As of 13 August 2026, AI can design your wedding seating plan.

What to actually do

1. Do it yourself

   The route this page recommends

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a spreadsheet and make a complete guest list with one person per row, including partners, household groups, accessibility needs and any people who must or must not sit together.
   2. Write down the number, shape and capacity of every table, plus the couple's preferred table arrangement and any venue restrictions.
   3. Add a separate list of hard constraints and softer preferences, keeping facts such as family relationships separate from guesses about who will get on.
   4. Paste the guest list, table details and constraints into a chatbot using the prompt, then ask it to produce the table-by-table plan and spreadsheet-ready version.
   5. Compare the output against the spreadsheet by checking that every guest appears exactly once, every table is within capacity and every hard constraint is marked correctly.
   6. Ask the chatbot to revise only the specific errors or conflicts you found, then repeat the name and capacity checks on the revised plan.
   7. Send the checked table allocations to the venue or wedding coordinator for a practical layout check before printing place cards or a table plan.

   Prompt

   Design a wedding seating plan from the information below. Do not invent guests, relationships, constraints or venue details. Treat hard constraints as mandatory, treat preferences as suggestions, and flag any conflict instead of silently breaking a hard constraint.
   
   Wedding details:
   - Number and shape of tables: [for example, 10 round tables]
   - Seats available at each table: [details]
   - Couple's preferred table or top-table arrangement: [details]
   - Venue or layout restrictions: [details]
   
   Guest list, with one person per line:
   [Name | group or relationship | partner or household | children or age group if relevant | accessibility or dietary seating needs]
   
   Relationships and constraints:
   - People who must sit together: [details]
   - People who should not sit together: [details]
   - People who would get on well: [details]
   - Guests who need particular accessibility, sightline or proximity arrangements: [details]
   - Any other preferences: [details]
   
   Produce:
   1. A table-by-table list of every guest.
   2. A count of guests and seats at each table.
   3. A list of every hard constraint and whether the plan satisfies it.
   4. Any unresolved conflicts, missing information or assumptions.
   5. A short, neutral reason for each table's mix.
   6. A plain text version that can be copied into a spreadsheet.
   
   Check that every guest appears exactly once, no table exceeds its capacity, partners and required groups are handled as specified, and no unprovided fact is treated as true. Do not claim that the arrangement will prevent awkwardness or guarantee that guests will enjoy it.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

2. Use a tool built for this

   Second choice

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
