What is DP in Android?

DP (density-independent pixel) is a virtual unit that scales with screen density. It ensures consistent UI across all Android devices regardless of screen size.

DP to PX Formula

px = dp × (dpi ÷ 160)

  • mdpi (160dpi): 1dp = 1px
  • hdpi (240dpi): 1dp = 1.5px
  • xhdpi (320dpi): 1dp = 2px
  • xxhdpi (480dpi): 1dp = 3px
  • xxxhdpi (640dpi): 1dp = 4px
SP ↔ PX Converter
Convert scale-independent pixels (used for text sizes) to screen pixels.

What is SP in Android?

SP (scale-independent pixel) is like DP but also scales with the user's font size preference. Always use sp for text sizes in Android.

Hex ↔ RGB Converter
Convert color hex codes to RGB values and vice versa — useful for Android color resources.
