# How do I sort files by size in Finder?

Switch the window to list view (**View → as List**, or Command-2) and click the **Size** column header; click it again to reverse the order. If there's no Size column, Control-click any column header and tick **Size**.

Folders show two dashes instead of a size until you turn on **View → Show View Options → Calculate all sizes**. With that on, folders sort by their real size too, though big folders can take a moment to measure.

To sort a whole disk rather than one folder, use a Finder search instead: [find large files on your Mac](https://storagestudio.us/faq/mac-storage-basics/how-do-i-find-large-files-on-my-mac).
