Yes, Wii fit balance board has a weight limit.
It seems that it has two versions.
As for the Japanese packaging, the weight max of the Wii fit Balance Board is 136 kgs, it is equal to 300 lbs. And the weight limit of the Wii fit balance board that sells in US and Euro is 150 kgs ( 23 stones 8 pounds ), it is equal to 330 pounds.
So, sometimes you may get the answer 300 pounds, sometimes, it is 330 lbs, they both are right.
It states somewhere on the Wii fit balance board, you can find it.
