What is the best aspect ratio for mobile phones?

19.5:9 (Most Balanced)

• Used by: iPhone 14/13/12, many Samsung Galaxy models
• Best for: General use, one-handed operation, vertical content
• Pros: Comfortable width, good screen-to-body ratio, optimal ergonomics

20:9 (Slightly Taller)

• Used by: Google Pixel, OnePlus, many Android flagships
• Best for: Maximum scrolling space, vertical content consumption
• Pros: Even more screen space, excellent for social media, narrow for easier grip
• Cons: Noticeably tall, more black bars on video
