I have a Bailey 17" and a majestic frame. It is the largest frame offered by the Grace company and that is why I got it. I like my quilts to drape over my bed, so really for a queen bed, I need a king size quilt. To be honest, I have not set up my contraption yet. It all arrived this week and I will be putting it together tomorrow. The fame is big enough for a king, and I am certain that 17" of space on my bailey will be adequate. After all, the majestic does not take machines over 18", so I am pretty sure that doing a king size will not be an issue.
