Between tables
Maintain the intended chair-back gap around every table. Check the tightest point, especially where rounds meet walls or diagonal furniture.
Round tables and room setup
Table capacity is the easy number. The useful question is how many occupied tables fit once chairs are pulled back, waiting staff can pass and the main aisle still reaches the stage, exits and service doors.
Hire stock and chair widths vary. Confirm the dimensions of the furniture that will actually be delivered.
| Nominal table size | Metric diameter | Typical comfortable seating | Possible tight seating | Best use |
|---|---|---|---|---|
| 4 ft round | 122 cm | 4–5 | 6 | Small parties, children, mixed table sizes or narrow rooms. |
| 5 ft round | 152 cm | 6–8 | 8 | A flexible standard where conversation and service both matter. |
| 5 ft 6 in round | About 165–168 cm | 8–10 | 10 | Common for weddings and dinners; efficient without feeling oversized. |
| 6 ft round | 183 cm | 10 | 12 | Large guest groups in rooms with generous spacing and broad aisles. |
The Metis capacity engine maps its standard rounds to real diameters: 4 ft, 5 ft, 5 ft 6 in and 6 ft. It then places chairs and clearances rather than treating each table as a bare circle.
A chair occupies more space when a guest is seated than when it is tucked under the table. Behind that chair, staff need a usable route; guests need to stand without pushing into another table. If two chair backs meet with no free gap, both tables may be technically drawn but neither is properly serviceable.
As a practical starting point, allow roughly 0.75–0.9 m (2 ft 6 in–3 ft) from a table edge to the back of an occupied chair. Then add free space behind the chair: around 0.45–0.6 m (1 ft 6 in–2 ft) for occasional passage, and more on active service routes. See the full banquet table spacing guide for diagrams and measurement methods.
One generous gap does not rescue a room with no connected route.
Maintain the intended chair-back gap around every table. Check the tightest point, especially where rounds meet walls or diagonal furniture.
Create loops from service doors to table zones so plated service and clearing do not depend on a single congested corridor.
Use wider, continuous routes for guest arrival, accessible movement, speeches and emergency planning. Do not let decorative furniture narrow them.
Keep a useful buffer between the first occupied chairs and the stage. Account for steps, speakers, screens and presenter access.
Leave clear access on more than one side. Chairs positioned tight to the floor are soon moved into aisles by guests.
Keep door swings, fire exits, columns, radiators and fixed bars visible while laying out the room.
Larger tables reduce the number of table centres but increase every table's occupied diameter. Smaller rounds offer more flexibility around columns and awkward edges, but create more service points, linen and centrepieces. The most efficient choice is often a deliberate mix, not one nominal size across the room.
For weddings, also decide whether the top table, sweetheart table and dance floor should form one focal wall or separate zones. For an awards dinner, protect views towards the stage before maximising the rear tables.
