This tip comes from a bride and it is something to think about when making your seating chart and the number of guests you plan to have at each table.
A standard round table (at most venues) is a 60 inch round table and can seat up to 10 guests. Just because you can do this doesn’t always mean you should. If you have lots of left hand guests (like bride Marina) consider only seating 8 people per table. Left hand guests could actually bump elbows with all those right hand guests if you seat too many guests at a table. So remember to leave a little elbow room.
