For larger spaces, like dining rooms, I recommend either the Standard Medium Edge or The Standard Wide Edge. If puzzles are your main focus, go with the medium. For boardgames, D&D, or Warhammer, go with the wide. Both of these will comfortably fit between 6 and 8 and possible more if you want to squeeze them in. I also recommend going with the red oak board upgrade for tables in this space. This will look nice and will wear better over the years.
