Decent backgrounds for various things?

[KaelemGaen]

I was wondering if there are any backgrounds for Make Human that I can use to get an idea of scale when working with the sliders? The background Grid still seems a bit to arbitrary to me and I wanted something that would put a scale with measurements next to it. I tried making a very short shape that wasn't a child but I had no decent scale of reference besides the Measurements in the bar at the bottom. I'm more visual when it comes to that stuff...

I couldn't think of a better title I'm sorry.

TL;DR
Any backgrounds for Size comparison at a glance?
