The most flexible way to set thumb size for me is to create layered-drawable with shape as placeholder

thumb_image.xml

:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape>
<size
android:height="40dp"
android:width="40dp" />
<solid android:color="@android:color/transparent" />
</shape>
</item>
<item android:drawable="@drawable/scrubber_control_normal_holo"/>
</layer-list>

So basically changing the size of shape will stretch drawable, the shape is transparent so it won't be visible. Also the minimum size of such thumb is size of bitmap.

Here is example of layout:

<SeekBar
android:id="@+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:thumb="@drawable/thumb_image" />

<SeekBar
android:id="@+id/seekBar2"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
