Checking Guage on Ribbing?

Hey There~
I am checking guage on ribbing. It is very stretchy. Do I stretch it to its capacity and then measure on let it sit as the accordian it is and measure it then? It’s quite a big difference.

Does the pattern give gauge in the ribbing or in stockinette? Most patterns will show it for st st figuring that if you get the same gauge in stockinette, you’ll get it in pattern. If it doesn’t say, stretch gently.

Thank you my dear Suzeeq~
