4:3 Aspect Ratio
4:3 (four-to-three) was the standard for television and computer monitors from the 1930s through the early 2000s. It produces a nearly square rectangle that matches the proportions of 35mm film frames. While largely replaced by 16:9 for video, it remains relevant for iPad displays, PowerPoint presentations, and certain photography formats.

Frequently Asked Questions
What is the 4:3 ratio in pixels?+
Common 4:3 pixel dimensions include 640×480 (VGA), 800×600 (SVGA), 1024×768 (XGA), and 1280×960. Any resolution where width ÷ height = 1.333... follows the 4:3 ratio.
Does anyone still use 4:3?+
Yes. The iPad uses a 4:3 display (2048×1536 on Retina models). Many PowerPoint templates, DSLR cameras, and legacy surveillance cameras also use 4:3. It is less common for video but still relevant for static images and presentations.
What is the difference between 4:3 and 16:9?+
4:3 is more square (ratio of 1.33:1) while 16:9 is wider and more rectangular (ratio of 1.78:1). 16:9 is the modern TV and video standard; 4:3 is the legacy standard that preceded it. When viewing 4:3 content on a 16:9 screen, black bars (pillarboxing) appear on the sides.
