What is the navigation drawer icons size?

Question

I need to know the correct size (artboard and content) for Navigation Drawer icons.

It doesn't say anything on the Navigation Drawer specs: http://www.google.com.br/design/spec/patterns/navigation-drawer.html#navigation-drawer-specs

Thanks!

Answer 1

I would vote up Balar's answer, but it is off by one small detail. The correct answer is that all small icons should be 24 x 24 dp.

Answer 2

For:

mdpi : 24 x 24 px
hdpi : 36 x 36 px
xhdpi : 48 x 48 px
xxhdpi : 72 x 72 px
xxxhdpi : 96 x 96 px

According to their ratios:

mdpi : hdpi : xhdpi : xxhdpi : xxxhdpi= 1 : 1.5 : 2 : 3 : 4

Update:

Now google published Material icon design with more details.icons may be scaled down to 20dp with a trim area of 2dp surrounding the icon.
