The Classic 4:3 Format

The 4:3 (pronounced "four-three" or "four-by-three") aspect ratio was the standard format for television screens and computer monitors for decades before widescreen became popular. Also known as the 1.33:1 ratio, this format creates a nearly square-like rectangular shape.

Common 4:3 Resolutions

• 640×480 - VGA, SD video
• 800×600 - SVGA
• 1024×768 - XGA, common for older presentations
• 1600×1200 - UXGA

Historical Significance

The 4:3 aspect ratio has its roots in early filmmaking and television production. It was established as the standard for television broadcasts and remained dominant until the emergence of HDTV with its 16:9 ratio in the late 1990s and early 2000s.

Current Applications

Despite the prevalence of widescreen formats today, 4:3 is still used in various contexts:

• Business presentations and educational materials
• Certain photography formats
• Retro-styled content
• Compatibility with older display systems
• iPad and some tablet displays
