Traditionally, he was left-handed. He held the shield with his right hand and and his sword with his left hand. But in Twilight Princess it was mirrored, so Link was right-handed instead, so that when we balançoire, swing with our right hands he swings with his as well (because otherwise it would be spazzy.) It will probably be the same way with all games following Twilight Princess.
Link is ambidextrous. He can use both his right and left hands, and this has been confirmed par nintendo. The only reason he is consistently depicted as using the sword in his left hand is because he supposedly prefers it over his right, but he can use both, which is also why the SS Link was right handed(aside from the majority of the world's population being right handed).
In the ORIGINAL Twilight Princess for Gamecube, he's left handed, as he is in the other games. When they remade it for Wii, they changed it because the majority of people are right handed. They just wanted Link to match the player to make it less confusing. :)
He is officially left handed, but Nintendo made him right handed in Twilight Princess and in the new Skyward Sword because the sword is controlled par using hand movements, and the majority of people are right handed, so Nintendo adapted him to these conditions. In any other game he is left handed.
He is left handed although there are re encarnations of link so in some of the games he will look like if he's right handed, but officially he is left handed (here's one where he has sword on left hand, it's the razor sword and hero's shield which is acquired in majora's mask)
Left handed, Right handed and ambidextrous because most are re-incarnations to Skyward Sword's Link. So most people can USE their right hand easily and MOST people who are ambidextrous use their right hand plus than their left hand like me and my sister. 72% of the world are right hand 12% are left hand and 16% are ambidextrous roughly I may not be correct for the percentages but I am close.
Link is left handed. Nintendo and maybe if toi have the book "Hyrule Historia" have a dit that Link is left handed. In every game toi can see that Link is left handed but in the games "Twilight Princess" and "Skyward Sword" Link is right handed BECAUSE those games are made for the Wii console and the most of the people are right handed so the creators were forced to make Link right handed for the gamers to be comfortable playing the game.
If I remember correctly, all the Zelda games I've played portray him as being left-handed apart from Skyward Sword and the Wii version of Twilight Princess. This is because motion controls were introduced, so they flipped the original TP game and made Link left-handed in Skyward Sword in order to allow the player to feel better coordinated and plus like they're in the actual game as Link (since most people are right-handed). Also, the Zelda games don't all feature the same Link; surely it would be a tad unrealistic if they were ALL left-handed.
The Legend of Zelda series has shown Link as right handed and left handed. I don't think there's really an asnwer because it doesn't say. So I think we can just assume that Link is both, I don't remember what that's called, but I think he might be both.
Most sword users use their right hand to wield their sword, as they (usually) use their left to cover their vital organs such as their heart. However, it's been confirmed that Link is ambidextrous, as well as have many incarnations, allowing multiple liens with differing prominent hands.
It just depends the game. Especially since in each game, it's not the same Link. (Except Hyrule Warriors, but FUCK YOU) In some games he's right-handed, and in others, he's a lefty. But he tends to be right-handed in most of the games.
