Currently it's not possible to specify a marker size using MarkerOptions, so your only option is to rescale your Bitmap before setting it as your marker icon.

Creating the scaled Bitmap:

int height = 100;
int width = 100;
BitmapDrawable bitmapdraw = (BitmapDrawable)getResources().getDrawable(R.mipmap.marker);
Bitmap b = bitmapdraw.getBitmap();
Bitmap smallMarker = Bitmap.createScaledBitmap(b, width, height, false);

Using smallMarker as the marker icon:

map.addMarker(new MarkerOptions()
        .position(POSITION)
        .title("Your title")
        .icon(BitmapDescriptorFactory.fromBitmap(smallMarker))
);
