Bike Sizing?

therefore an equal size frame will be a little taller.

Also, the bottom bracket is higher on track frames, so to maintain comfortable crotch-clearance blah-blah..
It will be taller, but the seat height will still be the same, because you don't measure seat height by how far off the ground it is, but in a line from c of BB to top of saddle (a non-vertical line).
