Enter your table count, seats per table, and catering cost per guest — then assign every guest to a seat and get meal counts by table, capacity status, and a clean caterer-ready summary.
Sixteen tables. A hundred and forty guests. Fourteen with dietary restrictions. A caterer demanding a per-table meal count 48 hours before your event. Doing all of that in a shared spreadsheet means manual tallies, formatting errors, and redoing the math every time someone cancels or a plus-one confirms. This planner handles the assignment logic and outputs the counts automatically.
The tool shows how many seats are assigned, how many guests are still unassigned, total capacity across all tables, and the catering cost estimate based on your cost per guest. The Meals Per Table view gives your caterer exactly what they need for plating. When someone cancels and you move three guests around, the counts update instantly.
Setting up your table configuration before you assign anyone
Start by entering Number of Tables and Seats Per Table. The tool calculates total capacity immediately — if you have 16 tables at 8 seats, that is 128 seats for your confirmed guest count. Enter Catering Cost Per Guest to see the estimated catering budget as you assign guests. If your caterer charges $95 per head, 128 confirmed guests puts the catering number at $12,160 before gratuity and service fee.
Most venues work with standard round tables of 8 or 10. If you have a mix — some rounds of 8 and a head table of 12 — you can configure tables individually. Getting the capacity right before you start assigning prevents the frustration of realizing mid-assignment that you are three seats short for the B-list additions.
Tracking meal choices so your caterer can plate by table
Caterers plate meals by table, not by a master list. Telling your caterer '47 chicken, 38 beef, 15 vegetarian' is less useful than 'Table 4: 7 chicken, 1 vegetarian; Table 5: 6 beef, 2 chicken.' The Meals Per Table view outputs exactly that — counts of each meal choice per table, ready to hand to the banquet captain.
When guests are added through the Add Guest form, you record their meal preference at the same time. The meal counts stay current as you move guests between tables. If the last-minute table reshuffle moves the vegetarians from Table 3 to Table 7, the counts update without you manually re-tallying. This is the detail that gets overlooked when seating charts live in a shared Google Sheet.
The unassigned guest problem: catching it before the day of
The Unassigned count in the summary panel is your safety check. If you have 142 confirmed guests and the tool shows 14 unassigned, those are people who confirmed attendance but do not have a seat yet. The Table Overview panel shows capacity status per table — which tables are full, which have open seats, and where there is room for the unassigned group.
Most seating chart disasters happen when the organizer thinks everyone is seated but a family group fell through the cracks because they confirmed late and got added to a list without a table assignment. Keeping the Unassigned counter at zero before you send the caterer your final count prevents the last-minute scramble for extra chairs.
Managing last-minute changes without losing your mind
Guest cancellations and additions happen until the day before the event. When someone cancels, removing them from their table immediately updates the capacity status and meal counts. When a plus-one is confirmed 10 days out, you add them and the tool shows you which tables have open seats. Doing this in a static spreadsheet means hunting for the row, updating multiple columns, and hoping the formula references did not break.
The Table Fill Rate chart gives you a visual capacity check — tables running at 50% capacity might be candidates for consolidation if the final guest count drops. Presenting a room that feels full and arranged well matters for the guest experience; the Fill Rate view helps you decide whether to pull a half-empty table or leave it for guests who want more space.
Using the catering estimate as a budget checkpoint
Catering is typically the single largest line item in an event budget, often running 35–50% of total spend. Entering your cost per guest into the tool gives you a live catering estimate that tracks with your final confirmed count. If your venue requires a guaranteed headcount 72 hours before the event and you are at 138 confirmed guests, you know the catering commitment is $13,110 at $95 per head before you finalize the guarantee.
The estimate does not include service charges or gratuity, which typically add 20–25% to the base catering cost. Build that into your mental budget when reviewing the output. If the confirmed count comes in significantly above your original catering budget, knowing it two weeks out gives you time to negotiate a per-head reduction or adjust the menu tier rather than absorbing the overage at the event. Start free, lock in your seating plan, and hand your caterer accurate counts — no last-minute spreadsheet scramble required.
How to use it
- Enter Number of Tables and Seats Per Table to establish total capacity — the tool shows you immediately whether your room layout fits your guest count.
- Enter Catering Cost Per Guest to see a live catering estimate that updates as confirmed guests are assigned.
- Use Add Guest to add each confirmed attendee with their name, meal choice, and table assignment.
- Check the Unassigned count in the summary panel — it should reach zero before you send the caterer your final counts.
- Use the Meals Per Table view to export per-table meal counts for your catering team's plating plan.
Who it's for
- Wedding planner managing 160-guest reception — Sixteen tables of 10 at $110/head puts catering at $17,600. Planner uses the Meals Per Table export to hand the banquet captain a table-by-table meal breakdown, cutting the usual pre-event coordination call from 45 minutes to 5.
- Corporate event coordinator for a 90-person gala — Mix of round tables of 8 and a head table of 12. Tool surfaces 4 unassigned guests on final check — all from one department that confirmed late. Coordinator adds them to Table 9 which shows 2 open seats and adjusts by adding a fifth guest elsewhere, keeping the caterer's guaranteed count accurate.
- DIY couple doing their own wedding seating — Saves several hours versus the shared-spreadsheet approach. Husband and wife each log in from different devices to move guests, and the live unassigned count prevents double-booking a seat. Meal counts export cleanly for the caterer without a manual tally.
- Venue manager tracking multiple events per weekend — Saves each event's seating plan separately. Can pull up Saturday's 120-person dinner and Sunday's 75-person brunch independently, each with their own capacity and meal count configuration, without the two plans interfering with each other.
Key terms
- Table fill rate
- The percentage of seats at each table that are assigned to confirmed guests. A table with 8 seats and 6 assigned guests has a 75% fill rate. Low fill rates across multiple tables may indicate opportunity to consolidate and improve room atmosphere.
- Guaranteed headcount
- The final confirmed guest count submitted to the venue or caterer before the event — typically due 48–72 hours in advance. The venue will charge for at least this number regardless of actual attendance.
- Per-table meal count
- The number of each meal selection at a specific table, used by caterers to plate and serve meals by table rather than from a single master list. Providing this breakdown prevents service delays during plated dinner courses.
- Catering cost per guest
- The base per-head charge from your caterer for food and non-alcoholic beverages. This figure typically excludes service charges, gratuity, alcoholic beverages, and rental fees.
Frequently asked questions
How do I handle tables with different seat counts?
Configure each table individually rather than using a uniform seats-per-table number. The tool lets you set capacity per table so a head table of 12 and rounds of 8 are both reflected accurately in the total capacity and fill-rate calculations.
What meal choices can I track?
You can enter any meal preference when adding a guest — chicken, beef, fish, vegetarian, vegan, or any custom label your caterer uses. The Meals Per Table output counts each preference by table regardless of what the labels are.
What happens if I move a guest to a full table?
The tool flags the table as over capacity and the Table Overview shows a warning for that table. You will need to move another guest out before the assignment is valid. The Capacity Status column makes it clear which tables have room and which are full.
Is the catering estimate the final number I give the venue?
It is the base cost before service charges, gratuity, and tax. Most catering contracts add 20–25% in service charges and applicable sales tax. Use the tool's estimate as the base figure and apply your venue's specific add-on rates for a full budget estimate.
Can I use this for non-wedding events like corporate dinners or fundraisers?
Yes — the tool works for any plated seated event. The same table configuration, guest assignment, and meal-count logic applies whether it is a 50-person fundraiser dinner or a 200-person corporate awards ceremony. The catering cost per guest field can be adjusted to match any event's per-head rate.
