The answer hinges on one big question: are your canapés accompanying a meal, or replacing it? For a pre-dinner apéro, 3 to 5 bites per person are enough. For a 5 à 7 with no meal afterward, aim for 6 to 9. And for a cocktail-style reception standing in for dinner, plan 12 to 15 bites per person. Here’s how to adjust those benchmarks for duration, timing and guest profile, plus the mistakes to avoid that leave a party hungry at 8:30 p.m.
These are industry benchmarks: your caterer will fine-tune them to the actual menu, the richness of each bite and their experience with your type of event.
Beyond quantity, variety prevents fatigue: aim for roughly one-third cold bites, one-third hot and one-third substantial, with a sweet finish (1 or 2 bites per person within the total). Plan for about a quarter of your quantities to be vegetarian; even meat-eaters take them. Clearly label major allergens.
A networking 5 à 7 for 80 people, 5:00 to 7:30 p.m., open bar: 80 people × 8 bites = 640 bites across 5 or 6 varieties (including 2 vegetarian), served in waves over two hours. Add a pasta station and you can drop to 6 bites per person, for 480 in total.
Canapé math goes hand in hand with bar math. The most common benchmark: one drink per person per hour, a little more in the first hour. For dinner wine, plan about half a bottle per adult; a standard bottle pours five glasses. Also plan self-serve water and at least one appealing non-alcoholic option, such as a mocktail or house lemonade, which easily accounts for 10 to 20% of drinks nowadays. As with canapés, your caterer will fine-tune to the group’s profile.
If you order stations rather than bite, always ask how many pieces each platter holds and do the division yourself: a platter “for 10 people” sometimes holds 30 pieces (3 per person, apéro format) and sometimes 60 (meal format). The classic trap is counting platters instead of pieces; that’s how you run short even though the table looked full at the start.
Six hundred bites served in thirty minutes create a scrum, then a desert. Set a wave plan with the caterer: a generous pass as guests arrive, regular waves through the event, and a reserve for the final hour. If the event includes speeches or a presentation, pause service during those moments; half the bites served during a speech end up forgotten on table edges.
Sweets follow their own rules: 1 to 2 bites per person are enough as a cocktail finale, but a dessert bar as a centrepiece (wedding, prom, gala) calls for 3 or 4 per person across at least three varieties. Serve it late rather than early: it marks the festive peak of the evening and re-energizes the room just as the energy dips. The coffee and tea alongside are no afterthought; they’re often your guests’ last taste impression.
If you remember one rule: always round up. Between one platter too many and a guest still scanning the room for a server at 9 p.m., the choice is easy, and well-wrapped leftovers make for happy mornings after. Give your caterer the real numbers (confirmed attendance, duration, run of show) and let them translate: turning your guest list into the right quantities, no more and no less, is their craft.
12 to 15 per person, at least a third of them substantial. Below that, plan a late-night buffet as backup.
4 to 6 varieties for a 5 à 7, 8 to 10 for a full cocktail-style dinner. Too few gets monotonous; too many scatters production.
Count them as half an adult portion, and plan a few safe bets (mini pizzas, fruit) for them.
Too much, without hesitation: running out of food is the mistake guests remember. A reasonable margin is 5 to 10% above the calculation.
Yes — and better than anyone: give them the timing, duration, guest profile and run of show, and they’ll calibrate quantities to their menu.
