As a mobile app developer, we need to consider various screen sizes for a wide range of Android devices.
Here’s a quick note of recommended image sizes for Android app icons:
36×36 for low-density (LDPI)
48×48 for medium-density (MDPI)
72×72 for high-density (HDPI)
96×96 for extra high-density (XHDPI)
180×180 for extra extra high-density (XXHDPI)
192×192 for extra extra extra highv-density (XXXHDPI)
Image Scaling
Source: Units and measurements – Layout – Google design guidelines
Images can be scaled to look the same across different screen resolutions by using these ratios:
| Screen resolution | dpi | Pixel ratio | Image size (pixels) |
| xxxhdpi | 640 | 4.0 | 400 x 400 |
| xxhdpi | 480 | 3.0 | 300 x 300 |
| xhdpi | 320 | 2.0 | 200 x 200 |
| hdpi | 240 | 1.5 | 150 x 150 |
| mdpi | 160 | 1.0 | 100 x 100 |
For our reference. 🙂
