According to jbofi'e, that's not grammatical either. I'm trying to join the 
bridi-tails. Is there a way to do that in afterthought?

One possible interpretation is "It measures nine inches, or one foot and nine 
inches, or three feet and nine inches, or so on, but not two feet and nine

nine inches (as long as the gram isn't two feet long).
