header to sort biggest first.

\n

For a single folder, select it and press Command-I (Get Info); the size appears after a moment.

\n

Calculating every size can take a while on big folders, and Finder can't see inside places your Mac protects. If you want the biggest folders ranked for you, with the ability to drill down level by level, Storage Studio's What's Using Space does exactly that. See What's Using Space.
