What is the aspect ratio for square video?

• A. 4:3
• B. 1:1
• C. 2:3
• D. 16:9

Answer: (B)

Aspect ratio shows how wide a video frame is compared to its height. For square video, the width and height are the same, so the ratio is 1:1. That means every frame is a square, not a rectangle. Other common formats describe rectangular frames: 4:3 is the traditional TV/early computer monitor size, 16:9 is the modern widescreen standard, and 2:3 is a common photographic format that’s taller than it is wide. So the aspect ratio for square video is 1:1.
