The Timeless Appeal of 4:3: Why the Classic Aspect Ratio Still Matters in a Widescreen World

We live in an era dominated by ultra-wide displays, cinematic widescreen formats, and vertical video designed for quick scrolling. Yet, tucked away in the settings of our smartphones, retro gaming consoles, and professional photography gear lies a format that predates digital media entirely: the 4:3 aspect ratio (often expressed as 3:4 when in portrait orientation).

While widescreen formats like 16:9 often feel like the default standard for modern entertainment, the 3:4 aspect ratio continues to command a loyal following among creators, photographers, and nostalgists alike. But what is it about this boxier, more balanced frame that refuses to fade into obsolescence?


What is a 3:4 Aspect Ratio?

An aspect ratio describes the proportional relationship between an image’s width and its height. For a 3:4 ratio (in portrait), for every 3 units of width, there are 4 units of height. (Conversely, in landscape, it is written as 4:3—four units wide by three units high).

To put it into perspective:

  • 16:9 (Widescreen): Much wider than it is tall, mimicking human horizontal peripheral vision.
  • 4:3 / 3:4 (Standard/Classic): Taller and squarer, closely resembling a traditional photographic print or a standard canvas.

A Brief History: From Film to Television

The 4:3 aspect ratio’s roots stretch back to the very dawn of motion pictures. In the 1900s, inventors like Thomas Edison and William Dickson standardized 35mm film with an aspect ratio of roughly 4:3 (specifically 1.33:1). When television broadcasting emerged decades later, engineers adopted this exact format because it fit standard cathode-ray tube (CRT) screens efficiently.
