What is the 4:3 Aspect Ratio?
The 4:3 aspect ratio was the standard for CRT televisions and early computer monitors. It is slightly wider than tall – 4 units wide for every 3 units tall.
While 16:9 has largely replaced 4:3 for video and monitors, it is still used for some projectors, presentations, and legacy content.
If you're working with older equipment or creating slides for a projector, 4:3 remains a relevant format.
