Rehearsal Dinner Seating Chart: Pick a Shape, Assign the Table
A rehearsal dinner seating chart, worked as a 20-guest test across round and trestle tables, so you pick the shape with no empty chair before naming a single seat.

The wedding table plan is already sorted, and now someone is asking where twenty people sit at Thursday night's rehearsal dinner. A rehearsal dinner seating chart runs on the same logic as the reception one, just with a shorter guest list and one decision that comes first: pick a table shape, because the shape decides how many chairs exist before a single name goes anywhere.
How many chairs each table shape actually gives you
Three shapes cover almost every rehearsal dinner room: a round table, a short trestle, and a long trestle run. Easy Weddings suggests eight guests around a standard round table as a general rule of thumb, though tables in use range from two seats to twenty.1 One Australian event hire company is more specific about its own stock: a 1.8 metre round table seats 8 to 10, and its 2.4 metre trestle seats 8 to 10 as well, four along each side and one at each end.23 The same hire company's 1.8 metre trestle seats 6 to 8, three a side and one at each end.3
The 20-guest test: which setup leaves an empty chair
Run one rehearsal dinner guest list of 20 against three real setups, using the seat count each hire company publishes for its own tables rather than a formula.
| Setup | Tables | Seats available | Empty chairs |
|---|---|---|---|
| Round tables, rule of thumb (8 each) | 3 | 24 | 4 |
| Round tables, 1.8m at top capacity (10 each) | 2 | 20 | 0 |
| Trestle 2.4m at top capacity (10 each) | 2 | 20 | 0 |
Easy Weddings' looser rule of thumb needs three round tables and leaves four chairs empty - the table nobody wants to be seated at.1 Two round tables at the 1.8 metre size's own stated top capacity, or two 2.4 metre trestles end to end, both land on twenty with nothing spare.23 Fewer tables, no empty chair, same guest list.
How much seating chart you actually need
Not every rehearsal dinner earns a full chart. Rank the options by effort, lowest first:
- No assigned seats. Guests choose. Works under about a dozen people, or
at one long table where everyone can see everyone else down its length.
- Table groupings, no name cards. Put people at a table and let them
pick a chair within it. Works cleanly for the two-table setups above, where each table is already a natural group.
- A full seating chart, named cards. Worth the effort once the guest
list crosses about twenty, or a family split makes "sit anywhere" a bad idea on its own.
Build it in the seat planner you already have open
PlannedBy's seat planner ships a rectangle table tool built for exactly the long-trestle setup above: drag the table longer and it adds seats down both long edges as it grows, the way an actual long table works rather than a fixed shape stretched to fit. Use the same tool and the same guest list built for the reception - filter it down to who is actually coming Thursday night, then place them at whichever shape the test above pointed to.
Why bother charting a rehearsal dinner at all
83% of Australian couples run allocated seating at the wedding reception itself, against 9% who let guests choose.4 The guest list is already the second most-named planning stressor nationally, at 15%.5 A rehearsal dinner is smaller and lower-stakes than the reception, but it asks the same question of fewer names: who sits well together, worked out before the night starts rather than during it.
FAQ
Do I need a seating chart for a rehearsal dinner? Only past a certain size. Under about a dozen guests, or with one long table everyone can see down, assigned seats add effort without adding much. Past twenty, the 20-guest test above shows why a plan beats a shrug.
How many people fit at a rehearsal dinner table? Depends on the shape. A standard round seats about eight by rule of thumb, or 8 to 10 at a 1.8 metre round's stated top capacity. A 2.4 metre trestle also seats 8 to 10, and a 1.8 metre trestle seats 6 to 8.123
Round tables or one long table for a rehearsal dinner? For 20 guests, two round tables at their top stated capacity or two 2.4 metre trestles end to end both seat everyone with nothing spare. Three round tables at the looser rule of thumb leaves four chairs empty.23
Can I reuse my wedding seating chart tool for the rehearsal dinner? Yes - it is the same guest list and the same tables, just fewer names. Filter the reception list down to Thursday night's attendees and place them in the same seat planner.
What if the venue only has long tables? Use the rectangle table tool and the trestle numbers above rather than forcing a round-table plan onto a room that does not have any.3
The shortest path from here
Match the guest count to the table math above, pick whichever shape lands on zero empty chairs, and place names in the same seat planner already open for the reception.
