Online Wedding Seating Plan: The Easy Way to Do It (Without Sticky Notes or Spreadsheets)

To make your seating chart easily, work online and in the right order: first the confirmed guest list, then the tables (shape, size, number), then the seating assignments, and finally the venue check and export for the caterer. An online seating chart tool like Mariable's does the thankless work for you: it imports your RSVP responses, locks full tables, calculates the space you need, and generates a print-ready PDF. The seating chart tool is included in the free account; PDF export is part of Mariable Couple (€29, one-time payment).

You've probably been told that the seating chart is the most painful part of wedding planning. It's not the seating itself that's painful: it's redoing it ten times because a guest drops out, a table of 10 doesn't fit, or the caterer is waiting for the table-by-table list of vegetarian meals.

Here is the 6-step method, the numbers you need to know (table sizes, room surface area), and what the Mariable tool actually does at each step.

Why the seating chart quickly becomes a headache

You might think it's as simple as distributing 100 people across 10 tables. On paper, that's true. In reality, your seating chart depends on three things that keep shifting until the very last minute:

• the guest list, which changes with every response and cancellation;
• the venue, with its layout, dance floor, buffet, and caterer access;
• the caterer's requirements: guest counts, kids' meals, dietary restrictions, and allergies.

With sticky notes or a spreadsheet, every change forces you to double-check everything manually. That's where you lose entire evenings.

Mariable's take

The seating chart isn't an exercise in family diplomacy where you have to please everyone. It is first and foremost a logistics problem, combined with personal choices. Save your energy for the decisions (who sits next to whom), and let a tool handle the logistics (the counts, seats, square footage, and exports). No software knows that your uncle and cousin aren't on speaking terms. On the other hand, it counts much faster than you do.

Step 1: Start with the confirmed guest list (not your initial list)

The seating chart is built with guests who responded yes, not with your initial guest list. Starting before the RSVP deadline is a surefire way to redo everything.

The right time: right after the RSVP deadline, which is typically 4 to 6 weeks before the wedding. You'll then have time to seat everyone and send the final figures to the caterer.

In Mariable: 4 ways to add your guests

You don't need to retype anything. The seating chart tool offers four entry points:

1. Import from your RSVPs: if your guests responded via the Mariable RSVP form, the tool only imports "yes" responses, along with plus-ones (displayed as "+1 Firstname L."), children, and stated dietary restrictions.
2. Import your guest list: from Mariable's guest management. Confirmed guests are already checked.
3. Import a spreadsheet: a CSV file exported from Excel or Google Sheets. Only the "Name" column is required; you can add "Type" (adult, child, or VIP), "Restrictions", and "Notes".
4. Add a guest manually: name, meal choice, and allergies.

All imported guests appear in an "Unseated guests" column, complete with a name search. Icons highlight children, VIPs, and guests with dietary restrictions.

Step 2: Choose the shape and size of your tables

This is the step most guides gloss over, yet it determines whether your room feels comfortable or cramped.

Which table shape should you choose?

• Round tables: the classic choice. Everyone can see and talk to one another, making them ideal for mingling guests who don't know each other.
• Rectangular or banquet tables: more convivial and space-efficient, perfect for a family dinner or a barn wedding. They take up less room per guest.
• Oval tables: a compromise between the two, elegant for a head table.
• Serpentine (S-shaped) tables: to break away from the "cafeteria" feel of a long row.
• High-top cocktail tables: for cocktail hour or a standing reception.

What table size for how many people?

Here are the standard dimensions used by caterers and rental companies, which the Mariable tool displays whenever you create a table:

Indicative dimensions: always check your venue or rental company's catalog, as models vary.

Our take: round tables for 8 to 10 people. Beyond 10, people only talk to the two people next to them. Below 6, you multiply the number of tables and centerpieces.

How many tables for 100 guests?

Divide the number of guests by the table size, then add the head table. For 100 guests using round tables of 10, plan for 10 tables, or 9 tables plus a head table. With tables of 8, you'll need 13.

In Mariable

You create each table with a name ("Head Table", "Saint-Malo", "Table 4"), a number, a capacity of 2 to 30 people, a shape, and a color. The tool instantly displays the table's standard footprint.

Step 3: Make sure everything fits in your room

This is the step nobody takes, yet it is the most useful. A seating chart can look perfect on paper and be impossible to set up in the actual venue.

How much space should you allow per guest?

For a comfortable seated dinner, including tables, chairs, and walkways, here are the standard benchmarks:

Excluding dance floor, stage, and buffet, which must be added separately.

Next, add the fixed elements: a dance floor for 100 guests is often 5 × 5 m, or 25 m². A 150 m² room for 100 seated guests at round tables quickly gets tight as soon as you add a dance floor.

Finally, keep about 1.50 m between tables. That is the space needed to push back chairs comfortably and allow staff to serve.

