If resolution is 1280 x 720, which dimension is 1280?

Explanation:
In resolution notation, the numbers are listed as width by height, describing how many pixels fit across and how many fit vertically. So 1280 x 720 means 1280 pixels wide and 720 pixels tall. Therefore, 1280 corresponds to the horizontal dimension (the number of horizontal pixels). The vertical dimension is 720 pixels. The total pixel count is 1280 × 720 = 921,600, and the aspect ratio is 1280:720, which simplifies to 16:9.
