One sec, are my judgements on height accurate? If not then I may be messing up.

Unarmoured Astartesor Astartes in Scout Carapace: 8 feet

Astartes in regular Power Armour: 9 feet (not counting battle standards, jump packs and other things that protrude above the top of the helmet)

Astartes in Centurion Suit or Terminator Armour: 11 feet

Primarchs: 12-14 feet for most (depending on which Primarch it was and whether they've got their armour on) and 20 feet for Magnus (though his height may be a psychic facade as Legion said)

Dreadnought-interred Astartes: 25-30 feet for the Dreadnought chassis

Off-topic: how tall was Empy, do we know? I always though he was around 9 feet tall but very skinny.
