For
Kagome
And for
Sesshoumaru
Hope this helps ^_~
I personally, however, usually write Sesshoumaru to be about 6'1"... but that's just because I dig tall guys and I can write them however the heck I feel like it lol.
For Kagome I do tend to keep her petite, anywhere between 5'1" and 5'4".
I'm pretty tall myself at 5'7", and since I freaking hate it when the guys I date (or the guys that try to date me) who are either shorter than me or at eye level. When I picture it in my head, I just think it's so much more cute (at least to me) when the guy is taller than the girl, because then it's easier for her to rest her head on his chest, rather than strain her neck craning down to rest her forehead on his shoulder because his chest is too far down to reach.
Lol, I dunno. I guess I just write them how I like them rather than how they may actually be.
