Magnus was only a giant through psychic means, when fighting Russ the image disappeared (As well as Russ' unconcious one) showing both to be of equal height and looking very ragged.

Alpharius Omegon were a head taller than their legionnaires, and the Alpha Legionnaires were the tallest of all Astartes, as tall as the Custodes.
