Seating Plan
A seating chart calculator helps you determine how many tables you need, how to fill them, and whether your venue can physically accommodate your guest count with the table sizes you’ve chosen.
The Core Formulas:
Tables Needed = ceil(Total Guests / Seats Per Table)
Floor Space Per Table (round) = pi × (Diameter / 2)^2 + circulation buffer
Standard Table Sizes:
| Table Type | Diameter / Size | Seats |
|---|---|---|
| Round 48" | 122 cm | 6–8 |
| Round 60" | 152 cm | 8–10 |
| Round 72" | 183 cm | 10–12 |
| Rectangular 6 ft | 183 × 76 cm | 6–8 |
| Rectangular 8 ft | 244 × 76 cm | 8–10 |
Circulation Rule: Allow at least 60 inches (152 cm) between table edges for comfortable guest and server movement. Fire codes typically require 36 inches (91 cm) minimum.
Worked Example:
- 120 guests attending
- 60" round tables seating 10 each
- Tables needed = ceil(120 / 10) = 12 tables
- Each 60" table needs ~1.8 m diameter + 1.5 m clearance on each side = ~4.8 m of space per table
- For 12 tables in a rectangular room: arrange 3 rows of 4 tables
Layout Tips:
- Reserve 1–2 seats per table for last-minute RSVPs or no-show swaps
- Place the head table or sweetheart table where it has clear sightlines to the dance floor
- Keep elderly guests and families with young children near exits
- Seat guests with dietary restrictions near the kitchen for easier service
- Number tables from the front: guests find lower numbers first
