How planners seat 300 to 400 wedding guests: tables and room sizes from our floor plan tool, table numbering, seating in blocks, service and finding seats.
For 300 guests at 60-inch rounds of eight, with a 10-seat head table, plan 37 guest tables; at 72-inch rounds of ten, 29. In our floor plan tool, a full reception for 300 (head table, dance floor, DJ and bar) fits a 120 by 60 foot room, about 24 square feet per guest. At this size, fix the room and table size first, seat families and friend groups as blocks, number tables so guests can find them, and give guests more than one way to find their seat.
A 120-guest wedding can be seated from memory. A 300-guest wedding cannot. Three things change:
These are what the floor plan tool draws with its defaults: a 10-seat head table, a dance floor sized for a third of the guests, a DJ and a bar, no buffet, 5 feet between table edges. "Smallest room that fits" is the smallest of the rooms we tried (100 by 60, 120 by 60, 120 by 70 and 120 by 80 feet) that holds the whole layout at 60-inch rounds.
| Guests | 60-inch rounds of 8 | 72-inch rounds of 10 | Dance floor | Smallest room that fits (60-inch) |
|---|---|---|---|---|
| 300 | 37 tables | 29 tables | 21 x 21 ft | 120 x 60 ft (36.6 x 18.3 m) |
| 350 | 43 tables | 34 tables | 24 x 24 ft | 120 x 60 ft (36.6 x 18.3 m) |
| 400 | 49 tables | 39 tables | 24 x 24 ft | 120 x 70 ft (36.6 x 21.3 m) |
Two things stand out. A 100 by 60 foot room, which looks big, fits 274 guests at 60-inch rounds in the tool, and 290 at 72-inch rounds, so it falls just short of 300 either way. And at 400 guests, the 120 by 60 foot room fits 354 at 60-inch rounds and 350 at 72-inch rounds, so a change of table size does not rescue it. These are one tool's layouts on a square grid, not a survey of real venues; a room's real shape, pillars and doors move the numbers in both directions.
For a sweetheart table or other table sizes, the couples' guide on tables for 300 guests works the counts another way.
At this size, the venue's legal capacity is often the real limit, not the floor plan. A fire code occupant load is set by floor area and by exits, and the venue's posted number for a seated dinner is the one that counts. The venue capacity guide explains the rules in the US, UK, Canada and Australia. Ask the venue for its capacity for your exact layout before you show the couple a plan.
With 40 tables, a number on a card is only useful if the number is easy to find in the room. Common planner practice:
Work from the outside in, as for any wedding, but by group rather than by name:
The seating chart workflow guide covers the same order in detail, and the divorced parents guide covers the tables that need the most care.
The caterer feels the size most. Give them:
Escort cards for 300 guests mean 300 cards laid out alphabetically, usually during cocktail hour. A single printed board means a queue. A QR code is the alternative: guests scan, type their name and see their table on their own phone, so the crowd spreads out. Put up more than one QR sign, keep a short printed alphabetical list beside each, and have someone near the entrance for the first 20 minutes. The escort cards vs QR guide compares the options.
Our case study of a 716-guest wedding seated with one QR code shows how that worked for one couple.
Forever Farrah has seated large weddings in one chart: the couple in our case study seated all 716 of their guests on the Forever plan, which has no limit on how many guests can be seated. In the planner dashboard, each client wedding's guest list and seating chart live in one place you and the couple both see. Import the list from a spreadsheet, lay out the room in the seating studio, let Matchmaker (automatic seating) place every guest, then drag anyone who needs moving. A free client wedding seats up to 50 guests; a wedding of 300 or more needs the couple's Forever plan, and each wedding can be upgraded on its own, by you or by the couple. At the reception, guests scan one QR code and find their table on their phone. Your first 2 client weddings are free.
With a 10-seat head table, 37 tables at 60-inch rounds of eight, or 29 at 72-inch rounds of ten, in our floor plan tool.
In our floor plan tool, a full reception for 300 at 60-inch rounds, with a head table, dance floor, DJ and bar, fits a 120 by 60 foot room (about 37 by 18 meters). The venue's posted capacity is the legal limit.
With escort cards laid out alphabetically, a printed seating display, or a QR code guests scan on their phone. At this size, more than one QR sign with a printed list beside each spreads the crowd.
