No one carries around a tape measure when photographing.
You are kinda working backwards. You need to work out which lens do what, rather than worry about dof scales.
For example, if someome has a largish face and you want to flatten it somewhat, you can shoot them with say a 200mm lens. Whether the left eye is slightly softer than the right is not really a big deal as long as the closest eye is in focus.
How the face looks is more important!

Hmmm...
I know which lenses I want to use... (50mm and 85mm on DX sensor)
What I wanted to know was how shallow the depth of field is with those lenses at a typical shooting distance with particular apertures
...and no, I wasn't going to use a tape measure!! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='' />
