Which ratio describes NTSC's traditional frame shape?

Explanation:
The aspect ratio describes how wide the picture is compared with its height. NTSC was designed around displays that were roughly square, so the traditional frame shape uses a 4:3 ratio. That means for every 4 units of width, there are 3 units of height, producing the familiar almost-square look of classic SD television. Widescreen formats like 16:9 came later with HDTV, while 1:1 is a square, and 9:16 is a tall portrait orientation. So the ratio that best matches NTSC’s traditional frame is four by three.
