Ring size for Cotto/Canelo?

[Baltimore]

Anyone know what size the ring is going to be tomorrow? I think most would agree a bigger ring is beneficial to Cotto, where as the smaller the better for Canelo.

Also, does anyone know if it is going to be a normal blue canvas or black like in Cotto's last fight?

I googled but couldn't find anything.

Standard ring size in Vegas is 20x20. I haven't seen anything changing this.
