How many tables of eight fit a normal wedding room?
Count movement, not just table tops: a round of eight needs room for chairs and a service gap, and dancing needs open floor. Ask the venue for their maximum seated count, then build one or two tables under it — that margin is your dance floor and your band.
Round tables or long tables?
Rounds seat more people comfortably and keep conversation within a circle — eight to a side works socially. Long tables suit grand head tables and small rooms where the family wants to see each other across the length. Many couples run one long table at the front and rounds behind.
Do we need a seating chart at all?
Yes, if you want the conversation to land. Unassigned seating produces the lonely seats that always appear by the ninth minute; names on a page get guests to their people and the evening started comfortably.
When do we finalise the seating plan?
After the last reply, not before. Seating is downstream of the list: you cannot place people who haven't confirmed or fill in for households that declined. Finalise the plan a week or two before, then publish it to the page so guests can look the day they arrive.
How do we handle a guest who doesn't find their name?
Give one person at the door — a trusted friend with nothing else to do — the master list, and let them check the seating on their phone. Guests who can't see their name on the page simply get told, in seconds, which of the friendly options is theirs.
