Для меня чертовски забавно из раза в раз видеть то, как люди повторяют одни и те же стереотипы по поводу роста самых огуречных(после Императора кочено же) варпо-генно сотворённых персонажей сорокотысячника.
То Вулкан для всех самый высокий после Магнуса просто потому что, без причины.
То Хорус один из самых высоких точно так же - просто потому что.
То кто-то худо-бедно услышал "Мортарион один из самых высоких", и тоже особых оснований не видать.

Посему мною была сделана банальная разведка по комментариям в Реддите и вот что мне удалось собрать о росте Примархов, столь любимыми всеми и ненавистными мною:

Лев чуть ниже 3 метров
The Lion was a truly imposing physical specimen. A giant, standing at a little under three metres tall, it was impossible to escape the suspicion that he had been cut from a broader canvas than the majority of men. His body was perfectly proportioned and entirely in scale with his height. He was powerfully built, lithe yet muscular.
— Descent of Angels

Лоргар почти 3 метра
Lorgar looked magnificent, near three metres tall and clad in custom-made purplish-grey robes that shimmered with silken threads, a halo of gold fixed about his brow. Ostentation that he was not proud to bear but was demanded of him by custom and the expectations of the masses. On the far side stood Archdeacon Kor Phaeron, as malignant and destructive as the day Nairo had first met him, but safe within the shadow of his adoptive son.
- Bearer of the Word

Лев чуточку выше Гиллимана, второй только-только заметил. Считай одного роста.
‘Satisfied?’ asked the Lion, tossing the axe back to him.
‘Honour is satisfied, lord,’ Faffnr assented, catching it. He nodded and backed off, waving to his pack to do the same. Holguin and Redloss both grinned with unbearable insouciance.
‘Then tell Bo Soren to guard his manners, Faffnr,’ Guilliman said over his shoulder without looking back.
‘I will, Jarl,’ Faffnr returned. Guilliman heard a hard slap and a muffled curse.
He looked at the Lion. He’d never realised before that the Lion was very slightly taller than him.
‘Shall we, brother?’ he asked.
‘The famous Fortress of Hera?’ asked the Lion. ‘I would be disappointed not to see it.’
- The Unremembered Empire

Хан чуть выше Хоруса
Where the Khan had been hard to deal with, Horns was overwhelming. The two primarchs were of similar build - the Khan might even have been slightly taller - but it was obvious to me why Horus had been chosen to be the Emperor's instrument; the dynamism of his gestures, the openness in his face, the sense of effortless power that cascaded from his ornate armour and spilled out across the room. Even amidst the inexplicable dread that reached up to choke me, I understood why men worshipped him.
- Broterhood of the Storm

Хан выше Русса почти на голову
They faced one another, Wolf King and Warhawk, separated by silence.
‘Do you know, my brother, how many of my sons died at Alaxxes?’ Russ growled eventually, forcing the words through clenched teeth.
When the reply came, the Khan’s voice was as it ever had been – resonant, heavily accented, measured. ‘We had to be sure,’ he said.
‘Sure.’ Russ closed the gap between them, keeping his blade unsheathed. The Khan was almost a head taller, yet leaner, and carrying deep wounds. At the edges of the throne-dais, a hundred bolters remained trained on the White Scars’ master, but neither primarch paid them any heed. ‘And did you find that surety? Do you still name me the Butcher of Prospero?’
- The Path of Heaven

Хан чуть выше Мортариона
Mortarion took a few steps towards the Khan. Qin Xa moved to intervene, but the Khan gave him a wordless battle-sign, and he retreated with the others. The two primarchs stood alone, shadowed by their respective bodyguards.
Mortarion was a little broader, the Khan a little taller. Mortarion’s armour was heavy, almost crude, where the Khan’s was fine-wrought. Silence was a gigantic weapon forged from a chunk of adamantium and glittering with archeotech fixings; the Khan’s dao was a slender, perfectly curved piece of flawless metal, deriving its strength from its form rather than its size. It could be made to move faster than any blade in the Imperium.
- Scars

Ангрон ростом с Хоруса
"Loken had seen the primarch of the World Eaters before, but was still awed by his monstrous, physical presence. Angron was huge, easily as tall as the Warmaster, but also massively broad, with wide hulking shoulders like some enormous beast of burden."
- Galaxy in Flames

Русс чуть ниже Вальдора
Russ drew up to Valdor then. He was a little shorter, much broader, his armour stained and smeared where Valdor’s was pristine. ‘Oh, yes,’ he hissed, smiling in a disconcertingly feral manner. ‘I can smell him now. I can smell him hunkering down in his own filth, fearful of me.’
- Magisterium

Феррус Манус на голову выше Корвуса и Вулкана
Ferrus Manus, clad in his shimmering fuliginous armour, stood a head taller than his brothers, pacing like a caged Medusan snow lion as he awaited news of the rest of his Legion. He punched onesilver fist into his palm as he paced, and Balhaan could see the urgent need to take the fight to the traitors in his every movement.
Next to the broad, mightily muscled Primarch of the Iron Hands, Corax of the Raven Guard was tall and slender. His armour was also black, but it seemed to be utterly non-reflective, as though it swallowed any light that dared to fall upon it. The white trim of his shoulder guards was fashionedfrom pale ivory, and great wings of dark feathers swept upwards to either side of his pallid, aquiline features. His eyes were murderously dark coals, and long, gleaming talons of silver were unsheathedover his gauntlets. So far, the Primarch of the Raven Guard had said nothing, but Balhaan had heardthis of Corax, that he was a taciturn warrior who kept his counsel until he had something of worth to impart.
The third of the primarchs was Vulkan of the Salamanders, a brother with whom Ferrus Manus had a great friendship, for both were craftsmen as well as warriors.
- Fulgrim

