The world of rugby is full of some of the biggest men in sports. And the last rugby world cup proved that these men have never been bigger or stronger. Some of them look like they could be gladiators from Roman history.

And a lot of them will completely dwarf American football players. So, we decided to look at Rugby Union players from around the world and see what kind of sizes they have achieved in recent rugby history.

To do this, we focused on their official player profiles, and we ranked them based on their weight. As you’ll see, these test rugby players are massive.

Quick Summary

  • Some of the biggest rugby players ever include Sean O'Brien, Sonny Bill Williams, Manu Tuilagi, Jamie Roberts, Sergio Parisse, Joshua Tuisova, David Pocock, and Tendai Mtawarira.
  • To achieve a huge rugby body, you must engage in strength training, High-intensity interval workouts, and eat healthily.
  • Supplements such as mass gainers, and protein powders can also be used for muscle building.

The World’s Biggest International Rugby Players

1 - Opeti Fonua

  • Height: 6’6”
  • Weight: 308 lbs

While Opeti’s weight has fluctuated a lot, it peaked a few years ago at over 300 pounds.

That’s an immense size, and if you look up some videos of him playing for the English team Leicester Tigers or Tonga during the world cup tournament, you’ll get an idea of how he can make other rugby players just bounce off him.

2 - Taniela Tupou

  • Height: 5’10”
  • Weight: 298 lbs

There must be something in the Tongan genes and diet because while Taniela Tupou plays on the international team for Australia and on a weight-to-height ratio, he would beat Opeti.

From the moment he made his international debut at a world cup qualifier, the rugby world knew it had a new star-tight head prop.

3 - Alesana Tuilagi

  • Weight: 273 lbs

Alesana is one of the infamous Tuilagi brothers from Samoa. There are five of them in total, and they all play rugby. And you most certainly don’t want to get on their wrong side.

For a man that plays on the wing, he has a surprising amount of speed despite his sheer size.

4 - Eben Etzebeth

  • Height: 6’8”
  • Weight: 269 lbs

Eben is a South African Rugby Union player, and he’s one of the tallest rugby players on our list at 6’8” [1]. With that height and weight, he is known for punishingly big hits.

He’s also one of the strongest on the South African squad as he can reportedly bench press 385 lbs.

5 - Andrew Porter

  • Height: 6’0”
  • Weight: 269 lbs

Andrew Porter is an Irish Rugby Union player who plays for his home team Leinster.

He plays both in a tight and loose forward position, and according to some sources, he can squat over 770 pounds. That makes him an immense asset for the scrum.

6 - Joe Marler

  • Height: 6’0”
  • Weight: 260 lbs

Joe Marler is probably England’s biggest Rugby Union player, or at least we weren't able to find any bigger rugby players in England.

He’s been a fighting force at the World Cup and is arguably one of the best loosehead props to have played the game in recent years.

And with over 220 appearances for his home team Harlequins, he’s set to become one of the team’s longest-serving players.

7 - James Haskell

  • Height: 6’4”
  • Weight: 260 lbs

Here’s a Rugby Union player who literally looks like a gladiator.

There’s not an ounce of excess fat, and this big man from England is one of the strongest flankers we could find.

Apparently, he can bench press over 400 lbs, which explains why fans look forward to him simply pushing other players out of the way.

8 - Tendai Mtawarira

  • Height: 6’2”
  • Weight: 260 lbs

If you put Tendai into any kind of physical sport, he wouldn’t stop surprising you with athletic talent and sheer force.

The rugby player from South Africa is also called “The Beast” for being such a powerhouse on the front row of his club (The Sharks) and national team.

Apparently, he can squat over 540 lbs, which makes him possibly the strongest rugby player in his country.

9 - David Pocock

  • Height: 6’0”
  • Weight: 254 lbs

Let’s get back to Australia and take a look at David Pocock, weighing in at over 250 lbs. He is a huge flanker and plays for his home team, The Brumbies, in Australia.

And ever since his early days in professional rugby as a youngster, he has had a great scoring record throughout his career.

10 - Josua Tuisova

  • Weight: 249 lbs

Josua Tuisova is a massive rugby player from Fiji and a surprisingly big rugby player to play on the wing.

But if you watch him carefully in a rugby match, you’ll see that he carries his weight and the ball with some incredible speed.

Someone has timed him running 90 meters in 10 seconds, which isn't far off Olympic sprint speeds.

11 - Sergio Parisse

  • Height: 6’5”
  • Weight: 249 lbs

Born in Italy and playing for Toulon, Sergio is also the captain of the Italian team. Weighing in at just under 250 pounds, he’s the biggest rugby player in Italy.

He was rumored to be heading to play the game in France, but so far, he has denied such a move will happen.

12 - Jamie Roberts

  • Height: 6’4”
  • Weight: 243 lbs

Jamie is the biggest rugby player from Wales, and at 6’4”, he’s also among the taller ones. His club is The Dragons, and he has won 94 caps for the Welsh national squad as well.

He’s played the game professionally since 2007, but his age doesn't seem to be making him slow down or make him less imposing.

13 - Manu Tuilagi

  • Height: 6’1”
  • Weight: 242 lbs

Here is the second of the Tuilagi brothers from Samoa, and he’s arguably the strongest one in the family. Being able to bench press 415 pounds, he could make it to the list of strongest players in the sport as well.

He recently left the Leicester Tigers to join the Sale Sharks, where he might see out the remainder of a massive career.

14 - Sonny Bill Williams

  • Height: 6’3”
  • Weight: 238

Sonny Bill is arguably the greatest player from New Zealand since Jonah Lomu.

While it’s unfair to compare Sonny to Jona Lomu, considering that the game has changed a lot, he certainly enjoys the same level of worship and respect [2].

And because he was a professional boxer in New Zealand, it’s another reason to be careful of his barging runs.

“For me to get through the toughest periods in my life, I had to look within to find the energy to do it. I don't give up. Never have. Never will.”

- Jonah Lomu

15 - Sean O’Brien

  • Height: 6’2”
  • Weight: 238 lbs

And for our fans from Ireland, we’ve added Sean O’Brien to our list as well. At the age of just 24 years, he’s also one of the younger rugby players with such an imposing physique. You can hardly believe this man's age since he has that lovable rugged look while sporting a winning smile.

He plays for London Irish in the English Premier League and has also made it on the Irish and British Lions squad.

Do You Think We’ve Missed Someone On This List?

We could probably have gone on to extend this list to 50 or more players, but we thought it was best to keep it to the absolute biggest ones.

I’m sure there will also be new younger players coming up the ranks to make this list.

To be honest, though, I somehow think that Opeti Fonua and Taniela Tupou will maintain those top spots for some time to come.

At right around 300 pounds, it’s difficult to believe they will be beaten any time soon.
