Rugby stadium quiz: Guess the capacity of stadiums in rugby union and rugby league

Football stadia knowledge seems to be a fun subject amongst fans, but what about rugby stadiums?

It got us thinking...

So, calling all rugby followers of both union and league persuasion - how well do you know your rugby stadiums?

We really want to test you with this by estimating the capacity of the grounds listed across both codes, putting the options in order with the largest first.

How well do you know your Sandy Parks and your Headingleys? Good luck!