In Mariable: the room to scale

In Visual View, enable "To-Scale Room Setup":

• choose the shape of the room (rectangular, square, L-shaped, or U-shaped);
• enter its area in m² or its exact dimensions (width and length);
• add fixed elements: dance floor, stage or DJ, buffet or bar, catering access, each resizable by half a meter;
• display the 1.50 m comfort clearance around each table.

The tool then calculates how many guests your room can accommodate (round tables, banquet, or standing), after deducting the footprint of fixed elements. If you plan for more seats than the room allows, an alert appears: "room a bit tight for a comfortable dinner". You know this before signing with the furniture rental company, not on setup day.

Step 4: Seat your guests

Only now do you seat people. A few simple rules:

1. Start with the head table and close family/friends' tables, near the dance floor and close to you.
2. Group by "circles": each side's family, high school friends, colleagues. Then gently mix circles that share common interests.
3. Place families with children near an exit and away from speakers.
4. Save tricky situations for the end, once the rest is locked in.

In Mariable: two views to seat your guests

List View, for the bulk of seating assignments. Drag each guest from the "unseated" column to a table. If a table is full, the tool prevents placement and indicates its capacity. To remove someone, just drag them back to the column.

Visual View, for fine adjustments:

• click one guest, then another, and they swap seats, even if they are at different tables;
• click a guest, then a table with available seats, and they change tables;
• move tables around the room by clicking and dragging;
• zoom in, switch to a minimalist view (tables and counts only), or hide table names.

If you assigned colors to guests in your list (by family or group), they show up around their names on the layout. You can see at a glance whether a group has been split up.

Finally, a stats panel shows the number of seated and unseated guests, the total table capacity, and occupancy rate. When "unseated" reaches zero, you're done.

Step 5: Prepare documents for the caterer and wedding day

Your seating chart serves three parties: your guests (to find their seats), the caterer (to serve the right meal at the right table), and your day-of coordinator.

In Mariable: a PDF in one click

The "Export PDF" button, included in Mariable Couple (€29, one-time payment per wedding, no subscription), generates a single document in three parts:

1. An alphabetical guest list, with their assigned table. This is the one to display at the entrance: guests look up their name, not their table.
2. The table-by-table layout, including meals: for each guest, their dietary restrictions and notes ("Standard menu" if nothing special). This is the document to send to your caterer.
3. The overall room floor plan, on a single landscape A4 page, showing table positions and guest counts.

The plan is saved online. If a guest drops out the day before, simply remove them, export a new PDF, and send it over. No more "seating-chart-FINAL-v7.xlsx".

If you're working with a wedding planner

If your wedding planner or coordinator uses Mariable, the seating chart is linked to your wedding: both of you work on the exact same plan, including the room layout. No more back-and-forth emails wondering which file is current.

Step 6: Freeze it, then stop touching it

Set yourself a deadline, typically one to two weeks before the wedding, depending on what your caterer requests (check your contract). After that date, only adjust for last-minute cancellations.

A seating chart doesn't need to be perfect. Your guests will only spend about two hours at their tables, spending the rest of the evening mingling elsewhere.

Sticky notes, spreadsheets, or online tools: the comparison

What Mariable recommends

Don't start with seating. Start with the room. Most couples seat their guests first, only to discover at the rental company that their tables of 12 won't fit between the dance floor and the buffet. Take ten minutes to enter your room dimensions, add the dance floor, and verify capacity. Only then should you seat your guests.

And keep the decisions to yourself. A tool handles calculations, checks, and exports. Who sits next to your grandmother is entirely up to you.

FAQ: Online wedding seating chart

Is there free wedding seating chart software?

Yes. Mariable's seating chart tool is included in the free account: creating tables, importing guests (RSVP, list, or CSV file), drag-and-drop seating, and to-scale room view. It runs directly in your browser with no installation needed. PDF export (guest list, table menus, floor plan) is included in Mariable Couple for a one-time payment of €29.

How do you make a wedding seating chart easily?

Work in this order: confirmed guest list, table selection, venue check, seating assignments, and finally export. Using an online tool saves you from redoing everything with each change: move a guest in one click and regenerate the PDF.

What size round table for 8 people?

A round table for 8 people is usually 1.50 m in diameter. Count 1.20 m for 6 people, 1.80 m for 10, and 2 m for 12. Always verify exact dimensions with your venue or furniture rental provider.

What room size do you need for 100 guests?

For a seated dinner with round tables, count about 1.5 m² per guest, or 150 m² for 100 people. Add the dance floor (often 25 m²) and buffet. For rectangular tables, about 1.2 m² per person is sufficient.

Can you import a seating chart from Excel?

Yes. In Mariable, save your Excel or Google Sheets file as a CSV with a "Name" column (and optionally "Type", "Restrictions", and "Notes"), then import it. Your guests will land in the "unseated" column, ready to be placed.

When should you make your wedding seating chart?

Right after the RSVP deadline, which is typically 4 to 6 weeks before the wedding. Freeze it one to two weeks before, depending on your caterer's deadline, and then only adjust for last-minute cancellations.
