Frequently Asked Questions

What PPI is a 1080p 6-inch phone?

About 367 PPI — diagonal pixels (2203) divided by 6 inches. Above ~300 PPI individual pixels vanish at normal viewing distance.

Is higher PPI always better?

Up to a point: beyond 400 PPI returns diminish while battery cost grows. Compare candidate phones here instead of trusting marketing numbers.

How do I find my screen specs?

Resolution lives in display settings; diagonal size is the marketed inches (measure corner to corner). Enter both for the true density.

Do my screen specs leave the device?

No — math runs locally in your browser. Nothing leaves your device.
