The Size of the Table

Size determines which moves and which positions are even available. Three quantities drive everything: channels (possible pairwise links — one at two people, three at three, ten at five, twenty-eight at eight), airtime (a fair share is 1/n of the clock), and audience (the size at which people stop talking to someone and start performing for everyone). Counts below include you.

Size by size

SizeWhat changesWatch forWhat dominates
Two
the interview
One channel, through you by definition — hub-and-spoke is the geometry, not a failure. Silence is at maximum power: the guest owns every pause. The cost: the guest never rests. Interrogation feel; no recovery time for the guest. Drawing Out, silence, the Second Answer; prep the person (Dossier).
Three
the first table
The triangle unlocks the Table group — Surfacing Difference and Cross-Pollinating exist for the first time — and guests get thinking time while the other speaks, which raises answer quality. Triads drift to two-against-one: the tribunal (you and A examining B) and the seesaw (you as tennis umpire). Rotate which pair is "on." Surfacing Difference, Cross-Pollinating, Bouncing the Ball.
Four
the conductor's sweet spot
Six channels, all still visible to one attentive host; the last size where a single conversation is guaranteed without enforcement. Coalitions (2v2) become real; the quiet-voice problem starts — with three guests, one can hide. Sequencing as an active duty, Inviting the Quiet Voice; prep the pairings (The Setup).
Five–six
the fission threshold
Spontaneous conversation supports about four active speakers; above that the table wants to split. You choose: hold one conversation (step up toward referee) or allow planned fission (let the ends split, then re-unite deliberately). Drifting between the two modes unconsciously. Airtime bites: ten minutes per person per hour. One loud register sets the table's key. Asking the Table, The Round, Registers; the Table Timer on a visible screen.
Seven–nine
enforcement or federation
One conversation exists only by enforcement — rounds, named turns, the referee position. Disclosure drops: everyone is performing for an audience now. Or embrace federation: side conversations become the resource and you route between them. Good quiet contributions dying in the noise; the shy guest seated after the comedian. Amplifying (highest value at this size), Harvesting across the split, structural Care; The Wheel.
Ten and up
architecture
The format does the hosting: panel plus hall, salon with a program, breakouts and reconvenes. Your live craft narrows to openings, transitions, whole-room moves, and time discipline — everything else was decided in the seating and the schedule. Believing you can conduct a hall the way you conduct a table. Prep the format: Run of Show, Participants, Event Packet. Donahue's roving mic and Question Time on The History of Hosting are the specialist crafts here.

Three patterns across sizes

The thresholds are moments, not gradients: the third person ends a certain intimacy, the fifth begins fission, the seventh ends spontaneity, and around twelve the single conversation ends no matter who is hosting.
