# How do I see folder sizes in Finder?

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.

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

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](https://storagestudio.us/manual/whats-using-space).
