Because I was bored, I decided to make a height chart with all of my characters on it. (Except Hisk's dragon form, which I will have to draw. @_@ So I'll make a separate one for Hisk later.)
Here is a delicious blank height chart PSD.You may have to add the .psd extension to it.
Just put your silhouettes (however you choose to make them, or if you use them at all) underneath the lines layer and you should be golden.
And a JPEG, just in caseHere is MINE:
