A king size quilt cover would be better than a queen size quilt cover if you have a king size bed. The queen size quilt cover would be too small. If you have a queen size bed, a king size quilt cover may still be better as it will hang over the sides a bit and, therefore, be less likely to come off during the night.
The size of a Standard King size duvet cover in North American is 102" x 86" or 259 x 218 cm. This is also the same size duvet cover for a California King.
King.

If you happen to have a California king (aka cal king), the king sized comforters will be too short. Otherwise, watch the dimensions and the picture on the different manufacturer's packages. Some are just big enough to cover the top of the bed and not hang down to the floor.
Big enough to fit a king size bead. What the hell kind of question is this?
It really depends on the size of your bed. If you have a full or queen size bed a king size or Cal King duvet cover might be able to cover the box spring. I recommend getting a bed skirt which will fully cover the the box spring.
A duvet cover in king size can be found in most furniture shops. A good low cost start would be to check out chains like Target or IKEA for a reasonably priced cover
There are a number of retailers one can purchase a king size duvet cover from both online and in store. One can purchase them from 'Amazon', 'Macy's', 'Walmart' and 'John Lewis'.
Yes, but it will be a little big.
It depends how big you are
