How to Use This Calculator

  1. Select whether to calculate from width or height.
  2. Enter the known dimension (width or height).
  3. The calculator displays the corresponding dimension maintaining 4:3 ratio.
  4. Use this for older displays, legacy content, or specialized applications.

4:3 Aspect Ratio Formula

Dimensions are calculated from the aspect ratio:

Ratio = 4 / 3 = 1.333...
Height = Width / 1.333...
Width = Height × 1.333...

Example: 1600 width: Height = 1600 / 1.333... = 1200. Result: 1600×1200 (4:3). 1200 height: Width = 1200 × 1.333... = 1600. The 4:3 ratio was the standard for older displays and is less common in modern widescreen formats.

Full Description

The 4:3 Aspect Ratio Calculator helps you calculate dimensions for 4:3 aspect ratio displays, images, or content. 4:3 is a standard aspect ratio where the width is 1.333... times the height. This ratio was the standard for older CRT monitors, TVs, and cameras, but has been largely replaced by widescreen formats like 16:9 and 16:10 in modern displays.

Common 4:3 resolutions include 1600×1200 (UXGA), 1400×1050 (SXGA+), 1280×960, 1024×768 (XGA), and 800×600 (SVGA). The ratio is calculated as Width / Height = 1.333... If you know the width, height = width / 1.333... If you know the height, width = height × 1.333... The calculator automatically maintains the 4:3 ratio when calculating dimensions.

This calculator helps you determine 4:3 dimensions. Enter width or height, and it calculates the corresponding dimension. Use it for older displays, legacy content, specialized applications, or understanding 4:3 aspect ratio. While less common now, 4:3 is still used for some specialized displays and older content formats!

Frequently Asked Questions

What is 4:3 aspect ratio?

4:3 is a standard aspect ratio where width is 1.333... times the height. It was the standard for older TVs, computer monitors, and cameras. Common resolutions: 1600×1200, 1400×1050, 1280×960, 1024×768. Less common now but still used for some displays and older content.

How do I calculate dimensions?

If you know width: Height = Width / 1.333... If you know height: Width = Height × 1.333... Example: 1600 width: Height = 1600 / 1.333... = 1200. 1200 height: Width = 1200 × 1.333... = 1600. The calculator does this automatically.

What are common 4:3 resolutions?

Common resolutions: 1600×1200 (UXGA), 1400×1050 (SXGA+), 1280×960, 1024×768 (XGA), 800×600 (SVGA). 4:3 was the standard for CRT monitors and older displays. It's less common now but still used for some specialized displays and older content formats.

Why is 4:3 less common now?

4:3 was replaced by widescreen ratios (16:9, 16:10) because widescreen is better for movies, video, and modern content. 4:3 provides more vertical space but less horizontal space. Most modern content is produced in 16:9, so displays moved to widescreen formats.
