Android dip Ruler

« Print it, cut it, give it to your designer! »

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
