Is a 2.1 650b tyre closer in height to my 2.5 DH tyres than a 2.1 26"?

I'm getting a hardtail made around a Pinion gearbox. Due to Pinions broad range of gears, this bike will be my long ride bike(talking hours not days), but still want to do all the other thing you do on a hardtail. So not knowing how tall the tires are, I'm wondering if they're pretty close to my 26" DH tires circumference anyway. Can anyone rocking a 2.1-2.3 650b tyre please measure the height. Guessing a 2.1 26"er will be closer, but doubting there'll be much in it.
