As far as my research indicates there is no bed bigger than a standard king. A California king is longer but narrower.

It's rare, but I know at least one person who has a San Francisco King (7x7, just like the city).

That's really just a custom with a clever name. Try searching for "san francisco king" sized sheets anywhere.

I know :) But it seemed like a fun place to bring it up.

I sleep in a super king. 6'x6'6". It's a standard size in the UK.

The European King is 2.0 meters wide by 2.0 meters long.

Do the math.

We had a Euro King until we recently had to replace it. Buying sheets in Europe was no problem.

As do I, hence my joke comment, which by the downvotes, didn't go down so well, bah.
