Microsoft Windows users and Windows Media Player

If the above recommendation does not display the required information, view the video properties through Windows Media Player. This method only works if the video file is capable of being played in Windows Media Player.

  1. Open Windows Media Player and the video file you want to view.
  2. Click File and then Properties.
  3. In the Properties window under the File tab you should see the width and height listed next to Video size: -- for example, 640 x 480 is 640 width and 480 is the height. You should also be able to 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.
