Every couple agonizes over the seating chart. Here's a way to find the right spot for every guest. First, divide your guest list into categories -- such as wedding party, family, our friends, family friends -- and assign a different-color low-tack adhesive note to each. Then write out everyone's names on the appropriately colored strips. You can arrange and rearrange them around simple photocopied outlines of your tables. The note colors show whether you have a good mix at each table. When it's time to set out the place cards, tape the notes in place, then hand the completed sheets to the setter.

It's so important to have a seating chart because people expect one. Plus, it's only for dinner. If people want to hang out with someone else not seated at their table, then when dinner's over they can hang during the dancing and other activities!
Just so we don't have to have more tables then we actually need I did a seating chart.
Its not nessacary but I am for my small wedding just to make sure everyone fills up the space properly. Like I don't want a small group to take the big table that is better suited for a larger family.
do you have to have a seating chart?!?!?
