How precise of an answer do you think that you need?
As a general rule bicycle tires will vary slightly in diameter or circumference depending on the bead seat width of the rim they are mounted on.

This will get you heights for whatever size tire you put on. Also helpful for determining clearance.

Here's an older Google doc that captured a lot of actual 650B tire diameters: https://docs.google.com/spreadsheets...z-U/view#gid=0

OK, thanks for the answers so far. I didn't anticipate the info about rim width though. This might be a very subjective impression I have in my head but I think I feel a bit tall on my flat-bar road bike and too short on my 26" wheel mountain bike. Their tires are the following 700x32c and 26x1.75". Measuring by eye, I think they're about 66 and 69cm high.
This may seem perfectionist but I was wondering if I could find a 650b tire that would give me a height of 67.5cm which is right between the two. I was thinking of buying the Devinci Cartier which comes with 27.5x1.75" tires but I don't know the inner width of the rims. I was thinking of either getting something like the Pacenti Pari Moto, Soma B-Line, Kenda Koast or Panaracer Nifty Swifty tires (either in 35c or 38c depending on rim width).

You know, come to think of it, maybe I don't have to think about it too much anyway. I just had an experience yesterday where I took a short cut on grass (yes to avoid the sidewalk to avoid a fine) and the ground was so soft, I thought it was sucking up my energy. Well, at least with 35c tires. So I guess the 27.5"x1.75' tires on the Devinci Cartier will do anyway. Besides, it would be about the same height as the 700x32c tires on my flat-bar road bike which I find plenty fast.
