  3. In the Properties window, under the File tab, the width and height are listed next to Video size: listing. For example, 640 x 480 is 640 width and 480 is the height. You'll also see other information such as the length, bit rate, aspect ratio, audio codec, and video codec of the video file.

Apple QuickTime

To view the dimensions of video files such as .mov files that play through Apple QuickTime, follow these steps.

  1. Open the movie file in Apple QuickTime.
  2. Click the window and then click Show Movie Info.
  3. In the Movie Info section, the Normal Size and Current Size displays the dimensions of the video file. For example, 320 x 240 is 320 width and 240 height.
