I found that out the hard way, too! I bought the Elfdoll 'Mir' sculpt and it's a perfect SD sized head. Yay. (I need all the heads to be similar sized, because they're part of a 'seiyuu' group where the dolls are all in scale to each other.)
Then, I saw an Elfdoll Won head that I thought would be great for a particular seiyuu. I bought it, never even IMAGINING it wouldn't be the right size. It's SD after all, right?
Wrong! When I received him, he was super, super tiny! I couldn't use him at all! It was more like an MSD sized head.
So, then I resold it, and looked around some more. Elfdoll has a lot of Asian looking sculpts, so I ended up liking the 'Wu' head next. But now, I was paranoid it too would be too small!!!
I asked the seller if the Wu was more like the Mir size or the Won size. (Luckily, she had owned all three at one time!)
She said it was more like Mir, though not quite as large.
I figured, it's as good as I'm going to find, so I risked it.
Thank goodness, Wu IS a decent sized SD. A TEENY bit smallish, but hardly noticeable.
I just couldn't believe the 'Won' head---so small!
The same thing happened with Angelsdoll, too. I bought 2 heads (both SD) and when I got them one was gigantic and the other almost MSD sized. ^^;;
So I guess, even within companies, the head sizes can vary!
