This guide includes a complete iPhone size chart, screen dimensions, display resolutions, and recommendations to help you find the right iPhone size in 2026.
Why iPhone Screen Size and Resolution Matter

For developers and designers, understanding screen dimensions helps:
- Create responsive interfaces.

Understanding Key Display Terms
Screen Size
Screen size refers to the diagonal measurement of a display, measured in inches from one corner to the opposite corner.
Resolution
Resolution is the number of pixels displayed on the screen horizontally and vertically.
Common resolution standards include:
- HD: 1280 × 720 pixels
- Full HD: 1920 × 1080 pixels
- QHD: 2560 × 1440 pixels
- 4K UHD: 3840 × 2160 pixels
Pixels (px)
Pixels are the smallest visible units that make up an image on a digital display.
Points (pt)
Points are Apple’s logical measurement units used in iOS interface design.
Pixels Per Inch (PPI)
PPI measures pixel density. Higher PPI values generally produce sharper text and clearer images.
