In my experience, most standard single sleeping bags, are built so you can zipper them together to make a double. They are designed to zipper to an identical bag, so don't count on buying to different bags and have them work together.

Instead of buying a dedicated double bag, buy a matched pair that can be joined. Google sleeping bags that can be joined together or sleeping bags that can be zipped together
