height in a boulevard

[alegna]

Ds is getting close to outgrowing his blvd rf by height.  I need to really assess how close he is, but the blvd is SUCH a pain for this.  Once upon a time I saw a cool picture where the lines were drawn in, but now I can't seem to find it.  Or if anyone has some great easy way to decide how much more space he has I'm all ears.
