DPI is a Dick Proportionality Index calculator. You enter your height, weight, and penis length, and it calculates whether you are proportionately big, small, or just right.

The Rig It! feature is great for pranking your friends! Use it to trick them into thinking they are ridiculously small! A sure laugh!*

Once you have calculated your score you can post it to Facebook! Let the world know your DPI!

*Use responsibly: High risk of demoralizing effects.
