Ahhh. I asked an idiotic question. XD I remember reading that Shiki was almost as tall as Komachi...and then there was that height question ZUN answered...something like:
Small - Marisa, Cirno, Remilia, Flandre, etc. Average - Reimu, Alice, Patchouli, Yuuka, etc. Tall - Komachi, Yuugi, Yukari, Kanako etc.
