Ymir was supposed to wander forever as a mindless titan, while Eren was injected with the suppose of being turned in a shifter.

Meaning that the serum Ymir got was probably of way less quality then Eren's.

Probably the shifters's serum is a concentrate, while the serum designed for the mindless is watered down.

On Armin case I am not sure he got the size of the Colossal, cause I believe that it wasn't compatible with the Colossal power, remember that it was picked up to inherit the Coordinate.

Serums are made from titan's spinal fluid, it isn't too unlogic to believe that each successor of each titan power are to be injected with the corripective serum to get a better synergy. But what about Dina then? She got injected with a normal serum yet her pure form was larger than that of Ymir and Eren.

Dina had royal blood and Marley had different types of serum for the size

About Armin I think he will get taller then normal but be shorter\weaker then Berthtold
