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)
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. 🙂
