Huge in terms of height of course. Today, I thought I could battle with the Ebony guy for the first time, got my gear and traveled to Skyrim to search for him. Then I found him in Wihelm (spelling) and he was not what I expected...
He is literally much higher than my Nord or any high elves, so at that second I thought he was a Heartland High Elf and everyone assumes he an High Elf due to same skin(the present one) and not everyone seen a High Elf.

I was exicted as hell when we agreeded to fight on Last Vigil since I thought he was a Heartland High Elf.
Upon my arrival, I annouce the battle by weiding the Nordic Sword and attacked him. He was worthy to battle with and he's beyond my Skills to even have a chance of killing the warrior. I died too many times with the blade and began to show the Wraith of my Power! Summon two Dremoth Lords, my dragon and that dead dragon whom name I forgotten... to kept him distracted but still that was not enough. At long last I defeated him by jabbing my sword through his abomen while he was on the floor, crawling to the nearest salvation.
I was terribly desperate to see his face even I was just expecting a High Elf's face template or something but as I take the helmet off... It was a Redguard?!!!!
How can a Redguard be as huge as twice the nord size and how come he can gain passage into Sovngarde via Death when he's a Redguard?
Anyway, what was your Legendary battle with the Ebony Warrior like?
