8 ft × 18 in seminar table: Seating & Floor Space
Narrow tables for classroom and conference seating, not for dinner. Here is what it seats, how much floor it takes and how many you need for your guest count.
How many tables do you need?
| Guests | Tables at 3 each | Tables at 4 each |
|---|---|---|
| 20 | 7 | 5 |
| 50 | 17 | 13 |
| 100 | 34 | 25 |
| 150 | 50 | 38 |
Space and layout tips
Plan about 10 ft × 4 ft with chairs. Leave service aisles of about 4 to 5 feet between tables so servers and guests can pass behind seated chairs.
The comfortable number is better than the maximum for plated service. Squeezing 4 guests around a table limits elbow room and slows service.