Кёрз выше Льва и Жиллимана - без уточнения, на сколько
‘Then I rejoice,’ said Guilliman, ‘but I believe it is past time that the heretics paid a price. A blood price. I think it is past time that a devoted son put a heretic in the damned ground.’
‘Agreed, sevenfold,’ said the Lion in a low, hunting voice. Curze faced them. He stood tall, taller than either of them – a stark figure of lean, long bones and hollowed frame. He looked like a starved giant, towering yet emaciated.
- Unremembered Empire

Все знают, что Магнус самый высокий. Но обычно все уточняют, что он меняет свой рост при помощи псайкерства, посему, мол, вне списка.
Просто в кодексе ТС поставлено так, будто он по чистой физухе будет выше остальных Примархов. Не то чтобы это было бы прям важно, но всё равно.

Магнус выше Императора
A GIANT STANDS with the Emperor – a figure robed in the azure of off-world oceans. One eye stares down at the kneeling figure. The other eye is lost, a scarred crater marking its lack.
‘Greetings, Lorgar,’ says the muscled giant. He is taller even than the God in Gold, and his long hair is styled in a scarlet mane, like that of a prideland lion. ‘I am Magnus. Your brother.”
- First Heretic.

Магнус был создан как гигант, физически и ментально возвышающийся над его братьями
Magnus was created by the Emperor of Man as a giant, physically and mentally towering over his fellow Primarchs. His abilities as a psyker were unsurpassed by all save the Emperor himself, and with honour and cunning he led the Thousand Sons to countless victories in the Great Crusade.
- Codex: Thousand Sons 8ed

Альфарий - отдельный мем. Есть противоречие: то он как Гиллиман, то самый низкий. В принципе из Индекса Астартес история подаётся, по всей видимости, как легенды внутри Ордена Ультрамаринов. Оно ещё и старее по году выпуска, так что скорее всего книги вышедшие после перевешивают информацию из Индекса.

Альфарий более чем на фут выше Лунных Волков, будто бы того же роста с Хорусом(но о росте ли речь?), и одного роста с Гиллиманом

"...but the last man was different. More than foot taller even than the Luna Wolves Space Marines, he had piercing green eyes and looked almost a match for Horus himself."

"...our great Lord and Primarch Roboute Guilliman himself strode forward, ignoring the melee around him, straight towards Alpharius. The two Primarch's stood before each other. They were equal in stature."

- INDEX ASTARTES IV "The Enemy Within - The Alpha Legion Space Marine Legion" (2004)

Альфарий почти на голову ниже остальных братьев, в целом их в этой сцене восемь (Хорус, Лоргар, Магнус, Мортарион, Ангрон, Кёрз, Пертурабо, Альфарий) где Магнус, Мортарион, Кёрз и Альфарий - проекции.
Alpharius was the last of those present through long-range sending. He stood helmed, while all others were bareheaded, and his hololithic image was stable while each of the others suffered corruption from the vast ranges between their fleets. Alpharius, almost a head shorter than his brothers, stood scaled in crocodilian resplendence, his reptile-skin armour plating glinting in the false light of his manifestation. His salute was the sign of the aquila, the Emperor’s own symbol, made with both hands across his breastplate.
- AURELIAN (October 2011)

Альфарий самый маленький из Примархов
Alpharius had spent time with Horus before – when loyal to the Emperor and since – and never before had he felt threatened. This time was different. Horus seemed bigger than ever. Alpharius was the smallest of the primarchs, but had not allowed this to undermine his confidence. Now that he looked at Horus, tree-trunk-thick arms stretching the fabric of his robes, Alpharius realised that his fellow primarch could crush him, tear him limb from limb, without warning.

+++ ВНИМАНИЕ +++
Учитывая чудовищно скудное количество информации, не надо излишне бросаться мерить, какая информация тут "чище" или "правдивее" из-за того, что многие указания роста подаются с точки зрения мыслей посторонних. И тем более забейте на счёт доспехов - их влияние на рост нигде ни разу даже вскользь не упоминается, и авторам точно плевать на такие тонкости.

+++ ИТОГИ +++
А итогов в итоге и не будет. Всех перечисленных данных выше не хватает, чтобы создать цельную цепочку разницы роста. Но я всё равно сделаю парочку

1) Скорее всего рост Примархов варьируется очень незначительно. Самый широкий спектр, который можно вывести, это Русс-Мортарион-Хорус-Хан. Где Хан на голову выше Русса, что в целом достаточно, чтобы Руссу приходилось поднимать голову для взгляда Хану в глаза, но не то чтобы огромная разница. И тем более недостаточно, чтобы представлять Русса каким-то коротышкой, как многие любят. По этой же логике Альфарий может быть всего на какой-нибудь 1 дюйм (2,5см) ниже условного Русса. И всё равно быть "более чем на фут выше Лунных Волков".

2) Не надо придумывать безумные цифры для их роста. Учитывая, что Лоргар, Лев и Гиллиман плюс минус 3 метра ростом (10 футов), то не стоит прыгать до безумных 3,5 метра и тем более 4 метра. 3,7 метра это уже Дредноут Кастраферрум, если что.

Вот так вот.
Если у вас есть другие указания о росте Примархов - я буду очень рад их увидеть и пополнить этот список. Здесь огромное поле для затыкания белых пятен - Дорн, Сангвиний, Вулкан, Пертурабо, Коракс, Фулгрим. Да и на Мортариона бы ещё найти не помешало.

В следующих статьях, скорее всего, накидаю информации о росте Астартес-Примарис-Кустодес, и о "безгильзовости" болтеров.
