There are some massive men competing in the Six Nations, so with the help of Opta we have compiled a list of the biggest heavyweights competing this season

Who is the heaviest player in the Six Nations?

Ahead of the first Six Nations match of the year, with France taking on Wales, the hosts named a group of forwards that was dubbed “the heaviest pack in history”. Weighing in at a approximately 962kg (give or take) it was a whopper scrum.

Which got us wondering – who is the heaviest player, according to the official stats? So we asked our mates at Opta, who keep tabs on this kind of thing. They provided us with this table of heavyweights from the current squads below.

Team Player Weight
France Uini Atonio 145
England Harry Williams 132
Wales Tomas Francis 130
France Paul Willemse 127
Scotland Simon Berghan 126
Wales Leon Brown 126
England Billy Vunipola 126
France Mathieu Bastareaud 125
Wales Alun Wyn Jones 125
Ireland Devin Toner 124
Ireland Quinn Roux 122
Wales Jake Ball 122
Ireland John Ryan 121
Italy David Sisi 120
Scotland WP Nel 120
Scotland Grant Gilchrist 120
Scotland Murray McCallum 120
Wales Adam Beard 120
Wales Dillon Lewis 120


It is no surprise that the gargantuan La Rochelle prop Uini Atonio is at the top of the list.  Next down is England’s Harry Williams – with Exeter team-mate Tomas Francis just a few kilograms behind.

It is a who’s who of forwards talent, with a little Mathieu Bastareaud thrown in. You may be surprised not to see Mako Vunipola or Tadhg Furlong in there, but according to Opta they have shaved off a few clicks in recent times (on Saturday, against England, Furlong was listed as 119kg in the match programme).

There are a few fans’ favourites on that list of hefty players, for sure.

But what about the average squad weight?

Team Weight
England Average 104.5
Ireland Average 103.3
Wales Average 102.5
France Average 101.8
Scotland Average 100.6
Italy Average 100.2


Remember we’ve used the words ‘average’ and ‘squad’ here, so every member of the wider training group is accounted for in this number. England come out on top, Italy are at the bottom. Who knows, maybe this is what the final Six Nations table will look like too…

Surprised that France don’t top this list? Turns out they have more shapes and sizes than you thought. Looks like England have just that little bit more heft.

Thanks to Opta for the statistics.
