Wedding table cards are required if your wedding or event guests will have assigned seating. Guests will look for their seats based on the table number to which they are assigned. A table card makes finding it easy for guests. First, what is a table card? In its very basic form, a table card is a type of signage used to identify a table for your guests. If they are numerical, traditionally, lower numbers are reserved for the wedding party and immediate family. In addition, the couple may be seated at their own table, usually designated as the sweetheart or king’s table.
