Every event planner asks the same question first: how many tables do I actually need? The honest answer is one table per 8 to 10 guests, biased a little higher for cocktail-style events and a little lower for sit-down dinners. The longer answer — and the one that actually saves you money — depends on your event format, the mix of casino games, and what else is competing for your guests' attention.
The one-table-per-8-to-10-guests rule
Casino tables seat between 6 and 10 players at any given moment, but real-world utilization is closer to half of seated capacity. People wander to the bar, the food, the photo booth, the dance floor. They go outside. They take a phone call. At any single moment, roughly 40–50% of your guests will be at the tables and the rest will be circulating. That's good — it means everyone gets a seat when they want one, and the room never feels stalled.
Plan one table per 8 to 10 guests and you'll have the right capacity for nearly any San Francisco casino party. Push to 1:7 if it's a sit-down format where guests stay put longer, and stretch to 1:12 if there's a strong competing attraction (a band, a dance floor, an open bar with bartenders pouring craft cocktails).
Recommended setup by guest count
Here are the configurations we ship most often for SF Bay Area events. Each assumes a 3–4 hour event with cocktail-style flow.
25 guests
- 2 tables — usually 1 blackjack and 1 craps or roulette.
- Works for: intimate birthday at home, small office mixer, rehearsal dinner.
- Floor space: roughly 20′ × 10′ (200 sq ft).
50 guests
- 4 tables — 2 blackjack, 1 roulette, 1 craps. Or 2 blackjack and 1 poker if guests skew toward serious players.
- Works for: 40th birthdays, small corporate offsites, wedding cocktail hour at a vineyard.
- Floor space: roughly 30′ × 20′ (600 sq ft).
75 guests
- 6 tables — 3 blackjack, 1 craps, 1 roulette, 1 poker.
- Works for: mid-size corporate events, milestone birthdays at City View, gallery weddings.
- Add a pit boss to the staffing — one person who isn't dealing helps the floor run smoothly above 4 tables.
100 guests
- 8 tables — 4 blackjack, 1 craps, 2 roulette, 1 poker.
- Works for: full-reception weddings, 50–75 person companies' holiday parties, school fundraisers.
- Floor space: roughly 50′ × 30′ (1,500 sq ft).
150 guests
- 12 tables — 6 blackjack, 2 craps, 2 roulette, 2 poker.
- Works for: ballroom weddings, mid-size company holiday parties at the Fairmont or Bently Reserve.
- Always include a dedicated event captain in addition to a pit boss at this scale.
200+ guests
- 15–20 tables — we scale the blackjack ratio up as guest count grows because it's the most welcoming game for newcomers.
- Works for: galas, large corporate events, the SF Mint, the Westin St. Francis.
- Plan on at least two pit bosses and an emcee for prize ceremonies and tournament announcements.
Getting the table mix right
For most San Francisco casino parties, half your tables should be blackjack. It seats 7, it's the easiest game to teach in 30 seconds, and it absorbs the largest share of guests at any moment. Roulette and craps are the "spectacle" games — one of each adds energy and gives non-players something fun to watch. Poker is the deepest game, perfect for tournaments and for guests who really want to play. Most events also benefit from one specialty table (three-card poker, baccarat, or a money wheel) for variety.
Floor space — the math venues care about
Each table needs roughly a 10′ × 10′ footprint to allow dealers and players to move comfortably. That includes the table itself (about 7′ for blackjack, 12′ for craps), the players standing or sitting around it, and a small buffer for foot traffic. For tight SF lofts and gallery spaces, we can compress to 8′ × 8′ per blackjack table, but it gets cramped quickly.
Adjust for competing attractions
If you have a live band, a serious DJ, a photo booth, and an open bar with three bartenders, your guests will rotate through more attractions and spend less time at any single station. Stretch your table count to 1:12 in that case. If casino tables are the main entertainment, lean toward 1:8 so there's never a meaningful wait.
