Think in zones, not just tables
At 150 guests, you can't intuit who sits where any more. The room is too big and the social graph too complex. Start by dividing the floor plan into zones rather than thinking table-by-table. Typical zones:
- → VIP / family zone — closest to the head table, 30–40 guests
- → Friends zone — middle of the room, ~60 guests
- → Work / wider network — further from the head table, ~30 guests
- → Kids zone — if applicable, adjacent to parents\' tables
- → Accessibility zone — guests with mobility needs near the entrance and washrooms
Table math at 150 guests
Three layout options:
- → Round 152cm × 8 seats: 19 guest tables + head table = 20 total
- → Round 183cm × 10 seats: 15 guest tables + head table = 16 total (uses less floor area but tables are larger)
- → Mixed: 8 round 10-seaters for family/friends + 8 round 8-seaters for the rest = 144 + sweetheart table
Reserve 8–12 seats of buffer. At 150 guests, expect 5–8 plus-ones to appear unannounced, and 3–5 cancellations in the final week.
Head table positioning
For 150 guests, a proper head table (couple + wedding party) makes visual sense — the room is large enough that a sweetheart table can look isolated. Position it on the long wall facing the room, with the dance floor visible behind it. Avoid the short wall: half the guests end up looking at the head table sideways.
VIP and elderly relatives
Grandparents and elderly relatives go at tables closest to the head table — they get the best view of speeches and the cake cutting, and they're closest to the catering exit (faster service, shorter walk for staff). Critically, place them far from speakers — 150-guest weddings often have louder bands, and the corner near the DJ is unkind to anyone over 70.
Kids' table — yes or no?
Below age 6: keep kids with parents. Ages 6–12: a dedicated kids' table works if you have 4+ children of similar age. Provide colouring books, kid-friendly food, and seat them within sight of their parents (adjacent table, not across the room). Above 12: most teens prefer to sit with adults — usually their parents or older cousins.
Accessibility — plan it, don't add it later
For wheelchair users and guests with mobility needs:
- → Aisle seats with at least 90cm of clearance for the chair
- → Close to the accessible entrance and accessible washroom
- → Not behind a column or pillar
- → If using a round table, remove one chair and slot the wheelchair into that position — don't make the guest sit at the corner
Logistics at scale
With 150 guests, your seating chart needs to talk to three external teams:
- 1. Catering — receives a per-table meal breakdown by Friday before the wedding
- 2. Venue staff — receives a master seating chart for door staff to direct guests
- 3. Stationery / signage — entrance display poster + place cards if used
Each of these needs its own export format. Seatly generates them all from one source: A4 binder PDF for the venue, per-table cards for catering, poster PDF for stationery.
