Frequently asked questions
What is 4:3 aspect ratio?
4:3 means 4 units of width for every 3 units of height (about 1.33:1). It was the standard for CRT TVs and early monitors and is still used for tablets, retro gaming and Micro Four Thirds photography.
Why do old videos have black bars on widescreen TVs?
4:3 content is taller than a 16:9 screen. When displayed on a widescreen TV, the video is pillarboxed (black bars added on the sides) to avoid stretching the image.
Is 4:3 better for photography?
It depends on the subject. 4:3 suits portraits, documents and tablet displays because it is closer to natural vision, while 16:9 suits landscapes and video.
