Understanding Aspect Ratios

Aspect ratio describes the proportional relationship between a display's width and height. It's expressed as two numbers separated by a colon (width:height) and determines the shape of your screen.

Common Monitor Aspect Ratios:

16:9 - Standard widescreen (1920×1080, 2560×1440, 3840×2160)
21:9 - Ultrawide (2560×1080, 3440×1440)
32:9 - Super ultrawide (3840×1080, 5120×1440)
16:10 - Professional displays (1920×1200, 2560×1600)
4:3 - Legacy square monitors (1024×768, 1600×1200)
5:4 - Old professional (1280×1024)

Why Aspect Ratio Matters:

• Determines content compatibility and letterboxing
• Affects productivity and multitasking efficiency
• Influences gaming field of view and immersion
• Important for professional video/photo work
• Impacts desk space and ergonomic setup
