The guide below is the perfect tool to help you get started in planning your space. A good rule of thumb to follow is to allow 24-30" between each guest at a table for a comfortable fit.  You can go tighter but keep in mind your chair width and table top setup - the larger the chair or larger the setting, the more space needed between each guest.
