There's got to be a better way than what I'll document here (AppleScript maybe?), but I don't know it and this will at least give you something to get the information.

  1. With a window at a desired size and frontmost, Command-Control-Shift-4.

  2. Move the crosshair-style cursor over the window, press the Space bar (cursor switches to a camera), then click the mouse/trackpad on the desired window.

  3. Open Preview and select File > New From Clipboard (or just press Command-N).

  4. Use the Tools menu to select Adjust Size, then (if necessary) switch the pop-up menu to the right of the image dimensions to Pixels. You can now see the window size.

That gets the information, but there has got to be a more efficient way.
