Android DPI Reference: Android categorizes screens into standard density buckets: MDPI (160 dpi, 1.0x), HDPI (240 dpi, 1.5x), XHDPI (320 dpi, 2.0x), XXHDPI (480 dpi, 3.0x), and XXXHDPI (640 dpi, 4.0x). Crucial for checking splash image scaling in recovery and boot animations.

Frequently Asked Questions

What is Device Pixel Ratio (DPR)?

DPR is the ratio between physical display pixels and CSS logical pixels. A phone with a 1080x2400 physical screen and a DPR of 3.0 has a logical CSS viewport of 360x800 pixels.

How do Android display density buckets (MDPI, HDPI, XHDPI, XXHDPI) correlate to DPR?

Baseline MDPI is 160 DPI (DPR 1.0), HDPI is 240 DPI (DPR 1.5), XHDPI is 320 DPI (DPR 2.0), and XXHDPI is 480 DPI (DPR 3.0). Android selects drawable assets based on this scale.

What is the difference between screen resolution and viewport size?

Screen resolution is the total physical pixel count of the hardware monitor or smartphone panel. Viewport size is the actual active area accessible to browser web content excluding system status bars.
