Why 4:3 Ratio Still Matters Today
The 4:3 aspect ratio was king in traditional monitors, cameras, and TVs. But it’s not “just retro”—it’s still essential for:
- Tablet screens
- Presentation slides (PowerPoint, Google Slides)
- Old-school gaming
- Print photography and some social media posts
Using the right ratio means:
- Crisp images that never stretch awkwardly
- Videos and graphics that fill the whole screen, no black bars
- Hassle-free formatting for classic platforms and new hybrid devices
How To Use This Calculator
- Input any width or height value in pixels (or cm/inches)
- Get matching dimensions for true 4:3 proportions
- No complex math—just accurate, ready-to-use results
Example:
Want a width of 1200 pixels? Enter it and get the perfect height:
Height = 1200 ÷ 4 × 3 = 900 pixels
So, 1200 × 900 is a perfect 4:3 ratio.
Formula for 4:3 Aspect Ratio
The math:
Width:Height = 4:3
So for every 4 units of width, use 3 units of height.
