Elendil the Tall, son of Amandil (last) Lord of Andúnië can be 7 feet tall or 7 feet eleven inches tall: I don’t think it matters.
Elu Thingol can be taller yet: an inch taller, or 9 feet tall: I don’t think that matters, either. Poor
Robert Wadlow died because his leg brace caused an infection, but he failed to notice until it became septic (he was apparently
a very gentle, kind person); but
Tolkien is not writing history: he’s writing a story about
Elves,
his Elves, inspired by the
languages they spoke, and in the process creating a myth to go with them, a myth for English speakers. Besides, without rigorous measures, in the real world people can’t agree about whether a person was this tall or that tall; whether his eyes were brown or blue or green; whether his hair was black or brown or red; whether he did this first or that first, or often what he said last. (What
were Admiral Nelson’s actual last words? What did Edwin Stanton really say when Lincoln died? Who knows? Does it matter?)
Elendil the Tall was really tall: a head taller than most
Númenóreans, apparently, and they were a really tall bunch of folks.
Thingol was taller still: Elves who knew both Elendil and Thingol could confirm it. And one thing about Elves, at least until the end of
the Third Age: they were reliable witnesses with excellent memories, and none of them ever met anyone taller than Thingol, not even Elendil. But Elendil was still really tall, even for a
Númenórean.
Now how tall does that make
Aragorn? And if
Melian was attracted to Thingol in part because he was incredibly tall, was her great-great-great-granddaughter
Arwen attracted to Aragorn in part because he was unusually tall?
Olorgando: your suggestion was a bit of a stretch (ahem). But at any rate, the attraction certainly wasn't about his humility. He came off as someone who was a bit high on himself and ignored wise counsel.
A lot of fathers don’t see clearly where their daughters are concerned, especially if they don’t like her boyfriend! Thingol
was very wise indeed, but Melian was wiser and saw further; and she waited to contradict him, gently, when
Beren and
Lúthien were no longer able to overhear her. Likewise,
Celeborn the Wise lost his temper when the Company of
the Ring told him about the
Balrog in
Moria;
Galadriel gently remonstrated him, though unlike Thingol (likely Celeborn’s uncle, whom he had known personally: he might even have been witness to Melian’s remonstration of Thingol), he accepted his wife’s redirection.
