What is it?
This is a ruler in the Android "dip" ( Device Independent Pixel) unit [1].
You can print it, cut it and give it to your designer.

Why?
I've found that the concept of dp is not that easy to explain / understand.
Designers are used to think in pixels (especially if they also work on iOS projects).
Sometimes a picture is worth a thousand words, and so this ruler will make it immediately obvious that
the dp is a physical unit of length.
Some essential information is also present on the ruler:
- Definition of a dp
- List of Android logical densities ( ldpi, mdpi, etc.) with their properties
And of course it can also be actually used to measure things (screens…) since it is a ruler :)
Miscellaneous
- Made with Inkscape
- Available in A4 and US Letter
- The ruler is rotated in the page to reduce the risk of being larger than the printable area
- When printing, make sure to not scale the page (or force it to scale at 100%), to preserve exact sizes
